Nootropics - their differences

Individual differences of action between Piracetam, Oxiracetam, Pramiracetam, and Aniracetam are often subtle, and in many studies they show similar modes of action.  One intriguing benefit I have seen reported only for Pramiracetam, is its ability to increase goal directed and purposive behavior (Branconnier 1983).  After trying Pramiracetam in my regimen several years ago. I did notice an increase in my tendency to quickly take care of routine household, auto and personal maintenance chores I habitually tended to ignore, avoid or postpone.

I have taken Piracetam for eight years, Pramiracetam and Aniracetam for the past two years and Oxiracetam for about 9 months. During the past year, my lifelong severe writer’s block has gradually disappeared, and my writing output of the past year has exceeded that of the previous decade. Some studies on dementia comparing Piracetam and Oxiracetam (the two most nearly identical racetams). have suggested that Oxiracetam may be more effective in restoring the cognitive deficits of dementia (decreased memory, concentration and alertness), while Piracetam may be more effective at normalising the emotional problems of dementia (agitation, tension-anxiety, hostility, insomnia, uncooperativeness).

Quantitatively, Piracetam is the least potent racetam, with clinical doses typically being 2400 mg to 4800 mg per day, occasionally even 6000 mg to I0,000 mg per day.

Oxiracetam is usually given 500 mg to 2400 mg per day. Aniracetam doses are typically 750 mg to 1500mg per day, while Pramiracetam has shown benefit even at 150 mg to 500 mg per day, although 600 mg to 1500 mg per day is more typical.

Piracetam and Oxiracetam are highly water soluble (96-98%), while Aniracetam and Pramiracetam are more fat soluble. Their lipophilicity may allow for less frequent dosing (once or twice daily) with Aniracetam and Pramiracetam, compared to 3 to 4 doses a day with Piracetam and Oxiracetam.

Aniracetam is favored by the Japanese, who have contributed much research on it. It is widely used there as an agent to rapidly promote clarity of thought.

My Brain Pills Test

As reported on the page “Brain Supplements,” I ordered a month supply of Constant Focus - one of the many “brain pills” out there. I did a quick mental test before starting to take the supplements around the start of April 2009. It consisted of mentally multiplying ten sets of two two digit numbers (64 x 96, etc). I generated the digits randomly using 1 through 9 (including 0 would have made it too easy). I did not allow myself pen or paper except to write down the solutions.

I recorded both the time it took to do the ten equations and the accuracy. I did two tests (20 equations total) before and two after taking the pills for 30 days. Both of the latter tests were more accurate and completed faster than the first two. Here is what the results looked like:

Control Test 1: (8:17 to complete - 70% correct)
Control Test 2: (6:47 to complete - 80% correct)

Results Test 1: (5:24 to complete - 80% correct)
Results Test 2: (5:20 to complete - 90% correct)

Constant focus claims their product can help you “Boost the efficiency of your work,” and “Realize your full mental potential.” The tests I did might measure these vague claims in part. I didn’t test for other claims like increased attention span. Unfortunately, I do not consider the results very good evidence for a variety of reasons. First, too many factors affect one’s mental performance on a day-to-day basis.

More specifically, my wife and I had already planned a cleansing diet for a two-week period that happened to be in April. I suspect that this and my heavier-than-normal mental workload got my brain functioning better. This points to the difficulty of this kind of self-experimentation. It is tough to stop life and control all variables in order to have a more accurate test. For what it is worth, I didn’t feel like there was a dramatic difference in my thinking, although the test results surprised me.

Other Problems

As I mentioned in the Brainpower Newsletter, brain pills may often work solely because of the vitamins and minerals that are put in them, since most of us probably have some deficiencies.Also, if they are packed full of cheap vitamins, how much room is left in the capsules for the true brain-improving elements? I chose to try Constant Focus because the web site listed just seven ingredients: ginkgo biloba, vinpocetine (biovinca), huperzia serrata (huperzine A), gotu kola, choline, carnosic acid (rosemary leaf extract), phosphatidyl serine (LECI-PSR).

In fact, after the list of ingredients, the site said this: “Of course, we could add more ingredients. We could turn Constant Focus into a 50-ingredient multivitamin like some of our competitors offer. But we believe that if you want vitamins, you’ll take vitamins. If you want to enhance your mental performance, to take yourself to the next level, you’ll try Constant Focus.” Unfortunately, when I looked at the ingredients listed on the actual bottle, there were ten vitamins and minerals included.

Furthermore, I bought a 30-day supply - that’s how it was described on the site. But the bottle says to take three capsules in the morning, and then adds, “an additional three capsules can be taken in the afternoon.” That would make it a fifteen-day supply, which comes to almost $4 per day at the price I paid with shipping.

An Alternative

I don’t care for that kind of misleading marketing, and I am not sure how much of an effect these brain pills had in any case. Since I have tried vinpocetine (one of the ingredients) before and seemed to get a brain boost from it, and I can use that for the equivalent of ten cents-per-day, I am inclined to try that along with a vitamin supplement. The total cost might be as high as 30 cents daily for possibly the same small effect. That’s less than a tenth of the cost.

My recommendation? There are cheaper “brain pills” to try, and I think we shouldn’t encourage those who use misleading marketing, so skip the Constant Focus.

Brain Foods

What are “brain foods?” They are any foods which improve brain function in some way. A diet heavy in omega-3 fatty acids, for example, can help keep the blood vessels of the brain clear of blockages and allow nerve cells to function at a high level. So you may want to eat your fish twice a week (A major source of omega-3s) or take a supplement.

It is equally important, however, to recognize the foods that diminish brain power. Alcohol and some other drugs just kill brain cells directly, but there are many less obvious brain-attacking foods. Artery clogging foods can lead to restricted blood flow to the brain, and high-glycemic-index foods can cause terrible blood-sugar swings that make both your body and your mind irritable and sluggish.

For the impatient among you, I’ll skip straight to the list of good brain foods and foods that are bad for mental function. Afterwards you’ll find a more thorough explanation, if you want it.

Good Brain Foods

Avocados
Bananas
Beef, lean
Brewer’s yeast
Broccoli
Brown rice
Brussels sprouts
Cantaloupe
Cheese
Chicken
Collard greens
Eggs
Flaxseed oil
Legumes
Milk
Oatmeal
Oranges
Peanut butter
Peas
Potatoes
Romaine lettuce
Salmon
Soybeans
Spinach
Tuna
Turkey
Wheat germ
Yogurt

Bad Brain Foods

Alcohol
Artificial food colorings
Artificial sweeteners
Colas
Corn syrup
Frostings
High-sugar “drinks”
Hydrogenated fats
Junk sugars
Nicotine
Overeating
White bread

Brain Foods Explained

As mentioned, alcohol just goes in and starts killing brain cells. Nicotine causes constriction of capillaries, which restricts blood flow to the brain, which reduces the delivery of good things like glucose and oxygen. Hydrogenated fats are more subtle, causing heart disease and general clogging of the arteries that eventually results in the same effects long-term as the short-term effect of nicotine. Since all three of these can kill you in addition to hurting your brain, you may want to replace them with healthy foods and drinks.

Artificial colorings and flavorings have their own bad effects according to many studies, especially in children. The rest of the foods on the “bad brain foods” list are bad because of the unhealthy fluctuations in blood sugar levels they cause. If you don’t want to memorize the list, just remember to stay away from all drugs, refined flour and sugar products (potatoes aren’t so good either, if you overdo it). Let me explain further.

Your brain runs on blood sugar, using an incredible 20% of the carbohydrates you take in. It prefers to take it’s blood sugar in a certain way, however. Simply put, it likes a steady supply, and dislikes wild fluctuations. Simple carbohydrates - processed flour products and sugary foods - cause wild fluctuations. These cause a rush of sugar into the bloodstream, which triggers a balancing rush of insulin, leading to a plunging blood sugar level (hypoglycemia ). This can cause the release of adrenal hormones (called a “sugar high”) that squeezes stored sugar from the liver, sending blood sugar levels back up.

Now you’re on a blood sugar roller-coaster, with “sugar highs”and “sugar blues.” The ups and downs of blood sugar and adrenal hormones can also stimulate neurotransmitter imbalance, causing you to feel fidgety, irritable, inattentive, and even sleepy. This is not the most conducive state for efficient brain function. Since simple carbohydrates have been implicated in diabetes as well, you may want to consider cutting back on these.

Good Foods for the Brain

The best brain foods are complex carbohydrates. The molecules in these are long, so it takes longer for the intestines to break them down into the simple sugars the body can use. Because of this, they provide a source of steady energy rather than a surge followed by a plunge.

The rate at which sugar from a food enters brain cells and other cells is measured by the “glycemic index” (GI). Foods with a high glycemic index stimulate the pancreas to secrete a lot of insulin , which starts the roller coaster. Foods with a low glycemic index don’t push the pancreas to secrete much insulin, so blood sugar levels are steadier.

Fruits: grapefruit, apples, cherries, oranges, and grapes have a low glycemic index. Whole fruit ranks lower than juices, because fiber in the fruit slows the absorption of fruit sugar.

Cereals and grains: oatmeal and bran are best. Spaghetti and rice have a relatively low GI. Corn flakes sugar-coated cereals, and white bread have higher GIs.

Vegetables and legumes: Legumes, including soybeans, kidney beans, chick peas, and lentils are great brain foods. They have the lowest glycemic index of any food. Potatoes and carrots have a much higher GI.

Dairy products: Milk products have low glycemic indexes; higher than legumes, but lower than fruits.

How you prepare and eat your food also affects the way the body and brain uses it. Eating sugary food after a meal of legumes, for example, may slow the absorption of the sugar and prevent the “sugar blues.” Fats can also slow sugar absorption, so ice cream will have a lower glycemic index than low fat yogurt with sugary fruit. Over-cooking some starches can be similar to pre-digesting them, thus causing them to feed their sugars into the blood too quickly.

Proteins affect brain performance because they provide amino acids, from which neurotransmitters are made. Neurotransmitters carry signals from one brain cell to another. The better you feed these messengers, the more efficiently they deliver the goods. The amino acids tryptophan and tyrosine, are precursors of neurotransmitters, the substances from which neurotransmitters are made. Tryptophan is an essential amino acid and it must be obtained from the diet. Tyrosine is not an essential amino acid because the body can make it if need be.

Some high protein, low carbohydrate, high tyrosine foods that are likely to rev up the brain are seafood, meat, eggs, soy, and dairy. High carbohydrate, low protein, high tryptophan foods that are likely to calm the brain include: pastries and desserts, bean burritos, chocolate, nuts and seeds (e.g., almonds, filberts, sunflower and sesame seeds), and legumes.

From here it just gets complicated. People respond differently to differing ratios of protein to carbohydrates in meals, and there are also subtle sensitivities (not quite allergies) to foods that vary from person to person. Experimentation is called for, and since it is your body, you have to do it yourself.

A Final Note

In studies, children scored higher on tests when on a regimen of daily vitamin supplements. “Experts” will tell you that if you eat a balanced diet, you don’t need supplements, which, given the culture here, is really just a sales pitch for vitamins here, isn’t it? Who eats a perfectly balanced diet?

A final, final note. Putting the right food in helps, but it’s important to get it out too. That’s why I nominate fiber as the unsung brain food hero. I don’t know how many times I’ve heard or read about somebody’s mind clearing up once their system was cleaned out. When the research is eventually done in this area, I suspect that it will show definite brain benefits from having a digestive/elimination system that works efficiently.

How to stop feeling tired
  1. See a doctor
    If you are constantly tired—meaning every day and all day—then you must seek professional help, because these are warning signs. You must rule out a medical condition such as sleep apnea, clinical depression, drug withdrawal symptoms (not just street drugs, but something you might have been on prescription for), diabetes and others. Ignoring a medical diagnosis and juicing yourself on uppers can kill you
  2. Yawn
    It stimulates the precuneus in the pareital lobe. Not only is yawning relaxing, it also heightens awareness
  3. Correct your posture
    Stop slouching and sit up straight. This is the first “brain hack” to try, because changing to a posture that physically resembles alertness can pull the rest of you with it. You should also try standing up and walking around for a few minutes
  4. Drink tea, not coffee, before noon
    High doses of caffeine in the morning puts you on a chemical roller coaster that dips in the afternoon. Tea has a lower dose that’s released more slowly
  5. Take caffeine in a series of small doses
    A study found that caffeine was most effective when taken in small doses over time, rather than in huge doses all at once
  6. Lunch = Protein + Fiber - Carbs
    Lots of carbohydrates in the form of pasta, noodles, white bread, white rice, potatoes and sugar will give you a spike in your blood sugar level, which will induce your body to secrete insulin. The following “sugar crash” will make you feel exhausted an hour or two later. Stick to proteins and fiber foods at lunchtime (a BLT in a wholewheat roll or wrap, for example) and save the potatoes and pasta for dinner in the evening so that you sleep well and wake up without a deficit that you have to correct with naps the next day
  7. Lots of B6 and B12
    Doctors recommend taking lots of B6 as a natural way to suppress fatigue. I’ve had ER physicians recommend woofing down as much as I like (though obviously not entire jars of pills at a time) because it’s water soluble and your body will flush any excess that it doesn’t need. Synthetic B12 (cyanocobalamin) is another energy booster that won’t make you crash a few hours later, like caffeine does
  8. Take a walk
    Although exercise is a short-term way to wake you up, a long-term commitment to exercise is going to improve the strength of your cardiovascular system, which in turn will make it easier for you to metabolize fat and glucose energy. Try getting up earlier in the morning and going for a 20-minute walk before heading to work, because this will keep your heart rate elevated all day
  9. Let the sun in
    Open the blinds if you have a window, or get outside if it’s sunny. Your brain is tuned to interpret light and dark conditions as signals to wake up or go to sleep
  10. Don’t use downers at night
    You think that if you take a sleeping pill now then you’ll get a good night’s sleep and feel refreshed in the morning. But the reality is that taking a sleeping pill will sedate you and rob you of enough REM sleep. A sleeping pill will knock you unconscious but your night will be unfulfilling, so you’ll feel drowsy all day the next day. The same goes for alcohol, which is another depressant that will knock you out but won’t give you restful sleep
  11. Take 40 winks
    It’s normal to feel tired in the afternoon, even if you’ve avoided a big lunch, and it’s healthy to take a nap if you do. But limit naps to 30-40 minutes because longer naps can push you so far into a sleep cycle that you end up feeling drowsy instead of refreshed once its over

The Stimulants

  • Caffeine
    Works because one of its metabolites is an adenosine antagonist, and adenosine is a brain cell’s way of saying “I’m pooped, stop talking to me”. When caffeine’s byproduct attaches to adenosine receptors on nerve cells it blocks the signal and prevents the cell from going to sleep when its neighbors start to yawn. Caffeine also suppresses signals in the vegus nerve—which regulates heartbeat—and suppressing the vegus nerve makes your heart beat faster
  • Sulbutiamine
    A variant of Vitamin B1 that can cross the blood-brain barrier because it’s fat soluble. It’s used by athletes as a stimulant and energy booster
  • Amphetamines (Adderall, Ritalin and others)
    Work by increasing the levels of norepinephrine, dopamine and serotonin in the brain, producing euphoria
  • Modafinil
    The mechanism is still not well known, but the drug is now prescribed for narcoleptics and those with EDS (Excessive Daytime Sleepiness) or Shift Work Sleep Disorder (third-shifters working at night). This is a prescription drug in the United States, available by mail-order without a prescription by some firms on the Internet. See my related article.

How to get smarter
 If you weren’t born smart, then you’ll have to work at it. Assuming there’s nothing seriously wrong with you, like amyotrophic lateral sclerosis, then there’s only five things you really need to do:
  1. Exercise
  2. Eat fresh fish and vegetables
  3. Read
  4. Teach
  5. Risk

1. Exercise

 My article on nootropics will do you no good if you’re physically unfit. It isn’t necessary to have a model’s physique, but it is necessary to have a heart that can really pump blood and lungs that can really breathe air.
 Research on both man and mouse has uncovered an improvement in cognitive function after aerobic exercise, from running to brisk walking. Weight lifting, while important in a fitness regimen, did not lead to a measurable, sustained cognitive boost the way that running did.

2. Eat fresh fish and vegetables

 The fatty acids in fish oil (called the “omegas”) are used to construct the myelin sheath of each brain cell. There are other sources for it, which you should find and add to your diet, but fish is a habit you want to keep. 
 The vegetables are for the vitamins, iodine and fiber. The vitamins and iodine are critical building blocks for the brain, too, and the fiber makes sure all that crap going through your digestive system gets flushed out properly instead of hanging around and poisoning you.
 It’s funny how an article that aims to make you smarter first tries to make you healthier, but it’s about as funny as curing cancer by first getting the patient to quit smoking. Artists are taught that every change in a model’s pose affects every other part of the body—you move a leg, and the flesh shifts across the waist and tugs differently on the arms. Your body and your mind are not so separate either, they’re not house and occupant, a change somewhere in your body means a change somewhere in your mind.

3. Read

 Just the act itself matters, and not just what you read. Although it can likely benefit you materially if you read about the things that concern your profession, and it’ll likely benefit you cognitively if you read things that challenge you: logically, mathematically, philosophically, politically challenging. You’ll benefit just from the act of reading. But here you are, reading already, so now it’s time to look for books that’ll tell you something you didn’t already know. Look for books that might tell you something that’ll still matter even if your profession is made redundant by machines someday, or a shift in the economy. 
 Subscribe to Nature, you can afford it even if you think you can’t. Then try to understand the articles. Go to Wikipedia or a search engine every time you read a term or a word you don’t understand. Struggle, it’ll be hard. And then one day you’ll know what a transcription factor is, or adenosine triphosphate, and your IQ will have gone up not because you’ve now memorized something, but because you’ve exercised learning and comprehension mechanisms in your brain and they’re getting better at it.

4. Teach

 Teaching is the other side of reading, because it’s the QA—or “Quality Assurance”—phase. Teaching as a job is not what I mean, though. This would be teaching accidentally, or incidentally. Explain how something works to someone. Get your drinking buddy and explain the carbon cycle to them. And if they ask you a question you don’t know the answer for, or you find you can’t explain it after all, then you didn’t really know it, did you? Don’t be embarrassed, just go “aw, fuck” and hit the books again. 
 Plan a lesson in your mind, and practice teaching to your shadow. Imagine someone asking “why?” at every point you were going to gloss over, and go back to the books until you can answer it.
 ”Pics, or it didn’t happen” is what they say about grand claims. “Teach, or you don’t know it” is the analogue.

5. Risk

 And likewise you’ll never really know—and never really think—until you act on it. Take the plunge sometime. Accept the possibility of screwing up and losing something and do it anyway. You must put yourself in the position you have to be in for your mind to do what evolution designed it to do: think fast and creatively to save your ass from trouble. Until you’ve been there, you have no idea what thinking really is, and you’ll never be smart.

Other things that seem to help

  • Daydreaming - Chinese scientists studied the resting state of volunteers as they lay in an fMRI (functional Magneto-Resistance Imaging) machine—a tool that can graph the activity of the brain—and compared the activity of subjects with average IQ to those with higher IQ. They saw a higher level of communication between distant brain regions in the smart people than the average. The “idle” mind daydreams, and it seems the more of it then the smarter the daydreamer is. It isn’t known yet if increased daydreaming leads to higher IQ, or a higher IQ tends to lead to more daydreaming, although it is known that practicing mental tasks does create new connections between neurons

  • Talking to yourself - either out loud or by writing down a clear explanation of your problem will force you to convert your perception of a problem from vague and nebulous feelings and intuitions into concrete, absolute words and sentences. Maybe it’s embarrassing when someone catches you in the act of talking to yourself out loud, but it doesn’t just exercise multiple parts of your brain (memory, language composition, motor control, language comprehension, among others) it also invokes computation and problem solving skills. Explaining a problem to someone—or just yourself—will either jolt the answer out of the blue, or make you re-frame it in a way that’s easier to analyze

Nootropics: their effects, their risks, and where to get them (With the perspectives of a user)

 Ten years ago I went on a quest to become an expert on coffee and to sample as many different ways of making it and as many different varieties that existed. I tried everything from the French Press to the Coffee Siphon, Hawaiian Kona to Jamaican Blue Mountain. But unsatisfied with mere coffee, I went on a quest to find out how to use chemicals to enhance my mind. It had its roots in old high-school days when I’d bring a sixpack of Jolt cola to a computer-programming marathon: cramming together study halls and lunch breaks in my senior year. The nootropics of that era were caffeine, sugar, cortisol, dopamine, epinephrine and norepineprhine, and the last four in that list were all natural hormones my body was making itself. 
 The first “smart drug” I heard about was Modafinil, which was described as a pill that could let you stay awake without fatigue for 48 hours, sleep for 8, and then repeat the experience again indefinitely. Modafinil can do that under the right circumstances, but it turns out that it was not a drug that would turn you into a superthinker overnight. “Moda” was to be just one of many substances I’d experience firsthand.
 Take apart the word “Nootropic” and you get fragments of Greek words that mean “affecting the mind”, but the word is used to label drugs that affect the brain in what we expect is a good way. Each of the drugs described below will have a physiological effect, and my list does not cover substances that bear no published or firsthand evidence of such.
 Some of the drugs described below are dangerous, and you must not take them until you have seen a doctor for a physical exam and a psychiatrist for a mental health exam. Both exams are important: one of the drugs below affects homeostasis and can kill someone who isn’t in good physical condition. Others affect the production of neurotransmitters, and if you have a mental illness such as depression then they can exacerbate the disease or interfere with its treatment. 
 The first drugs on our list are commonly regarded as basic nutrients or dietary supplements and aren’t harmful. The list will then progress to the stronger substances that I’ve tried.
 I haven’t been paid by any of the companies mentioned in this article, but the Amazon links do pay me a percentage. The advertising accompanying this site is Google’s AdSense. Where I’ve listed a retailer to purchase from, it means I have bought that drug from them for personal use.
 So that said, beginning with the harmless and escalating in order of increasing risk:

Iodine

 A critical nutrient, the lack of which leads to mental retardation. It isn’t typically included in lists of smart drugs, but it needs to be for two good reasons. The first is that iodine deficiency is responsible for more unrealized intellect worldwide than any other nutritional factor, and populations with poor nutrition can be 10 or 15 IQ points behind the average. The second is that even in western nations you can have an iodine deficiency and not know it. Most westerners get their iodine from iodized salt and enriched flour, But if you prefer to use non-iodized flour or salt for cooking, and you live in an area with low soil iodine levels, then you may not be getting enough.
 Iodine is part of the process of making thyroid hormones, and it’s here that a deficiency leads not only to retardation but also to goiter. Iodine also acts as an antioxidant (one of the first in biological history—its presence in early blue-green algae made it possible for them to produce oxygen without poisoning themselves in the process, and led to Earth having an oxygen-rich atmosphere).

Where to get it

 If you are not using iodized salt or enriched flour, then you and your children need to take iodine supplements. Most once-a-day multivitamin pills contain plenty, but check the label because some don’t.

When and how often

 Every morning or with a meal.

Vitamin B1 (Thiamine)

 Used to treat alcoholics and sleep-apnea patients with memory loss, as it helps to rebuild neurons—particularly those in the mamillary bodies of the hypothalamus in the brain.

Where to get it

 Pork and yeast have the highest natural concentrations, but most of us get it from cereals (wheat, corn, rice, etc.) In pill form, you can find it in any supermarket or drugstore’s nutritional supplements aisle.

When and how often

 Every morning or with a meal.

Piracetam and Friends

 A memory enhancer. The racetams (“ra-see-tam”) are the first drugs to inspire the term Nootropic, and the trade-name for Piracetam is Nootropil. At the time of writing, their physical effect is believed to be similar to acetylcholinesterase inhibitors, meaning that it disables the action of an enzyme that deactivates a neurotransmitter called acetylcholine. The judicial suppression of this enzyme can lead to greater memory retention. Racetams now come in a large number of formulations, which although they vary at the molecular level, are all based on the same chemical theme and all have the same effect in different degrees. Those on the market are:
  • Piracetam
  • Aniracetam
  • Oxiracetam
  • Pramiracetam
 All are unregulated in the United States and sold over-the-counter as nutritional supplements. You’re unlikely to find them in nutrition stores like GNC or Vitamin World, but all variants are easily found for sale on the Internet.
 The differences between the varieties come down to whether they are fat soluble or not, which affects how easily they cross the blood-brain barrier. To you, the matter is not of effectiveness but of convenience. Piracetam is water soluble and extremely cheap ($20 buys a large tub of Piracetam powder, of about 500 doses worth, and which dissolves easily into any beverage), but Oxiracetam and Pramiracetam are fat soluble (add cream to your drink before you dissolve them, if you bought powered forms) and proportionately more effective. Whichever you chose you will get the same bang for the buck.
 The racetams are also called cognitive enhancers, but this is a subjective term used when advertising them. Studies of the drug have only tested for, and revealed improvements to memory.
 Recetams are currently considered to be risk free, hence their unregulated status. There are no immediate negative side effects, and—at the time of writing—no studies have exposed any long-term negative side-effects. 
 If you buy a tub of oxiracetam powder and take a teaspoonful, it’ll probably have the taste and texture of sugar. But buy it from a reputable source and you won’t have been ripped-off. There is a patented method for manufacturing drugs in a form that resembles and tastes like sugar. Piracetam in powdered form tastes like nasty sugar, so try mixing it with chocolate milk or a citrus drink.

Where to get it

 I have purchased and used Piracetam from the following sources:

When and how often

 Users have recommended taking a quadruple-dose 30 minutes before a study session, then taking regular doses every 2-4 hours afterward. Piracetam’s suggested regular dose is 800mg (one pill, but check). I have not experienced any side-effects after doses of 3,200mg at one time, but remember that Aniracetam and other formulations are more potent and require lower dosages. The ‘racetam family haven’t been proven effective as a daily supplement, so their usage ought to be restricted to study sessions specifically.

Creatine

 An IQ booster. Creatine is already very popular with bodybuilders, and this makes it extremely easy and cheap to obtain. There are dozens of manufacturers and it’s sold everywhere that dietary supplements are.  It occurs naturally in your body and improves the supply of energy to your muscles. It has been found safe in doses of up to 20 grams per day, but there are known problems in those with kidney and liver disease, as well as those with diabetes or hypoglycemia. Add to that its tendency to increase the production of formaldehyde with long-term use. Its popularity with bodybuilders comes from giving them the ability to do more in a workout, leading to an increase of muscle tissue.
 Its nootropic effects come from its effect on the production of Adinosine Triphosphate—the chemical energy that drives cellular activity. This makes it a type of stimulant, and in studies it was found to improve results in tests of fluid intelligence, which is the ability to find meaning in confusion, draw inferences, make symbolic connections, and solve problems. This is compared to crystalized intelligence, such as when you learn how to add, or tie your shoelaces. These studies were performed on vegetarians in order to isolate the effects of the supplement with natural creatine in meat.
 Creatine supplements come in two chemical forms: Creatine monophosphate and Creatine ethyl ester. The latter, CEE, is supposed to have higher absorption rates and half-life, but there haven’t been any studies that bear this as true. In fact, the addition of the ethyl group appears to hasten its breakdown and instability, meaning that you’re better off with the monophosphate variety.

Creatine and Piracetam

 Recently there’s been buzz that Piracetam can be given an extra boost from Creatine supplements. I have not yet found any studies that show or explain the link between the two, however.

Where to get it

When and how often

 Creatine is a supplement that can be taken daily. Take two 750mg capsules two to three times per day.

Sulbutiamine

 Is a stimulant as well as a memory enhancer. It’s a chemical variant of vitamin B1, and the crucial difference is that it can cross the blood-brain barrier better than conventional B1 (thiamine). The B-family of vitamins tend to be stimulants because of their role in the metabolism of stored energy, and the more sensitive you are to stimulants such as caffeine, the more sensitive you’re likely to be to the B vitamins, including Sulbutiamine.
 It’s sold over-the-counter in powder form. It’s better to get it in pill form, if you can, for it has a bitter taste and is hard to mix with drinks without making them taste nasty.
 Note: The nutritional supplement company Fast 400 has been selling Sulbutiamine as Sublutiamine, apparently a typo that they haven’t fixed. It is the same substance, however.

Where to get it

 I’ve noticed an increasing trend to pull pure Sulbutiamine off the market and retail it as a cocktail instead. The following are where I’ve purchased pure Sulbutiamine in the past, and Your Results May Vary.

When and how often

 As needed for a stimulant. I have experienced nausea with doses of 800mg.

Centrophenoxine (Meclofenoxate)

 A memory enhancer first used to treat Alzheimer’s disease and senile dementia in the elderly. There’s been a rush to raid the Alzheimer medicine cabinet, lately, in the hopes that what will make the senile keep their memory will make the healthy get even smarter, Centrophenoxine is the poster child of this movement. The chemical itself is a compound made from one naturally occurring substance—dimethylaminoethanol (DMAE)—and one synthetic, which is parachlorophenoxyacetate (pCPA). Exactly how it improves memory isn’t known, but there are two leads: 1) it’s a precursor to the neurotransmitter acetylcholine and may increase levels of it in the brain, and 2) it removes lipofuscin deposits in the brain and skin. 
 Lipofuscin on the skin lead to “liver spots”, while its build-up in the brain is suspected to be behind the “plaques” that are observed in brain tissue samples taken from Alzheimer’s patients. The theory for Alzheimers is that the lipofuscin clogs ion channels on the surface of nerve cells,  preventing the movement of potassium through these channels and degrading memory and cognition in the process. 
 Centrophenoxine gave the author mild nausea when it was taken on an empty stomach, but not when taken with food. Avoid it completely if you suffer from high blood pressure or epilepsy. It’s available over-the-counter from nutritional stores, but usually only those on the Internet. Like with the racetams and Sulbutiamine, I have not seen it in main-street nutrition stores.

Where to get it

When and how often

 Centrophenoxine’s benefit comes from preventative maintenance. Take 250 to 500mg per day in the morning with breakfast.

Modafinil (Provigil / Alertec)

Quackery

Ginko Biloba

Is bunk. It’s still marketed as a memory enhancing herbal supplement, but its banner test case—Alzheimer’s—turned up squat. Other findings conducted on healthy adults and published in JAMA also concluded that the supplement has no effect on long-term memory.
 Now we’re cooking with gas. It was first prescribed to narcoleptics to help them stay awake during the day, and then used by the Navy and Air Force to help pilots stay alert on long missions. Modafinil keeps you awake and alert, has an effectiveness that spans up to 8 hours, and increases the capacity of your working memory. It remains prescription-only in the United States, and any US resident would need to either obtain a prescription from a doctor, or purchase it from a foreign supplier. 
 Modafinil increases the level of dopamine in the brain, and is therefore potentially addictive. I will go out on a limb to say I’ve not developed an addiction to it, in spite of taking it frequently, but this is only my experience. Do not take Modafinil if you have cirrhosis of the liver or heart disease, and do not mix it with alcohol.
 Because this list is given in order of increasing risk, I’ll point out that Modafinil is our turning point between unregulated “nutritional supplements” and drugs that are powerful enough to stay behind the counter. From Modafinil and onwards in this list, you will not want to take these if you are pregnant, breastfeeding, or have not received a physical exam from a doctor in the past year.
 As yet, few side effects are known that would threaten your health. But since 1998, the FDA has seen several cases of dermatologic (skin) reactions to Modafinil, some severe enough to require hospitalization. I have only experienced mild headaches and stomach discomfort, however.
 Modafinil is broken down by the liver enzyme CYP 3A4, and 3A4 itself is inhibited by the naturally occurring chemicals found in grapefruit juice. Doctors who prescribe Modafinil therefore warn their patients against drinking grapefruit juice while they’re on the medication (and as it happens, many other drugs are broken down by 3A4 and are similarly affected). Given that Modafinil has low overdose potential, the author tried deliberately taking it with grapefruit juice but did not perceive a change in effect.
 Modafinil can promote wakefulness without the jitters of caffeine, and under the right conditions can let you stay awake for 48-hours without feeling excessively sleepy. But taking it doesn’t mean you’ll suddenly be fatigue-free and spend the next two days wide awake; Modafinil—used as a nootropic—helps those who already have a good sleep pattern. The author was not able to dispatch sleep by popping a few pills, but he was able to perform and concentrate superbly under its influence for hours at a time.
 Take about 100mg for every 100lbs of body weight, anything less and you won’t feel much of a difference. If you take the right dose then in about an hour you’ll start to feel a subtle buzz, like someone swapped the battery in your brain with one that has a higher voltage. Take the first dose in the morning, and—if necessary—a second dose in the afternoon. While some have used it to pull all-nighters, you can’t use it to eliminate sleep—there’s no drug which can do that. Nor should you take it every day for nootropic use, because your body will adjust and require higher doses to get the same effect. My practice is to use it no more than once a week on a day that I’ve set aside for an important project.
 If you want to take it for nootropic effect then don’t take it when you feel tired, because while it will lift you out of your stupor it will just be an expensive way to get the same effect as a nap and a cup of coffee.
 Modafinil is far and away the superior alertness drug, but it is expensive. A 30x100mg package of Progivil will cost around US$175, while the licensed brand Alertec is at least $140. The author suggests talking to your doctor (it is prescribed for excessive daytime sleepiness caused by third-shift work or sleep apnea), or purchasing it from an overseas supplier. 
 Beware of firms that advertise prices significantly lower than the above, because you will probably not get the real thing. The author very nearly got ripped off by a firm that was advertising 100x200mg packages for $90. These will come from countries that manufacture it generically despite the patent.
 About 2-3 hours after taking a dose of Modafinil you will notice a change in the odor of your urine—somewhat like the odor after eating asparagus. This is normal and caused by the sulphur metabolites of the drug when your body breaks it down.
 Generic modafinil should become available in 2012, but this is only after generic drug makers contested Cephalon’s patents that cover both modafinil itself and its formulation as a drug. It may not go truly generic until 2015.

Adrafinil (Olmifon) and other formulations

 Adrafinil is Modafinil lite, but specifically a prodrug that your body will metabolize into Modafinil in vivo. It’s both cheaper than Modafinil and unregulated in the United States, but you have to take a much larger dosage to get the same effect. Being unregulated doesn’t mean it’s available over-the-counter at your local drugstore, though; you’ll still need to order it over the Internet.
 As a cautionary note, Adrafinil is harder on your liver than Modafinil is. I don’t yet know if it’s because its metabolites are toxic, or because the liver has to do more work to convert it into Modafinil on its way to being broken down entirely, but it would be unwise to take this drug (or any drug not directly prescribed) if you have liver problems.
 Cephalon has also introduced a similar drug called Nuvigil (Armodafinil), which is the right-hand enantiomer of Modafinil—another way of saying it’s Modafinil’s sister, or what you get when the molecule is flipped back-to-front like a mirror image. Many drugs fit into this class called stereoisomers, where the drug molecule comes in “left hand” and “right hand” shapes. Sometimes the two enantiomers have the same physiological effect in the body, and when the patent is due to expire on the “left hand” version the Pharmacy company patents and begins selling the right-hand version. The popular heartburn medicine Prilosec (Omeprazole), for example, has an identically functioning twin sister called Nexium (Esomeprazole), but while you can now get generic Omeprazole OTC, Nexium is still a patented drug sold by prescription.
 And this is what Armodafinil is. So far it seems to have the same effect as Modafinil, but the looming 2012 availability of generic Modafinil has spurred Cephalon to market Armodafinil (Nuvigil) as a “better” version for a broader range of ailments (including bipolar disorder and schizophrenia). 

Where to get it

  • Your doctor, by prescription
  • Biogenesis Antiaging - They will sell it to you without a prescription and ship to the US, although it’ll take a couple of weeks. So far, none of my shipments (4 and counting) have been stopped at the border, but there is a risk. Biogenesis claims that they will reship it at least once if it gets confiscated.

When and how often

 Not more than twice a week in doses of 200mg or less. I have tried taking big doses (400mg at once, and 200mg in the morning followed by 200mg at noon) without any substantial effect. If you want to march for 48 hours then you need to take a bodyweight-appropriate dosage every 18 hours. 
 Moda is for when you need it. It’s not a supplement. Your body will get used to it and then the next “wake-me-up” dosage will just cost you more.

Drug Interactions

 The author discovered firsthand how Omeprazole (A.K.A. Prilosec, an over-the-counter acid control drug) interacts with Modafinil in a bad way. Side effects of the interaction included polyuria (frequent urination), bowel irritation, headaches and abdominal discomfort. Omeprazole can also interact with many other neuroactive drugs because one of its many side-effects is to increase the porosity of the blood-brain barrier. If you are taking Omeprazole then do not take Modafinil, adrafinil or armodafinil. You will be too busy going to the bathroom to enjoy the effect.

Nicotine

 Windows and Linux were written by geeks chugging Pepsi and Mountain Dew, but the Saturn V and the Lunar Lander were designed by engineers puffing on cigarettes. Nicotine is a stimulant that can increase concentration. To insects it’s a poison (the tobacco plant produced it because it killed herbivorous bugs). It can be absorbed through the lungs by smoking tobacco or it can be absorbed through the skin by chewing nicotine gum (most of the nicotine is absorbed through the cheeks and tongue, just as with chewing tobacco) or by wearing a nicotine patch.
 The effects of smoking on your health are well discussed outside of this article, so I’ll focus on its mental effects: Nicotine can cross the blood-brain barrier very easily—about seven seconds from the first puff—and binds to nicotinic acetylcholine receptors on nerve cells. One consequence of this is the increase of dopamine in the brain that brings about a sensation called a “buzz”. It induces the liver into releasing glucose, providing a sense of increased energy, and it stimulates the adrenal gland into producing epinephrine (adrenaline). Then there is the major metabolite of nicotine called cotinine, which is being investigated under the speculation that it has an effect on cognition, too.
 Acetylcholine is the neurotransmitter that activates skeletal muscle cells, making them flex. But because of a single amino-acid difference between brain-cell acetylcholine receptors and muscle-cell receptors, nicotine will activate brain cells without activating muscle cells. That’s a difference between life and death, for if it did activate muscle-cell acetylcholine receptors then nicotine would kill with a mechanism similar to the way nerve gas works. Now you know how tobacco plants deploy their own insecticide: insects don’t have this difference, and the nicotine in tobacco plants kills them.
 With cigarettes you’ll have a choice of regular or mentholated. The addition of menthol increases the half-life of nicotine in the bloodstream because it inhibits the oxidization and glucose breakdown of the drug by the enzyme CYP 2B6, similar to the way the components of grapefruit juice inhibit CYP 3A4 and extend the half-life of modafinil.
 Besides cigarettes there are now chewing gums, patches, and battery-powered false cigarettes that deliver nicotine via steam, but these are not like a “Get Out Of Cancer Free” card. 
 My experience with cigarettes is that they do not contribute much towards mental powers, not enough to justify their use. I entertained the thought that the “buzz” could be beneficial for rare—once-a-year problems that require intense concentration to crack—but there doesn’t seem to be any advantage over a good night’s sleep followed by a fresh cup of coffee.

Where to get it

 Tobacconists, drugstores, supermarkets.

When and how often

 In general “never” is how often because of its addictiveness, additives, and nature as a carcinogen. Outside of that, nicotine’s value as a stimulant appears to work best when you are working on a difficult problem that matters. This is strictly Your Judgement, Your Risk.

Desmopressin

Other Cognitive Enhancers

 These drugs can also function as cognitive boosters, but have not been tried by the author.

Adderall and Ritalin

 Both are amphetamine stimulants—and Schedule II controlled drugs—that are prescribed for Attention Deficit and Hyperactivity Disorder (ADHD) in children and adults. It also has extensive use off-label as “focus in a pill”, the “study drug”, or a drug that makes it easier to concentrate and stay awake. 

 For nootropic use by students looking to ace their exams, it should be taken 30 minutes before a study session, and the study session should replicate the kind of environment they expect to be in when they take their exam. IE: At the same time of day, similar lighting conditions, sitting with the same posture, and with no distractions. On the day of the exam the student would need to take another dose of Adderall 30 minutes before the exam starts in order to settle into the same mood and state of attention they were in when studying. It’s the matching of mood and environment that makes it easier to recall the material.

 Addrall, being a stimulant, can cause heart attacks in people with a history of heart disease and seizures in people who have a history of seizures—sufficient that one should think twice about taking it recreationally, even if you don’t think you have a medical problem. There are also a large number of adverse drug interactions with Adderall, particularly antidepressants.
 If that wasn’t enough, some of the effects of long-term use of Adderall are coming to bear. Scientific American has published an article citing evidence of cognitive decline. Heavy users of the stimulant who suddenly discontinue taking it will also find themselves “falling off a cliff” into extreme fatigue and depression.
 This turns on the tape-recorder in your brain. It’s also the most dangerous nootropic in the list because it interferes with homeostasis. Desmopressin is a synthetic analogue to the natural hormone vasopressin, which not only acts as a vasoconstrictor (shrinking the diameter of blood vessels) but also affects the hypothalamus and vastly improves memory formation. For nootropic use you need the nasal spray as to absorb the drug through the nasal membrane closest to the brain. Its effect is almost instantaneous and its users tend to take it immediately before lectures, conferences, and study periods. The effect can last for several hours and tends to leave one with a stronger recollection of the material studied while under its influence.
 Do not take Desmopressin if you have high blood pressure. You may recall at the beginning of this article that I said these drugs would be listed in order of increasing risk. We’re now at the end of the list and—if you pardon my language—you do not want to fuck with Desmo. I even placed it after smoking since it can kill you much faster and with fewer doses. Here’s the deal:
  • A vasoconstrictor will increase your blood pressure
  • It will make your kidneys retain water, so another effect of Desmopressin is to reduce urine production (Desmopressin is commonly prescribed to prevent bedwetting)
  • Part of your body’s homeostasis mechanism is to regulate blood water content by removing it—via the kidneys—into the bladder
  • Having too much water in your bloodstream can lead to electrolyte imbalance, and in severe cases this is called hyponatremia, or “water poisoning”
  • Hyponatremia is difficult to treat. If your doctors cannot control the rebalancing of your electrolytes, you may experience central pontine myelinolysis—nerve damage to the central pons area of the brain stem, which regulates autonomic functions such as breathing. Heart failure is also possible.
 Use Desmopressin irresponsibly and you’ll enjoy the rest of your life in an iron lung, unless you die before they can hook you up to one. If you remember the “Hold your wee for a Wii” contest held by a radio station, where a woman held her bladder for so long she died, know that she died of hyponatremia—the same malady that can be caused by the wrongful use of this drug.
 If you were to take Desmopressin then you must avoid heavy exercise and the excessive consumption of liquids for at least 6 hours afterwards. Do not drink sport drinks such as Gatorade or Powerade. Drink only when thirsty and only until you’re no longer thirsty. 
 Desmopressin costs about $25 for a nasal spray bottle containing enough liquid for 6-7 doses, and is available over the Internet without a prescription from suppliers such as Biogenesis Antiaging. For nootropic use, hold your breath while you administer about 2 squirts per nostril, then breathe in through your nose. You may experience a runny nose and sneezing, but this is normal and will go away. The author has also experienced a mild buzz immediately after use that diminished after a few minutes. 
 Desmopressin should not be used more than once a week. It isn’t a supplement and it won’t make you smarter. It’s what you would take before you have to study and memorize material that doesn’t lend itself to memorization easily, such as a lecture.
 In many ways, this drug is the opposite of alcohol. Booze makes you pee and forget things, while Desmopressin restricts urine production and makes you remember everything, and the mechanisms for each are strikingly similar. Alcohol is a vasodilator: it makes your blood vessels expand and encourages the kidneys to remove more water from your blood. But you would be a fool—perhaps a dead fool—if you were to mix the both in hopes to get the fuzz of alcohol without the side-effects. 

Where to get it

When and how often

 Immediately before studying or attending a lecture. Never more than once a week. Never before heavy exercise. Never before drinking alcohol or lots of fluids. This is not a nutritional supplement, it is a drug and it’s dangerous.

Are these “Brains in a pill”?

 None of these drugs, nor any other kind of drug, can make you smart on their own. They are just like the protein supplements and amino acids sold to bodybuilders: they can’t make you strong, only exercise can do that, but the idea is that the right nutrition combined with the right exercise will make you stronger than the exercise alone. 
 Taking these drugs and then vegging-out in front of TV will only turn you into a dope who knows a lot about TV. They will only work to make you smarter, or remember more material, or hold your focus longer if you combine them with study and mental exercise. 

The responsible use of “smart drugs”

 Sport drinks, dietary supplements and amino acids are safe and acceptable chemicals used by athletes and fitness enthusiasts every day with no ill effects or moral hazard. They improve health and physique, if simply because humans are animals of a chemical origin with chemistry at the heart of our basic functions. In the above I’ve covered everything that I’ve personally used myself, and all but cigarettes and Desmo should be considered on the same level as what you’ll find in a GNC or Vitamin World store on any street in America.

Experimenting With Nootropics to Increase Mental Capacity, Clarity

These smart drugs, made up of a combination of food substances and purified components of medicinal plants, help to improve brain function.

Nootropics-Post.jpg

Hunters will go to great lengths to gain an edge over their prey. You never know where the margin between success and failure may lie, so you wake up extra early, say a prayer, spray bottled deer piss on your boots, and do whatever else you think might increase your odds. My schedule recently got more demanding thanks to a new baby. With less time to kill and another mouth to feed, I’ve had to step up my game.

Hunting can be physically demanding but, assuming that you’re prepared, it’s mostly mental. Staying sharp is how opportunities are created. I ordered a bottle of nootropic pills, in case it might help.

Nootropic (new-tro-pik) is the term for supplements, also known as smart drugs, that improve brain function. They can be food substances like phenethylamine and L-Theanine, found in chocolate and green tea, respectively. Nootropics also include extracted and purified components of medicinal plants, as well as substances synthesized from chemical precursors, such as piracetam, the world’s first official nootropic (piracetam was created in 1964 in Belgium by a team of scientists whose leader, Dr. Corneliu E. Giurgea, coined the term). Since then piracetam has been widely used as a cognitive enhancer and to treat neurological diseases like Alzheimer’s.

Some people consider stimulants to be a form of nootropic, while others distinguish them from the likes of caffeine, and Adderall — of which there’s currently a nationwide shortage. Most legal users of this attention-deficit hyperactivity disorder (ADHD) drug are children; it’s prescribed sparingly in adults for fear of abuse. The FDA caused the shortage by halting delivery to drug manufacturers of the drug’s active ingredient, an amphetamine, for months, arguing that enough Adderall had already been produced to satisfy all legal demand. The agency argued that abusers of Adderall are responsible for the shortage. That’s a group that includes students and professionals using Adderall to help boost productivity during stressful times.

My schedule recently got more demanding thanks to a new baby. With less time to kill and another mouth to feed, I’ve had to step up my game.

I chose the nootropic pills I ordered, a formulation called Alpha Brain, mainly because their ingredients are extracted rather than synthesized. I swallowed some the day they arrived, and waited to become mentally sharp. I wanted fireworks bright enough to eliminate all doubt about whether they worked.

Nothing happened until I was falling asleep, when I became distinctly aware that I was falling asleep. I monitored the entire process and remained lucid, with a measure of free will, as I dreamed, and woke up surprisingly refreshed. While I remembered many of my dreams, some of which were quite long, I couldn’t recall how my underpants ended up around my ankles.

I bought the pills hoping they might make a difference in the one hunting trip I had time for last season. I was headed for an area so populated with deer that I could legally shoot several. But even when animals are abundant they don’t exactly dive eagerly into your rig. You still have to go get them.

Alpha Brain’s most noticeable impact on hunting was making it easier to wake up early. Since I’m typically not a morning person, this was striking, and helpful. I also felt slightly more organized, and a curious sense of emotional stability. These changes could also be attributed to parenthood, and my determination to do the deed and get home as soon as possible.

For whatever reason, it was a good hunt. I got my allotted four deer, and was able to convince a trophy hunter to give me the body of a monster buck we both knew he wasn’t going to eat.

Back home, I contacted Aubrey Marcus, whose company Onnit Labs produces Alpha Brain. He attributed my lucid dreaming to increased levels of the neurotransmitter acetylcholine, which enhances REM dreaming. Alpha Brain has two ingredients that boost acetylcholine levels: GPC choline, which the body converts to acetylcholine, and Huperzine A, an alkaloid derived from Chinese club moss, also known as Huperzia serrata. “Huperzine A disarms the enzyme that naturally breaks down acetylcholine,” Marcus said. “So while the GPC choline is being converted to acetylcholine, the Huperzine A is keeping it from disappearing. It’s like plugging the drain and turning on the faucet.”

I asked Marcus which nootropic he would want if he were stranded on a desert island. ”I guess it would depend on the challenges I was facing on the island. If staying healthy was the biggest challenge, then I’d choose AC-11,” he said. “If I needed to stay motivated to rebuild the village, I would choose Mucuna [pruriens]. If I was hunting, I’d choose Huperzia serrata, for mental acuity and speed.”

The AC-11 that Marcus mentioned for health is an extract from the Amazon jungle vine una de gato, and has been shown in laboratory and clinical trials to encourage DNA repair. The Mucuna pruriens he named for motivation is a legume that’s a concentrated source of L-Dopa, which the body converts to the neurotransmitter dopamine. The Huperzia serrata Marcus selected for hunting is the same substance that induces lucid dreaming. This seems appropriate. While I felt the Alpha Brain helped my hunting, maybe I was dreaming. Or maybe a dream state of mind is good for hunting.

Clinical psychiatrist Emily Deans has a private practice in Massachusetts and teaches at Harvard Medical School. She told me by phone that, in principle, there’s “probably nothing dangerous” about the occasional course of nootropics for a hunting trip, finals week, or some big project. Beyond that, she suggests considering that it’s possible to build up a tolerance to many neuroactive products if you use them often enough.

She recommends seeking pharmaceutical-grade products if possible, which are more accurate regarding dosage and less likely to be contaminated. In various preparations of the herbal antidepressant St. John’s Wort, for example, dosages of the active ingredients are all over the map, she said.

Deans cautioned that in high-enough doses, acetylcholine affects your autonomic nervous system, influencing your temperature, heart rate, and blood pressure. So increasing the dosages to chase better dreams could be dangerous.

In fact, many nerve gas agents act similarly to Huperzia serrata by blocking the enzyme that breaks down acetylcholine. But research has shown that in smaller doses, Huperzine A, the extract of Huperzia serrata used in nootropics, would likely offer some protection against damage from nerve agents. That the same substance can act as a nerve agent, protect against nerve agents, and give you crazy dreams, underscores how important it is to stay within the recommended doses.

The ingredients used in Alpha Brain are pharmaceutical grade when possible, according to Marcus, who told me via email “There are numerous double-blind studies on all of the ingredients in our product that demonstrate safety in higher doses than we are using, which you can see [online].”

He added: “Many of these studies also demonstrate facets of efficacy. However, until we complete our own clinical trial (six to nine months from now) there will be no clinical evidence on the effectiveness of our own concentration.”

The ingredients in Alpha Brain are available separately, over the counter. So in buying Alpha Brain, or any other commercially available nootropic concoction, you’re paying the brand to do the shopping and mixing for you, like paying a chef to prepare ingredients you could have acquired and cooked yourself.

The number of neuroactive products being studied and brought to market today is unprecedented, and it’s tempting to think some of these might make you a more effective person. Explore carefully. With nootropics, due diligence is in order.

Vitamin C is an essential nutrient required by the body for the development and maintenance of scar tissue, blood vessels, and cartilage. Vitamin C is also necessary for creating ATP, dopamine, peptide hormones, and tyrosine. As a powerful antioxidant, vitamin C helps lessen oxidative stress to the body and is thought to lower cancer risk. The current RDA for vitamin C is 60mg, below is a list of foods high in vitamin C. For those looking to consume extremely high levels of vitamin C
