Our current natural brain health formula contains Cordyceps-Sinensis Extract as well as the complete balance of brain health supporting nutrients that work perfectly together to help your body elevate essential acetylcholine levels while increasing the neurological components (neurotransmitters) needed to help you stay alert, focused, mentally driven and calm.
Blueberries and blackberries are at the top of the list of brain-boosting foods because they are exceptionally rich in chemicals called anthocyanins, which are among the most potent antioxidants. "But the real message here is that a diet rich in fruits and vegetables of all kinds does more than keep your heart healthy," says Tufts University neurobiologist James Joseph. It's healthy food for thought.
On 15 March 2014, I disabled light sensor: the complete absence of subjective effects since the first sessions made me wonder if the LED device was even turning on - a little bit of ambient light seems to disable it thanks to the light sensor. So I stuffed the sensor full of putty, verified it was now always-on with the cellphone camera, and began again; this time it seemed to warm up much faster, making me wonder if all the previous sessions’ sense of warmth was simply heat from my hand holding the LEDs
I can test fish oil for mood, since the other claimed benefits like anti-schizophrenia are too hard to test. The medical student trial (Kiecolt-Glaser et al 2011) did not see changes until visit 3, after 3 weeks of supplementation. (Visit 1, 3 weeks, visit 2, supplementation started for 3 weeks, visit 3, supplementation continued 3 weeks, visit 4 etc.) There were no tests in between the test starting week 1 and starting week 3, so I can’t pin it down any further. This suggests randomizing in 2 or 3 week blocks. (For an explanation of blocking, see the footnote in the Zeo page.)
That really says it all: there’s an initial spike in MP, which reads like the promised stimulative effects possibly due to fixing a deficiency (a spike which doesn’t seem to have any counterparts in the previous history of MP), followed by a drastic plunge in the magnesium days but not so much the control days (indicating an acute effect when overloaded with magnesium), a partial recovery during the non-experimental Christmas break, another plunge, and finally recovery after the experiment has ended.

Reason: Besides keeping cells intact, this membrane performs vital functions. These actions include moving nutrients into cells and pumping waste products out of them. Investigators in one study determined that phosphatidyl serine shaved 12 years off the normal expected decline. This result was present in specific aspects of memory performance. Phosphatidyl serine is shown in studies to boost cognitive function. This occurs by increasing communication between brain cells. Those who took 100 mg of phosphatidyl serine three times a day, with meals for 12 weeks scored 30% higher on memory and learning tests.
Broccoli is great source of vitamin K, which is known to enhance cognitive function and improve brainpower. Researchers have reported that because broccoli is high in compounds called glucosinolates, it can slow the breakdown of the neurotransmitter, acetylcholine, which we need for the central nervous system to perform properly and to keep our brains and our memories sharp. Low levels of acetylcholine are associated with Alzheimer's.

There are a variety of substances to get magnesium from. Considerable enthusiasm for the new compound magnesium l-threonate was stirred by 2 small animal rat studies finding that magnesium l-threonate was able to increase magnesium levels in the brain and improve learning/memory tasks. (There are no published human trials as of October 2015, and evidence of publication bias, which I take as evidence against there being large effects in humans.) Animal studies mean very little, of course (see the appendix), but I thought it’d be interesting to try using l-threonate, so I bought the $30 Life Extension Neuro-Mag Magnesium L-Threonate with Calcium and Vitamin D3 (205g), which according to the LEF product page works out to ~60g of Magtein™ magnesium L-threonate and ~4.31g elemental magnesium inasmuch as LEF claims 2000mg of threonate powder provides 144mg elemental magnesium or a 14:1 ratio. (I don’t need the calcium or vitamin D3, but this was the only magnesium l-threonate on Amazon.) Experiment-wise, I’ll probably look at sleep metrics and Mnemosyne performance; I put off designing a blind self-experiment until after trying some.

Taking the tryptophan is fairly difficult. The powder as supplied by Bulk Nutrition is extraordinarily dry and fine; it seems to be positively hydrophobic. The first time I tried to swallow a teaspoon, I nearly coughed it out - the power had seemed to explode in my mouth and go down my lungs. Thenceforth I made sure to have a mouth of water first. After a while, I took a different tack: I mixed in as much Hericium as would fit in the container. The mushroom powder is wetter and chunkier than the tryptophan, and seems to reduce the problem. Combining the mix with chunks of melatonin inside a pill works even better.

In this large population-based cohort, we saw consistent robust associations between cola consumption and low BMD in women. The consistency of pattern across cola types and after adjustment for potential confounding variables, including calcium intake, supports the likelihood that this is not due to displacement of milk or other healthy beverages in the diet. The major differences between cola and other carbonated beverages are caffeine, phosphoric acid, and cola extract. Although caffeine likely contributes to lower BMD, the result also observed for decaffeinated cola, the lack of difference in total caffeine intake across cola intake groups, and the lack of attenuation after adjustment for caffeine content suggest that caffeine does not explain these results. A deleterious effect of phosphoric acid has been proposed (26). Cola beverages contain phosphoric acid, whereas other carbonated soft drinks (with some exceptions) do not.

Still, even if you acknowledge that cosmetic neurology is here to stay, there is something dispiriting about the way the drugs are used - the kind of aspirations they open up, or don't. Jonathan Eisen, an evolutionary biologist at the University of California, Davis, is sceptical of what he mockingly calls "brain doping". During a recent conversation, he spoke about colleagues who take neuroenhancers in order to grind out grant proposals. "It's weird to me that people are taking these drugs to write grants," he said. "I mean, if you came up with some really interesting paper that was spurred by taking some really interesting drug - magic mushrooms or something - that would make more sense to me. In the end you're only as good as the ideas you've come up with."

Pop this pill and improve your memory. Swallow that one and reduce your cognitive decline. We see ads for such products all the time and I suspect they will increase as the baby boomers reach senior citizenhood. The most popular brain boosting supplements are fish oil pills and they are also probably the best studied ones. The results are not encouraging. When all the studies are pooled, we are left with the possibility of a barely significant improvement in recalling lists of words soon after they have been learned, but the effect does not last. Extracts of the ginkgo biloba tree are also popular, and here the prospects are even dimmer. There is no impact on memory, despite claims of increased circulation in the brain. And ginkgo can interfere with the action of anticoagulants and has also been shown to be an animal carcinogen.

-Phosphatidylserine, which occurs naturally in high concentrations in the brain and has been shown to lower stress, cortisol and physical fatigue, improve attention-deficit and forgetfulness and increase mental processing and memory. Research indicates an effective dose of 100 mg three times daily, but anything over that may lead to adverse side effects like insomnia.

Farah told me: "These drugs will definitely help some technically normal people - that is, people who don't meet the diagnostic criteria for ADHD or any kind of cognitive impairment." But, she emphasised, "They will help people in the lower end of the ability range more than in the higher end." One explanation for this phenomenon might be that the more adept you are at a given task, the less room you have to improve. Farah has a hunch that there may be another reason that existing drugs - so far, at least - don't offer as much help to people with greater intellectual abilities. Drugs like Ritalin and Adderall work in part by elevating the amount of dopamine in the brain. Dopamine is something you want just enough of: too little, and you may not be as alert and motivated as you need to be; too much, and you may feel overstimulated. Neuroscientists have discovered that some people have a gene that leads the brain to break down dopamine faster, leaving less of it available; such people are generally a little worse at certain cognitive tasks. People with more available dopamine are generally somewhat better at the same tasks. It makes sense, then, that people with naturally low dopamine would benefit more from an artificial boost.
The evidence? Ritalin is FDA-approved to treat ADHD. It has also been shown to help patients with traumatic brain injury concentrate for longer periods, but does not improve memory in those patients, according to a 2016 meta-analysis of several trials. A study published in 2012 found that low doses of methylphenidate improved cognitive performance, including working memory, in healthy adult volunteers, but high doses impaired cognitive performance and a person’s ability to focus. (Since the brains of teens have been found to be more sensitive to the drug’s effect, it’s possible that methylphenidate in lower doses could have adverse effects on working memory and cognitive functions.)
As professionals and aging baby boomers alike become more interested in enhancing their own brain power (either to achieve more in a workday or to stave off cognitive decline), a huge market has sprung up for nonprescription nootropic supplements. These products don’t convince Sahakian: “As a clinician scientist, I am interested in evidence-based cognitive enhancement,” she says. “Many companies produce supplements, but few, if any, have double-blind, placebo-controlled studies to show that these supplements are cognitive enhancers.” Plus, supplements aren’t regulated by the U.S. Food and Drug Administration (FDA), so consumers don’t have that assurance as to exactly what they are getting. Check out these 15 memory exercises proven to keep your brain sharp.

She provides many examples of observational studies where lower intakes of a certain nutrient were correlated with cognitive impairment. Obviously, if someone is deficient in a vitamin or other nutrient, the deficiency should be corrected. But she doesn’t have any evidence from prospective interventional studies showing that, in practice, altering diet significantly improves cognition for people who are deficient, much less in people who are not deficient.
Much of what she says is standard health advice. Avoid trans fats. Eat fresh vegetables and fruit. Avoid processed foods. Limit red meat consumption. It’s better to get your nutrients from food than from supplement pills. Exercise, get adequate sleep, and avoid stress. Since the brain runs on glucose, she wouldn’t agree with the low-carb diet folks; she says we need adequate sources of glucose in our diet, and recommends complex carbs, paying attention to the glycemic index.
2ml is supposed to translate to 24mg, which is a big dose. I do not believe any of the commercial patches go much past that. I asked Wedrifid, whose notes inspired my initial interest, and he was taking perhaps 2-4mg, and expressed astonishment that I might be taking 24mg. (2mg is in line with what I am told by another person - that 2mg was so much that they actually felt a little sick. On the other hand, in one study, the subjects could not reliably distinguish between 1mg and placebo25.) 24mg is particularly troubling in that I weigh ~68kg, and nicotine poisoning and the nicotine LD50 start, for me, at around 68mg of nicotine. (I reflected that the entire jar could be a useful murder weapon, although nicotine presumably would be caught in an autopsy’s toxicology screen; I later learned nicotine was an infamous weapon in the 1800s before any test was developed. It doesn’t seem used anymore, but there are still fatal accidents due to dissolved nicotine.) The upper end of the range, 10mg/kg or 680mg for me, is calculated based on experienced smokers. Something is wrong here - I can’t see why I would have nicotine tolerance comparable to a hardened smoker, inasmuch as my maximum prior exposure was second-hand smoke once in a blue moon. More likely is that either the syringe is misleading me or the seller NicVape sold me something more dilute than 12mg/ml. (I am sure that it’s not simply plain water; when I mix the drops with regular water, I can feel the propylene glycol burning as it goes down.) I would rather not accuse an established and apparently well-liked supplier of fraud, nor would I like to simply shrug and say I have a mysterious tolerance and must experiment with doses closer to the LD50, so the most likely problem is a problem with the syringe. The next day I altered the procedure to sucking up 8ml, squirting out enough fluid to move the meniscus down to 7ml, and then ejecting the rest back into the container. The result was another mild clean stimulation comparable to the previous 1ml days. The next step is to try a completely different measuring device, which doesn’t change either.
That is, perhaps light of the right wavelength can indeed save the brain some energy by making it easier to generate ATP. Would 15 minutes of LLLT create enough ATP to make any meaningful difference, which could possibly cause the claimed benefits? The problem here is like that of the famous blood-glucose theory of willpower - while the brain does indeed use up more glucose while active, high activity uses up very small quantities of glucose/energy which doesn’t seem like enough to justify a mental mechanism like weak willpower.↩

However, they fell short in several categories. The key issue with their product is that it does not contain DHA Omega 3 and the other essential vitamins and nutrients needed to support the absorption of Huperzine A and Phosphatidylserine. Without having DHA Omega 3 it will not have an essential piece to maximum effectiveness. This means that you would need to take a separate pill of DHA Omega 3 and several other essential vitamins to ensure you are able to reach optimal memory support. They also are still far less effective than our #1 pick’s complete array of the 3 essential brain supporting ingredients and over 30 supporting nutrients, making their product less effective.
In addition to this, privilege also plays an important role in this epidemic. "Not everyone has access to eat healthily", she mentions. In fact, she recalls an anecdote in which a supermarket owner noticed how people living off food stamps rarely use them to buy fruits and vegetables. Curious about this trend, the owner approached someone with food stamps, to which she admitted she didn't buy them because she didn't know the price prior to weighing them and felt ashamed of asking. His solution? Pre-cutting and packaging fruits in order to make them more accessible to those with lower incomes. 
I have lots of problems with procrastination and productivity, most likely due to a mild case of ADHD, and recently it's been getting worse and worse. I was a bit hesitant to take Addium at first because I, like most people, had heard about it as a tool for students to use for cramming and it's results sound a little bit like the results of taking Adderall recreationally, which isn't my cup of tea. I was also hesitant to try it because it's marketing just makes it seem like it's a scam pill, and I unfortunately take quality of advertising rather seriously. I changed my mind (after another particularly trying week at work) after a friend of mine actually recommended it for me and told me that she was having great results from it. In my mind, I figured that if a real person,someone I know and trust, tells me in real life that I should maybe try it...then I may as well give it a shot. I ordered the Addium and as soon as I got it, I started taking it immediately. The Addium actually works. I can't believe it. It's helped a lot with my productivity at work. I'm taking just one tablet per day and it seems to be doing the trick. I think the best part about it is that it's not something that you have to continuously take every day.
My answer is that this is not a lot of research or very good research (not nearly as good as the research on nicotine, eg.), and assuming it’s true, I don’t value long-term memory that much because LTM is something that is easily assisted or replaced (personal archives, and spaced repetition). For me, my problems tend to be more about akrasia and energy and not getting things done, so even if a stimulant comes with a little cost to long-term memory, it’s still useful for me. I’m going continue to use the caffeine. It’s not so bad in conjunction with tea, is very cheap, and I’m already addicted, so why not? Caffeine is extremely cheap, addictive, has minimal effects on health (and may be beneficial, from the various epidemiological associations with tea/coffee/chocolate & longevity), and costs extra to remove from drinks popular regardless of their caffeine content (coffee and tea again). What would be the point of carefully investigating it? Suppose there was conclusive evidence on the topic, the value of this evidence to me would be roughly $0 or since ignorance is bliss, negative money - because unless the negative effects were drastic (which current studies rule out, although tea has other issues like fluoride or metal contents), I would not change anything about my life. Why? I enjoy my tea too much. My usual tea seller doesn’t even have decaffeinated oolong in general, much less various varieties I might want to drink, apparently because de-caffeinating is so expensive it’s not worthwhile. What am I supposed to do, give up my tea and caffeine just to save on the cost of caffeine? Buy de-caffeinating machines (which I couldn’t even find any prices for, googling)? This also holds true for people who drink coffee or caffeinated soda. (As opposed to a drug like modafinil which is expensive, and so the value of a definitive answer is substantial and would justify some more extensive calculating of cost-benefit.)

Also known as Arcalion or Bisbuthiamine and Enerion, Sulbutiamine is a compound of the Sulphur group and is an analogue to vitamin B1, which  is known to pass the blood-brain barrier very easily. Sulbutiamine is found to circulate faster than Thiamine from blood to brain. It is recommended for patients suffering from mental fatigue caused due to emotional and psychological stress. The best part about this compound is that it does not have most of the common side effects linked with a few nootropics.
Methylfolate and methyl B12 work together to control methylation reactions that repair your DNA and regenerate brain cells.[11] The methylated forms are particularly important brain food — you have about three times as much methylfolate in your cerebrospinal fluid (the fluid around your brain and spine) as you do in your blood,[12] where it’s working tirelessly to maintain your nerve connections and repair DNA mutations.[13] Folate and B12 are particularly important for brain anti-aging.[14]
I find this very troubling. The magnesium supplementation was harmful enough to do a lot of cumulative damage over the months involved (I could have done a lot of writing September 2013 - June 2014), but not so blatantly harmful enough as to be noticeable without a randomized blind self-experiment or at least systematic data collection - neither of which are common among people who would be supplementing magnesium I would much prefer it if my magnesium overdose had come with visible harm (such as waking up in the middle of the night after a nightmare soaked in sweat), since then I’d know quickly and surely, as would anyone else taking magnesium. But the harm I observed in my data? For all I know, that could be affecting every user of magnesium supplements! How would we know otherwise?
Do you start your day with a cup (or two, or three) of coffee? It tastes delicious, but it’s also jump-starting your brain because of its caffeine content. Caffeine is definitely a nootropic substance—it’s a mild stimulant that can alleviate fatigue and improve concentration, according to the Mayo Clinic. Current research shows that coffee drinkers don’t suffer any ill effects from drinking up to about four cups of coffee per day. Caffeine is also found in tea, soda, and energy drinks. Not too surprisingly, it’s also in many of the nootropic supplements that are being marketed to people looking for a mental boost. Take a look at these 7 genius brain boosters to try in the morning.
Omega-3 fatty acids—DHA in particular—contribute to a healthy brain. “The brain’s membranes use these fats to improve cellular structure and brain signaling, which translates into better cognitive function,” says Vasanti Malik, ScD, a research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. DHA also quells chronic inflammation that can harm brain cells and lead to cognitive decline.
I noticed what may have been an effect on my dual n-back scores; the difference is not large (▃▆▃▃▂▂▂▂▄▅▂▄▂▃▅▃▄ vs ▃▄▂▂▃▅▂▂▄▁▄▃▅▂▃▂▄▂▁▇▃▂▂▄▄▃▃▂▃▂▂▂▃▄▄▃▆▄▄▂▃▄▃▁▂▂▂▃▂▄▂▁▁▂▄▁▃▂▄) and appears mostly in the averages - Toomim’s quick two-sample t-test gave p=0.23, although a another analysis gives p=0.138112. One issue with this before-after quasi-experiment is that one would expect my scores to slowly rise over time and hence a fish oil after would yield a score increase - the 3.2 point difference could be attributable to that, placebo effect, or random variation etc. But an accidentally noticed effect (d=0.28) is a promising start. An experiment may be worth doing given that fish oil does cost a fair bit each year: randomized blocks permitting an fish-oil-then-placebo comparison would take care of the first issue, and then blinding (olive oil capsules versus fish oil capsules?) would take care of the placebo worry.

The NIDA research study focused on 10 healthy male participants. The men were subjected to two rounds of PET brain scans after consuming either Provigil (200 mg or 400 mg) or a placebo. The scans demonstrated that the Provigil users had an increase in the amount of dopamine in the brain. Dopamine is a key neurological messenger in the brain’s reward system. Cocaine and methamphetamine have a similar effect on the brain, but they are more potent and faster-acting than Provigil. As cocaine and amphetamines are addiction-forming, the reasoning here is that Provigil may also be addictive.
Discussions of PEA mention that it’s almost useless without a MAOI to pave the way; hence, when I decided to get deprenyl and noticed that deprenyl is a MAOI, I decided to also give PEA a second chance in conjunction with deprenyl. Unfortunately, in part due to my own shenanigans, Nubrain canceled the deprenyl order and so I have 20g of PEA sitting around. Well, it’ll keep until such time as I do get a MAOI.
These little chemicals prompt the immune system to kick in and fight back against the stress through inflammation, as though stress is an infection. While inflammation helps protect us against illnesses and repairs the body when you do something like cut yourself, chronic inflammation is a different animal. It’s been linked to autoimmune diseases like multiple sclerosis, anxiety, high blood pressure and more. (2)

The most common front-line of treatment for ADHD is medication and cognitive behavioural therapy (CBT). Prescriptions for ADHD drugs such as Ritalin, have doubled to 922,000 a year in the last decade, and whilst it offers symptom management for many, it has also been found to have significant negative side effects such as weight loss, liver toxicity, and suicidal thoughts, and in the short term may suppress pubertal growth. The aetiology of ADHD is multifactorial, meaning that there are varying influencing factors that drive the symptoms. This is perhaps why this condition has been hard to study and find effective treatment for.
Wild salmon. Deep-water fish, such as salmon, are rich in omega-3 essential fatty acids, which are essential for brain function, says Kulze. Both she and Pratt recommend wild salmon for its "cleanliness" and the fact that it is in plentiful supply. Omega-3s also contain anti-inflammatory substances. Other oily fish that provide the benefits of omega-3s are sardines and herring, says Kulze; she recommends a 4-ounce serving, two to three times a week.
Manually mixing powders is too annoying, and pre-mixed pills are expensive in bulk. So if I’m not actively experimenting with something, and not yet rich, the best thing is to make my own pills, and if I’m making my own pills, I might as well make a custom formulation using the ones I’ve found personally effective. And since making pills is tedious, I want to not have to do it again for years. 3 years seems like a good interval - 1095 days. Since one is often busy and mayn’t take that day’s pills (there are enough ingredients it has to be multiple pills), it’s safe to round it down to a nice even 1000 days. What sort of hypothetical stack could I make? What do the prices come out to be, and what might we omit in the interests of protecting our pocketbook?

Besides Adderall, I also purchased on Silk Road 5x250mg pills of armodafinil. The price was extremely reasonable, 1.5btc or roughly $23 at that day’s exchange rate; I attribute the low price to the seller being new and needing feedback, and offering a discount to induce buyers to take a risk on him. (Buyers bear a large risk on Silk Road since sellers can easily physically anonymize themselves from their shipment, but a buyer can be found just by following the package.) Because of the longer active-time, I resolved to test the armodafinil not during the day, but with an all-nighter.
Dr. Mosconi: I love apples. When I’m at the office though, I’ll bring homemade trail mix [made with] higher quality dried fruit, nuts and seeds. [It's] packed with brain-essential nutrients that come from goji berries, Brazil nuts, walnuts, cacao nibs, pistachios, hemp hearts and  more. Plus, I drink plenty of rose water throughout the day, which is very anti-inflammatory.

Gamma-aminobutyric acid, also known as GABA, naturally produced in the brain from glutamate, is a neurotransmitter that helps in the communication between the nervous system and brain. The main function of this Nootropic is to reduce the unnecessary activity of the nerve cells and helps calm the brain. . Thus it helps improve various conditions, like stress, anxiety and depression by decreasing the beta brain waves and increasing the alpha brain waves.  As a result, cognitive abilities like memory power, attention, and alertness also improve. GABA helps drug addicts recover from addiction by  normalizing the brain’s GABA receptors which reduce anxiety and craving levels in the absence of addictive substances.
The evidence? A 2012 study in Greece found it can boost cognitive function in adults with mild cognitive impairment (MCI), a type of disorder marked by forgetfulness and problems with language, judgement, or planning that are more severe than average “senior moments,” but are not serious enough to be diagnosed as dementia. In some people, MCI will progress into dementia.
Taurine (Examine.com) was another gamble on my part, based mostly on its inclusion in energy drinks. I didn’t do as much research as I should have: it came as a shock to me when I read in Wikipedia that taurine has been shown to prevent oxidative stress induced by exercise and was an antioxidant - oxidative stress is a key part of how exercise creates health benefits and antioxidants inhibit those benefits.
Took pill 1:27 PM. At 2 my hunger gets the best of me (despite my usual tea drinking and caffeine+piracetam pills) and I eat a large lunch. This makes me suspicious it was placebo - on the previous days I had noted a considerable appetite-suppressant effect. 5:25 PM: I don’t feel unusually tired, but nothing special about my productivity. 8 PM; no longer so sure. Read and excerpted a fair bit of research I had been putting off since the morning. After putting away all the laundry at 10, still feeling active, I check. It was Adderall. I can’t claim this one either way. By 9 or 10 I had begun to wonder whether it was really Adderall, but I didn’t feel confident saying it was; my feeling could be fairly described as 50%.

Pomegranate juice. Pomegranate juice (you can eat the fruit itself but with its many tiny seeds, it's not nearly as convenient) offers potent antioxidant benefits, says Kulze, which protect the brain from the damage of free radicals. "Probably no part of the body is more sensitive to the damage from free radicals as the brain," says board-certified neurologist David Perlmutter, MD, author of The Better Brain Book. Citrus fruits and colorful vegetables are also high on Perlmutter's list of "brainy" foods because of their antioxidant properties -- "the more colorful the better," he says. Because pomegranate juice has added sugar (to counteract its natural tartness), you don't want to go overboard, says Kulze; she recommends approximately 2 ounces a day, diluted with spring water or seltzer.
Choline is very important for cognitive function because it is a precursor to Acteylcholine. Your body needs enough choline to convert into Acteylcholine to keep your brain healthy. For this reason, choline supplements are often considered great nootropics, even by themselves. CDP-Choline and Alpha GPC are the best sources for supplemental Choline.
Recently I spoke on the phone with Barbara Sahakian, a clinical neuropsychologist at Cambridge University and the co-author of a 2007 article in Nature entitled "Professor's Little Helper". Sahakian, who also consults for several pharmaceutical companies, and her co-author, Sharon Morein-Zamir, reported that a number of their colleagues were using prescription drugs like Adderall and Provigil. Because the drugs are easy to buy online, they wrote, it would be difficult to stop their spread: "The drive for self-enhancement of cognition is likely to be as strong if not stronger than in the realms of 'enhancement' of beauty and sexual function." (In places like Cambridge, at least.)
Siberian Ginseng: Also known as Eleutherococcus senticosus, this herb is native to Russia, China, Japan and other areas of east Asia.  There is not a lot of western research backing Siberian Ginseng as a nootropic yet, but the supplement has been used in traditional medicine in the Far East for quite some time.  Plenty of anecdotal evidence backs it up as an excellent memory and attention enhancer.
Potassium citrate powder is neither expensive nor cheap: I purchased 453g for $21. The powder is crystalline white, dissolves instantly in water, and largely tasteless (sort of saline & slightly unpleasant). The powder is 37% potassium by weight (the formula is C6H5K3O7) so 453g is actually 167g of potassium, so 80-160 days’ worth depending on dose.

A big part is that we are finally starting to apply complex systems science to psycho-neuro-pharmacology and a nootropic approach. The neural system is awesomely complex and old-fashioned reductionist science has a really hard time with complexity. Big companies spends hundreds of millions of dollars trying to separate the effects of just a single molecule from placebo – and nootropics invariably show up as “stacks” of many different ingredients (ours, Qualia , currently has 42 separate synergistic nootropics ingredients from alpha GPC to bacopa monnieri and L-theanine). That kind of complex, multi pathway input requires a different methodology to understand well that goes beyond simply what’s put in capsules.
