(We already saw that too much iodine could poison both adults and children, and of course too little does not help much - iodine would seem to follow a U-curve like most supplements.) The listed doses at iherb.com often are ridiculously large: 10-50mg! These are doses that seems to actually be dangerous for long-term consumption, and I believe these are doses that are designed to completely suffocate the thyroid gland and prevent it from absorbing any more iodine - which is useful as a short-term radioactive fallout prophylactic, but quite useless from a supplementation standpoint. Fortunately, there are available doses at Fitzgerald 2012’s exact dose, which is roughly the daily RDA: 0.15mg. Even the contrarian materials seem to focus on a modest doubling or tripling of the existing RDA, so the range seems relatively narrow. I’m fairly confident I won’t overshoot if I go with 0.15-1mg, so let’s call this 90%.
Dr Hart talked through food intolerance tests that are available through a number of well known companies, including York Test for whom she is Scientific Director. A possible strategy could be to use such testing to identify intolerances, follow an elimination protocol, temporarily removing on foods triggering an IgG response; and then work to improve your gut health to support longer term well-being. Foods that are rich in collagen and its amino acids, like glycine and proline, are great for healing connective tissue, which is what the intestines are made up of. A traditional food, rich in these amino acids, that has made its way into our kitchens again after rediscovering its therapeutic properties is bone broth. Another example of a group of traditional foods that can be used therapeutically in building digestive health, are fermented foods such as kefir, sauerkraut and kimchi. These are abundant in probiotics, which are the ‘good’ bacteria our digestive system needs to help keep a good balance and protect the intestinal barrier from pathogens, toxins and parasites. Once these foods have been introduced on an everyday basis along with eating a healthy nutrient-dense diet and the possible use of supplements to help restore balance, you may be able to reintroduce foods that were previously triggering an IgG response carefully, one at a time, whilst monitoring symptoms.

I decided to try out day-time usage on 2 consecutive days, taking the 100mg at noon or 1 PM. On both days, I thought I did feel more energetic but nothing extraordinary (maybe not even as strong as the nicotine), and I had trouble falling asleep on Halloween, thinking about the meta-ethics essay I had been writing diligently on both days. Not a good use compared to staying up a night.
One item always of interest to me is sleep; a stimulant is no good if it damages my sleep (unless that’s what it is supposed to do, like modafinil) - anecdotes and research suggest that it does. Over the past few days, my Zeo sleep scores continued to look normal. But that was while not taking nicotine much later than 5 PM. In lieu of a different ml measurer to test my theory that my syringe is misleading me, I decide to more directly test nicotine’s effect on sleep by taking 2ml at 10:30 PM, and go to bed at 12:20; I get a decent ZQ of 94 and I fall asleep in 16 minutes, a bit below my weekly average of 19 minutes. The next day, I take 1ml directly before going to sleep at 12:20; the ZQ is 95 and time to sleep is 14 minutes.
The exact moment when science morphed into science fiction was when so-called climate scientists (formerly known as weather forecasters) realised that some people could be conned into believing in man-made global warming and pumping fortunes into university departments to prove it. Now, they're all at it.Come back Arthur C Clarke. Your country needs you now.
I met Alex one evening last summer, at an appealingly scruffy bar in the New England city where he lives. Skinny and bearded, and wearing faded hipster jeans, he looked like the lead singer in an indie band. He was ingratiating and articulate, and smoked cigarettes with an ironic air of defiance. Alex was happy enough to talk about his frequent use of Adderall at Harvard, but he didn't want to see his name in print; he's involved with an internet start-up and worried that potential investors might disapprove of his habit.
The makeup of the brain is about 29% fat, most of which is located in myelin (which itself is 70–80% fat).[8] Specific fatty acid ratios will depend in part on the diet of the animal it is harvested from. The brain is also very high in cholesterol. For example, a single 140 g (5 oz) serving of "pork brains in milk gravy" can contain 3500 mg of cholesterol (1170% of the USRDA).[9]
I largely ignored this since the discussions were of sub-RDA doses, and my experience has usually been that RDAs are a poor benchmark and frequently far too low (consider the RDA for vitamin D). This time, I checked the actual RDA - and was immediately shocked and sure I was looking at a bad reference: there was no way the RDA for potassium was seriously 3700-4700mg or 4-5 grams daily, was there? Just as an American, that implied that I was getting less than half my RDA. (How would I get 4g of potassium in the first place? Eat a dozen bananas a day⸮) I am not a vegetarian, nor is my diet that fantastic: I figured I was getting some potassium from the ~2 fresh tomatoes I was eating daily, but otherwise my diet was not rich in potassium sources. I have no blood tests demonstrating deficiency, but given the figures, I cannot see how I could not be deficient.
Our top recommendation for cognitive energy enhancement is Brainol. This product is formulated from all natural ingredients. Brainol is a product that works internally. This herbal blend contains 19 key ingredients such as Huperzine A, L-Tyrosine, L-Theanine, St. John’s Wort, Phosphatidylserine, Bacopa Monnieri and Guarana, to name but a few. There are no unwanted side effects from these all natural ingredients.
Still, the scientific backing and ingredient sourcing of nootropics on the market varies widely, and even those based in some research won't necessarily immediately, always or ever translate to better grades or an ability to finally crank out that novel. Nor are supplements of any kind risk-free, says Jocelyn Kerl, a pharmacist in Madison, Wisconsin.

Sure, you could certainly swallow too much St. John’s Wort and create the same type of serotonin or neurotransmitter issues you could create with a synthetic smart drug, but it’s far more difficult to harm yourself with a nootropic compared to a synthetic smart drug. Although synthetic, laboratory-designed nootropics do indeed exist, even those are not as harsh on the biology as a smart drug and have a mechanism of action that is a bit more natural. Let’s begin with the more natural nootropics.
Lisa Mosconi has a web and media presence and a book Brain Food: The Surprising Science of Eating for Cognitive Power. She claims, “There is increasing evidence that implementing the lifestyle changes described in this book has the potential to prevent Alzheimer’s from developing and also to help slow down or even halt progression of the disease.” What’s more, “eating for your brain…actually helps you achieve peak performance in every part of your life.”
Most of the most solid fish oil results seem to meliorate the effects of age; in my 20s, I’m not sure they are worth the cost. But I would probably resume fish oil in my 30s or 40s when aging really becomes a concern. So the experiment at most will result in discontinuing for a decade. At $X a year, that’s a net present value of sum $ map (\n -> 70 / (1 + 0.05)^n) [1..10] = $540.5.

Another prescription stimulant medication, modafinil (known by the brand name Provigil), is usually prescribed to patients suffering from narcolepsy and shift-work sleep disorder, but it might turn out to have broader applications. “We have conducted at the University of Cambridge double-blind, placebo-controlled studies in healthy people using modafinil and have found improvements in cognition, including in working memory,” Sahakian says. However, she doesn’t think everyone should start using the drug off-label. “There are no long-term safety and efficacy studies of modafinil in healthy people, and so it is unclear what the risks might be.”

Be patient.  Even though you may notice some improvements right away (sometimes within the first day), you should give your brain supplement at least several months to work.  The positive effects are cumulative, and most people do not max out their brain potential on a supplement until they have used it for at least 90 days.  That is when the really dramatic effects start kicking in!


Microdosing involves ingesting small amounts of psychedelics to induce a very subtle physical and mental effect accompanied by a very noticeable, overall positive, health effect. When you take a microdose of a psychedelic, it is typically referred to as a sub-perceptual dose. A sub-perceptual dose will not have a major impact on your ability to function normally, but the effect will definitely be present in your mood and behavior. The microdose of a particular psychedelic is correlated to the lowest dose that will produce a noticeable effect, which is also known as the threshold dose. Since the goal is not to get a hallucinogenic effect, a microdose can be well below the psychedelics threshold dose. By integrating the correct doses of psychedelics into your weekly routine, you can achieve higher creativity levels, more energy, improved mood, increased focus, and better relational skills. There is a growing body of research that shows microdosing to improve depression, anxiety, PTSD, and emotional imbalance, help with alcohol and tobacco addiction, and decrease ADD and ADHD behaviors.

The greatly increased variance, but only somewhat increased mean, is consistent with nicotine operating on me with an inverted U-curve for dosage/performance (or the Yerkes-Dodson law): on good days, 1mg nicotine is too much and degrades performance (perhaps I am overstimulated and find it hard to focus on something as boring as n-back) while on bad days, nicotine is just right and improves n-back performance.

After we had ordered beers he said: "One of the most impressive features of being a student is how aware you are of a 24-hour work cycle. When you conceive of what you have to do for school, it's not in terms of nine to five but in terms of what you can physically do in a week while still achieving a variety of goals - social, romantic, extracurricular, CV-building, academic."
We did note a significant warning with this product, namely that the caffeine it contains may cause a negative impact, mainly that some users may experience the jitters. Their dosage suggests that one can take up to 6 pills a day, which we felt was too many. These issues made us a little wary of the product, even though they seem to know the right ingredients to include.
Even the best of today’s nootropics only just barely scratch the surface. You might say that we are in the “Nokia 1100” phase of taking nootropics, and as better tools and more data come along, the leading thinkers in the space see a powerful future. For example, they are already beginning to look past biochemistry to the epigenome. Not only is the epigenome the code that runs much of your native biochemistry, we now know that experiences in life can be recorded in your epigenome and then passed onto future generations. There is every reason to believe that you are currently running epigenetic code that you inherited from your great-grandmother’s life experiences. And there is every reason to believe that the epigenome can be hacked – that the nootropics of the future can not only support and enhance our biochemistry, but can permanently change the epigenetic code that drives that biochemistry and that we pass onto our children.

Absorption of nicotine across biological membranes depends on pH. Nicotine is a weak base with a pKa of 8.0 (Fowler, 1954). In its ionized state, such as in acidic environments, nicotine does not rapidly cross membranes…About 80 to 90% of inhaled nicotine is absorbed during smoking as assessed using C14-nicotine (Armitage et al., 1975). The efficacy of absorption of nicotine from environmental smoke in nonsmoking women has been measured to be 60 to 80% (Iwase et al., 1991)…The various formulations of nicotine replacement therapy (NRT), such as nicotine gum, transdermal patch, nasal spray, inhaler, sublingual tablets, and lozenges, are buffered to alkaline pH to facilitate the absorption of nicotine through cell membranes. Absorption of nicotine from all NRTs is slower and the increase in nicotine blood levels more gradual than from smoking (Table 1). This slow increase in blood and especially brain levels results in low abuse liability of NRTs (Henningfield and Keenan, 1993; West et al., 2000). Only nasal spray provides a rapid delivery of nicotine that is closer to the rate of nicotine delivery achieved with smoking (Sutherland et al., 1992; Gourlay and Benowitz, 1997; Guthrie et al., 1999). The absolute dose of nicotine absorbed systemically from nicotine gum is much less than the nicotine content of the gum, in part, because considerable nicotine is swallowed with subsequent first-pass metabolism (Benowitz et al., 1987). Some nicotine is also retained in chewed gum. A portion of the nicotine dose is swallowed and subjected to first-pass metabolism when using other NRTs, inhaler, sublingual tablets, nasal spray, and lozenges (Johansson et al., 1991; Bergstrom et al., 1995; Lunell et al., 1996; Molander and Lunell, 2001; Choi et al., 2003). Bioavailability for these products with absorption mainly through the mucosa of the oral cavity and a considerable swallowed portion is about 50 to 80% (Table 1)…Nicotine is poorly absorbed from the stomach because it is protonated (ionized) in the acidic gastric fluid, but is well absorbed in the small intestine, which has a more alkaline pH and a large surface area. Following the administration of nicotine capsules or nicotine in solution, peak concentrations are reached in about 1 h (Benowitz et al., 1991; Zins et al., 1997; Dempsey et al., 2004). The oral bioavailability of nicotine is about 20 to 45% (Benowitz et al., 1991; Compton et al., 1997; Zins et al., 1997). Oral bioavailability is incomplete because of the hepatic first-pass metabolism. Also the bioavailability after colonic (enema) administration of nicotine (examined as a potential therapy for ulcerative colitis) is low, around 15 to 25%, presumably due to hepatic first-pass metabolism (Zins et al., 1997). Cotinine is much more polar than nicotine, is metabolized more slowly, and undergoes little, if any, first-pass metabolism after oral dosing (Benowitz et al., 1983b; De Schepper et al., 1987; Zevin et al., 1997).

So I eventually got around to ordering another thing of nicotine gum, Habitrol Nicotine Gum, 4mg MINT flavor COATED gum. 96 pieces per box. Gum should be easier to double-blind myself with than nicotine patches - just buy some mint gum. If 4mg is too much, cut the gum in half or whatever. When it arrived, my hopes were borne out: the gum was rectangular and soft, which made it easy to cut into fourths.

A common dose for this combination is 500 milligrams per day of Lion’s Mane, 240 milligrams per day of Ginkgo Biloba, and 100 milligrams twice per day of Bacopa Monnieri. Consider buying each ingredient in bulk to have stock and experiment with. If you are not experiencing positive results after 12 weeks, try adjusting the dosages in small increments. For example, you can start by adjusting Bacopa Monnieri to 150 milligrams twice per day for a couple weeks. Be patient: the end result is worth the trial and error.
This looks interesting: the Noopept effect is positive for all the dose levels, but it looks like a U-curve - low at 10mg, high at 15mg, lower at 20mg, and even lower at 30mg 48mg and 60mg aren’t estimated because they are hit by the missingness problem: the magnesium citrate variable is unavailable for the days the higher doses were taken on, and so their days are omitted and those levels of the factor are not estimated. One way to fix this is to drop magnesium from the model entirely, at the cost of fitting the data much more poorly and losing a lot of R2:
The third category was cognitive control - how effectively you can check yourself in circumstances where the most natural response is the wrong one. A classic test is the Stroop Task, in which people are shown the name of a colour (let's say orange) written in a different colour (let's say purple). They're asked to read the word (which is easy, because our habitual response to a word is to read it) or to name the ink colour (which is harder, because our first impulse is to say "orange"). These studies presented a more mixed picture, but overall they showed some benefit "for most normal healthy subjects" - especially for people who had inherently poorer cognitive control.

The problems with our mental functions begin if the blood flow to the brain cells is disrupted regardless of the reasons. There are countless capillaries in the head, which supply the brain with essential nutrients and oxygen. If the blood doesn’t get to these capillaries, your optimal mental performance is compromised. Here’s a term worth remembering – hypoperfusion. If you’re suffering from hypoperfusion, then this means you are having problems with the blood flow to your brain. Here’s a quick overview of the factors that most commonly cause hypoperfusion:


We reached out to several raw material manufacturers and learned that Phosphatidylserine and Huperzine A are in short supply. We also learned that these ingredients can be pricey, incentivizing many companies to cut corners.  A company has to have the correct ingredients in the correct proportions in order for a brain health formula to be effective. We learned that not just having the two critical ingredients was important – but, also that having the correct supporting ingredients was essential in order to be effective.
On the other hand, Phillips said, Provigil's effects "have attenuated over time. The body is an amazing adjusting machine, and there's no upside that I've been able to see to just taking more." A few years ago Phillips tired of poker and started playing competitive Scrabble. He was good, but not that good. He was older than many of his rivals and he needed to undertake a lot of rote memorisation, which didn't come as easily as it once had. "I stopped short of memorising the entire dictionary, and to be really good you have to get up to eight- and nine-letter words," he told me. "But I did learn every word up to five letters, plus maybe 10,000 seven- and eight-letter words." Provigil, he said, helped with the memorisation process but, "it's not going to make you smarter. It's going to make you better able to use the tools you have for a sustained period."

Adaptogens are also known to participate in regulating homeostasis through helping to beneficially regulate the mechanisms of action associated with the HPA-axis (think back to the importance of proper HPA-axis function which you learned about in my last article on breathwork), including cortisol regulation and nitric oxide regulation. Through these mechanisms, they can protect against chronic inflammation, atherosclerosis, neurodegenerative cognitive impairment, metabolic disorders, cancer and other aging-related diseases. There are plenty of adaptogens with potent benefits, but the ones you learn about in this article are an excellent start to begin building or expanding your stress-adaptation toolbox.

Theanine can also be combined with caffeine as both of them work in synergy to increase memory, reaction time, mental endurance, and memory. The best part about Theanine is that it free of side effects and is easily available in the form of capsules.  A natural option would be to use a good green tea brand which constitutes of tea grown in the shade, because then Theanine would be abundantly present in it.
Capsule Connection sells 1000 00 pills (the largest pills) for $9. I already have a pill machine, so that doesn’t count (a sunk cost). If we sum the grams per day column from the first table, we get 9.75 grams a day. Each 00 pill can take around 0.75 grams, so we need 13 pills. (Creatine is very bulky, alas.) 13 pills per day for 1000 days is 13,000 pills, and 1,000 pills is $9 so we need 13 units and 13 times 9 is $117.
Is a powerful antioxidant that can help you deal with the brain aging process caused by the harmful effects of free radicals. This ingredient does an amazing job of protecting you against muscle catabolism and brain deterioration. In addition, it helps your blood vessels to expand, so all essential ingredients and oxygen are delivered to your brain. The traditional Chinese medicine has been using this herb to boost memory and mental performance.
The low-carb & high-fat diet (includes keto-diet) are not good for you because the brain needs glucose for fuel. It can burn fat. But, the brain’s preferred energy source is glucose. The key is to provide the brain with glucose without raising glucose/serum blood level. You do that by avoiding sugar and eating complex carbohydrates (fresh produce) that convert into glucose.
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.
There are many studies that suggest that Creatine helps in treating cognitive decline in individuals when combined with other therapies. It also helps people suffering from Parkinsons and Huntingtons disease. Though there are minimal side effects associated with creatine, pretty much like any nootropic, it is not  absolutely free of side-effects. An overdose of creatine can lead to gastrointestinal issues, weight gain, stress and anxiety.
One of the other suggested benefits is for boosting serotonin levels; low levels of serotonin are implicated in a number of issues like depression. I’m not yet sure whether tryptophan has helped with motivation or happiness. Trial and error has taught me that it’s a bad idea to take tryptophan in the morning or afternoon, however, even smaller quantities like 0.25g. Like melatonin, the dose-response curve is a U: ~1g is great and induces multiple vivid dreams for me, but ~1.5g leads to an awful night and a headache the next day that was worse, if anything, than melatonin. (One morning I woke up with traces of at least 7 dreams, although I managed to write down only 2. No lucid dreams, though.)
You have probably heard and you already love the term “soul food.” You should know that there’s “brain food” too. Natural supplements are the best way to express your gratitude for all the hard work your brain does for you around the clock. These products aren’t reserved only for the elderly users. On the contrary, if you start using them while you’re still young and sharp, you can ensure the proper protection against all those age-related mental deterioration processes.

Some work has been done on estimating the value of IQ, both as net benefits to the possessor (including all zero-sum or negative-sum aspects) and as net positive externalities to the rest of society. The estimates are substantial: in the thousands of dollars per IQ point. But since increasing IQ post-childhood is almost impossible barring disease or similar deficits, and even increasing childhood IQs is very challenging, much of these estimates are merely correlations or regressions, and the experimental childhood estimates must be weakened considerably for any adult - since so much time and so many opportunities have been lost. A wild guess: $1000 net present value per IQ point. The range for severely deficient children was 10-15 points, so any normal (somewhat deficient) adult gain must be much smaller and consistent with Fitzgerald 2012’s ceiling on possible effect sizes (small).
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.

One thing to notice is that the default case matters a lot. This asymmetry is because you switch decisions in different possible worlds - when you would take Adderall but stop you’re in the world where Adderall doesn’t work, and when you wouldn’t take Adderall but do you’re in the world where Adderall does work (in the perfect information case, at least). One of the ways you can visualize this is that you don’t penalize tests for giving you true negative information, and you reward them for giving you true positive information. (This might be worth a post by itself, and is very Litany of Gendlin.)


Is lifestyle truly important, though? According to Dr. Lisa, "genes load the gun, but lifestyle pulls the trigger." As someone who grew up very aware of my genetic predisposition (diabetes, cardiovascular diseases, breast cancer — you name it and someone in my family has it), I always thought that this weighed heavily on whether or not someone manifests an illness. But, groundbreaking research on epigenetics actually states the contrary. 
Nootrobox co-founder Geoffrey Woo declines a caffeinated drink in favour of a capsule of his newest product when I meet him in a San Francisco coffee shop. The entire industry has a “wild west” aura about it, he tells me, and Nootrobox wants to fix it by pushing for “smarter regulation” so safe and effective drugs that are currently unclassified can be brought into the fold. Predictably, both companies stress the higher goal of pushing forward human cognition. “I am trying to make a smarter, better populace to solve all the problems we have created,” says Nootroo founder Eric Matzner.

The Lynches said that Provigil was a classic example of a related phenomenon: mission creep. In 1998, Cephalon, the pharmaceutical company that manufactures it, received US government approval to market the drug but only for "excessive daytime sleepiness" due to narcolepsy; by 2004, Cephalon had obtained permission to expand the labelling so that it included sleep apnoea and "shift-work sleep disorder". Net sales of Provigil climbed from $196m in 2002 to $988m in 2008.
-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.

In the study, which evaluated the eating habits and mental ability of more than 950 older adults for an average of five years, those adults who ate a serving of leafy green veggies once or twice a day experienced slower mental deterioration than those who ate no vegetables, even when factors like age, education and family history of dementia were factored in.
Kratom (Erowid, Reddit) is a tree leaf from Southeast Asia; it’s addictive to some degree (like caffeine and nicotine), and so it is regulated/banned in Thailand, Malaysia, Myanmar, and Bhutan among others - but not the USA. (One might think that kratom’s common use there indicates how very addictive it must be, except it literally grows on trees so it can’t be too hard to get.) Kratom is not particularly well-studied (and what has been studied is not necessarily relevant - I’m not addicted to any opiates!), and it suffers the usual herbal problem of being an endlessly variable food product and not a specific chemical with the fun risks of perhaps being poisonous, but in my reading it doesn’t seem to be particularly dangerous or have serious side-effects.

Since Racetams result in increased uptake and demand for acetylcholine, stacking choline with this nootropic will further enhance your results. Studies have shown that choline supplementation can improve performance on memory tests as well as social behavior. Choline also plays a key role in the production of phospholipids that are incorporated into brain cell membranes.


(On a side note, I think I understand now why modafinil doesn’t lead to a Beggars in Spain scenario; BiS includes massive IQ and motivation boosts as part of the Sleepless modification. Just adding 8 hours a day doesn’t do the world-changing trick, no more than some researchers living to 90 and others to 60 has lead to the former taking over. If everyone were suddenly granted the ability to never need sleep, many of them would have no idea what to do with the extra 8 or 9 hours and might well be destroyed by the gift; it takes a lot of motivation to make good use of the time, and if one cannot, then it is a curse akin to the stories of immortals who yearn for death - they yearn because life is not a blessing to them, though that is a fact more about them than life.)
Alex's sense of who uses stimulants for so-called "non-medical" purposes is borne out by two dozen or so scientific studies. In 2005 a team led by Sean Esteban McCabe, a professor at the University of Michigan, reported that in the previous year 4.1% of American undergraduates had taken prescription stimulants for off-label use - at one school the figure was 25%, while a 2002 study at a small college found that more than 35% of the students had used prescription stimulants non-medically in the previous year.

Some nootropics users are hopeful that the drugs could be permanently “neuroprotective”—in other words, that the compounds could slow down the neuronal aging process, and help avoid cognitive deterioration later in life. (For what it's worth, most of the users I spoke to said that didn't matter much to them. “I doubt anything I’ve tried has made me smarter in a long-term way,” Baker says. “That’s still science fiction.”)

Adderall, a stimulant composed of mixed amphetamine salts, is commonly prescribed for children and adults who have been given a diagnosis of attention-deficit hyperactivity disorder (ADHD). But in recent years Adderall and Ritalin, another stimulant, have been adopted as cognitive enhancers: drugs that high-functioning, overcommitted people take to become higher-functioning and more overcommitted. (Such use is "off label", meaning that it does not have the approval of either the drug's manufacturer or the FDA, America's Food and Drug Administration.) College campuses have become laboratories for experimentation with neuroenhancement, and Alex was an ingenious experimenter. His brother had received a diagnosis of ADHD, and in his first year as an undergraduate Alex obtained an Adderall prescription for himself by describing to a doctor symptoms that he knew were typical of the disorder. During his college years, Alex took 15mg of Adderall most evenings, usually after dinner, guaranteeing that he would maintain intense focus while losing "any ability to sleep for approximately eight to 10 hours". In his second year, he persuaded the doctor to add a 30mg "extended-release" capsule to his daily regime.
It is at the top of the supplement snake oil list thanks to tons of correlations; for a review, see Luchtman & Song 2013 but some specifics include Teenage Boys Who Eat Fish At Least Once A Week Achieve Higher Intelligence Scores, anti-inflammatory properties (see Fish Oil: What the Prescriber Needs to Know on arthritis), and others - Fish oil can head off first psychotic episodes (study; Seth Roberts commentary), Fish Oil May Fight Breast Cancer, Fatty Fish May Cut Prostate Cancer Risk & Walnuts slow prostate cancer, Benefits of omega-3 fatty acids tally up, Serum Phospholipid Docosahexaenonic Acid Is Associated with Cognitive Functioning during Middle Adulthood endless anecdotes.
Sometimes called smart drugs, brain boosters, or memory-enhancing drugs, the term "nootropics" was coined by scientist Dr. Corneliu E. Giurgea, who developed the compound piracetam as a brain enhancer, according to The Atlantic. The word is derived from the Greek noo, meaning mind, and trope, which means "change" in French. In essence, all nootropics aim to change your mind by enhancing functions like memory or attention.
Before you try nootropics, I suggest you start with the basics: get rid of the things in your diet and life that reduce cognitive performance first. That is easiest. Then, add in energizers like Brain Octane and clean up your diet. Then, go for the herbals and the natural nootropics. Use the pharmaceuticals selectively only after you’ve figured out your basics.
The Neurohacker Collective is a group of scientists, academics, and creatives who, among other things, sell nootropics. One of its premier products is Qualia Original Stack (OS), which has 41 ingredients. The large print says it improves focus, mood, and energy within 30 minutes and “supports long-term brain health.” A 22-dose supply costs $129. Such stacks operate on the idea that synergies among ingredients yield additional benefits.
This is not 100% clear from the data and just blindly using a plausible amount carries the risk of the negative effects, so I intend to run another large experiment. I will reuse the NOW Foods Magnesium Citrate Powder, but this time, I will use longer blocks (to make cumulative overdosing more evident) and try to avoid any doses >150mg of elemental magnesium.

On the nutritional naughty list for years, egg yolks are finally experiencing their well-deserved day in the sun. If you’ve been eating only egg whites, the yolk’s on you. Yolks contain large amounts of choline, which helps in fetal brain development for pregnant women. It also breaks down bethane, a chemical that produces hormones related to happiness. That’s right, eggs can make you happy! (6)
Gibson and Green (2002), talking about a possible link between glucose and cognition, wrote that research in the area …is based on the assumption that, since glucose is the major source of fuel for the brain, alterations in plasma levels of glucose will result in alterations in brain levels of glucose, and thus neuronal function. However, the strength of this notion lies in its common-sense plausibility, not in scientific evidence… (p. 185).
As discussed in my iodine essay (FDA adverse events), iodine is a powerful health intervention as it eliminates cretinism and improves average IQ by a shocking magnitude. If this effect were possible for non-fetuses in general, it would be the best nootropic ever discovered, and so I looked at it very closely. Unfortunately, after going through ~20 experiments looking for ones which intervened with iodine post-birth and took measures of cognitive function, my meta-analysis concludes that: the effect is small and driven mostly by one outlier study. Once you are born, it’s too late. But the results could be wrong, and iodine might be cheap enough to take anyway, or take for non-IQ reasons. (This possibility was further weakened for me by an August 2013 blood test of TSH which put me at 3.71 uIU/ml, comfortably within the reference range of 0.27-4.20.)
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.
Kratom (Erowid, Reddit) is a tree leaf from Southeast Asia; it’s addictive to some degree (like caffeine and nicotine), and so it is regulated/banned in Thailand, Malaysia, Myanmar, and Bhutan among others - but not the USA. (One might think that kratom’s common use there indicates how very addictive it must be, except it literally grows on trees so it can’t be too hard to get.) Kratom is not particularly well-studied (and what has been studied is not necessarily relevant - I’m not addicted to any opiates!), and it suffers the usual herbal problem of being an endlessly variable food product and not a specific chemical with the fun risks of perhaps being poisonous, but in my reading it doesn’t seem to be particularly dangerous or have serious side-effects.

Nootropics. You might have heard of them. The “limitless pill” that keeps Billionaires rich. The ‘smart drugs’ that students are taking to help boost their hyperfocus. The cognitive enhancers that give corporate executives an advantage. All very exciting. But as always, the media are way behind the curve. Yes, for the past few decades, cognitive enhancers were largely sketchy substances that people used to grasp at a short term edge at the expense of their health and wellbeing. But the days of taking prescription pills to pull an all-nighter are so 2010. The better, safer path isn’t with these stimulants but with nootropics. Nootropics consist of supplements and substances which enhance your cognition, in particular when it comes to motivation, creativity, memory, and other executive functions.
