We recently held an informative event in London with Dr Gill Hart, a biochemist and expert in the field of food intolerances and their global effect on health and we wanted to share some of the highlights of what Dr Hart covered. Based on some of her recent research (1), the talk offered some interesting insights into how food intolerances may have a role to play in our mental health. It honed in on the differences between food allergies and food intolerances within our immune system; some of the ways that our immune system, gut and brain are believed to influence each other, and how food intolerances, therefore, can play a role in mental health symptoms. She also spoke about how to go about testing and managing these intolerances through elimination diet strategies.
Adderall is a mix of 4 amphetamine salts (FDA adverse events), and not much better than the others (but perhaps less addictive); as such, like caffeine or methamphetamine, it is not strictly a nootropic but a cognitive enhancer and can be tricky to use right (for how one should use stimulants, see How To Take Ritalin Correctly). I ordered 10x10mg Adderall IR off Silk Road (Wikipedia). On the 4th day after confirmation from seller, the package arrived. It was a harmless looking little padded mailer. Adderall as promised: 10 blue pills with markings, in a double ziplock baggy (reasonable, it’s not cocaine or anything). They matched pretty much exactly the descriptions of the generic I had found online. (Surprisingly, apparently both the brand name and the generic are manufactured by the same pharmacorp.)

But it's not the mind-expanding 1960s any more. Every era, it seems, has its own defining drug. Neuroenhancers are perfectly suited to the anxiety of white-collar competition in a floundering economy. And they have a synergistic relationship with our multiplying digital technologies: the more gadgets we own, the more distracted we become and the more we need help in order to focus. The experience that neuroenhancement offers is not, for the most part, about opening the doors of perception, or about breaking the bonds of the self, or about experiencing a surge of genius. It's about squeezing out an extra few hours to finish those sales figures when you'd really rather collapse into bed; getting a B instead of a B-minus on the final exam in a lecture class where you spent half your time texting; cramming for the GREs (postgraduate entrance exams) at night, because the information-industry job you got after college turned out to be deadening. Neuroenhancers don't offer freedom. Rather, they facilitate a pinched, unromantic, grindingly efficient form of productivity.
The above are all reasons to expect that even if I do excellent single-subject design self-experiments, there will still be the old problem of internal validity versus external validity: an experiment may be wrong or erroneous or unlucky in some way (lack of internal validity) or be right but not matter to anyone else (lack of external validity). For example, alcohol makes me sad & depressed; I could run the perfect blind randomized experiment for hundreds of trials and be extremely sure that alcohol makes me less happy, but would that prove that alcohol makes everyone sad or unhappy? Of course not, and as far as I know, for a lot of people alcohol has the opposite effect. So my hypothetical alcohol experiment might have tremendous internal validity (it does prove that I am sadder after inebriating), and zero external validity (someone who has never tried alcohol learns nothing about whether they will be depressed after imbibing). Keep this in mind if you are minded to take the experiments too seriously.
For this batch, I tried out NOW Foods Magnesium Citrate Powder ($7 for 227g); the powder was still a bit sticky but much easier to work with than the Solgar pills, and the 227g made 249 gel capsule pills. The package estimates 119 serving of 315mg elemental magnesium, so a ratio of 0.315g magnesium for 1.9g magnesium citrate, implying that each gel cap pill then contains 0.152g magnesium (\frac{(119\times315)}{249}=150) and since I want a total dose of 0.8g, I need 5 of the gel cap pills a day or 35 per block.
Noopept is a Russian stimulant sometimes suggested for nootropics use as it may be more effective than piracetam or other -racetams, and its smaller doses make it more convenient & possibly safer. Following up on a pilot study, I ran a well-powered blind randomized self-experiment between September 2013 and August 2014 using doses of 12-60mg Noopept & pairs of 3-day blocks to investigate the impact of Noopept on self-ratings of daily functioning in addition to my existing supplementation regimen involving small-to-moderate doses of piracetam. A linear regression, which included other concurrent experiments as covariates & used multiple imputation for missing data, indicates a small benefit to the lower dose levels and harm from the highest 60mg dose level, but no dose nor Noopept as a whole was statistically-significant. It seems Noopept’s effects are too subtle to easily notice if they exist, but if one uses it, one should probably avoid 60mg+.

Intrigued by old scientific results & many positive anecdotes since, I experimented with microdosing LSD - taking doses ~10μg, far below the level at which it causes its famous effects. At this level, the anecdotes claim the usual broad spectrum of positive effects on mood, depression, ability to do work, etc. After researching the matter a bit, I discovered that as far as I could tell, since the original experiment in the 1960s, no one had ever done a blind or even a randomized self-experiment on it.

It’s a frosty Monday evening in March, but in the back of Idea Coffee, a dingy café near the Empire State Building, things are heating up. A group huddles around a small black box—the $160 ApeX Type A brain stimulator, with its retro-looking meter and dial and two electrodes. It’s supposed to bolster learning by delivering a mild electric current to the brain. The guy who’s been experimenting with it for a week notes that the only thing he’s noticed so far is a metallic taste in his mouth.


The realm of natural nootropics is also accompanied by a family of synthetic nootropics called racetams, most notably piracetam and aniracetam. Piracetam is known to directly enhance learning, memory and attention and, with no observed adverse side effects, can restore cognitive performance in patients who have suffered cranial trauma, inflammation, strokes and ischemic complications following coronary bypass surgery. It can also improve symptoms of delirium and reduce depression and anxiety. In adults, the standard dose of piracetam ranges from 1,200 to 4,800 mg, often broken up into three smaller doses throughout the day. Aniracetam has been shown to concentration-dependently counteract cell death induced by excitotoxicity caused by glutamate, resulting in an overall neuroprotective effect. While you may not be shoveling mouthfuls of glutamate down your hatch or eating cartonsful of MSG-containing Chinese food each night, the same mechanism of action can help protect your brain from excitotoxicity or inflammation caused by other central nervous system irritants, such as toxins, chemicals, herbicides, pesticides, rancid oils, etc. Effective doses of aniracetam range from a single 400 mg dose to two doses per day between 500 and 750 mg, taken with meals.
12:18 PM. (There are/were just 2 Adderall left now.) I manage to spend almost the entire afternoon single-mindedly concentrating on transcribing two parts of a 1996 Toshio Okada interview (it was very long, and the formatting more challenging than expected), which is strong evidence for Adderall, although I did feel fairly hungry while doing it. I don’t go to bed until midnight and & sleep very poorly - despite taking triple my usual melatonin! Inasmuch as I’m already fairly sure that Adderall damages my sleep, this makes me even more confident (>80%). When I grumpily crawl out of bed and check: it’s Adderall. (One Adderall left.)

If you want to try a nootropic in supplement form, check the label to weed out products you may be allergic to and vet the company as best you can by scouring its website and research basis, and talking to other customers, Kerl recommends. "Find one that isn't just giving you some temporary mental boost or some quick fix – that’s not what a nootropic is intended to do," Cyr says.
Powders are good for experimenting with (easy to vary doses and mix), but not so good for regular taking. I use OO gel capsules with a Capsule Machine: it’s hard to beat $20, it works, it’s not that messy after practice, and it’s not too bad to do 100 pills. However, I once did 3kg of piracetam + my other powders, and doing that nearly burned me out on ever using capsules again. If you’re going to do that much, something more automated is a serious question! (What actually wound up infuriating me the most was when capsules would stick in either the bottom or top try - requiring you to very gingerly pull and twist them out, lest the two halves slip and spill powder - or when the two halves wouldn’t lock and you had to join them by hand. In contrast: loading the gel caps could be done automatically without looking, after some experience.)

To thwart the rise of non-prescription nootropics, opponents may rally for increased regulation; however, at present, there is insufficient research available to support that non-prescription nootropics pose a danger to public health. Prescription nootropics, such as Ritalin, are already regulated. Further, these drugs have a proven beneficial treatment purpose for intended users.
the rise of IP scofflaw countries which enable the manufacture of known drugs: India does not respect the modafinil patents, enabling the cheap generics we all use, and Chinese piracetam manufacturers don’t give a damn about the FDA’s chilling-effect moves in the US. If there were no Indian or Chinese manufacturers, where would we get our modafinil? Buy them from pharmacies at $10 a pill or worse? It might be worthwhile, but think of the chilling effect on new users.

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.
Microdosing with LSD: LSD (lysergic acid diethylamide) is derived from a chemical in rye fungus. It was originally synthesized in 1938 to aid in childbirth and is widely known for its powerful hallucinogenic effects, but less well known for what I personally use it for: inducing intense sparks of creativity when a merging of the left and right brain hemispheres is the desired goal, such as a day on which I need to do a great deal of creative writing or copywriting. It also works quite well for keeping you “chugging along” on a sleep deprived or jet-lagged day. Similar to psilocybin, LSD affects serotonin levels in the body. By deactivating serotonin mechanisms, brain levels of serotonin are dramatically increased after a dose of LSD, which also causes a “feel good” dopamine release. It is thought that LSD may reduce the blood flow to the control centers of the brain, which weaken their activity, allowing for a heightened brain connection. This enhancement in brain connectivity is most likely why users experience increased creativity and unique thought patterns. Therapeutic effects of LSD include treating addiction, depression, anxiety, obsessive-compulsive disorder, cluster headaches, end-of-life anxiety, resistant behavior change, and increase reaction time, concentration, balance, mood, and pain perception (See additional studies here, here, here, here, here, here, here and here). A typical microdose of LSD is between 5 and 20 micrograms. My own approach for using LSD is quite simple and is called the “volumetric dosing” method. I purchase a blotter paper of LSD or P-LSD, then cut out 100 micrograms with scissors and drop one square tab into a 10-milliliter dropper bottle of vodka. I then know that a single drop of the liquid contains a neat 10 micrograms of LSD, and don’t risk the inaccurate dosing so notoriously associated with simply cutting out and placing the blotter paper into the mouth. Interestingly, I’ve found that if you take slightly too much LSD, a small dose of CBD (e.g. 10-20 milligrams) seems to knock the edge off.
…The Fate of Nicotine in the Body also describes Battelle’s animal work on nicotine absorption. Using C14-labeled nicotine in rabbits, the Battelle scientists compared gastric absorption with pulmonary absorption. Gastric absorption was slow, and first pass removal of nicotine by the liver (which transforms nicotine into inactive metabolites) was demonstrated following gastric administration, with consequently low systemic nicotine levels. In contrast, absorption from the lungs was rapid and led to widespread distribution. These results show that nicotine absorbed from the stomach is largely metabolized by the liver before it has a chance to get to the brain. That is why tobacco products have to be puffed, smoked or sucked on, or absorbed directly into the bloodstream (i.e., via a nicotine patch). A nicotine pill would not work because the nicotine would be inactivated before it reached the brain.
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.)
Mosconi gets the anthropology right. Her foundation is based on two empirical findings. The first one is her studying of the “Blue Zones” or the five areas in the World associated with the greatest proportion of centenarians. And, her second one is her experience as a neuroscientist. She has seen thousands of brain MRIs while knowing what diet her patients ate. She uncovered a link between brain health and diet. The ones who ate a Mediterranean diet had far healthier brains (per MRIs) than the ones on an American diet. She also observed that 2 out of the 5 Blue Zones eat a Mediterranean diets. And, the three other ones have major overlapping components with a Mediterranean diet including complex carbohydrates (fresh produce) that have a lot of fiber, starches (sweet potatoes), nuts, fish, and not much meat and animal protein.
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 best of the old world combined with the science of the new. Huntington Labs offers a Focus, Memory and Clarity supplement that delivers a targeted and specifically stacked combination of nootropics, or “brain enhancers.” Specially chosen extracts, herbs and substances work together to boost attention, creativity, flexibility, focus, speed, memory and clarity. Green Tea Extract: Traditional supplement for mental performance. Promotes better brain function naturally. Huperzine A: Boosts alertness and enhances memory; extracted from Fir moss. Bacopa Monniera: Contains Bacosides which improve cognitive function and memory. L-Glutamine: An essential amino acid that builds protein and aids memory. Huntington Labs pays special attention to the “stacking” benefits of all of these natural nootropic brain boosters, and hopes that you will experience the max benefits from your daily recommended dose. We guarantee it or your money back!

In fact, when combined into a variety of different supplement “stacks” and taken in the correct dosage, these compounds – usually referred to as either smart drugs or nootropics (but now also including the category of psychedelics) – can completely change how your brain performs, including impacting receptor sites for neurotransmitters, altering levels of enzymes that break down specific neurotransmitters, changing cell membrane structures and thus controlling the movement of molecules inside and outside of the cell, increasing cerebral perfusion, which improves blood flow to the brain, affecting what are called “biogenic processes”, including neuronal cell creation or “neurogenesis”, and neuroendocrine regulation, regulating hormonal processes of the body specifically related to cognition (See additional studies here, here, here and here.).

Some people aren’t satisfied with a single supplement—the most devoted self-improvers buy a variety of different compounds online and create their own custom regimens, which they call “stacks.” According to Kaleigh Rogers, writing in Vice last year, companies will now take their customers’ genetic data from 23andMe or another source and use it to recommend the right combinations of smart drugs to optimize each individual’s abilities. The problem with this practice is that there’s no evidence the practice works. (And remember, the FDA doesn’t regulate supplements.) Find out the 9 best foods to boost your brain health.
Common environmental toxins – pesticides, for example – cause your brain to release glutamate (a neurotransmitter). Your brain needs glutamate to function, but when you create too much of it it becomes toxic and starts killing neurons. Oxaloacetate protects rodents from glutamate-induced brain damage.[17] Of course, we need more research to determine whether or not oxaloacetate has the same effect on humans.
…The first time I took supplemental potassium (50% US RDA in a lot of water), it was like a brain fog lifted that I never knew I had, and I felt profoundly energized in a way that made me feel exercise was reasonable and prudent, which resulted in me and the roommate that had just supplemented potassium going for an hour long walk at 2AM. Experiences since then have not been quite so profound (which probably was so stark for me as I was likely fixing an acute deficiency), but I can still count on a moderately large amount of potassium to give me a solid, nearly side effect free performance boost for a few hours…I had been doing Bikram yoga on and off, and I think I wasn’t keeping up the practice because I wasn’t able to properly rehydrate myself.
NeuroFuse was almost there with a top quality product but we felt that there were several key elements missing. It does contain a lot of the top natural ingredients for cognitive energy enhancement. However, the fact that their money-back guarantee is not apparent and that they are baiting customers in using a 14-day free trial offer, made us slightly wary. If they addressed these issues, we felt that this could have been a winner!
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.
A study published in the Journal of Environmental Healths Perspective stated that "researchers, physicians, and others poked around in the dark crevices of the gene, (are) trying to untangle the clues that suggested gene function could be altered by more than just changes in sequence." This ties in perfectly with what Dr. Lisa mentions about how our lifestyles play a crucial role in how/if we manifest a certain cognitive disfunction. Which brings us to our next question: What kind of "brain diet" can help support this lifestyle?
Some people are concerned that when they discontinue the use of nootropics, they will experience cognitive functioning below that of their normal level; however, this is usually not the case, especially regarding nootropics in the racetam class. Discontinuing nootropics will cause a person to lose any benefits experienced on these drugs. In other words, nootropics do not appear to build up the brain in any long-lasting way; their benefits are directly tied to their use. There is no evidence that nootropics erode one’s natural level of cognitive functioning.
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.
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:
Research does not support that drugs like Ritalin help students do well in school. Studies show that prescription stimulants do not help to improve learning or thinking in those who do not actually have ADHD. Further, research reveals that students who abuse prescription stimulants have lower GPAs than students who do not abuse the drugs.[14] Although Ritalin improves concentration, this effect is largely misunderstood among non-prescribed users. These illicit users mistakenly believe that they can use a drug out of its prescribed context, thinking they can reap the benefits intended for legitimate users.

Dr Hart explained how communication between the gut and the brain is controlled via our immune system, our endocrine system (hormones) and our central nervous system, which are all under the influence of the bacteria in our gut. The types and amount of these bacteria, known as our gut microbiome, can be directly impacted by factors such as diet, stress, pollution and medications (2) and the composition of the microbiome is also understood to affect one’s susceptibility to food sensitivities and intolerances (3).  

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.


As it happens, these are areas I am distinctly lacking in. When I first began reading about testosterone I had no particular reason to think it might be an issue for me, but it increasingly sounded plausible, an aunt independently suggested I might be deficient, a biological uncle turned out to be severely deficient with levels around 90 ng/dl (where the normal range for 20-49yo males is 249-839), and finally my blood test in August 2013 revealed that my actual level was 305 ng/dl; inasmuch as I was 25 and not 49, this is a tad low.

From the standpoint of absorption, the drinking of tobacco juice and the interaction of the infusion or concoction with the small intestine is a highly effective method of gastrointestinal nicotine administration. The epithelial area of the intestines is incomparably larger than the mucosa of the upper tract including the stomach, and the small intestine represents the area with the greatest capacity for absorption (Levine 1983:81-83). As practiced by most of the sixty-four tribes documented here, intoxicated states are achieved by drinking tobacco juice through the mouth and/or nose…The large intestine, although functionally little equipped for absorption, nevertheless absorbs nicotine that may have passed through the small intestine.

It makes no sense to ban the use of neuroenhancers. Too many people are already taking them, and the users tend to be educated and privileged people who proceed with just enough caution to avoid getting into trouble. Besides, Anjan Chatterjee is right that there is an apt analogy with plastic surgery. In a consumer society like ours, if people are properly informed about the risks and benefits of neuroenhancers, they can make their own choices about how to alter their minds, just as they can make their own decisions about shaping their bodies.

The use of prescription stimulants is especially prevalent among students.[9] Surveys suggest that 0.7–4.5% of German students have used cognitive enhancers in their lifetime.[10][11][12] Stimulants such as dimethylamylamine and methylphenidate are used on college campuses and by younger groups.[13] Based upon studies of self-reported illicit stimulant use, 5–35% of college students use diverted ADHD stimulants, which are primarily intended for performance enhancement rather than as recreational drugs.[14][15][16] Several factors positively and negatively influence an individual's willingness to use a drug for the purpose of enhancing cognitive performance. Among them are personal characteristics, drug characteristics, and characteristics of the social context.[10][11][17][18]
