Whether you want to optimise your nutrition during exam season or simply want to stay sharp in your next work meeting, paying attention to your diet can really pay off. Although there is no single 'brain food' that can protect against age-related disorders such as Alzheimers' or dementia, and there are many other medical conditions that can affect the brain, paying attention to what you eat gives you the best chance of getting all the nutrients you need for cognitive health.
But there’s a surprising lack of skepticism in the room. That’s because this is a weekly meetup of amateur biohackers. In fact, positivity is one of their ground rules. Members share experiences with ketogenic diets, biofeedback apps, sensory-deprivation tanks, and, lately, a class of smart drugs known as “nootropics.” Their primary obsession is brain enhancement.
(If I am not deficient, then supplementation ought to have no effect.) The previous material on modern trends suggests a prior >25%, and higher than that if I were female. However, I was raised on a low-salt diet because my father has high blood pressure, and while I like seafood, I doubt I eat it more often than weekly. I suspect I am somewhat iodine-deficient, although I don’t believe as confidently as I did that I had a vitamin D deficiency. Let’s call this one 75%.
Regardless, while in the absence of piracetam, I did notice some stimulant effects (somewhat negative - more aggressive than usual while driving) and similar effects to piracetam, I did not notice any mental performance beyond piracetam when using them both. The most I can say is that on some nights, I seemed to be less easily tired when writing or editing or n-backing (and I felt less tired than ICON 2011 than ICON 2010), but those were also often nights I was also trying out all the other things I had gotten in that order from Smart Powders, and I am still dis-entangling what was responsible. (Probably the l-theanine or sulbutiamine.)
Ngo has experimented with piracetam himself (“The first time I tried it, I thought, ‘Wow, this is pretty strong for a supplement.’ I had a little bit of reflux, heartburn, but in general it was a cognitive enhancer. . . . I found it helpful”) and the neurotransmitter DMEA (“You have an idea, it helps you finish the thought. It’s for when people have difficulty finishing that last connection in the brain”).
On the other metric, suppose we removed the creatine? Dropping 4 grams of material means we only need to consume 5.75 grams a day, covered by 8 pills (compared to 13 pills). We save 5,000 pills, which would have cost $45 and also don’t spend the $68 for the creatine; assuming a modafinil formulation, that drops our $1761 down to $1648 or $1.65 a day. Or we could remove both the creatine and modafinil, for a grand total of $848 or $0.85 a day, which is pretty reasonable.
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.

Chocolate or cocoa powder (Examine.com), contains the stimulants caffeine and the caffeine metabolite theobromine, so it’s not necessarily surprising if cocoa powder was a weak stimulant. It’s also a witch’s brew of chemicals such as polyphenols and flavonoids some of which have been fingered as helpful10, which all adds up to an unclear impact on health (once you control for eating a lot of sugar).
Upon examining the photographs, I noticed no difference in eye color, but it seems that my move had changed the ambient lighting in the morning and so there was a clear difference between the two sets of photographs! The before photographs had brighter lighting than the after photographs. Regardless, I decided to run a small survey on QuickSurveys/Toluna to confirm my diagnosis of no-change; the survey was 11 forced-choice pairs of photographs (before-after), with the instructions as follows:
Can the Folic Acid in this Supplement be Taken by Men? Folic acid is most well-known for its use in prenatal vitamins during pregnancy and breastfeeding. However, it is an important nutrient for the bodies of both men and women. The level of folic acid in Cognizance is nowhere near as high as the levels found in prenatal vitamins taken during pregnancy, making it safe for use by both genders. Is it Safe? All of the ingredients in Cognizance have been tested individually for their safety of use. They have also been monitored in use together, to ensure there are no side effects from the combination of ingredients.1 Though Cognizance is safe, you should still speak to your doctor if you are under the age of 18, have a pre-existing medical condition, or are a woman who is pregnant or nursing.
Adderall is composed of a mixture of amphetamine salts – chemical compounds that have numerous potentially positive effects, including increased concentration, awareness and alertness. Amphetamines work, in part, by causing the release of dopamine, a neurotransmitter associated with pleasurable activities like eating. However, an amphetamine-induced release of dopamine occurs automatically – no pleasurable activity needs to occur – but a come-down feeling will likely be experienced eventually, which is associated with feelings of lethargy and mental dullness. Due to this side effect, Adderall cannot be said to be a nootropic.[12]
A total of 330 randomly selected Saudi adolescents were included. Anthropometrics were recorded and fasting blood samples were analyzed for routine analysis of fasting glucose, lipid levels, calcium, albumin and phosphorous. Frequency of coffee and tea intake was noted. 25-hydroxyvitamin D levels were measured using enzyme-linked immunosorbent assays…Vitamin D levels were significantly highest among those consuming 9-12 cups of tea/week in all subjects (p-value 0.009) independent of age, gender, BMI, physical activity and sun exposure.
The hormone testosterone (Examine.com; FDA adverse events) needs no introduction. This is one of the scariest substances I have considered using: it affects so many bodily systems in so many ways that it seems almost impossible to come up with a net summary, either positive or negative. With testosterone, the problem is not the usual nootropics problem that that there is a lack of human research, the problem is that the summary constitutes a textbook - or two. That said, the 2011 review The role of testosterone in social interaction (excerpts) gives me the impression that testosterone does indeed play into risk-taking, motivation, and social status-seeking; some useful links and a representative anecdote:

The team behind Brain Pill strongly believes in fair win-win scenarios. That’s why every customer has an opportunity to try this product for the full two months. There’s nothing to worry about during this period because you are covered by the no-questions-asked money-back guarantee. Some people begin experiencing the first obvious results in less than a month. On the other hand, some users require up to 60 days to see Brain Pill at work full scale. It’s an individual thing. If you aren’t absolutely thrilled by Brain Pill’s results after two months of use, you are free to ask for the full refund. It’s that simple and fair. In addition, you get an extra week after the initial period of 60 days expired to send back the bottles you haven’t used. You will either get all the benefits or get the full refund. So, this risk-free opportunity just can’t get any better, can it?
The soft gels are very small; one needs to be a bit careful - Vitamin D is fat-soluble and overdose starts in the range of 70,000 IU36, so it would take at least 14 pills, and it’s unclear where problems start with chronic use. Vitamin D, like many supplements, follows a U-shaped response curve (see also Melamed et al 2008 and Durup et al 2012) - too much can be quite as bad as too little. Too little, though, is likely very bad. The previously cited studies with high acute doses worked out to <1,000 IU a day, so they may reassure us about the risks of a large acute dose but not tell us much about smaller chronic doses; the mortality increases due to too-high blood levels begin at ~140nmol/l and reading anecdotes online suggest that 5k IU daily doses tend to put people well below that (around 70-100nmol/l). I probably should get a blood test to be sure, but I have something of a needle phobia.

…It is without activity in man! Certainly not for the lack of trying, as some of the dosage trials that are tucked away in the literature (as abstracted in the Qualitative Comments given above) are pretty heavy duty. Actually, I truly doubt that all of the experimenters used exactly that phrase, No effects, but it is patently obvious that no effects were found. It happened to be the phrase I had used in my own notes.


The metal magnesium (Examine.com), like potassium (which didn’t help me), plays many biological roles and has an RDA for me of 400mg which is higher than I likely get (most people apparently get less, with 68% of American adults
If you are looking for a way to maximize brain power I have come across a great product named Brain Abundance. Here are a list of the ingridients, folic acid, grape seed extract, L-Glutamine, phenylalanine, sensoril, rhodiola, vitamin b-12, astaxanthin, niacinamide, zinc picolinate, resveratrol, vitamin b-6, ginseng. I have personally taken this product and have had great results with the following: cognitive function, healthy memory, stress and anxiety, positive mood and mind, better sleep, focus and mental clarity, and much more. Feel free to find out more information at:
“We stumbled upon fasting as a way to optimize cognition and make yourself into a more efficient human being,” says Manuel Lam, an internal medicine physician who advises Nootrobox on clinical issues. He and members of the company’s executive team have implanted glucose monitors in their arms — not because they fear diabetes but because they wish to track the real-time effect of the foods they eat.
So, I have started a randomized experiment; should take 2 months, given the size of the correlation. If that turns out to be successful too, I’ll have to look into methods of blinding - for example, some sort of electronic doohickey which turns on randomly half the time and which records whether it’s on somewhere one can’t see. (Then for the experiment, one hooks up the LED, turns the doohickey on, and applies directly to forehead, checking the next morning to see whether it was really on or off).
Your brain is essentially a network of billions of neurons connected by synapses. These neurons communicate and work together through chemicals known as neurotransmitters. When neurotransmitters are able to send signals more efficiently, you experience improved concentration, better memory, mood elevation, increased processing ability for mental work, and longer attention spans.
This would be a very time-consuming experiment. Any attempt to combine this with other experiments by ANOVA would probably push the end-date out by months, and one would start to be seriously concerned that changes caused by aging or environmental factors would contaminate the results. A 5-year experiment with 7-month intervals will probably eat up 5+ hours to prepare <12,000 pills (active & placebo); each switch and test of mental functioning will probably eat up another hour for 32 hours. (And what test maintains validity with no practice effects over 5 years? Dual n-back would be unusable because of improvements to WM over that period.) Add in an hour for analysis & writeup, that suggests >38 hours of work, and 38 \times 7.25 = 275.5. 12,000 pills is roughly $12.80 per thousand or $154; 120 potassium iodide pills is ~$9, so \frac{365.25}{120} \times 9 \times 5 = 137.
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.
The general cost of fish oil made me interested in possible substitutes. Seth Roberts uses exclusively flaxseed oil or flaxseed meal, and this seems to work well for him with subjective effects (eg. noticing his Chinese brands seemed to not work, possibly because they were unrefrigerated and slightly rancid). It’s been studied much less than fish oil, but omega acids are confusing enough in general (is there a right ratio? McCluskey’s roundup gives the impression claims about ratios may have been overstated) that I’m not convinced ALA is a much inferior replacement for fish oil’s mixes of EPA & DHA.
By analyzing the brain images, the team found that these patients, compared with people who weren’t susceptible to the placebo, had a difference in volume between the right and left sides of the limbic system in the brain, which is involved in instinct and mood. There were also differences in the number of nerve cell connections between the prefrontal cortex and other brain areas. Personality questionnaires revealed that these people had a higher self-awareness and openness than nonresponders.

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.)
…researchers have added a new layer to the smart pill conversation. Adderall, they’ve found, makes you think you’re doing better than you actually are….Those subjects who had been given Adderall were significantly more likely to report that the pill had caused them to do a better job….But the results of the new University of Pennsylvania study, funded by the U.S. Navy and not yet published but presented at the annual Society for Neuroscience conference last month, are consistent with much of the existing research. As a group, no overall statistically-significant improvement or impairment was seen as a result of taking Adderall. The research team tested 47 subjects, all in their 20s, all without a diagnosis of ADHD, on a variety of cognitive functions, from working memory-how much information they could keep in mind and manipulate-to raw intelligence, to memories for specific events and faces….The last question they asked their subjects was: How and how much did the pill influence your performance on today’s tests? Those subjects who had been given Adderall were significantly more likely to report that the pill had caused them to do a better job on the tasks they’d been given, even though their performance did not show an improvement over that of those who had taken the placebo. According to Irena Ilieva…it’s the first time since the 1960s that a study on the effects of amphetamine, a close cousin of Adderall, has asked how subjects perceive the effect of the drug on their performance.
Cytisine is not known as a stimulant and I’m not addicted to nicotine, so why give it a try? Nicotine is one of the more effective stimulants available, and it’s odd how few nicotine analogues or nicotinic agonists there are available; nicotine has a few flaws like short half-life and increasing blood pressure, so I would be interested in a replacement. The nicotine metabolite cotinine, in the human studies available, looks intriguing and potentially better, but I have been unable to find a source for it. One of the few relevant drugs which I can obtain is cytisine, from Ceretropic, at 2x1.5mg doses. There are not many anecdotal reports on cytisine, but at least a few suggest somewhat comparable effects with nicotine, so I gave it a try.
Now, what is the expected value (EV) of simply taking iodine, without the additional work of the experiment? 4 cans of 0.15mg x 200 is $20 for 2.1 years’ worth or ~$10 a year or a NPV cost of $205 (\frac{10}{\ln 1.05}) versus a 20% chance of $2000 or $400. So the expected value is greater than the NPV cost of taking it, so I should start taking iodine.
For illustration, consider amphetamines, Ritalin, and modafinil, all of which have been proposed as cognitive enhancers of attention. These drugs exhibit some positive effects on cognition, especially among individuals with lower baseline abilities. However, individuals of normal or above-average cognitive ability often show negligible improvements or even decrements in performance following drug treatment (for details, see de Jongh, Bolt, Schermer, & Olivier, 2008). For instance, Randall, Shneerson, and File (2005) found that modafinil improved performance only among individuals with lower IQ, not among those with higher IQ. [See also Finke et al 2010 on visual attention.] Farah, Haimm, Sankoorikal, & Chatterjee 2009 found a similar nonlinear relationship of dose to response for amphetamines in a remote-associates task, with low-performing individuals showing enhanced performance but high-performing individuals showing reduced performance. Such ∩-shaped dose-response curves are quite common (see Cools & Robbins, 2004)
First half at 6 AM; second half at noon. Wrote a short essay I’d been putting off and napped for 1:40 from 9 AM to 10:40. This approach seems to work a little better as far as the aboulia goes. (I also bother to smell my urine this time around - there’s a definite off smell to it.) Nights: 10:02; 8:50; 10:40; 7:38 (2 bad nights of nasal infections); 8:28; 8:20; 8:43 (▆▃█▁▂▂▃).
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.

Power-wise, the effects of testosterone are generally reported to be strong and unmistakable. Even a short experiment should work. I would want to measure DNB scores & Mnemosyne review averages as usual, to verify no gross mental deficits; the important measures would be physical activity, so either pedometer or miles on treadmill, and general productivity/mood. The former 2 variables should remain the same or increase, and the latter 2 should increase.
Of course, before wrapping up this section on psychedelics, I’ll address the topics of where to actually buy the stuff. There are a variety of websites that sell psychedelics, but not all ingredient, chemical or quality sourcing is created equal, nor is there any guarantee that any substance you are purchasing is not laced with undesirable compounds. Heck, I get my psilocybin from a farmer in Wisconsin who is a personal friend, and other ingredients from close acquaintances who have their own sources. I know it may seem unfair, but sometimes sourcing comes down to “who ya know” and doing your own due diligence on that person’s source.
Today, extraordinary research is showing that bacopa has the remarkable ability to increase levels of BDNF, a protein responsible for the growth, maintenance and survival of neurons, and the creation of new neural connections in the brain. It also has been shown to help promote the growth of new neurons and neural pathways, which helps to explain why it’s such a powerful memory and concentration booster.
Attention Deficit and Hyperactivity Disorder (ADHD) is a condition that relates to a collection of behavioural symptoms such as hyperactivity, impulsiveness and inattentiveness. It is most commonly diagnosed in childhood between the ages of 6 and 12 when disruptive behaviour begins to show, however, due to a growing awareness of the condition, it is also becoming common among adults. According to the thinktank Demos, the cost of undiagnosed ADHD in adults in the UK who are unable to work or hold down a full-time job are estimated to cost billions of pounds to the nation. They warn that too many may be going through life struggling, unable to access the support ot diagnosis they need, which means there could be a huge amount of wasted talent.
You’ve no doubt heard that we’re now entering a new golden age of psychedelics, and microdosing with LSD, psilocybin, ketamine and other compounds previously placed in the realm of party animals and rave enthusiasts is now commonplace for CEO’s, the Navy SEALs, famous authors and beyond. You no longer have to be a tree-hugging, anti-war rebel to achieve the many positive health benefits of psychedelics. My own personal experience with these compounds has spanned several years of quarterly heavy psilocybin and DMT dosages for personal self-discovery, weekly LSD microdoses for creativity and productivity, and iboga microdosing for a pre-workout boost.
My predictions were substantially better than random chance7, so my default belief - that Adderall does affect me and (mostly) for the better - is borne out. I usually sleep very well and 3 separate incidents of horrible sleep in a few weeks seems rather unlikely (though I didn’t keep track of dates carefully enough to link the Zeo data with the Adderall data). Between the price and the sleep disturbances, I don’t think Adderall is personally worthwhile.
I stayed up late writing some poems and about how [email protected] kills, and decided to make a night of it. I took the armodafinil at 1 AM; the interesting bit is that this was the morning/evening after what turned out to be an Adderall (as opposed to placebo) trial, so perhaps I will see how well or ill they go together. A set of normal scores from a previous day was 32%/43%/51%/48%. At 11 PM, I scored 39% on DNB; at 1 AM, I scored 50%/43%; 5:15 AM, 39%/37%; 4:10 PM, 42%/40%; 11 PM, 55%/21%/38%. (▂▄▆▅ vs ▃▅▄▃▃▄▃▇▁▃)
Last April the scientific journal Nature published the results of an informal online poll asking whether readers attempted to sharpen "their focus, concentration, or memory" by taking drugs such as Ritalin and Provigil, a newer kind of stimulant, known generically as modafinil, which was developed to treat narcolepsy. One in five respondents said they did. A majority of the 1,400 readers who responded said that healthy adults should be permitted to take brain boosters for non-medical reasons, and 69% said that mild side-effects were an acceptable risk. Though a majority said that such drugs should not be made available to children who had no diagnosed medical condition, a third admitted that they would feel pressure to give "smart drugs" to their kids if they learned that other parents were doing so.
A protein source linked to a great brain boost is fish -- rich in omega-3 fatty acids that are key for brain health. These healthy fats have amazing brain power: A diet with higher levels of them has been linked to lower dementia and stroke risks and slower mental decline; plus, they may play a vital role in enhancing memory, especially as we get older.

"In an era of confusion about what we should eat, Brain Food is a shining light. This is the straight story about 'neuro-nutrition' firmly rooted in research by a neuroscientist who has a deep understanding of how food affects our cognitive health. Dr. Mosconi gives us advice we can easily implement into our lives and a story about the science behind it that is both delightful and accessible. A must read!"


Caffeine metabolism is primarily determined by the cytochrome enzyme P-450 1A2 (CYP1A2), and studies have shown that different ethnic populations exhibit widely varying expressions of the gene responsible for CYP1A2. Evidence suggests that a particular CYP1A2 impacts caffeine consumption by modifying the risks of certain diseases that are associated with caffeine consumption. It has also been shown that variations in the expression of genes that code for adenosine and dopamine receptors play a role in mediating your response to caffeine. For example, in Caucasians, the presence of certain genetic expressions for both adenosine and dopamine receptors is associated with caffeine-induced anxiety. Variations in CYP1A2 are also responsible for the speed at which different people metabolize caffeine.

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.
