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.
These pills don’t work. The reality is that MOST of these products don’t work effectively. Maybe we’re cynical, but if you simply review the published studies on memory pills, you can quickly eliminate many of the products that don’t have “the right stuff.” The active ingredients in brain and memory health pills are expensive and most companies sell a watered down version that is not effective for memory and focus. The more brands we reviewed, the more we realized that many of these marketers are slapping slick labels on low-grade ingredients.

Take at 11 AM; distractions ensue and the Christmas tree-cutting also takes up much of the day. By 7 PM, I am exhausted and in a bad mood. While I don’t expect day-time modafinil to buoy me up, I do expect it to at least buffer me against being tired, and so I conclude placebo this time, and with more confidence than yesterday (65%). I check before bed, and it was placebo.
The fish oil can be considered a free sunk cost: I would take it in the absence of an experiment. The empty pill capsules could be used for something else, so we’ll put the 500 at $5. Filling 500 capsules with fish and olive oil will be messy and take an hour. Taking them regularly can be added to my habitual morning routine for vitamin D and the lithium experiment, so that is close to free but we’ll call it an hour over the 250 days. Recording mood/productivity is also free a sunk cost as it’s necessary for the other experiments; but recording dual n-back scores is more expensive: each round is ~2 minutes and one wants >=5, so each block will cost >10 minutes, so 18 tests will be >180 minutes or >3 hours. So >5 hours. Total: 5 + (>5 \times 7.25) = >41.

For 2 weeks, upon awakening I took close-up photographs of my right eye. Then I ordered two jars of Life-Extension Sea-Iodine (60x1mg) (1mg being an apparently safe dose), and when it arrived on 10 September 2012, I stopped the photography and began taking 1 iodine pill every other day. I noticed no ill effects (or benefits) after a few weeks and upped the dose to 1 pill daily. After the first jar of 60 pills was used up, I switched to the second jar, and began photography as before for 2 weeks. The photographs were uploaded, cropped by hand in Gimp, and shrunk to more reasonable dimensions; both sets are available in a Zip file.
11:30 AM. By 2:30 PM, my hunger is quite strong and I don’t feel especially focused - it’s difficult to get through the tab-explosion of the morning, although one particularly stupid poster on the DNB ML makes me feel irritated like I might on Adderall. I initially figure the probability at perhaps 60% for Adderall, but when I wake up at 2 AM and am completely unable to get back to sleep, eventually racking up a Zeo score of 73 (compared to the usual 100s), there’s no doubt in my mind (95%) that the pill was Adderall. And it was the last Adderall pill indeed.
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?
An unusual intervention is infrared/near-infrared light of particular wavelengths (LLLT), theorized to assist mitochondrial respiration and yielding a variety of therapeutic benefits. Some have suggested it may have cognitive benefits. LLLT sounds strange but it’s simple, easy, cheap, and just plausible enough it might work. I tried out LLLT treatment on a sporadic basis 2013-2014, and statistically, usage correlated strongly & statistically-significantly with increases in my daily self-ratings, and not with any sleep disturbances. Excited by that result, I did a randomized self-experiment 2014-2015 with the same procedure, only to find that the causal effect was weak or non-existent. I have stopped using LLLT as likely not worth the inconvenience.

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
They reduce inflammation, are high in cancer-protecting antioxidants and help rid your blood of toxins. The natural nitrates in beets actually boost blood flow to the brain, helping with mental performance. Plus, during tough workouts, beets actually help boost energy and performance levels. I love them roasted or in salads — try my sweet potato beet hash or beet and goat cheese salad for some creative new ways to eat this brain food.
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.
The human drive to be smarter is a familiar theme on the big screen. In 2011, Oscar-nominated actor Bradley Cooper played struggling writer Eddie Morra in the sci-fi thriller Limitless. In the film, Morra acquires a (fictitious) nootropic NZT-48 that allows him to access 100 percent of his mind. Although he finds himself in lots of trouble, his use of the nootropic transforms him from a desperate writer to a multimillionaire who ultimately runs for the U.S. Senate. The film is a testament to a dream deeply entrenched in the American psyche – that an everyman can become superhuman and lead an extraordinary life.
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 you are no doubt well aware, coffee and cigarettes have long been a popular combination. Ah, nostalgia. Just think back to the 1950’s and the man in the suit perfectly pairing his black brew with a cigarette hanging out the corner of his mouth as he enjoyed the Sunday paper or rocked on a lazy afternoon out on the family patio. Heck, there’s even a movie called “Coffee and Cigarettes” and a song called “Cigarettes & Coffee” (in the former, you can see Bill Murray, Tom Waits, Steve Buscemi and Cate Blanchett partaking in their fair share of smoking and sipping).
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.
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?
Zach was on his way to being a doctor when a personal health crisis changed all of that. He decided that he wanted to create wellness instead of fight illness. He lost over a 100 lbs through functional nutrition and other natural healing protocols. He has since been sharing his knowledge of nutrition and functional medicine for the last 12 years as a health coach and health educator.

The power calculation indicates a 20% chance of getting useful information. My quasi-experiment has <70% chance of being right, and I preserve a general skepticism about any experiment, even one as well done as the medical student one seems to be, and give that one a <80% chance of being right; so let’s call it 70% the effect exists, or 30% it doesn’t exist (which is the case in which I save money by dropping fish oil for 10 years).
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.
Please take care when you’re out there on the web or in the world shopping for something to help that in progress novel or craft project of yours along. Take all care when planning on taking anything, be it a nootropic, smart drug, or brain enhancer, and do your research before buying. Make sure your so-called ‘best brain pill’ really is the best brain pill for you.
Just like throughout pregnancy, nutritional needs after birth, especially if breastfeeding, are incredibly important. The healthier the diet, the easier it will be to sustain the energy needed to take care of a newborn. Research shows that a breastfeeding mother needs an extra 300-500 calories a day, from food that is rich in the right macro and micronutrients to nourish both mother and baby (3). For example, nutrients such as B vitamins have shown to be important in supporting the mother in ensuring she has enough energy to meet the demands of lactation (4). These nutrients can be found in green leafy vegetables, wholegrains and good sources of animal protein. 

It is incredibly easy to abuse and become addicted to methylphenidate, and misuse is shockingly prevalent, even among so-called “non-affected” users: with students, biohackers, soccer moms and busy executives popping it – and many of the other smart drugs below – like candy. It’s also not all it’s cracked up to be. Side effects include insomnia, stomach ache, headache and anorexia. Overdoses (which may occur easily as it can be difficult to estimate and regulate dosage) can lead to agitation, hallucinations, psychosis, lethargy, seizures, tachycardia (rapid heart rate), dysrhythmia (irregular heart rhythms), hypertension and hyperthermia. Methylphenidate is particularly hazardous to developing brains, especially those of younger students who are frequently prescribed the drug or who – often in high school and college – use it without a prescription. The prefrontal cortex, located behind the forehead, is responsible for cognition, personality-expression and decision-making, and develops well into the mid-20s, at which point it takes over as the “rational” part of the brain. In the central nervous system, and particularly in the prefrontal cortex, dopamine levels must have a natural rise and fall in order for healthy rational processes (executive control) to develop. By influencing dopamine levels, methylphenidate can negatively impact this healthy cognitive development, especially when it is abused or used too frequently.
But what does this all have to do with food? Our gut helps keep our body’s immune responses and inflammation under control. Additionally, gut hormones that enter the brain or are produced in the brain influence cognitive ability, like understanding and processing new information, staying focused on the task at hand and recognizing when we’re full.

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)
-Water [is also important]. Over 80% of the brain’s content is water. Every chemical reaction that takes place in the brain needs water, especially energy production. The brain is so sensitive to dehydration that even a minimal loss of water can cause symptoms like brain fog, fatigue, dizziness, confusion and, more importantly, brain shrinkage. The longevity and well-being of your brain are critically dependent upon consuming hard water. This refers to plain water that is high in minerals and natural electrolytes. Most people don’t realize that the water they’re drinking is not actually “water”.
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.

Both nootropics startups provide me with samples to try. In the case of Nootrobox, it is capsules called Sprint designed for a short boost of cognitive enhancement. They contain caffeine – the equivalent of about a cup of coffee, and L-theanine – about 10 times what is in a cup of green tea, in a ratio that is supposed to have a synergistic effect (all the ingredients Nootrobox uses are either regulated as supplements or have a “generally regarded as safe” designation by US authorities)
Burke says he definitely got the glow. “The first time I took it, I was working on a business plan. I had to juggle multiple contingencies in my head, and for some reason a tree with branches jumped into my head. I was able to place each contingency on a branch, retract and go back to the trunk, and in this visual way I was able to juggle more information.”
Effect of Brain Pill on working memory capacity will be accessed by improvement in mean response time and accuracy measured by working memory battery from baseline to end of the study. Effect of Brain Pill is also accessed on Neurophysiological improvement in working memory as measured by electroencephelogram (EEG) from baseline to end of the study. Also improvement in attention and concentration will be accessed from baseline to end of the study by Picture recognition test.
