Cocoa flavanols (CF) positively influence physiological processes in ways which suggest that their consumption may improve aspects of cognitive function. This study investigated the acute cognitive and subjective effects of CF consumption during sustained mental demand. In this randomized, controlled, double-blinded, balanced, three period crossover trial 30 healthy adults consumed drinks containing 520 mg, 994 mg CF and a matched control, with a 3-day washout between drinks. Assessments included the state anxiety inventory and repeated 10-min cycles of a Cognitive Demand Battery comprising of two serial subtraction tasks (Serial Threes and Serial Sevens), a Rapid Visual Information Processing (RVIP) task and a mental fatigue scale, over the course of 1 h. Consumption of both 520 mg and 994 mg CF significantly improved Serial Threes performance. The 994 mg CF beverage significantly speeded RVIP responses but also resulted in more errors during Serial Sevens. Increases in self-reported mental fatigue were significantly attenuated by the consumption of the 520 mg CF beverage only. This is the first report of acute cognitive improvements following CF consumption in healthy adults. While the mechanisms underlying the effects are unknown they may be related to known effects of CF on endothelial function and blood flow.
But before you dismiss the diet-brain connection as mere conjecture, keep in mind that study after study has found a relationship between what we put in our mouths and how well we can perform important thinking and memory tasks. While certain nutrients may specifically assist brain function, there is also the totality of our diets to consider. One recent U.K. study found that a diet high in saturated fat actually caused damage to neurons that control energy and appetite in mice. And several well-regarded studies have shown that meal timing is an important predictor of performance. For example, research shows that eating breakfast can improve the memory and acquisition skills of schoolchildren.
And if you obtain your vitamin C from a multivitamin, you receive other key nutrients that many studies over the years have linked to healthy brain function, including beta carotene, iron, zinc, B12 and folic acid. In the June 1999 issue of the Journal of Biology and Psychiatry, for instance, researchers at Sweden's Gotenborg University reported that older people were more likely to score poorly on word memory tests if they had low levels of folic acid.
There are many books about nutrition and cognitive functions. The authors ground their nutrition protocol on what humans ate during the paleolithic era. Often these authors contradict each other. For some, we were better hunters than gatherers so we ate mostly meat. For others, we were better gatherers and ate primarily nuts, plants, fruits. Others advance our digestive system can’t tolerate grains because it was a modern invention of the first agricultural revolution (about 10,000 years ago).
"More and more of our young people are using these drugs to help them work. They've got their laptop, their iPhone, and their Adderall. This rising generation of workers and leaders may have a subtly different style of thinking and working, because they're using these drugs or because they learned to work using these drugs, so that even if you take the drugs away they'll still have a certain approach. I'm a little concerned that we could be raising a generation of very focused accountants."
Walnuts in particular are excellent brain food. These wrinkly nuts—which kind of resemble the human brain—are rich in vitamin E. Researchers at Chicago’s Rush University Medical Center studied the lifestyle habits of 6,000 people who were unaffected by Alzheimer’s the memory-robbing condition, and found that those who ate the most vitamin E-rich foods had a reduced risk of developing the memory-robbing condition. Vitamin E may trap free radicals that can damage brain cells, according to the Alzheimer’s Research Center. Here’s some more brain food that your noggin will thank you for eating.
DNB-wise, eyeballing my stats file seems to indicate a small increase: when I compare peak scores D4B scores, I see mostly 50s and a few 60s before piracetam, and after starting piracetam, a few 70s mixed into the 50s and 60s. Natural increase from training? Dunno - I’ve been stuck on D4B since June, so 5 or 10% in a week or 3 seems a little suspicious. A graph of the score series27:
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.
The AC-11 that Marcus mentioned for health is an extract from the Amazon jungle vine una de gato, and has been shown in laboratory and clinical trials to encourage DNA repair. The Mucuna pruriens he named for motivation is a legume that's a concentrated source of L-Dopa, which the body converts to the neurotransmitter dopamine. The Huperzia serrata Marcus selected for hunting is the same substance that induces lucid dreaming. This seems appropriate. While I felt the Alpha Brain helped my hunting, maybe I was dreaming. Or maybe a dream state of mind is good for hunting.
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.
On the plus side: - I noticed the less-fatigue thing to a greater extent, getting out of my classes much less tired than usual. (Caveat: my sleep schedule recently changed for the saner, so it’s possible that’s responsible. I think it’s more the piracetam+choline, though.) - One thing I wasn’t expecting was a decrease in my appetite - nobody had mentioned that in their reports.I don’t like being bothered by my appetite (I know how to eat fine without it reminding me), so I count this as a plus. - Fidgeting was reduced further
Choosing to take smart drugs is not an effective or long term solution. Smart drugs may help you study faster or keep you awake longer, but they are not your best option. Most of the ADHD medications are based on an amphetamine structure and they are not healthy for your heart or your liver. Also, by taking smart drugs, you are putting yourself at considerable risk for addiction to these substances.
It’s 3 p.m., and I am crushing my e-mail inbox. At this time of day, I’m typically struggling to stave off the post-lunch slowdown by downing another cup of coffee or two. But today, message after message is flying off my fingertips effortlessly—work e-mail, personal e-mail, digital errands I’d been meaning to run for months. I’m in the zone, as they say, and for this burst of late afternoon productivity, I might have nootropics to thank.
20 March, 2x 13mg; first time, took around 11:30AM, half-life 3 hours, so halved by 2:30PM. Initial reaction: within 20 minutes, started to feel light-headed, experienced a bit of physical clumsiness while baking bread (dropped things or poured too much thrice); that began to pass in an hour, leaving what felt like a cheerier mood and less anxiety. Seems like it mostly wore off by 6PM.

Caffeine (Examine.com; FDA adverse events) is of course the most famous stimulant around. But consuming 200mg or more a day, I have discovered the downside: it is addictive and has a nasty withdrawal - headaches, decreased motivation, apathy, and general unhappiness. (It’s a little amusing to read academic descriptions of caffeine addiction9; if caffeine were a new drug, I wonder what Schedule it would be in and if people might be even more leery of it than modafinil.) Further, in some ways, aside from the ubiquitous placebo effect, caffeine combines a mix of weak performance benefits (Lorist & Snel 2008, Nehlig 2010) with some possible decrements, anecdotally and scientifically:
Pre and Post-Natal Depression are both complex conditions that can have multifactorial underlying drivers, including genetic and environmental influences. These are currently poorly investigated and the gold standard of treatment is often medication to help stabilise mood. Whilst SSRIs and other types of antidepressants have proven to be helpful for many, they do not address potential causes or drivers of poor mental health and can often mask symptoms. Antidepressants are also not regularly recommended during pregnancy, which is why being more mindful of nutrition and lifestyle habits can be a safer option for you and your baby. There are some natural, evidence-based steps you can take to help support optimal mental wellbeing:
The compound has great nootropic properties that includes memory enhancement and protection against brain aging. There are studies that suggest that the compound is an effective treatment for disorders like vascular dementia, Alzheimer’s, brain stroke, anxiety and depression. However, there are some side effects associated with Alpha GPC, like headache, heartburn, dizziness, skin rashes, insomnia, and confusion.
However, despite these apparent good results, it’s recommended that you don’t run to the pharmacy just yet. The long term effects of taking Modafinil haven’t been studied conclusively or in-depth yet; to the contrary and in direct opposition to the many claims that Modafinil is completely safe, 50% of modafinil users report a number of short term side effects, such as mild to severe headaches, insomnia, nausea, anxiety, nervousness, hypertension, decreased appetite, and weight loss.
Amphetamines are synthetic stimulants and were first created in 1887. These are among the most powerful stimulant-based smart drugs in use and work primarily by targeting dopamine, serotonin and noradrenaline/norepinephrine. Given what you’ve already learned about the dopaminergic effects of modafinil and methylphenidate, you should already be wary of amphetamines’ targeting of dopamine. Hormones and neurotransmitters such as dopamine, serotonin, norepinephrine and histamine are known as monoamines, and amphetamines block their uptake by being taken up instead themselves by monoamine transporters. This leads to higher levels of monoamines in synapses, and consequently to the psychostimulant effects characteristic of drugs like Adderall.
Nicotine absorption through the stomach is variable and relatively reduced in comparison with absorption via the buccal cavity and the small intestine. Drinking, eating, and swallowing of tobacco smoke by South American Indians have frequently been reported. Tenetehara shamans reach a state of tobacco narcosis through large swallows of smoke, and Tapirape shams are said to eat smoke by forcing down large gulps of smoke only to expel it again in a rapid sequence of belches. In general, swallowing of tobacco smoke is quite frequently likened to drinking. However, although the amounts of nicotine swallowed in this way - or in the form of saturated saliva or pipe juice - may be large enough to be behaviorally significant at normal levels of gastric pH, nicotine, like other weak bases, is not significantly absorbed.
I posted a link to the survey on my Google+ account, and inserted the link at the top of all gwern.net pages; 51 people completed all 11 binary choices (most of them coming from North America & Europe), which seems adequate since the 11 questions are all asking the same question, and 561 responses to one question is quite a few. A few different statistical tests seem applicable: a chi-squared test whether there’s a difference between all the answers, a two-sample test on the averages, and most meaningfully, summing up the responses as a single pair of numbers and doing a binomial test:
I usually use Alpha Brain but have found the delivery times and cost per bottle to be too much .Its great to find a UK based nootropic supplement company giving Alpha Brain a run for their Yankee Dollar . Ultra is a very smooth nootropic - i find my thinking clear and my brain feels more alert and alive - hard to explain but Ultra makes me feel more 'present' and alive . Highly recommended. 5 STARS!

To our volunteers: We could not have asked for a more committed, creative, tireless group of voluneers. We hope you count yourself as fierce advocates who helped build a youth-positive city, because we always have. Thank you for giving Brainfood programs a place in your life and for bringing your energy and skills to our community. You took our spark and turned it into a fire, and we’re so grateful.
Elaborating on why the psychological side effects of testosterone injection are individual dependent: Not everyone get the same amount of motivation and increased goal seeking from the steroid and most people do not experience periods of chronic avolition. Another psychological effect is a potentially drastic increase in aggression which in turn can have negative social consequences. In the case of counterfactual Wedrifid he gets a net improvement in social consequences. He has observed that aggression and anger are a prompt for increased ruthless self-interested goal seeking. Ruthless self-interested goal seeking involves actually bothering to pay attention to social politics. People like people who do social politics well. Most particularly it prevents acting on contempt which is what Wedrifid finds prompts the most hostility and resentment in others. Point is, what is a sanity promoting change in one person may not be in another.
As with any thesis, there are exceptions to this general practice. For example, theanine for dogs is sold under the brand Anxitane is sold at almost a dollar a pill, and apparently a month’s supply costs $50+ vs $13 for human-branded theanine; on the other hand, this thesis predicts downgrading if the market priced pet versions higher than human versions, and that Reddit poster appears to be doing just that with her dog.↩
Second, users are concerned with the possibility of withdrawal if they stop taking the nootropics. They worry that if they stop taking nootropics they won’t be as smart as when they were taking nootropics, and will need to continue taking them to function. Some users report feeling a slight brain fog when discontinuing nootropics, but that isn’t a sign of regression.
