Reason: Besides keeping cells intact, this membrane performs vital functions. These actions include moving nutrients into cells and pumping waste products out of them. Investigators in one study determined that phosphatidyl serine shaved 12 years off the normal expected decline. This result was present in specific aspects of memory performance. Phosphatidyl serine is shown in studies to boost cognitive function. This occurs by increasing communication between brain cells. Those who took 100 mg of phosphatidyl serine three times a day, with meals for 12 weeks scored 30% higher on memory and learning tests.
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.
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)
Nootropics still exist largely in an unregulated gray area, which makes users somewhat hesitant to discuss their regimens. But I did speak to several people who told tales of increased productivity and sharpened focus. Bob Carter, a financial analyst for a start-up called LendingHome, says that nootropics have replaced his other morning stimulant. “I basically think of it as a substitute for coffee,” he says. “I think the problem with a cappuccino from Starbucks is that it gives you the feeling of being jittery. Whereas with this particular supplement, I feel more calm.”
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.
One claim was partially verified in passing by Eliezer Yudkowsky (Supplementing potassium (citrate) hasn’t helped me much, but works dramatically for Anna, Kevin, and Vassar…About the same as drinking a cup of coffee - i.e., it works as a perker-upper, somehow. I’m not sure, since it doesn’t do anything for me except possibly mitigate foot cramps.)
(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%.
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 easiest way to use 2mg was to use half a gum; I tried not chewing it but just holding it in my cheek. The first night I tried, this seemed to work well for motivation; I knocked off a few long-standing to-do items. Subsequently, I began using it for writing, where it has been similarly useful. One difficult night, I wound up using the other half (for a total of 4mg over ~5 hours), and it worked but gave me a fairly mild headache and a faint sensation of nausea; these may have been due to forgetting to eat dinner, but this still indicates 3mg should probably be my personal ceiling until and unless tolerance to lower doses sets in.
Since the discovery of the effect of nootropics on memory and focus, the number of products on the market has increased exponentially. The ingredients used in a supplement can tell you about the effectiveness of the product. Brain enhancement pills that produce the greatest benefit are formulated with natural vitamins and substances, rather than caffeine and synthetic ingredients. In addition to better results, natural supplements are less likely to produce side effects, compared with drugs formulated with chemical ingredients.
