University College London are running a short (15 min) online study to investigate differences in thinking abilities when on CR. This study has been preliminarily vetted by CR Society VP for Research. We are aware that there is a lot of data to support the link between CR and benefits to health, but there is currently little known about the impact of CR on cognition, particularly executive function. We are comparing the results of those on a popular intermittent fasting (IF) plan (5:2) with those who have daily CR lifestyles to see if there is a difference. Our hypothesis is that those on daily CR will with have better results for certain tests relating to executive function, when compared to those on IF. We intend to publish the results next year and we believe this will be of enormous value both to the scientific community, and to anyone who is considering their options for ways in which to improve their health. Anyone who contacts us will be sent the participant information sheet and a consent form to return before they receive a link to 5 short online tasks. All data is protected and confidential ID numbers used to further protect our participants. This study has passed rigorous ethics procedures.

I was surprised to find that a search of these forums turned up very little discussion of nootropics, or so-called "smart drugs", at least as far as I could find. Obviously cognitive performance and long-term brain health is an important consideration for everyone, but especially obsessive optimizers like us ☺. So I figured I'd start a thread to inquire if anyone has experimented with nootropics, and if so, which ones (if any) did you find beneficial. To kick off the discussion, I've never experimented with any nootropics myself, except for caffeine, which honestly I don't find has much of an observable effect on me (cognitive or otherwise), but I take it anyway (as coffee/tea, and as a B12-fortified mint) for other health reasons. But today I came across a new multi-nootropic supplement from someone I trust, respect and believe to be quite intelligent - Lincoln Cannon. Lincoln is the co-founder of the Mormon Transhumanism Association, a pretty cool longevity-focused organization to which I and many other non-Mormons belong. Lincoln is also responsible for formulating the New God Argument, which I find pretty compelling (see here for related discussion and here for science/philosophy heavyweights on the topic). But I digress... Thrivous, his new company (to which I have no affiliation), has developed a nootropic supplement called Clarity. Here is the Clarity label: Has anyone any personal experience, or done any research on any of these ingredients? Here is Lincoln's research on them, plus a couple others not included in this version of Clarity. They look reasonably beneficial (and harmless) based on the controlled studies Lincoln has compiled. The price is pretty reasonable - $25 for a month's supply. I'm forever interested in self-experimentation and lifestyle optimization, so I was thinking of conducting a single-blind, crossover trial on myself to see if I notice any difference between taking Clarity vs. a placebo. But if others have had bad experiences with these nootropics, or know of research that says they may be harmful, I'll obviously steer clear. Thanks! --Dean
