    Lifestyle, not age, rules cognitive function...

    ...whether you are 18 or 80. Yes, I know it is hard to believe this statement but that is the conclusion of the study after examining the link between lifestyle (and environment) and cognitive function in a group of people with ages spanning the 18-89 years interval. The conclusion of the study...

    Pregnenolone (P5) improves recovery from stroke

    One of the few direct studies with P5 in-vivo, though that may be changing as I noticed the rate of articles on P5 has been rising over the last 5-6 years. This study used four (4) administrations of P5, at a HED of just 0.3mg/kg, 1, 6, 12, and 18 hours after the (ischemic) stroke was caused...

    Exercise brain-boost may be due simply to increasing brain selenium levels

    Yet another study demonstrating that many of the "mysterious" benefits of exercise most likely have nothing to do with the (insignificant) amount of extra calories burned, but are due to peripheral effects related to metabolism and redox balance. Namely, the study below investigates the...

    Lion’s Mane vs. Methylene Blue

    I’d love to know peoples’ thoughts on how Lion’s mane mushroom & methylene blue compare. From what I understand, both are useful for improved mental clarity, memory, and they have potential in cases of Alzheimer’s. I just ordered some methylene blue, and am curious/excited to experiment with...

    AlloP - Liquid Allopregnanolone For Lab/R&D

    Just a quick announcement that we have replaced the 5α-DHP in our store with allopregnanolone. The main reason for switching over to allopregnanolone is that we always wanted to provide that steroid right from the start, however we could not find a lab willing to synthesize it. Thus, 5α-DHP...

    Air pollution impairs cognition, aspirin is protective

    A new study demonstrating that even short-term (less than a month) exposure to polluted air impaired cognition in humans, and that the mechanism of action was by triggering an inflammatory response. Ergo, anti-inflammatory drugs (NSAID) and especially aspirin, were found to be protective. Since...

    The biggest missing links to optimal brain function – part 1

    What inspired me to write this article is overall reductionism when it comes to mental function. Far too many people want to focus on specific neurotransmitters and blame certain ones for certain conditions (e.g. low dopamine in anhedonia), but health as a whole started to deteriorate first, and...

    Why Intermittent Fasting Actually Works (it’s Not What You Think)

    Intermittent fasting is still somewhat of a hot topic as it does give some people benefits (temporary and some long term). I think one of the most reasons why it works is often overlooked because a lot of people are unaware of it. I want to bring awareness to this reason and also to the fact...

    Blocking Serotonin, Adrenaline Treats Anxiety, Brain Damage Due To Alcohol "addiction"

    Over the last 2 decades a large number of studies have come out demonstrating that the withdrawal symptoms in "addicts" are due largely due to elevated serotonin and adrenaline. As such, drugs such as cyproheptadine, clonidine, propranolol, etc have been successfully used off-label for treating...

    Taurine May Treat Depression And Psychosis In Humans

    A human study, and as such very relevant. The dose (4g daily for 12 weeks) was a bit on the high end but that was probably because the scientists designing the trial were unaware of the studies showing benefits of taurine plateau after 2g daily. In any event, good news for those with mood/mental...

    Pregnenolone Activates The Glycine Receptor

    This mechanism of pregnenolone is one of the proposed methods through which it enhances neurogenesis, memory, mood and even motor function. Low doses pregnenolon improve sleep quality and are even mildly sedating, which may also be due to the activation of the glycine receptor. Subunit-specific...

    Pregnenolone May Protect Cognition From Damage By Stress
