I have just started to take Fisetin because it is going to make me an (even bigger) genius. But seriously: https://www.selfhacked.com/blog/15-science-based-health-benefits-fisetin-1-favorite/ We shall see, I report back when I smarten up. Fisetin is a fairly new thing and not many studies and data are available on it. Another supplement I have ran into while researching cognitive function helpers was Vinpocetine. On Amazon it gets pretty good reviews and there are some European studies backing up the results. "Because some people think vinpocetine might improve blood flow to the brain, it is used for enhancing memory and preventing Alzheimer’s disease and other conditions that harm learning, memory, and information processing skills as people age. Vinpocetine is also used for preventing and reducing the chance of disability and death from ischemic stroke. This is the type of stroke that occurs when a blood clotstops blood flow in the brain, causing brain cells (neurons) to die because they are not receiving oxygen. People try vinpocetine for preventing and treating stroke right after it happens because they think vinpocetine might help keep blood from clotting and might also protect neurons against the harmful effects of oxygen deprivation." https://www.webmd.com/vitamins/ai/ingredientmono-175/vinpocetine Just one thing at a time, once I finish my Fisetin I probably try Vinpocetine. An Amazon review of the later: " ...before I went to sleep one night, the next morning I woke feeling so...Aware is the best way to describe it. Sharp mentally. It definitely opened up my senses and cleared my mind allowing my thoughts to process more efficiently. Its a subtle but definitely noticeable change. I couldn't say that it's boosting my intelligence but it's definitely making what I got going on work more efficiently "
