The closest I get is I occasionally take creatine. I'm vegetarian, I think the studies go either way on if the low creatine in a veg diet matters for mental acuity or not. I'll take 3g daily for a month, then forget about it, feel like it does nothing, etc. I notice small benefits re: muscle size, but never anything mental.
