Understanding that nootropics are an efficient way to enhance cognitive health, with the activity of diet and exercise..are there any practitioners on healthtap who support such a regimine? whether by natural or synthetic compounds of nootropics?

No. Don't think so.: If there are any good research studies comparing patients on a brain-enhancing substance vs. patients on a placebo, that show any real-life brain improvements (not outweighed by the substance's side effects), then such a substance might be worthy of consideration. If no good human studies are done, then sales pitches and testimonials have nothing to stand on.

Cognitive enhancemen: I do believe that there are many life style changes and supplements that can enhance brain function. For example, high homocysteine is very harmful to the brain, but if your level is elevated above 10, you can lower it using four vitamins including L-methyfolate, enhanced vitamin B6 and B12 and trimethylglycine. Taking enough omega 3 to get your AA/EPA level between 1 and 3 is very beneficial.
