There're also: Huperzine-A, Vinpocetine, Phosphatidyl Serine, Phosphatidyl Choline, Ginko, Acetyl-L-Carnitine, Taurine, Magnesium. There's a list of them in the book 'The Brain Trust Program', also Ray Kurzweil's 'Fantastic Voyage'.
I finished a bottle of Huperzine-A a little while ago. Did apparently zilch for me - no subjective effects, no side-effects, no apparent effects on DNB, etc. (It was from Source Naturals, which is apparently reputable enough that I discount the possible of counterfeits.) In comparison, I did notice effects from piracetam, eg., or fish oil (http://groups.google.com/group/brain-training/browse_thread/...).
