Concentration & Memory Concentration, Memory

Does anyone use anything for alertness/concentration, etc?  Know of anything that works quickly? - without hyperness of course.  I just started taking Memory+.  It is power packed with mind boosters:  Ashwaghanda, Bacopa, Gotu kola, Gingko biloba, Sib. ginseng.  I already take full spectrum vit. E with my fish oil.  I figure the Memory+ will be beneficial over the longterm, but wonder if it helps in a week or two as well.

I have been researching phosphatidylersine (soybeans) for the increase in memory function.  Helps with older people.  does anyone have any information on this?

I take Ginkgo Biloba, It works 'great' and very fast, I notice a difference in two or three days.Also omega3, and i eat lots of walnuts, salmon, foods that are good for brain function.Hope this helps.
