Mike,
I just checked my vitamin packs. I take a premade pack sold by Costco. I think it is called High Energy. It used to have ginko biloba. Now it just has Asian Ginseng 100mg for mental alertness. .
I also add 10 other pieces to the 7 piece Costco pack.
You might find this web site interesting. It looks at issues from a scientific basis with the only bias being a serious concern for the risk factors of genetic modifications.

Truth is hard to fight when there is a scientific understanding. Knee jerk reactions because of political biases often do not stand up to scientific scrutiny.
