I take Ginko just for the hellufit...don't feel any different if I do or don't take it. I also take Evening Primrose but that too seems not to have any effect, at least that I can discern. I take fish oil and flax oil capsuls (took them before I went on Adderall) for lowering my cholesterol(which it did!)--some say the fish oil should help the brain functions and perhaps it does, but again...nothing that I've noticed.
