Dotsie, simply ask Gregory Ann. She is a fountain of info and got me started on a good vitamin routine. Now if I miss them, I can tell it. CO-Q10 seems to be one that she says is a must have, too. I take fish oil, but haven't noticed any after taste. Vitamin E, and a few others. I also use Puritan Pride for ordering. They have the best deals to me, and Gregory says their stuff contains exactly what they say it does.
