Thanx Ka3ryn, One more question, if my body didnt react well to the l-carnitine how would I know? Would there possibly be some reactions that you know of? I believe my vit. has all of those in it,si I should be good to go? The lady at the healthfood store said that women need extra pottas,calci,and magnes, I currently take the pottas supplement, are the others needed like she said? Just want to make sure need more than one opinion, I dont want to give my body something it doesnt need that could be harmful. Sabrina
