To be honest most vitamines wind up just being expensive urine.I don't believe %99 of what I hear about all these natural cures . Yea, maybe if you started as a child and lived an entire lifetime taking certain grains or herbs or whatever . Then it could possibly help . Thinking that at say 55 you're going to start taking a vitamine or herb or tonic or foodstuff and it's going to ward off cancer is not true. It's a BIG business with bIG hype..No different than the drug business.%99 of all problems are genetic in my opinion anyway.
