Your comment: I think the calcium is ok but I disagree with the logic - manufacturers use all kinds of unsafe ingredients. Most deoderants use aluminum - linked to alzheimers (females shave armpits absorbing it even more), nutrasweet, etc etc. MY pet peeve is that they allow styrofoam cups - especially hot drinks like coffee release all kinds of toxic cancer stuff from the styrofoam (the worse styofoam cups are the cheap pebbly ones).
Answer: I agree that manufactures use unsafe products, but they may be the Drugs etc !
For ingredients of Vitimans and Minerals they have a Very Strict Code they must follow in the USA and these items are too cheap to make a mistake with, but for the other Junk added, which may be made with artifical items etc and cost a lot, the Drug companies may have paid off those doing the Regulating ?
The Basic food ingredients of Vitamins and Minerals is strictly regulated in the USA !
