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).
