Jeanne - Simme Valley said:I won't argue that one way or the other. "As far as I know", can't claim something unless they have paid the research - maybe this is only true for drugs.
A mineral is a supplement and not covered by the FDA or USDA. Neither of those regulates supplements at all (unless they find a drug in them). That is why you can buy all of those "male enhancement" supplements and hair grower's ect.
