No evidence: I am not aware of studies showing such an association. Even so, use all supplements in moderation.

Who knows: since no body knows what's in them. One thing is known, however, and that is that they're all a waste of money and won't help you in any way. Don't get your medical information from friend, tv or internet scams.
