I agree with your point in general, but doesn't that disclaimer apply to any kind of supplement? As far as I know that sort of thing has been allowed for quite some time. For whatever reason the FDA allows for an almost completely unregulated vitamin/supplement industry.

They used to be vague and not make specific claims because that wasn't allowed. They'd say "Vitamin K helps promote healthy eyes." They can't say "our chewable will cure your glaucoma. (claimhasnotbeenreviewedbytheFDA)"

But apparently they can do that now, or at least they are doing it.

It's not up to the FDA, their hands are tied thanks to the Dietary Supplement Health and Education Act of 1994, sponsored by Senator Orrin Hatch from Utah on behalf of the supplement lobby.
