Linking to a huge list of supplement guidelines, most of which cover labeling of nutrient content is not helpful. I did try to dig in, however, and found this:

> A qualified health claim is supported by less scientific evidence than an authorized health claim. FDA requires that qualified claims be accompanied by a disclaimer that explains the level of the scientific evidence supporting the relationship.

> Unlike authorized health claims, FDA does not issue regulations for qualified health claims.

That does seem to indicate supplement manufacturers have broad latitude to make claims provided they are disclosed as such.
