No ingredients on this label reach 100% of the FDA reference Daily Value, 0 fall below 100% DV, and 44 have no FDA-established Daily Value reference..

Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved.
