No ingredients on this label reach 100% of the FDA reference Daily Value, 0 fall below 100% DV, and 22 have no FDA-established Daily Value reference..

Market status matters for supplement research. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2012-02-23. 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. The DSLD is a label database, not an FDA approval list, under the 1994 DSHEA framework, dietary supplements do not require pre-market approval, and label information reflects what manufacturers self-declare rather than independent laboratory verification. This page presents factual label data for reference only and is not medical advice; consult a licensed healthcare provider before making decisions about any supplement.
