About the DSLD database
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.
