What the Label Data Shows

According to NIH DSLD label rows, Concentrated Soy Isoflavones sits in the top 65% of products with a countable formula by declared ingredient count.

Concentrated Soy Isoflavones is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 6 ingredients from Sundown Naturals, sold in tablet or pill form.

This product is actively distributed in the U.S. right now. As with every DSLD entry, that listing reflects the manufacturer's self-declared label, not an independent safety or efficacy review.

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.
