What the Label Data Shows
Quercetin 500 Plus is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 7 ingredients from Newflower Farmers Markets, sold in tablet or pill form. These ingredients span 6 nutrient categories, non-nutrient/non-botanical, vitamin, mineral, enzyme, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 7-ingredient formula, 7 of 7 carry no FDA reference-intake value, typical for a formula this size: larger blends tend to pull in botanicals, amino acids, and specialty compounds without an assigned Daily Value. Breadth like this isn't a red flag by itself.
A product's market status is worth checking before relying on this label. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2013-01-25. 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

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.
