What the Label Data Shows

With 16 ingredients on the label, Stress B with Iron is one of the more extensive multi-vitamin and mineral (mvm) supplement formulas from 21st Century in the NIH Dietary Supplement Label Database (DSLD), sold in tablet or pill form. These ingredients span 5 nutrient categories, vitamin, mineral, complex carbohydrate, other, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 16-ingredient formula, 16 of 16 have no percentage Daily Value reported in this DSLD source record, so the available data cannot establish their FDA reference status.

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 2019-08-23. 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.
