What the Label Data Shows

AlphaSorb-C 500 is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 14 ingredients from NOW, sold in capsule form. These ingredients span 7 nutrient categories, non-nutrient/non-botanical, other, mineral, blend, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 14-ingredient formula, 14 of 14 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 2024-07-25. 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.
