What the Label Data Shows

Niacin-SR 500 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 6 ingredients from Klaire Labs, sold in tablet or pill form. These ingredients span 5 nutrient categories, mineral, vitamin, fatty acid, fiber, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 6-ingredient formula, 6 of 6 sit outside the FDA's reference-intake system entirely -- common at this scale, since multi-ingredient blends tend to accumulate botanicals, amino acids, and specialty compounds the FDA has never benchmarked. That's expected breadth, not a red flag on its own.

Availability status shapes how this label record is best used. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2022-05-19. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.

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.
