What the Label Data Shows

Flush-Free Niacin 250 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 10 ingredients from NOW, sold in capsule form. These ingredients span 7 nutrient categories, non-nutrient/non-botanical, other, fiber, vitamin, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 10-ingredient formula, 10 of 10 fall outside the FDA's Daily Value system altogether, expected for a broader formula -- the more ingredients a label lists, the more likely it accumulates botanicals, amino acids, or specialty compounds the FDA has never benchmarked.

A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2012-10-25. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.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.
