What the Label Data Shows
Niacinamide 100 is a compact, 4-ingredient non-nutrient/non-botanical supplement from GNC, sold in tablet or pill form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 4 nutrient categories, vitamin, mineral, fiber, botanical, reflecting a multi-component formula rather than a single-nutrient product.
With only 4 ingredients on the label, 4 of 4 sit outside the FDA's reference-intake system, common for a compact label built from botanicals, amino acids, or specialty ingredients that simply don't carry an FDA-set Daily Value benchmark.
Market status matters for supplement research. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2011-10-26. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.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.
