What the Label Data Shows

SLO-NIACIN 250 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 7 ingredients from Upsher-Smith Laboratories, sold in tablet or pill form. These ingredients span 4 nutrient categories, other, vitamin, fat, mineral, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 7-ingredient formula, 7 of 7 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 on-market in the DSLD, with its label first entered into the database on 2019-09-24. 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

The DSLD is a label database, not an FDA approval list, under the 1994 DSHEA framework, dietary supplements do not require pre-market approval, and label information reflects what manufacturers self-declare rather than independent laboratory verification. 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.
