What the Label Data Shows

Formula 390 B-Complex is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 14 ingredients from DC, sold in tablet or pill form. These ingredients span 6 nutrient categories, vitamin, mineral, fiber, fatty acid, and 2 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.

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 2021-04-22. Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved.
