What the Label Data Shows

According to NIH DSLD label rows, Formula 390 B-Complex sits in the top 29% of products with a countable formula by declared ingredient count.

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 do not carry a reported percentage Daily Value in the source record. That missing field does not establish whether an FDA reference value exists.

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.

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.
