What the Label Data Shows

According to NIH DSLD label rows, B-50 Powder sits in the top 35% of products with a countable formula by declared ingredient count.

B-50 Powder is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 12 ingredients from NOW, sold in powder form. These ingredients span 3 nutrient categories, vitamin, non-nutrient/non-botanical, botanical, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 12-ingredient formula, 12 of 12 do not carry a reported percentage Daily Value in the source record. That missing field does not establish whether an FDA reference value exists.

A product's market status is worth checking before relying on this label. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2012-12-21. On-market products are currently being distributed in the United States, though the DSLD does not verify the accuracy of label claims or evaluate safety or efficacy.

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.
