What the Label Data Shows

According to NIH DSLD label rows, Fish Oil 500 mg sits in the top 58% of products with a countable formula by declared ingredient count.

Fish Oil 500 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a fat/fatty acid supplement built from 7 ingredients from Major, sold in softgel capsule form. These ingredients span 5 nutrient categories, fatty acid, other, fat, protein, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 7-ingredient formula, 7 of 7 have no percentage Daily Value reported in this DSLD source record, so the available data cannot establish their FDA reference status.

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 2019-04-25. An on-market listing means the product is currently sold in the United States; the DSLD catalogs the label as submitted but does not independently verify the 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.
