What the Label Data Shows

100% Pure Krill Oil 500 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a fat/fatty acid supplement built from 9 ingredients from Swanson EFAs, sold in softgel capsule form. These ingredients span 5 nutrient categories, fatty acid, other, fat, non-nutrient/non-botanical, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 9-ingredient formula, 9 of 9 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 off-market in the DSLD, with its label first entered into the database on 2018-08-31. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.

About the DSLD database

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.
