What the Label Data Shows
Evening Primrose Oil 500 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a fat/fatty acid supplement built from 6 ingredients from Basic Vitamins, sold in softgel capsule form. These ingredients span 4 nutrient categories, fatty acid, other, fat, protein, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 6-ingredient formula, 6 of 6 fall outside the FDA's Daily Value system altogether, expected for a broader formula -- the more ingredients a label lists, the more likely it accumulates botanicals, amino acids, or specialty compounds the FDA has never benchmarked.
Market status matters for supplement research. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2021-06-23. 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.
