What the Label Data Shows

Mega Primrose is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a fat/fatty acid supplement built from 13 ingredients from Source Naturals, sold in softgel capsule form. These ingredients span 4 nutrient categories, other, fat, fatty acid, protein, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 13-ingredient formula, 13 of 13 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.

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 2020-02-26. 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.
