What the Label Data Shows
With 19 ingredients on the label, 4 in 1 900 mg Extra Strength is one of the more extensive fat/fatty acid supplement formulas from Schiff MegaRed Advanced in the NIH Dietary Supplement Label Database (DSLD), sold in softgel capsule form. These ingredients span 6 nutrient categories, other, fat, fatty acid, blend, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 19-ingredient formula, 19 of 19 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.
A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2016-09-22. Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved.
