What the Label Data Shows

With 33 ingredients on the label, Mega Antioxidant is one of the more extensive other combinations supplement formulas from USANA in the NIH Dietary Supplement Label Database (DSLD), sold in tablet or pill form. These ingredients span 7 nutrient categories, vitamin, non-nutrient/non-botanical, other, botanical, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 33-ingredient formula, 33 of 33 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.

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 2012-12-21. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.
