What the Label Data Shows

With 16 ingredients on the label, Metabolic Advantage Thyroid Formula is one of the more extensive other combinations supplement formulas from Enzymatic Therapy in the NIH Dietary Supplement Label Database (DSLD), sold in capsule form. These ingredients span 7 nutrient categories, mineral, other, vitamin, amino acid, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 16-ingredient formula, 16 of 16 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 2013-09-25. 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.
