What the Label Data Shows

GastroCort II is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 8 ingredients from Allergy Research Group, sold in capsule form. These ingredients span 4 nutrient categories, non-nutrient/non-botanical, amino acid, other, vitamin, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 8-ingredient formula, 8 of 8 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 off-market in the DSLD, with its label first entered into the database on 2013-04-25. Once a product goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
