What the Label Data Shows
DAO Histaminase With Bioflavonoids is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a non-nutrient/non-botanical supplement built from 15 ingredients from Allergy Research Group, sold in capsule form. These ingredients span 6 nutrient categories, other, non-nutrient/non-botanical, complex carbohydrate, enzyme, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 15-ingredient formula, 15 of 15 carry no FDA reference-intake value, typical for a formula this size: larger blends tend to pull in botanicals, amino acids, and specialty compounds without an assigned Daily Value. Breadth like this isn't a red flag by itself.
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 2017-10-21. An on-market listing means the product is currently sold in the United States; the DSLD catalogs the label as submitted but does not independently verify the claims or evaluate safety or efficacy.
