What the Label Data Shows
Histamine Block Plus is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement from Seeking Health, sold in capsule form. The label declares 19 ingredients. These ingredients span 6 nutrient categories, vitamin, mineral, non-nutrient/non-botanical, other, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Daily Value coverage on this label is informative. No ingredients on this label reach 100% of the FDA reference Daily Value, 0 fall below 100% DV, and 19 have no FDA-established Daily Value reference.. Some nutrients (such as botanicals, amino acids, and specialty compounds) have no Daily Value because the FDA has not set a reference intake; absence of a DV is neither good nor bad on its own.
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 2025-02-23. On-market products are currently being distributed in the United States, though the DSLD does not verify the accuracy of label claims or evaluate safety or efficacy.
