What the Label Data Shows

Harness Key West is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 14 ingredients from Arms Race Nutrition, sold in powder form. These ingredients span 6 nutrient categories, non-nutrient/non-botanical, amino acid, blend, botanical, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 14-ingredient formula, 14 of 14 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 on-market in the DSLD, with its label first entered into the database on 2024-10-24. 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.
