What the Label Data Shows

With 22 ingredients on the label, Longer Stronger Hair & Nails is one of the more extensive other combinations supplement formulas from Applied Nutrition in the NIH Dietary Supplement Label Database (DSLD), sold in softgel capsule form. These ingredients span 9 nutrient categories, vitamin, mineral, botanical, other, and 5 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 22-ingredient formula, 22 of 22 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.

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 2012-10-01. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
