What the Label Data Shows

L-Arginine 500 mg is a compact, 2-ingredient amino acid/protein supplement from Intensive Nutrition, sold in capsule form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 2 nutrient categories, amino acid, other, reflecting a multi-component formula rather than a single-nutrient product.

With only 2 ingredients on the label, 2 of 2 fall outside the FDA's reference-intake system -- a tight formula built mostly from botanicals, amino acids, or specialty compounds without a set Daily Value benchmark, which is routine for a focused label like this one.

A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2013-07-25. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
