What the Label Data Shows
L-Arginine 500 mg is a compact, 4-ingredient amino acid/protein supplement from PhysioLogics, sold in capsule form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 3 nutrient categories, fiber, amino acid, other, reflecting a multi-component formula rather than a single-nutrient product.
With only 4 ingredients on the label, 4 of 4 have no FDA reference-intake value at all, unremarkable on a short ingredient list drawn from botanicals, amino acids, or other specialty compounds the FDA has never assigned a Daily Value to.
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 2011-12-23. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.
About the DSLD database

This page presents factual label data for reference only and is not medical advice; consult a licensed healthcare provider before making decisions about any supplement.
