What the Label Data Shows
L-Citrulline 1200 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a amino acid/protein supplement built from 6 ingredients from NOW Sports, sold in tablet or pill form. These ingredients span 4 nutrient categories, other, amino acid, fatty acid, mineral, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 6-ingredient formula, 6 of 6 carry no FDA reference-intake value, typical for a formula this size: larger blends tend to pull in botanicals, amino acids, and specialty compounds without an assigned Daily Value. Breadth like this isn't a red flag by itself.
