What the Label Data Shows
L-Carnitine 500 Tabs is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a non-nutrient/non-botanical supplement built from 8 ingredients from ON Optimum Nutrition, sold in tablet or pill form. These ingredients span 4 nutrient categories, mineral, other, non-nutrient/non-botanical, fatty acid, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 8-ingredient formula, 8 of 8 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.
Availability status shapes how this label record is best used. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2016-03-24. This product is actively distributed in the U.S. right now. As with every DSLD entry, that listing reflects the manufacturer's self-declared label, not an independent safety or efficacy review.
