What the Label Data Shows
L-Carnitine 500 is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a non-nutrient/non-botanical supplement built from 6 ingredients from Progressive Professional from Progressive Laboratories, sold in capsule form. These ingredients span 5 nutrient categories, mineral, non-nutrient/non-botanical, protein, complex carbohydrate, and 1 more, 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.
