What the Label Data Shows
L-Tryptophan 1000 mg is a compact, 3-ingredient amino acid/protein supplement from SuperSmart, sold in tablet or pill form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 3 nutrient categories, amino acid, botanical, fiber, reflecting a multi-component formula rather than a single-nutrient product.
With only 3 ingredients on the label, 3 of 3 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.
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 2021-05-22. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
About the DSLD database
The DSLD is a label database, not an FDA approval list, under the 1994 DSHEA framework, dietary supplements do not require pre-market approval, and label information reflects what manufacturers self-declare rather than independent laboratory verification. 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.
