What the Label Data Shows
According to NIH DSLD label rows, Optimized Tryptophan Plus sits in the top 32% of products with a countable formula by declared ingredient count.
Optimized Tryptophan Plus is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a botanical with nutrients supplement built from 13 ingredients from Life Extension, sold in capsule form. These ingredients span 9 nutrient categories, vitamin, amino acid, botanical, other, and 5 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 13-ingredient formula, 13 of 13 have no percentage Daily Value reported in this DSLD source record, so the available data cannot establish their FDA reference status.
A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2016-07-25. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.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.
