According to NIH DSLD label rows, L-Methionine sits in the top 84% of products with a countable formula by declared ingredient count.

L-Methionine is a compact, 4-ingredient amino acid/protein supplement from NutriCology, sold in capsule form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 2 nutrient categories, amino acid, other, reflecting a multi-component formula rather than a single-nutrient product.

With only 4 ingredients on the label, 4 of 4 lack a reported percentage Daily Value in the source record, so their regulatory reference status remains unspecified here.

Availability status shapes how this label record is best used. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2019-01-07. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.

About the DSLD database

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.
