What the Label Data Shows

According to NIH DSLD label rows, Amino 21 sits in the top 13% of products with a countable formula by declared ingredient count.

With 22 ingredients on the label, Amino 21 is one of the more extensive amino acid/protein supplement formulas from DaVinci Laboratories Of Vermont in the NIH Dietary Supplement Label Database (DSLD), sold in capsule form. These ingredients span 3 nutrient categories, amino acid, non-nutrient/non-botanical, protein, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 22-ingredient formula, 22 of 22 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 2013-05-24. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.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

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.
