What the Label Data Shows

According to NIH DSLD label rows, O2 sits in the top 29% of products with a countable formula by declared ingredient count.

O2 is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a mineral supplement built from 14 ingredients from O2 Worldwide, sold in liquid form. A single-ingredient-group formula like this keeps the label's dosing simple to read.

Across a broader 14-ingredient formula, 14 of 14 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 2023-01-23. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.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.
