What the Label Data Shows
According to NIH DSLD label rows, IsoStak sits in the top 19% of products with a countable formula by declared ingredient count.
With 18 ingredients on the label, IsoStak is one of the more extensive other combinations supplement formulas from Universal Nutrition in the NIH Dietary Supplement Label Database (DSLD), sold in capsule form. These ingredients span 6 nutrient categories, non-nutrient/non-botanical, vitamin, botanical, mineral, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 18-ingredient formula, 18 of 18 do not carry a reported percentage Daily Value in the source record. That missing field does not establish whether an FDA reference value exists.
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 2011-12-23. Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved.
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.
