What the Label Data Shows
According to NIH DSLD label rows, 3-in-1 Joint Formula sits in the top 8% of products with a countable formula by declared ingredient count.
With 28 ingredients on the label, 3-in-1 Joint Formula is one of the more extensive other combinations supplement formulas from Irwin Naturals in the NIH Dietary Supplement Label Database (DSLD), sold in softgel capsule form. These ingredients span 10 nutrient categories, botanical, vitamin, non-nutrient/non-botanical, fat, and 6 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 28-ingredient formula, 28 of 28 do not carry a reported percentage Daily Value in the source record. That missing field does not establish whether an FDA reference value exists.
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 2011-11-25. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.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.
