What the Label Data Shows
Double Strength Zymactive Proteolytic Enzymes is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a non-nutrient/non-botanical supplement built from 9 ingredients from Natural Factors, sold in tablet or pill form. These ingredients span 4 nutrient categories, other, enzyme, blend, fiber, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 9-ingredient formula, 9 of 9 sit outside the FDA's reference-intake system entirely -- common at this scale, since multi-ingredient blends tend to accumulate botanicals, amino acids, and specialty compounds the FDA has never benchmarked. That's expected breadth, not a red flag on its own.
Market status matters for supplement research. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2012-06-01. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
