What the Label Data Shows

Optimal Digestive System is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a non-nutrient/non-botanical supplement built from 13 ingredients from NOW, sold in capsule form. These ingredients span 6 nutrient categories, enzyme, blend, fiber, other, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 13-ingredient formula, 13 of 13 fall outside the FDA's Daily Value system altogether, expected for a broader formula -- the more ingredients a label lists, the more likely it accumulates botanicals, amino acids, or specialty compounds the FDA has never benchmarked.

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 2018-05-24. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
