What the Label Data Shows
Protec Acidophilus With FOS is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 11 ingredients from Natural Factors, sold in capsule form. These ingredients span 5 nutrient categories, other, bacteria, fiber, complex carbohydrate, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 11-ingredient formula, 11 of 11 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 on-market in the DSLD, with its label first entered into the database on 2012-06-01. An on-market listing means the product is currently sold in the United States; the DSLD catalogs the label as submitted but does not independently verify the claims or evaluate safety or efficacy.
