What the Label Data Shows
Mega Strength Beta Sitosterol 375 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a fat/fatty acid supplement built from 10 ingredients from Source Naturals, sold in tablet or pill form. These ingredients span 5 nutrient categories, mineral, fat, other, blend, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 10-ingredient formula, 10 of 10 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.
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 2019-10-23. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
About the DSLD database

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.
