What the Label Data Shows
Magnesium Optimizer is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 9 ingredients from Jarrow Formulas, sold in tablet or pill form. These ingredients span 5 nutrient categories, mineral, other, non-nutrient/non-botanical, fiber, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 9-ingredient formula, 9 of 9 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.
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 2012-04-26. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.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.
