What the Label Data Shows

With 20 ingredients on the label, Magnesium & Calcium is one of the more extensive other combinations supplement formulas from NOW in the NIH Dietary Supplement Label Database (DSLD), sold in tablet or pill form. These ingredients span 7 nutrient categories, mineral, non-nutrient/non-botanical, other, vitamin, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 20-ingredient formula, 20 of 20 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.

A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2013-04-25. 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goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
