What the Label Data Shows

Calcium Carbonate is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a mineral supplement from NOW, sold in powder form. The label declares 2 ingredients. These ingredients span 2 nutrient categories, mineral, other, reflecting a multi-component formula rather than a single-nutrient product.

Daily Value coverage on this label is informative. No ingredients on this label reach 100% of the FDA reference Daily Value, 0 fall below 100% DV, and 2 have no FDA-established Daily Value reference.. Some nutrients (such as botanicals, amino acids, and specialty compounds) have no Daily Value because the FDA has not set a reference intake; absence of a DV is neither good nor bad on its own.

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 2017-06-23. Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved. The DSLD is a label database, not an FDA approval list, under the 1994 DSHEA framework, dietary supplements do not require pre-market approval, and label information reflects what manufacturers self-declare rather than independent laboratory verification.
