What the Label Data Shows

Methyl B-12 Rx is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 8 ingredients from NuMedica, sold in lozenge form. These ingredients span 6 nutrient categories, non-nutrient/non-botanical, other, vitamin, sugar, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 8-ingredient formula, 8 of 8 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.

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 2018-08-31. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.
