What the Label Data Shows
B-12 Sublingual Liquid is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 9 ingredients from Swanson Premium Brand, sold in liquid form. These ingredients span 4 nutrient categories, other, vitamin, non-nutrient/non-botanical, blend, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 9-ingredient formula, 9 of 9 carry no FDA reference-intake value, typical for a formula this size: larger blends tend to pull in botanicals, amino acids, and specialty compounds without an assigned Daily Value. Breadth like this isn't a red flag by itself.
