What the Label Data Shows

Buffered C-1000 Complex is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 14 ingredients from NOW, sold in tablet or pill form. These ingredients span 7 nutrient categories, mineral, other, non-nutrient/non-botanical, fatty acid, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 14-ingredient formula, 14 of 14 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.

Market status matters for supplement research. This product is currently listed as on-market in the DSLD, with its label first entered into the database on 2024-06-20. An on-market listing means the product is currently sold in the United States; the DSLD catalogs the label as submitted but does not independently verify the claims or evaluate safety or efficacy.
