What the Label Data Shows

Vitamin C Sustained Release 1000 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a vitamin supplement built from 14 ingredients from Bronson Laboratories, sold in tablet or pill form. These ingredients span 6 nutrient categories, other, mineral, fat, vitamin, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 14-ingredient formula, 14 of 14 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 2012-04-26. 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production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.

About the DSLD database

This page presents factual label data for reference only and is not medical advice; consult a licensed healthcare provider before making decisions about any supplement.
