How does C-1000 Buffered C compare?
Ingredients listed on each label, against the other combinations category average of 21.8. Data from the NIH DSLD.
C-1000 Buffered C lists 22 ingredients fewer than 1,000 mg Vitamin C Acai Berry. That is 10 below the other combinations average.
What the Label Data Shows
C-1000 Buffered C is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 12 ingredients from NOW, sold in tablet or pill form. These ingredients span 7 nutrient categories, mineral, other, non-nutrient/non-botanical, vitamin, and 3 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 12-ingredient formula, 12 of 12 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.
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 2013-02-25. 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.
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.
