What the Label Data Shows

According to NIH DSLD label rows, Cal-6-Forte sits in the top 47% of products with a countable formula by declared ingredient count.

Cal-6-Forte is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a other combinations supplement built from 9 ingredients from Douglas Laboratories, sold in tablet or pill form. These ingredients span 5 nutrient categories, mineral, vitamin, amino acid, fiber, and 1 more, reflecting a multi-component formula rather than a single-nutrient product.

Across a broader 9-ingredient formula, 9 of 9 have no percentage Daily Value reported in this DSLD source record, so the available data cannot establish their FDA reference status.

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 2012-02-23. Once a product goes off-market, it is no longer manufactured or sold under this label, yet the DSLD keeps the record intact for historical reference, useful for researchers, anyone with an older bottle on hand, or tracking how formulations changed over time.
