What the Label Data Shows

Glucosamine plus Extra Strength is a compact, 4-ingredient non-nutrient/non-botanical supplement from Douglas Laboratories, sold in capsule form, cataloged in the NIH Dietary Supplement Label Database (DSLD). These ingredients span 3 nutrient categories, non-nutrient/non-botanical, other, vitamin, reflecting a multi-component formula rather than a single-nutrient product.

With only 4 ingredients on the label, 4 of 4 fall outside the FDA's reference-intake system -- a tight formula built mostly from botanicals, amino acids, or specialty compounds without a set Daily Value benchmark, which is routine for a focused label like this one.

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 2022-02-23. 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.
