Vanadium (as vanadyl glycinate)

Vanadium is a trace element found in foods such as mushrooms, shellfish, black pepper, parsley, grains and grain products. The absorption of ingested vanadium is less than 5 percent 1.

A biological role of vanadium in humans is unclear. Therefore, neither a Reference Daily Intake (RDI) nor a Daily Reference Value (DRV) has been set by the U.S. Food and Drug Administration (FDA).

Vanadyl glycinate, or vanadium glycinate, is a form of chelated vanadium, in which a vanadium ion is bound to the amino acid glycine. It is used as a source of the trace mineral vanadium in dietary supplements.

This ingredient can be found in the following products in United States:
