There is no RDA, but a suggested intake is about 20 mcg. High levels are toxic.	Toxicity with vanadium is associated with manic depression and supplements should not be taken unless under strict supervision.	Vanadium is involved in many processes but is little understood.	Vanadium is present in whole grains, nuts, root vegetables, liver fish, and is high in lobster and parsley.
