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.

Mustard sprout. The greens and seeds of the Indian, or brown mustard plant, Brassica juncea, have been cultivated in Asia and Europe for thousands of years 2.

The sprouts can then be used in dietary supplements as sources of essential and trace minerals such as chromium, iron, manganese, selenium and zinc 3.
