In recent years, the interest of the relationship between microelement and human health increased. Vanadium is an essential trace element for animal and man. Vanadium absence may have negative effects, and it also can be toxic if exposure occurs at high enough levels. The toxicity of vanadium depends on its total content, oxidation states and existence speciation. So in this paper, the biological effect of vanadium, the source of vanadium and existence states (oxidation state and speciation) were summarized.
