Exposure to vanadium is very common, as it is a naturally occurring element that is found in many parts of the environment, including at low levels in many foods. Higher levels of vanadium can be found in seafood and in some nutritional supplements. According to California Office of Environmental Health Hazard Assessment
, people are exposed to an estimated 10 to 60 micrograms of vanadium on a daily basis. Food contributes between 10 to 20 micrograms per day, and a daily vitamin pill also may contribute 10 micrograms per day. Because vanadium
is poorly absorbed from the gastrointestinal tract, it’s unlikely that ingested vanadium absorbed at these daily levels results in any adverse human health effects. Vanadium exposure may also occur to a small degree through the lungs and skin.
