Selenium

Vitamins & NutrientsNutrientsBlood

Selenium is one of the trace minerals — the minerals the body needs only in tiny amounts. Vitamins and minerals are micronutrients, substances the body needs in small amounts to work properly. Taken in excess, chromium, manganese or selenium can cause heavy metal poisoning.

Why it matters: Selenium is one of the metals a heavy metal test may less commonly look for. A heavy metal test checks for high levels of toxic or potentially harmful metals in the body, using a blood, urine, hair or fingernail sample, and a provider may order one where there are signs of heavy metal poisoning or a known exposure.
