Minerals (1 Biomarker)

Selenium is an essential trace element with important functions throughout the body including aiding the synthesis and metabolism of thyroid hormones, strengthening the immune system and in DNA synthesis. Selenium is found in many foods but has highest quantities in brazil nuts, seafood, kidney and meat. Selenium deficiency symptoms include weakness, dizziness, hair loss and nausea. Although selenium is required in the body, exposure to high levels can cause adverse health effects. Toxicity may occur following over-ingestion of supplements/foods or through occupational exposure.
