Selenium

 

Selenium is a mineral found in the soil. It naturally appears in water and some foods. While people only need a very small amount, selenium plays a key role in their metabolism.

Benefits

Cognitive Support: Research shows selenium’s antioxidant properties fight cell damage that may worsen brain and nervous system diseases like Parkinson’s, Alzheimer’s, and multiple sclerosis. Scientists believe getting enough in your diet can help maintain healthy brain function.

Anti-Cancer: Its ability to protect against DNA damage and oxidative stress, boost your immune system, and destroy cancer cells. A review of 69 studies that included over 350,000 people found that having a high blood level of selenium was associated with a lower risk of certain types of cancer, including breast, lung, colon, and prostate cancers.

Healthy Heart: In an analysis of 25 observational studies, a 50% increase in blood selenium levels was associated with a 24% reduction in the risk of heart disease. Selenium may also lower markers of inflammation in your body⁠ — one of the main risk factors for heart disease. A review of 16 controlled studies including over 433,000 people with heart disease showed that taking selenium supplements decreased levels of the inflammatory marker C-reactive protein (CRP).

Thyroid Health: Selenium is important for the proper functioning of your thyroid gland. In fact, thyroid tissue contains a higher amount of selenium than any other organ in the human body. This powerful mineral helps protect the thyroid against oxidative damage and plays an essential role in the production of thyroid hormones. A healthy thyroid gland is important, as it regulates your metabolism and controls growth and development.

However, it is important to remember that the maximum amount of Selenium for the average adult is 400 mcg per day.
