cooked-meat-with-vegetables-725991Selenium is an essential trace element that is important for many bodily processes, including hormone production, a healthy immune system, and fertility in both men and women.

Selenium is an antioxidant, and helps protect your cell’s DNA from damage caused by oxidation. For athletes, selenium can improve healing after injuries and, when combined with vitamin C and vitamin E, help muscles recover after strenuous exercise.

Selenium is found in meat, fish, poultry, and eggs. Vegetarian sources include Brazil nuts and whole grains. Selenium deficiency is rare, but overconsumption is common among individuals whole use multivitamin supplements.

Your DNA affects how you metabolize selenium.

The SEPP1 gene codes for a protein that carries and transports selenium throughout your body. Selenoproteins account for most of the selenium present in plasma and are often used to measure selenium levels. Variants of this gene can affect the serum selenium levels.

The recommended daily selenium intake for adults is 55 mcg/day, but some athletes can benefit from up to 200 mcg/day. However, ensure that you do not consume more than 400 mcg/day. Understanding how your genetics affect your selenium metabolism will help you keep the right levels.
