Selenium is an essential trace mineral that is important for many different functions in the body. It is required for the proper functioning of the immune system, and it plays a role in thyroid hormone metabolism, DNA synthesis, and antioxidant defense. Here are just a few of the potential benefits of selenium:
- May support immune health
Selenium plays a vital role in immune function and is necessary for the production of antibodies, which help to protect against infections. Some research suggests that increasing selenium intake may help to improve immune function and reduce the risk of infections.
- May support thyroid health
Selenium is necessary for the proper metabolism of thyroid hormones, which are important for maintaining normal metabolism and energy levels. Some research suggests that increasing selenium intake may help to improve thyroid function and reduce the risk of certain thyroid conditions, such as autoimmune thyroiditis.
- May have antioxidant effects
Selenium is a powerful antioxidant that helps to protect cells from oxidative stress, which is caused by an imbalance of antioxidants and free radicals in the body. Oxidative stress has been linked to a variety of health problems, including heart disease, cancer, and age-related conditions.
- May improve fertility
Some research suggests that increasing selenium intake may help to improve fertility in both men and women. In men, selenium may help to improve sperm quality and motility. In women, it may help to reduce the risk of miscarriage and improve the chances of successful in vitro fertilization (IVF).
- May reduce the risk of certain cancers
Some research suggests that increasing selenium intake may help to reduce the risk of certain types of cancer, including prostate, lung, and colorectal cancer. However, more research is needed to fully understand the potential anti-cancer effects of selenium.
Overall, selenium is an essential trace mineral that is important for many different functions in the body. Ensuring that you get enough selenium in your diet may have a variety of potential health benefits. Good sources of selenium include nuts, seeds, whole grains, and seafood.
