Recommended Dose of Selenium For Athletes
Dose: 200 mcg per day
Why Should Athletes Supplement With Selenium?
- Selenium is a mineral that has antioxidant properties and may help protect cells from damage.
- Selenium is a trace element that is naturally present in many foods, added to others, and available as a dietary supplement.
- Selenium is nutritionally essential for humans!
- It has more than two dozen selenoproteins that play critical roles in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection
- Some health conditions — such as HIV, Crohn’s disease, and others — are associated with low selenium levels. There is evidence that selenium supplements may reduce the odds of prostate cancer.
- Selenium is required for the proper activity of a group of enzymes collectively called glutathione peroxidase. These enzymes each help turn toxic hydrogen peroxide into harmless water.
- Of the eight known glutathione peroxidase enzymes, five of them require selenium.
- In addition to the activity of glutathione peroxidase, selenium-containing enzymes are involved in recycling of vitamin C from its spent form back to its active one, allowing for greater antioxidant protection.
- Seafood and organ meats are the richest food sources of selenium. Other sources include muscle meats, cereals and other grains, and dairy products.
- The amount of selenium in drinking water is not nutritionally significant in most geographic regions.
- The major food sources of selenium in the American diet are breads, grains, meat, poultry, fish, and eggs.
- In parts of the world where diets are low in selenium, health problems routinely occur due to poor antioxidant protection. Animal studies suggest that as little as two weeks without dietary selenium sources can lead to disruptions in protection against free radicals.
