SeleniumSelenium is a free radical-scavenging nutrient that is concentrated in the lining of the GI tract and lungs, in the liver, and in skeletal muscle. It is essential to the production of antioxidant glutathione peroxidase (SeGPx). In an animal study, reducing muscular SeGPx increased cellular damage from prolonged exercise, supporting the theory that free radical-induced muscle damage causes muscle fatigue.11Research shows selenium benefits athletes' immune function and helps repair cellular damage. Researchers studied the selenium supplementation effects on muscle SeGPx in 24 healthy nonsmoking males. Half took 240 mcg of sodium selenite; half took placebo. After cycling to exhaustion-durations ranged from 2.6 to 3.5 hours-the group that took selenium showed less cellular damage.12 Supplementation with 200 mcg of selenium is safe and warranted for endurance athletes.13 |
