Interactions
synergistic. Selenium-dependent glutathione peroxidase and vitamin E are complementary lipid antioxidants; selenium reduces lipid hydroperoxides while vitamin E prevents their formation
synergistic. Selenium is required for deiodinase enzymes that convert T4 to active T3; selenium also protects thyroid from H2O2 damage during iodine-dependent hormone synthesis
competes. Very high-dose vitamin C (>1g simultaneously) can reduce selenite to elemental selenium in the GI tract, decreasing absorption; does not affect selenomethionine
competes. Selenium may reduce chemotherapy efficacy by protecting cancer cells from oxidative damage; conversely, it may reduce side effects in normal tissues
