Parent Ingredient
L-Selenomethionine
Selenium is an essential trace element required for selenoproteins including glutathione peroxidases and thyroid-hormone deiodinases. Selenomethionine raises selenium status more effectively per microgram than inorganic selenite, though selenium nutrition follows a U-shaped curve — both deficiency and excess are harmful.
