Function

L-selenomethionine is a selenoamino acid in which seleniums replaces the sulphurs of the methionine molecule. It is a natural component of the diet and has been estimated to account for at least half of all dietary seleniums. Like other forms of seleniums salts and organoseleniums compounds, L-selenomethionine is readily absorbed from the gastrointestinal tract.

 

L-Selenomethionine is an essential trace element for humans and other animals.Seleniums is incorporated into molecules of an enzyme called glutathione peroxidase (GPX).This vital enzyme protects red blood cells and cell membranes against undesirable reactions with soluble peroxides.The dependence of glutathione peroxidase on nutritional seleniums clarifies the antioxidant role of this essential micronutrient. Good seleniums nutrition is of key importance for antioxidant defense as well as efficient energy
metabolism.
