L-SelenoMethionine CAS: 3211-76-5

Selenomethionine or 2-Amino-4-(methylselanyl)butanoic acid is a naturally occurring amino acid. The L-selenomethionine enantiomer is the main form of selenium found in Brazil nuts, cereal grains, soybeans, and grassland legumes. Ideally, selenium should be supplemented in the form in which it occurs naturally in foods and this makes L-Selenomethionine a good addition in human supplements. L-selenomethionine as a source of selenium is added for nutritional purposes to food supplements. Selenomethionine’s antioxidant activity arises from its ability to deplete reactive oxygen species. It has been suggested by nutritionists that selenomethionine, which is an organic form of selenium, is easier for the human body to absorb than selenite.
