L-Selenomethionine

Synonyme: (S)-2-Amino-4-(methylseleno)butyric acid; L-Selenomethionine; Se-Methyl-L-selenocysteine; L-Selenomethionine.

L-Selenomethionine has become a preferred selenium source in premium dietary supplements and clinical nutrition, driven by its superior bioavailability and ability to support a wide range of physiological functions. As an essential trace element, selenium plays a critical role in antioxidant defense, thyroid hormone metabolism, and immune function. The L-isomer is the natural form found in food and is more efficiently utilized by the body compared to inorganic selenium salts.

L-Selenomethionine is a selenoamino acid where selenium replaces the sulfur atom in methionine. It is naturally present in Brazil nuts, grains, and certain vegetables, but for commercial use, it is produced through chemical synthesis or fermentation. The compound is highly stable and water-soluble, making it ideal for various formulations.

Our L-Selenomethionine is standardized to ≥98.0% purity (HPLC), ensuring consistent potency and reliability. It is widely used in nutraceuticals, functional foods, and pharmaceutical applications targeting selenium supplementation, antioxidant support, and thyroid health.

Produktübersicht und Zusammensetzung

L-Selenomethionine is a white to off-white crystalline powder with a molecular formula of C5H11NO2Se and a molecular weight of 196.11 g/mol. It is the organic form of selenium, where selenium is covalently bound to methionine, enhancing its absorption and retention in the body. This form is readily incorporated into proteins, serving as a selenium reservoir.

The product is manufactured under strict quality control to meet USP/EP standards. It is available in various particle sizes to suit different formulation needs, ensuring optimal flow and blendability.
