Chemical Structure:

DL-METHIONINE METHYLSULFONIUM CHLORIDE Application:
DL-Methionine Methylsulfonium Chloride, also known as S-Methylmethionine Chloride or Vitamin U, is a quaternary ammonium salt structurally related to methionine. It is typically obtained from the methylation of DL-methionine and is valued for its stability and water solubility. As a biologically active amino acid derivative, this compound is used across nutraceutical, pharmaceutical, and cosmetic industries due to its metabolic compatibility and protective biochemical properties. It functions as a methyl donor and supports various synthetic and cellular protection pathways. In industrial applications, it is often provided as a white crystalline powder suitable for formulation and blending processes. Applications:
- Nutritional Supplementation and Feed Additives
DL-Methionine Methylsulfonium Chloride is incorporated into dietary and feed formulations to provide bioavailable sulfur and methyl groups. It supports amino acid balance, promotes growth in animal nutrition, and serves as a complementary source of methionine in compound feed production. - Pharmaceutical and Nutraceutical Formulations
Due to its biochemical role similar to methionine and its reputation as “Vitamin U,” this compound is used in health supplements aimed at maintaining cellular metabolism and gastrointestinal function. It may act as a functional ingredient in formulations designed to support overall metabolic balance and detoxification pathways. - Cosmetic and Personal Care Ingredient
In cosmetic science, DL-Methionine Methylsulfonium Chloride is valued for its potential to support skin barrier function and protect against environmental stress. Its amino acid structure aids in maintaining moisture and promoting a balanced skin appearance, making it suitable for use in creams, serums, and scalp-care formulations.
