DL-Methionine methylsulfonium chloride, also named Vitamin U, is a powerful antioxidant. It is a sulfur derivative substance. Graviola leaves contain much vitamin U[1]. Vitamin U have unique antioxidant effect. It could prevents Galactosamine-induced gastric damage and protects pentylenetetrazole-induced brain damage in rats[2-3].
Vitamin U (DL-methionine methylsulfonium
chloride) is a natural methionine-derivative,
found as an active component in the
methionine cycle of plants where it serves as
a substrate for methyl transferases
(Augspurger et al., 2005). Historically this
compound has been utilized as either a cure or preventative against gastric and duodenal
ulcers (Nakamura et al., 1981).
DL-Methionine Methylsulfonium Chloride is a compound comprised of γ-glutamyl peptide and amino acid that have a sucrose-like taste.
S-Methionine methylsulfonium (SMMS) chloride is a derivative of methionine metabolism in some plants. SMMS has potent therapeutic effects on gastrointestinal ulceration potentially via its ability to promote dermal fibroblast migration and growth.
