SAM-e 200 is manufactured under low temperature and low humidity and is enteric-coated to ensure a biologically active product. Contains More of the Active S,S Form Found in all living cells, SAM-e is a metabolite of methionine (an essential amino acid). SAM-e is a chiral molecule and consists of two forms: (S,S) SAM-e and (R,S) SAM-e. The biologically active form is the (S,S) structure, while the (R,S) structure is biologically inactive. Jarrow Formulas SAM-e is made naturally by microbiological fermentation and then specially processed without solvents to preserve 68-80% (S,S) SAM-e, the highest active level available. SAM-e has been clinically shown to have the following benefits: Joint Strength SAM-e supports the production of healthy connective tissue through transulfuration. In this process, critical components of connective tissue, including glucosamine and the chondroitin sulfates, are sulfated by SAM-e metabolites. Brain Metabolism SAM-e methylation reactions are involved in the synthesis of neurotransmitters such as L-DOPA, dopamine and related hormones, epinephrine and phosphatidylcholine (a component of lecithin). Longevity Methylation of DNA appears to be important in the suppression of errors in DNA replication. Demethylation of DNA is considered a contributor to the aging process. Proper methylation through substances such as SAM-e positively influences longevity. Liver SAM-e metabolism supports the synthesis of glutathione (GSH) and glutathione-dependent enzymes (glutathione peroxidase and glutathione-S-transferase), which are substances important for liver function.
