Jarrow Formulas® SAMe 400 provides a full 400 mg SAMe (net yield) from 800 mg of SAMe tosylate disulfate. SAMe 400 is manufactured under low temperature and low humidity and is enteric-coated to ensure a biologically active product.

With More of the Biologically Active S,S than R,S Form
Found in all living cells, SAMe is a metabolite of methionine (an essential amino acid). SAMeis a chiral molecule consisting of two forms: (S,S) SAMe and (R,S) SAMe. The biologically active form is the (S,S) structure, while the (R,S) structure is biologically inactive. Jarrow Formulas® SAMe is made naturally by microbiological fermentation and processed without chemical solvents to preserve 68-80% (S,S) SAMe.

SAMe supports:

Brain Metabolism and Mood*
SAMe methylation reactions are involved in the synthesis of
phosphatidylcholine, a substantial constituent of grey matter within the
brain and cellular membranes.* It has also been proposed to be involved
in the formation or metabolism of neurotransmitters, which helps to
support a balanced mood.*

Joint Health*
SAMe supports the production of healthy connective tissue through
transsulfuration.* In this transsulfuration process, critical components
of connective tissue known as glycosaminoglycans (GAGs), including
glucosamine and chondroitin, are sulfated by SAMe metabolites to
yield sulfated GAGs, such as glucosamine sulfate and chondroitin
sulfate, the building blocks of cartilage.*

Liver Function*
SAMe supports the synthesis of glutathione (GSH), which is
critical for antioxidant defenses and liver functions including phase

II detoxification.*
