S-Adenosylmethionine (SAM) is an organic compound synthesized from methionine and ATP under the catalysis of methionine adenosyltransferase. Its CAS number is 485-80-3 with a molecular weight of 399.445.
It adopts a high-activity stable salt form (SAMe 1,4-butanedisulfonate) with strictly controlled moisture levels to resist degradation and prevent oxidation.
Owing to its good water solubility and 80-mesh fine powder physical profile, it is well suited for tablets, capsules, dry powder blends, and functional animal feed additions.
Standard packaging includes 1kg per bag/box (double plastic bag with aluminum foil inner bag) and 10kg or 25kg+ packed in drums or cartons with double-layer internal plastic liners.
Express door-to-door courier (EMS, DHL, UPS, FedEx) takes 3-7 days for shipments under 25kg; air cargo takes 3-7 days; and sea freight takes 10-35 days for large volume orders over 100kg.
