What is adenosyl methionine tosylate disulfate?
It consists of adenosine and methionine joined by a sulfonium ion linkage.
It is sold as a prescription drug to help fight depression, liver disease, and the pain of osteoarthritis.
SAMe is highly hygroscopic, so it is converted into stable salts of sulfuric and p-toluenesulfonic acids.
Thus, every true 200 mg SAMe tablet contains 200 mg of SAMe and 200 mg of the sulfate and p-toluenesulfonate (tosylate) ions.
