  • Patent number: 6649753
    Abstract: This invention relates to the production of new & stable salts of S-adenosyl-L-methionine SAMe). The source of SAMe used in the salt formation is from chemical process wherein stereoselective methylation of S-adenosyl-L-homocysteine is achieved. The process for the salt preparation is simple, efficient & reproducible on large scale. The new salts were found to be stable at accelerated temperature for minimum 3 months.
