A stable composition of S-adenosyl-L-methionine is disclosed which includes a salt of S-adenosyl-L-methionine and a pharmaceutically acceptable, water-soluble salt of a bivalent or trivalent metal. The salt of S-adenosyl-L-methionine is, for example, a salt of S-adenosyl-L-methionine with hydrochloric acid, sulfuric acid, p-toluenesulfonic acid, phosphoric acid, formic acid, acetic acid, citric acid, tartaric acid, or maleic acid; or a double salt of S-adenosyl-L-methionine with the foregoing acids. The salt of a bivalent or trivalent metal is, for example, calcium chloride, ferric chloride, magnesium chloride, or magnesium sulfate. A process for preparing the composition is also disclosed. The composition is suitable for preparing pharmaceutical preparations of S-adenosyl-L-methionine.
