Provided herein are methods for preparing stable solutions containing 5-methyltetrahydrofolate (MTHF). Also provided herein are stable compositions containing calcium 5-methyltetrahydrofolate (MTHF-Ca).

The invention relates to amorphous folate salt. The salt consists of a folate anion and an organic cation. The folate anion is selected from the group consisting of 5-formyl-(6S)-tetrahydrofolic acid, 10-formyl-(6R)-tetrahydrofolic acid, 5-methyl-(6S)-tetrahydrofolic acid, (6S)-tetrahydrofolic acid, 5,10-Methylene-(6R)-tetrahydrofolic acid, and its oxidized derivatives JK12A and Mefox, and the cation is an organic compound selected from the group arginine, choline, acetylcholine, 1,1-dimethyl-biguanidin and phenylethylbiguanidin. The cation is an organic compound with a complementary pharmacological activity.
