The invention provides a stable lyophilized composition of 5,10 methylenetetrahydrofolate suitable for use in the treatment of cancer and other therapies. The composition comprises 5,10-MTHF in combination with citric acid and ascorbic acid, with the ratio of citric acid to ascorbic acid from about 0.75:1 to about 2.25:1 by weight, and the ratio of total citric acid and ascorbic acid to 5,10-MTHF from about 1.4:1 to about 3.4:1 by weight. Prior to lyophilization, the solution is adjusted to an essentially neutral pH. |
