L-5-Methyltetrahydrofolate Calcium, Food Grade

 

Introduce:
L-5-Methyltetrahydrofolate Calcium (L-5-MTHF-Ca) is a synthetic derivative of folic acid, the predominant, naturally occurring form of folate. It is synthesized by reduction of folic acid to tetrahydrofolic acid followed by methylation and diastereoselective crystallization (in water) of L-5-MTHF as its calcium salt. The product contains variable amounts of water of crystallization.
