In concert with vitamin B12, 5-MTHF functions as a methyl-group donor involved in the conversion of the amino acid homocysteine to methionine. Methyl-group donation is vital to many biochemical conversion processes, including the synthesis of serotonin, melatonin, and DNA.
It is important for women of childbearing age to get enough folic acid - not just those who are planning to become pregnant. Only 50 percent of pregnancies are planned, so any woman who could become pregnant should get enough folic acid every day - especially before conception and during early pregnancy.
