Folic acid and also food folate are not biologically active and need to be converted to the metabolically active 5-methyltetrahydrofolate (5-MTHF) through a multi-steps process where the enzyme methylenetetrahydrofolate reductase (MTHFR) owns a key role. Quatrefolic bypasses the 5-MTHF conversion which leads to better absorption and utilization of folic acid. 
Folic acid is needed for the body to produce DNA and RNA, convert carbohydrates to energy, as well as create new red and white blood cells
