Folic acid from food or supplementation must be converted to its active forms to be used by the body.* This is a multi-step biochemical process that occurs in the intestines and liver. In the presence of intestinal or liver dysfunction this conversion may not occur sufficiently enough to meet the body's needs. Furthermore, up to 60 percent of the U.S. population may have a genetic enzyme defect that makes it difficult for them to convert folic acid into active 5-MTHF. For these individuals and many others, 5-MTHF supplementation may be a more effective method of folate repletion.*
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, coenzyme Q10, L-carnitine, and DNA.*
5-MTHF 15 mg is recommended for those who have been evaluated by a health-care practitioner as needing extra methylation support.
