In order to be effectively used by the body folic acid must be converted to its active form. Up to one-third of the U.S. population may have a genetic enzyme defect that prevents them from converting folic acid (even folinic acid) into active 5-MTHF. 5-MTHF supplementation would be more effective for these individuals. It is also the only form that is capable of crossing the blood brain barrier.
Along with vitamin B12, 5-MTHF functions as a methyl-group donor necessary for 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 also essential for the conversion of homocysteine to Methionine. Methylcobalamin supports red blood cell formation, nervous system health, homocysteine and folate metabolism, melatonin synthesis. N-Acetyl-L-Cysteine (NAC) is a source of the conditionally essential amino acid L-cysteine and a precursor to glutathione.
