L-Methyl Folateis a biologically active form of folic acid that functions, in conjunction with vitamin B12, as a methyl-group donor involved in the conversion of homocysteine to methionine. The availability of methyl groups is essential for a variety of methylation reactions including the synthesis of DNA and proper neural tube closure and it is needed to form healthy cells, especially red blood cells. WHY L-5- METHYLTETRAHYDROFOLATE CALCIUM? It is the only form of folate that appears normally in the plasma and is internalized by cells for use. 7 times more bio available than folic acid. As because of higher bioavailability, it is more economical and highly efficient. Able to cross the “blood-brain” barrier to aid in the synthesis of neurotransmitters and other neurological benefits, unlike folic acid. Reduces toxic levels of homocysteine significantly greater than folic acid. Increases RBC folate better than folic acid.
