L- and 6(S)- forms are biologically active, while D- and 6(R)- are not.HOW DOES L-5-METHYLTETRAHYDROFOLATE CALCIUM WORK?The forms of vitamin B9 include folic acid and folate. Folic acid is the supplemental or "synthetic" form of vitamin B9 and is typically the first line of treatment for folate deficiency and related health conditions. While folate is the natural form of vitamin B9, which occurs naturally in some vegetables.However, no matter folic acid or folate we ingest, both of them must be metabolized into Dihydrofolate (DHF), Tetrahydrofolate (THF), and then finally into L-5-Methyltetrahydrofolate (5-MTHF) to be used in the body. This fact means L-5-Methyltetrahydrofolate (5-MTHF) is useful for human only , but the whole convert process requires the MTHFR enzyme , if our body can't do this conversion effectively (lack of MTHFR enzyme) , folic acid and folate somewhat useless to us .L-5-Methyltetrahydrofolate (5-MTHF)is the only one form of folic acid and folate able to cross the blood-brain barrier, it plays a role in DNA synthesis and repair , promotes body's ability to produce healthy DNA, have healthy neurotransmitter production, and optimal cardiovascular, hormonal, cellular, liver and reproductive functions.Specification:ItemInspection StandardAppearanceWhite to light yellow crystalline powderCalcium content:(on anhydrous substance)7.0%-8.5%Related substancesSingle impurity≤0.1%Total Impurites≤2.5%Residual solventEthanol≤5000ppmWater content(KF)≤16.0%Chloride(CI)≤0.50%Arsenic(AS)≤1ppmHeavy metals≤20ppmBoron≤20ppmTotal Plate Count≤100cfu/gYeast and Mold≤≤100cfu/gSalmonellaNegativeE.ColiNegativeHPLC>97.0%
