5-methyltetrahydrofolate

/5-meth·yl·tet·ra·hy·dro·fo·late/ (-tet″rah-hi″dro-fo´lāt) a derivative of folic acid that is the principal form of folic acid during transport and storage in the body and that also acts as a source of methyl groups for the regeneration of methionine.

Data from the literature suggest that NO may modulate Hcy concentrations directly by inhibiting methionine synthase, which synthesizes methionine from homocysteine and 5-methyltetrahydrofolate (8), and indirectly via folate catabolism by inhibiting the synthesis of ferritin (9), which promotes the oxidative cleavage of folate.

These lactoglobulins will bind 5-methyltetrahydrofolate (5-methylTHF) and many other forms of folate depending on pH (8).
There are also a few supplements that supply methyl groups, including particularly S-adenosylmethionine (SAMe), followed by methylsulfonylmethane (MSM), betaine (including the betaine from betaine hydrochloride), 5-methyltetrahydrofolate (a "new-in-the-stores" and more natural form of folic acid), and methylcobalamin (a form of vitamin B12).
1991), which interferes with the uptake of 5-methyltetrahydrofolate and decreases total folate binding (Stevens and Tang 1997).
It's important to consume the 5-methyltetrahydrofolate (5-MTHF) form of folate, since many people genetically are unable to metabolize the synthetic form of folic acid found in many supplements.

To prevent the build-up of potentially toxic levels of homocysteine, the cells use active folate, known as 5-MTHF or 5-methyltetrahydrofolate, in concert with vitamins B6 and B12, to convert homocysteine to other biologically useful compounds (see Figure 1 below).
