Potent product on acceptable price.
L-methylfolate - the active form of folate in the blood and the only type that can cross the blood-brain barrier. Unlike regular folic acid, Metafolin does not require enzymatic conversion to L-methylfolate in the body. By providing L-methylfolate directly, this patented form of folic acid may have benefits for those who do not produce enough L-methylfolate in response to folic acid supplementation. For those who take proper doses of vitamins B12 and B6, and TMG (trimethylglycine), but still suffer from higher-than-optimal homocysteine, Metafolin may be the solution. - - - - - - - - - - - - - - - - The only one problem with this item is that Solgar company uses so many ingredients(magnesium stearate, mannitol, stearic acid) which hinder the absorption of active ingredient.
