Folic Acid must first be converted to its active form by a series of biochemical steps before it is able to be used by the body. Metafolin® (L-methylfolate) requires no conversion because it is bioidentical to the bio-active form. In other words, it is ‘body-ready’. This can be useful for individuals whose bodies have difficulty converting folic acid to its active form. The active folate in this formulation promotes heart health. It also supports a healthy nervous system and the formation of healthy red blood cells.
