Are you converting Folic Acid to L-Methylfolate?

Folic acid is allowed to be labeled folate or folicin. However, none of these are the active form of folate known as L-Methylfolate (or L-5-MTHF) which your body can put to work. It takes four separate biochemical reactions for your body to turn folic acid into active folate:

Absorption and Transformation Steps of Folic Acid vs Bioactiv Folate

The conversion of folic acid into L-Methylfolate is frequently disrupted by genetic factors, age-related problems, medications and metabolic obstacles.

  • Up to 40% of adults are affected by genetic flaws that limit the amount of folic acid converted to the active folate (L-Methylfolate) that neutralizes homocysteine.
  • Transformation of folic acid into active folate (L-Methylfolate) falls off after ingesting 200 mcg, and is saturated at doses in the region of 400 mcg. Higher doses result in unabsorbed folic acid circulating in the blood, and the long term biological effects of a lifetime of exposure to unmodified synthetic folate are not clearly known.


Unlike most B vitamin formulas, HS Fighters™ with Bioactiv Folate™ provides the active forms of folate (as L-Methylfolate) and B12 (as Methylcobalamin) to bypass obstacles that may limit your body's ability to absorb and transform these vitamins into active nutrients.
