Why supplement?

✓

Already-reduced folate

Methylfolate (5-MTHF) can enter one-carbon metabolism without reduction by MTHFR. The uses are DNA synthesis and blood formation, and pre-pregnancy neural-tube nutrition.

DNA and blood formation

Methylfolate (5-MTHF) is a source of Vitamin B9 (Folate). Folate takes part in one-carbon metabolism and red-cell maturation. This form supplies folic acid or already-reduced folate; pre-pregnancy nutrition is a common setting.
