5-MTHF 1mg - 60 Capsules | Thorne

Active folate for mood, heart health, fetal development, and nerve support.

5-MTHF is an active, tissue-ready form of folate, an essential B vitamin that supports heart, brain, and blood health.

5-MTHF, also known as Methylfolate, is the preferred form of folate supplementation because it is the active form of folate used by the body’s tissues.

Many individuals don't get sufficient 5-MTHF (L-5-Methyltetrahydrofolate), the active form of folic acid, because they have intestinal or liver dysfunction, or because they are among the three out of five Americans whose genetic makeup makes it difficult to convert folic acid into active 5-MTHF.
