5-MTHF, provided as Quatrefolic, is the most biologically active form of the water-soluble B vitamin, folic acid. It is the preferred form of folate supplementation due to an array of conditions that can limit conversion or absorption of folic acid. Data indicate that supplementing with 5-MTHF increases plasma folate more effectively than folic acid.*
Really fast delivery. Very much appreciated. This product has helped me immensely. Thank you.
Great product and it worked!
This product is actually prescribed to my dog to maintain his liver health. He's been on it for a year with great results
