5-MTHF ES provides 17,000 mcg of 5-MTHF (5-methyltetrahydrofolate) per serving. 5-MTHF is the most biologically active form of the water-soluble B vitamin, folate; and it may be the preferred form for those with variations in digestion, absorption, or folate metabolism. Data suggest that in comparison to synthetic folic acid, 5-MTHF increases plasma folate more effectively. In this formula, 5-MTHF is provided as Quatrefolic®—the glucosamine salt of 5-MTHF. Quatrefolic has demonstrated greater stability, solubility, and bioavailability when compared to calcium salt forms of 5-MTHF.*
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
