From the Manufacturer
L-Methylfolate 1mg, provided as Quatrefolic – the glucosamine salt of 5-MTHF, 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.
Quatrefolic has demonstrated greater stability, solubility, and bioavailability when compared to calcium salt forms of 5-MTHF.
Data indicate that supplementing with 5-MTHF increases plasma folate more effectively than folic acid.*
