QTY - 60 Capsules

5 MTHF ES provides 10,000 mcg of 5-MTHF (5-methyltetrahydrofolate) per serving. 5-MTHF ES 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 ES is provided as Quatrefolic®the glucosamine salt of 5-MTHF ES. Quatrefolic has demonstrated greater stability, solubility, and bioavailability when compared to calcium salt forms of 5-MTHF ES.*

The Science: 

Good folate status is associated with a healthy mood.[5] 5-MTHF might improve trimonoamine neurotransmitter synthesis and help maintain a sense of calmness and a healthy outlook.4[6] In non-smoking adults, higher folate levels are indicative of gum tissue strength, and a range of vitamins including folate appear to act in support of oral health mechanisms.*[7,8] Folate intake is especially important for women of child-bearing age. Studies indicate that supplementing during pregnancy supports a healthy outcome.[9] In a 2010 study, researchers concluded that if a woman exhibits certain genetic variations during pregnancy, it will lead to reduced methylation capacity and subsequent DNA hypomethylation.*[10]
