The Active Ingredient Is: 5-MTHF (L-5-Methyltetrahydrofolate)
5-MTHF is the biologically active form of folate, a water-soluble B vitamin crucial for cell growth, metabolism and methylation processes.
This form is provided as L-5-MTHF in a allergen-free vegetarian capsule, designed for users seeking folate support without common allergens.
What Does 5-MTHF Do?
5-MTHF takes part in methylation and red blood cell formation, helping folate levels in the body. Research suggests it may be more absorbable than folic acid in individuals with certain genetic variants, supporting normal metabolic function and vascular health aspects in keeping with EFSA guidance.
Dr. Greenberg of Johns Hopkins University found that 5-MTHF can circumvent metabolic blocks in folate metabolism, aiding folate status in relevant individuals.
