Vitamins
Methylfolate (L-5-MTHF, Active Vitamin B9)
Methylfolate (L-5-MTHF) is the biologically active form of folate (vitamin B9) that bypasses the need for genetic conversion, making it more readily available for cellular functions including DNA synthesis, neurotransmitter production, and homocysteine metabolism. Unlike synthetic folic acid, methylfolate can be utilized even by individuals with MTHFR genetic variants that impair folate metabolism. Dietary supplements are not FDA-approved to diagnose, treat, cure, or prevent any disease. Consult your doctor before starting any supplement.
