Overview

Thorne Methyl-Guard Plus provides the four B vitamins essential for methylation in their active, bioavailable forms: 5-MTHF (active folate, 1000mcg), methylcobalamin (active B12, 1000mcg), pyridoxal 5'-phosphate (active B6, 25mg), and riboflavin 5'-phosphate (active B2, 25mg). This formula is specifically designed for individuals with MTHFR gene variants who cannot efficiently convert folic acid to its active form. Proper methylation is essential for DNA repair, neurotransmitter synthesis, detoxification, and homocysteine metabolism.
