MTHFR and Methylation: What the Gene Variant Means and How to Optimize Your Protocol
MTHFR variants affect 40-60% of people and reduce the conversion of folic acid to active methylfolate by 30-70%. Methylation powers DNA repair, neurotransmitter synthesis, and detoxification. Protocol: replace folic acid with methylfolate, add methylcobalamin B12, and test homocysteine — goal below 7 μmol/L.
