How to prepare for MTHFR Ernährung

Preparing for an 'MTHFR diet' should be evidence-based and not driven by marketing hype. MTHFR (methylenetetrahydrofolate reductase) is an enzyme that converts folic acid into its active form, 5-methyltetrahydrofolate (5-MTHF). Common polymorphisms like C677T or A1298C can reduce enzyme activity, but clinical relevance is often low—many people with these variants have normal homocysteine levels. A typical recommendation is to replace synthetic folic acid (found in many supplements) with methylfolate, since folic acid may not be efficiently converted when MTHFR activity is reduced. Additionally, ensure adequate intake of vitamin B12 (preferably as methylcobalamin), B6 (pyridoxal-5-phosphate), and riboflavin (B2), as these are cofactors in the methylation cycle. Important: A DNA test alone does not justify a radical dietary change. The evidence for personalized nutrition based on MTHFR is mostly mechanistic and not supported by large clinical trials. Blood homocysteine measurements are more informative. Consult a doctor before supplementing, as high doses of methylfolate can have side effects. MyBody-X tests provide clues, not diagnoses.
