MyBody-X angle on MTHFR Genetik

The provided context does not contain specific information on MTHFR variants. In general, MTHFR (methylenetetrahydrofolate reductase) is a key enzyme in folate and homocysteine metabolism. Common variants (C677T, A1298C) are associated with elevated homocysteine levels, a risk factor for cardiovascular disease and neural tube defects. However, the evidence is mixed: mechanistic and GWAS studies show associations, but robust randomized trials proving benefit from supplementation (e.g., with active folate) are lacking. Many direct-to-consumer tests overstate clinical relevance. MyBody-X should clearly communicate that MTHFR genetics alone is not diagnostic and that lifestyle factors (diet, B-vitamins) are critical. Medical evaluation is recommended if homocysteine is elevated.
