Mechanistically, MTHFR affects folate metabolism and homocysteine levels, which could theoretically influence recovery, inflammation, and cardiovascular endurance. However, robust human studies showing direct performance benefits from genotype-specific interventions are lacking. Many direct-to-consumer companies overstate clinical relevance. Most carriers are asymptomatic; elevated homocysteine can be normalized by adequate folate intake (e.g., leafy greens) without needing methylfolate supplements. For athletes with recurrent injuries or unexplained fatigue, a homocysteine test may be reasonable, but routine genetic screening is not supported. The German Society for Sports Medicine does not recommend genetic testing for performance assessment. Conclusion: MTHFR testing in sports is low-evidence unless there is medical suspicion of hyperhomocysteinemia. Consult a physician before supplementing.","area":"gesundheit","canonical_id":"gesundheit:canonical-64774790006ea6b2dc315107","id":"public-8bcc06edc27068cacefd816c","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: MTHFR in the context of Sport","score":21.62935924,"snippet":"Evidence for MTHFR variants (especially C677T) in sports is weak to moderate.

In sports, it is often linked to improved oxygen delivery and recovery. Evidence is moderate: some studies show benefits for endurance athletes with low baseline folate, but no consistent performance enhancement in well-nourished individuals. High doses can mask vitamin B12 deficiency, potentially leading to neurological issues. Therefore, testing folate status (e.g., serum folate, homocysteine) before supplementation is recommended. Most research focuses on endurance sports; data for strength or team sports are limited. Caveat: supplemental folic acid differs from natural food folate, and genetic variants (e.g., MTHFR) can affect conversion. Routine supplementation without confirmed deficiency is not evidence-based.","area":"gesundheit","canonical_id":"gesundheit:canonical-556d2e007aad6b9f15eda430","id":"public-e84ce9e9d2a0766dbc95f90f","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Folsäure in the context of Sport","score":21.33604231,"snippet":"Folic acid (vitamin B9) is crucial for DNA synthesis, red blood cell production, and homocysteine metabolism.
