Some observational studies suggest associations between low folate status and shorter telomeres or increased cardiovascular risk. However, randomized controlled trials on homocysteine-lowering with folic acid have not consistently shown extended lifespan or reduced all-cause mortality. Moreover, high intake of synthetic folic acid (≥1 mg/day) can mask vitamin B12 deficiency, which is particularly critical in older adults. The evidence for a direct longevity benefit is therefore moderate and largely based on association studies. Genetic variants in the MTHFR gene (e.g., rs1801133) affect the conversion of folic acid to active folate, making individual adjustment relevant. Consumer DNA tests can identify such variants but do not replace blood measurements. For evidence-based recommendations, folate intake should come from diet (leafy greens, legumes), with supplementation only for confirmed deficiency or specific risk groups (e.g., pregnancy).","area":"gesundheit","canonical_id":"gesundheit:canonical-c18a884e42cd00c1e34664b8","id":"public-33add72c8d8702fb088324ce","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Folsäure in the context of Langlebigkeit","score":20.89489361,"snippet":"Folic acid (vitamin B9) is essential for DNA synthesis, methylation, and homocysteine metabolism – processes linked to aging and longevity.
