How are HbA1c and Langlebigkeit related?

HbA1c (glycated hemoglobin) is a long-term blood glucose marker reflecting average levels over 2–3 months. Elevated HbA1c is strongly linked to diabetes and cardiovascular disease, which can reduce lifespan. However, HbA1c is not a direct 'longevity marker' – there is no robust evidence that a low HbA1c in healthy non-diabetic individuals extends maximum lifespan. Evidence is strong for predicting diabetes complications, but weak for direct longevity claims. MyBody-X offers blood tests that measure HbA1c, but DNA tests like the Longevity test do not include HbA1c. Caveat: HbA1c can be skewed by anemia, hemoglobin variants, or kidney disease. For individual assessment, medical check-ups and a holistic view of lifestyle, nutrition, and biomarkers are essential.
