Is Longevity DNA Test useful for Blutzucker?

Whether a Longevity DNA Test is useful for blood sugar (Blutzucker) depends on expectations. The INFINITY DNA Test (metabolism analysis) examines genetic variants related to metabolism, which may include SNPs affecting glucose regulation (e.g., TCF7L2). However, effect sizes are typically small (GWAS-level). The test offers hypotheses, not prescriptions. Lifestyle factors like diet, exercise, and sleep have a much larger impact on blood sugar than any single gene variant. Longevity tests often bundle many markers with mixed evidence – some are mechanistic or even marketing-driven. For managing blood sugar, established clinical measures (fasting glucose, HbA1c, oral glucose tolerance) and professional guidance are far more reliable. The test can provide interesting insights but should not be used for medical decisions. Caveat: Not diagnostic; does not predict disease.
