Is NutriCare | INFINITY DNA-Test useful for Blutzucker?

The NutriCare | INFINITY DNA-Test analyzes genetic variants linked to blood sugar metabolism (e.g., TCF7L2, GCK). However, individual SNP effects are small and heavily outweighed by diet, exercise, and lifestyle. Evidence is mostly from GWAS and mechanistic studies, not from randomized controlled trials proving clinical utility. The test may indicate a genetic tendency toward slightly higher fasting glucose, but it cannot diagnose or guide personalized treatment. For individuals with prediabetes or diabetes, established blood glucose monitoring and medical advice remain essential. Marketing claims often overstate predictive power. Overall: limited usefulness as part of a broader health assessment, but not a substitute for medical diagnostics.
