Evidence check: INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch in the context of blood sugar

The INFINITY DNA Test with a 28-day plan and recipe book is marketed as a comprehensive metabolism analysis that may include blood-sugar-related variants (e.g., TCF7L2, GCKR, SLC2A2). However, the evidence is mixed: some variants are associated with fasting glucose or type 2 diabetes risk in GWAS, but effect sizes are small and easily overshadowed by lifestyle factors (diet, exercise, sleep). The 28-day plan and recipes are claimed to be DNA-based, but their added value over a general healthy eating plan is not scientifically proven. These tests are not clinically validated and cannot replace medical blood sugar diagnostics (e.g., HbA1c, fasting glucose, OGTT). Inflammation or medications can also affect interpretation. For evidence-based blood sugar management, continuous glucose monitoring (CGM) and personalized nutrition based on actual measurements currently have stronger support. Bottom line: the test may offer orientation, but not a basis for medical decisions.
