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

The INFINITY DNA Test including a 28-day plan and recipe book is marketed as a comprehensive package for sports and nutrition. However, the provided context lacks specific scientific evidence for this test. In general, direct-to-consumer DNA tests can offer insights into genetic variants related to athletic performance, recovery, or nutrient metabolism (e.g., ACTN3, PPARGC1A). Yet effect sizes are typically small, and personalized recommendations are often based on simplified models. The included 28-day plan and recipe book are likely generic templates, not tailored to individual results. A critical concern is the blend of lifestyle product with health-related promises. Evidence for actual performance enhancement through such tests is weak to moderate. Without accompanying sports medicine supervision and objective performance diagnostics, the practical benefit remains questionable. Consumers should view the test as a motivational tool for a healthier lifestyle rather than a scientifically robust training guide.
