Can INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch help with Sport?

The INFINITY DNA-Test with a 28-day plan and recipe book is marketed to support sports and fitness. However, the scientific evidence is weak: DNA tests can identify certain genetic variants related to muscle building, endurance, or recovery, but effect sizes are small and largely overshadowed by lifestyle, training, and nutrition. The included 28-day plan and recipe book are likely generic recommendations, not personalized based on your DNA results. No robust clinical studies show that such a test significantly improves athletic performance. Evidence is therefore marketing. For serious sports optimization, blood biomarkers (e.g., ferritin, vitamin D) and professional coaching are far more relevant. Caveat: No DNA test replaces medical or sports medicine advice.
