Is INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch useful for Sport?

The INFINITY DNA-Test including a 28-day plan and recipe book is marketed for sports optimization. However, the scientific evidence for such direct-to-consumer DNA tests in sports is weak. Most analyzed variants (e.g., ACTN3, ACE, FTO) have small effect sizes on performance or body composition. A 28-day plan based solely on DNA ignores critical factors like training status, individual tolerances, microbiome, and lifestyle. The recipe books are often generic rather than truly personalized. Independent clinical studies supporting the utility of these tests are lacking. For athletes, evidence-based guidance from a sports physician or registered dietitian is more reliable. The test may serve as a motivational tool, but results should not be treated as medical diagnoses or strict training prescriptions. Be cautious of exaggerated marketing claims.
