How are NutriCare | INFINITY DNA-Test and Sport related?

The NutriCare | INFINITY DNA-Test is marketed as a combined nutrition and sports genetic test. It claims to analyze SNPs (e.g., in ACTN3, PPARA, FTO) to provide personalized advice on sport type, recovery, or nutrient needs. However, the scientific evidence is weak: most variants have very small effects on athletic performance or metabolism. Studies consistently show that lifestyle factors (training, diet, sleep) dominate over the tested genes. Furthermore, no clinical trials demonstrate that following the test's recommendations leads to improved sports outcomes. The test may serve as a motivational tool for healthier habits, but it should not be used for medical or performance decisions. Be cautious of exaggerated claims: no DNA test can predict whether you will become an elite athlete or what training is optimal for you.
