Myths vs facts: NutriCare | INFINITY DNA-Test and Sport

Claims from tests like NutriCare or INFINITY DNA-Test for sport are often exaggerated. Most analyze single SNPs (e.g., ACTN3, ACE, PPARGC1A) and derive recommendations for training type, recovery, or nutrition. However, the scientific evidence is weak: individual SNP effects on athletic performance are typically very small, ancestry-dependent, and not clinically meaningful. Moreover, multiple variants are combined without validated interactions. A DNA test cannot replace individualized coaching – factors like training status, diet, sleep, and motivation are far more important. Most claims are based on mechanistic or associative studies, not randomized controlled trials. Consumers should be skeptical of promises like 'optimized training' or 'genetically perfect diet'. Such tests may serve as inspiration but not as a basis for medical or sports science decisions. Safety note: Do not change supplements or training without consulting a doctor or sports scientist.
