MyBody-X angle on Sportgene Ernährung

MyBody-X offers DNA tests that include sports-related genes such as PPARGC1A (rs8192678, Gly482Ser). This variant has been linked to endurance performance in meta-analyses, but the effect size is small. Translating this into a personalized supplement regimen (e.g., specific nutrients to boost mitochondrial function) is not supported by evidence. No randomized controlled trials show that gene-targeted supplementation improves performance. Training, overall diet, and recovery are far more influential. The test can serve as lifestyle inspiration, but should not be the sole basis for expensive supplement purchases or drastic dietary changes. Beware of marketing claims that overstate small genetic effects. Evidence: human-moderate for association, marketing for supplement claims.
