Questions people ask about Sportgene Labor

As an endurance athlete, you're asking whether a gut microbiome test can tell you which bacteria to boost for better performance. The short answer: not yet. Observational studies show associations between certain bacteria and athletic performance, but causal evidence is lacking. GWAS (e.g., PMC12987725) reveal only tiny effect sizes, far from actionable. No commercial test is validated for sports optimization. The microbiome is highly individual and influenced by diet, training, and environment. While a test might indicate low diversity or specific taxa, it cannot prescribe targeted probiotics for performance. Current evidence supports general strategies: high-fiber diet, fermented foods, and adequate recovery. Beware of overclaiming – the evidence is weak, and focusing on single bacteria may distract from proven training and nutrition principles. Always consult a sports nutrition professional before making changes based on such tests.
