Common mistakes around Sportgene Ernährung

Common mistakes around sports genetics and nutrition: Many believe a single gene (e.g., ACTN3, COMT) determines performance or nutrient needs. The reality is more complex: effects are small, ancestry-dependent, and overshadowed by training, diet, and lifestyle. Another mistake is assuming genetic tests can deliver a personalized nutrition strategy without biomarkers or clinical context. Most commercial offerings rely on weak or mechanistic evidence. Interpreting hormone values (e.g., testosterone) from home tests is also misleading, as they lack full axis assessment (LH, FSH, estradiol). Athletes should not rely on single SNPs but on proven training and nutrition principles. Genetics can offer hints, not guarantees. Caution is warranted when marketing claims derive strong recommendations from weak evidence.
