Fitness | VITALITY DNA-Test: which supplements make sense?

The VITALITY DNA Test analyzes genetic variants related to energy metabolism, nutrient utilization, and fitness. Based on such tests, supplements like vitamin D, B vitamins, magnesium, omega-3 fatty acids, or antioxidants are often recommended. However, the scientific evidence for these recommendations is generally weak: many associations come from GWAS studies with small effect sizes, and individual impact is heavily influenced by lifestyle, diet, and blood levels. A vitamin D deficiency is more reliably detected by a blood test than by a VDR gene variant. Claims about determining 'detox capacity' from genes (e.g., GSTT2 pseudogene) are not scientifically supported. It is reasonable to use test results as a hint, but supplements should only be taken after consulting a doctor and, if needed, blood analysis. Marketing often overstates the predictive power. Bottom line: the test can offer suggestions but does not replace medical advice.
