Men’s Wellness Check | Männer-Gesundheits-Test: which supplements make sense?

A men's wellness test (e.g., from MyBody-X) analyzes DNA, blood markers, or microbiome and often suggests supplements. However, the scientific basis is generally weak. Only a few gene variants (e.g., VDR for vitamin D) have moderate evidence from human studies – but even then the effect is small, and supplementation should be based on measured deficiency, not genetics alone. For most men, vitamin D, omega‑3 fatty acids, magnesium, and zinc are reasonable if a deficit is confirmed. The tests typically provide 'inspiration,' not medical advice. Critically, many supplement recommendations rely on GWAS with tiny effect sizes or purely mechanistic hypotheses. Without a blood panel and medical guidance, one risks overdosing or wasting money. A sound approach: first test blood levels (vitamin D, ferritin, B12, omega‑3 index), then supplement targeted. DNA alone is insufficient. Evidence: marketing/unclear. Safety note: supplements are not drugs; consult a doctor for symptoms.
