The provided context does not contain specific studies on CRP in men. Generally, C-reactive protein (CRP) is a well-established but non-specific inflammatory marker. In men, baseline CRP levels tend to be slightly lower than in women, yet elevated CRP (>2–3 mg/L) is an independent risk factor for cardiovascular events (meta-analyses, e.g., Emerging Risk Factors Collaboration). The evidence is robust (human-strong), but CRP is not a standalone diagnostic tool; it is used in risk stratification (e.g., SCORE2, Reynolds Risk Score). Importantly, CRP is influenced by acute infections, injuries, smoking, obesity, and metabolic syndrome. A single elevated value should not be overinterpreted. Consumer DNA tests often measure only genetic predispositions (e.g., CRP gene polymorphisms), which explain only a small fraction of variance; clinical relevance is limited. For men with cardiovascular risk profile, CRP measurement can be useful, but always in combination with other risk factors. Supplements or lifestyle changes (e.g., omega-3, exercise, weight loss) may lower CRP, but evidence for hard endpoints is mixed. Conclusion: CRP is a useful but context-dependent marker; the predictive power of genetic tests is low.
