Myths vs facts: hsCRP and longevity

The role of hsCRP (high-sensitivity C-reactive protein) as a biomarker of inflammation is well-established, but its direct link to longevity is complex. Myth: A low hsCRP level guarantees a long life. Fact: Chronically elevated hsCRP is a risk factor for cardiovascular disease and may indicate inflammatory processes that accelerate aging. However, hsCRP is not a direct causal factor – many individuals with moderately elevated levels reach advanced age if other risk factors are controlled. Lifestyle interventions such as diet, exercise, and stress management have been shown to lower hsCRP, but whether this alone extends lifespan is not conclusively proven. Evidence comes mostly from observational studies; randomized controlled trials targeting hsCRP reduction with longevity as an endpoint are lacking. Thus, hsCRP is useful as a risk marker but not as a standalone predictor of longevity. Caveat: A normal hsCRP does not rule out other risks.
