Ceruloplasmin is a biomarker that has shown potential for longevity purposes. As a copper-carrying protein, ceruloplasmin plays a crucial role in maintaining copper homeostasis and regulating oxidative stress in the body. Studies have linked higher levels of ceruloplasmin with lower rates of age-related diseases and increased lifespan. Monitoring ceruloplasmin levels could provide valuable insights into an individual’s overall health and potential longevity. While more research is needed to fully understand the relationship between ceruloplasmin and longevity, it remains a promising biomarker for assessing aging and age-related health outcomes.
