Alkaline Phosphatase (ALP) is a biomarker that is often used in longevity studies to assess overall health and potential lifespan. ALP levels in the blood can indicate liver or bone health, as well as other metabolic processes. High ALP levels may suggest underlying liver disease or bone disorders, while low levels can be associated with malnutrition or certain genetic conditions. Monitoring ALP as part of a comprehensive biomarker panel can provide valuable insights into an individual’s overall health and potential longevity, helping to identify areas for intervention and personalized health optimization strategies.
