EPA (Eicosapentaenoic Acid) is a valuable biomarker used in assessing longevity. It is an omega-3 fatty acid found in fish oil and has been linked to numerous health benefits, including reducing inflammation, improving cardiovascular health, and supporting brain function. High levels of EPA in the body are associated with a lower risk of chronic diseases and age-related decline. Measuring EPA levels can provide valuable insights into an individual’s overall health and potential for longevity. Incorporating EPA-rich foods or supplements into one’s diet can help maintain optimum levels of this biomarker for promoting longevity and healthy aging.
