Biomarkers play a crucial role in assessing longevity, as they provide valuable insights into the aging process and overall health. Common biomarkers used for longevity purposes include telomere length, which is an indicator of cellular aging, and levels of inflammation markers such as C-reactive protein and interleukin-6. Other important biomarkers include insulin sensitivity, oxidative stress markers, and lipid profiles. By measuring these biomarkers, researchers and healthcare professionals can gain a better understanding of an individual’s biological age and identify potential risk factors for age-related diseases. This information can then be used to develop personalized interventions aimed at promoting healthy aging and extending lifespan.
