The biomarker Vitamin A (Retinol) plays a pivotal role in assessing longevity. As a fat-soluble vitamin, it serves as a potent antioxidant and immune system booster, combatting oxidative stress and inflammation, both of which are key factors in aging and age-related diseases. Low levels of Vitamin A have been linked to diminished immune function and increased mortality risk, while optimal levels are associated with improved overall health and longevity. Monitoring Vitamin A levels can provide valuable insights into an individual’s cellular health and resilience, offering a valuable tool for assessing and optimizing longevity.
