Vitamin A (Retinol)

Vitamin A, also known as Retinol, is a crucial biomarker in assessing longevity. As a fat-soluble vitamin, it acts as a powerful antioxidant and immune system enhancer, combating oxidative stress and inflammation – both of which are significant contributors to aging and age-related diseases. Low levels of Vitamin A have been correlated with weakened immune function and an increased risk of mortality, 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. It is essential to interpret Vitamin A levels within the context of an individual’s overall health and lifestyle factors, and when combined with other biomarkers, it can offer a comprehensive understanding of an individual’s biological age and potential longevity.
