Iron Saturation

Iron saturation is a critical biomarker used by longevity experts to evaluate overall health and potential longevity. It measures the amount of iron bound to transferrin in the blood, reflecting the body’s ability to transport and utilize iron effectively. An optimal iron saturation level is essential for promoting longevity, as both iron deficiency and excess can lead to various health issues and shorten lifespan. Interpreting iron saturation involves assessing whether the level falls within the optimal range, typically between 20-50%. A lower iron saturation may indicate iron deficiency, which can lead to fatigue, weakened immune function, and cognitive impairment. Conversely, high iron saturation levels can result in oxidative stress and tissue damage, increasing the risk of age-related diseases such as heart disease and cancer. By monitoring and managing iron saturation levels, individuals can support healthy aging and reduce the risk of age-related diseases. Longevity experts use this biomarker as part of a comprehensive approach to promoting longevity and vitality, emphasizing the importance of maintaining an optimal iron saturation level through balanced dietary intake and appropriate supplementation. Regular monitoring of iron saturation enables early intervention to prevent adverse health outcomes and optimize overall well-being.
