Biomarkers are crucial tools in determining biological age and predicting longevity. One particularly promising biomarker is Copper Serum, which has shown potential in assessing overall health and aging. Research has indicated that higher levels of Copper Serum are associated with improved cognitive function, cardiovascular health, and immune system function. Additionally, lower levels of Copper Serum have been linked to oxidative stress and inflammation, both of which are key factors in aging and age-related diseases. Thus, monitoring Copper Serum levels may provide valuable insights into an individual’s long-term health and potential longevity. Further research and clinical studies are needed to fully understand the role of Copper Serum as a biomarker for longevity.
