Blood Vitamin D levels can predict future health risks and death

Free, circulating Vitamin D levels in the blood may be a better predictor of future health risks in aging men, according to a study being presented at e-ECE 2020. These data suggest the free, precursor form of vitamin D found circulating in the bloodstream is a more accurate predictor of future health and disease risk, than the often measured total Vitamin D. Since Vitamin D deficiency is associated with multiple serious health conditions as we get older, this study suggests that further investigation into Vitamin D levels and their link to poor health may be a promising area for further research.

Vitamin D deficiency is common in Europe, especially in elderly people. It has been associated with a higher risk for developing many aging-related diseases, such as cardiovascular disease, cancer and osteoporosis. However, there are several forms, or metabolites, of Vitamin D in the body but it is the total amount of these metabolites that is most often used to assess the Vitamin D status of people. The prohormone, 25-dihydroxyvitamin D is converted to 1,25-dihydroxyvitamin D, which is considered the active form of vitamin D in our body. More than 99% of all Vitamin D metabolites in our blood are bound to proteins, so only a very small fraction is free to be biologically active. Therefore the free, active forms may be a better predictor of current and future health.
