Research has recently found that vitamin D has a protective effect against arterial stiffness and impaired blood vessel relaxation.
Study participants with reduced levels of vitamin D had increased arterial stiffness and vascular function impairment. However, among those whose vitamin D levels were normalized over a six month period, vascular health improved and blood pressure measurements declined.
Science Newsline Reports:
"The results add to evidence that lack of vitamin D can lead to impaired vascular health, contributing to high blood pressure and the risk of cardiovascular disease."
In related news, researchers have also found that high level of vitamin D could be protective against the development of early age-related macular degeneration (AMD), a leading cause of vision loss in adults.
In women younger than 75, those who had 25-hydroxyvitamin D concentrations lower than 38 nanomoles per liter were more likely to have age-related macular degeneration than women with concentrations greater than 38 nanomoles per liter.
