Vitamin D and Calcium Linked to Brain Lesions

High amounts of vitamin D and calcium may have a downside – they are being linked to an increased risk for brain lesions. At one time the thinking was that we couldn’t get enough calcium or vitamin D to help prevent osteoporosis and build strong bones, but this study reports that extra calcium may end up in the blood vessel walls. This can have an extremely undesirable effect for somebody with renal disease, impairing the body’s ability to excrete calcium regularly. The researchers have not found extensive results that conclude calcium as being the direct cause, but hypothesize that the calcification of the blood vessels is directly linked to a higher number of brain lesions and cognitive decline.
