Serious Health Issues Arise When Vitamin D Is Too Low, Or Too High

A statistical study of the vitamin D levels and mortality rates of nearly 250,000 Danes confirms a correlation between earlier death and too low levels of vitamin D, but also finds a connection between too high levels and a greater risk of death by stroke or heart attack. The researchers found that a vitamin D level below 50 or over 100 nanomol per liter is associated with higher mortality rates. “We should use this information to ask ourselves whether or not we should continue to eat vitamins and nutritional supplements as if they were sweets,” the researchers said.
