More Vitamin D, Less Depression
Researchers in this study measured vitamin D levels and symptoms of depression in 7,970 U.S. men and women aged 18 to 39. Half of all participants had low levels of vitamin D, and 20 percent were deficient, with vitamin D levels of 50 nanomoles per liter of blood or less. Those with good levels of vitamin D, 75 nanomoles of vitamin D per liter or more, were 46 percent less likely to be depressed compared to those who were deficient. Doctors don’t know if depression causes or results from low vitamin D, and encourage early vitamin D testing and taking vitamin D supplements.
