Vitamin D and health issues--questioned benefits

The easy access to measurement of serum 25-hydroxyvitamin D (vitD) levels created a surge in interest to learn more of its potential health benefits and its association with prevention of chronic diseases. VitD effects on bone and fracture risk were studied extensively, resulting in clinical guides that stress the need for adequate vitD supplementation. In addition, data are accumulating on its relevance to cardiovascular disease, cancer, cognition and other health domains.
