Vitamin D is a hormone now widely recognized to be important to many body systems and a large number of physiological processes, and it may also be one of the most common nutrient deficiencies in the world. Vitamin D is needed for intestinal calcium absorption, skeletal bone integrity as well as skeletal muscle strength and function, and has been associated with overall physical fitness. Vitamin D is critical for healthy immune function, and may reduce the risk of infection, especially respiratory tract infections. Given that essentially every tissue in the body has a receptor for vitamin D, it is hard to overestimate its importance. Many practitioners recommend supplementation to achieve blood levels of 25-OH-vitamin D between 50-80 nmol/L, which often requires doses of 1000-2000 IU per day, and more for those with common genetic variants affecting vitamin D metabolism.
