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.1,2 .3,4,5,6 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.7,8,9 Vitamin D is critical for healthy immune function and may reduce the risk of infection, especially respiratory tract infections.10,11 Given that essentially every tissue in the body has a receptor for vitamin D, it is hard to overestimate its importance.12 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.13,14,15
