The importance of vitamin D for a healthy body is well documented. Produced by the body in response to sunshine, vit D, often referred to as the sunlight vitamin, is vital for healthy bones, muscles and teeth.
Those at particular risk of a vitamin D deficiency include people with higher levels of melanin, those living in cities where sunlight may be obstructed by tall buildings, obese or overweight people, anyone who works indoors during daylight hours and those who eat a meat-free diet.
