Known as the ‘Sunshine Vitamin’, Vitamin D is critical to our health. Humans once spent a lot of time outdoors, receiving the benefit of the sun’s interaction with cholesterol on the skin to produce the essential Vitamin D. Humans also once ate nutrient-rich foods high in Vitamin D – fatty fish, egg yolks, liver, etc.
In the modern world, many people are deficient in Vitamin D and it has serious health consequences. Vitamin D is more like a hormone than a ‘vitamin’ – many of the body’s functions, including the commonly known calcium and phosphorus absorption are the major roles it plays; however, Vitamin D plays a much deeper role than only calcium homeostasis.
This essential nutrient helps fight disease – from the flu to heart disease to multiple sclerosis. It also plays an important role is maintaining moods and keeping depression at bay.
