Most people are familiar with vitamin D’s role in helping the body absorb calcium from the diet. Vitamin D has many important roles in the body, including bone formation and maintenance and recently, research has shown that vitamin D is important in protecting the body from a wide range of diseases such as osteoporosis, cardiovascular disease and diabetes. It is widely thought that vitamin D also plays an important role in the modulation of the inflammation system by regulating the production of inflammatory proteins and immune cells, which are crucial for the development of many immune-related diseases. Recent evidence suggests that low vitamin D concentrations are associated with increased levels of inflammatory markers.
