Role of Vitamin D in the Body
First, vitamin D performs an essential function for bone health: our body needs it to absorb calcium. Calcium is known to be one of the main minerals that make up bones, so it’s understandable that getting enough vitamin D helps maintain good bone mass. Indeed, a good intake of vitamin D could help prevent osteoporosis. In addition, vitamin D is associated with the maintenance of muscle function. This vitamin could therefore help improve balance and prevent falls and related fractures, especially in elderly people.
Scientific research also tends to show a link between vitamin D deficiency and a weakened immune response, particularly against certain infections.
