Vitamin D plays an important role in overall health and in maintaining strong bones. It helps the body absorb calcium and phosphorus. It helps to convey calcium to the bones and teeth and helps regulate the amount of calcium that remains in the blood. Vitamin D helps protect against bone loss and plays a role in nerve and muscle function, as well as the body’s immune system.

Our nerves need Vitamin D to be able to send messages from the brain to other parts of our bodies; our muscles need it to move; and our immune systems depend on it to be able to fight off bacteria and viruses.
