Why is vitamin D good for the body? Vitamin D helps maintain Calcium and Phosphorous in the bones for proper mineralization. Vitamin D is also good for bone health, growth and remodeling by osteoclasts and osteoblasts. Osteoclast is a bone cell that absorbs and breaks down bone tissue allowing for the development of new bone. Osteoblast is a large cell that is responsible for bone formation and reformation. Our bones are constantly being broken down and re-built, which is why it is important to consume the correct amount of calcium and vitamin D to maintain proper bone growth. Vitamin D has other roles in the body as well, such as influencing cell growth, immunity and inflammation.
