What are the best foods for healthy bones? Eat these to help fight osteoporosis. Build a strong structure. When it comes to building strong bones, there are two key nutrients: calcium and vitamin D. Calcium supports your bones and teeth structure, while vitamin D improves calcium absorption and bone growth. These nutrients are important early in life, but they may also help as you age.
Vitamin D is the name given to a group of fat-soluble prohormones (substances that usually have little hormonal activity by themselves but that the body can turn into hormones). Vitamin D helps the body use calcium and phosphorus to make strong bones and teeth. Skin exposed to sunshine can make vitamin D, and vitamin D can also be obtained from certain foods. Vitamin D deficiency can cause a weakening of the bones that is called rickets in children and osteomalacia in adults. Two major forms of vitamin D that are important to humans are vitamin D2, or ergocalciferol, and vitamin D3, or cholecalciferol.
