Calcium supplements are generally needed after a fracture because during fracture healing, fibrous bone crust and bony bone scab will appear at the fractured end, which requires large amounts of calcium ions. It is recommended to eat more high-calcium foods, such as soy products, high-calcium milk, dairy products, shrimp meat, and deep-sea fish. At the same time, the sun can be properly exposed to the sun, which can promote the conversion of 7-dehydrocholesterol in the skin into active vitamin D3, which can promote the reabsorption of calcium ions from food in the small intestine, so that calcium can be actively supplemented, which can accelerate the deposition of calcium salts in the fracture site and thus promote fracture healing.
