Vitamin D plays a crucial role in calcium absorption in the intestines, making it vital for maintaining healthy bones. When Vitamin D levels are adequate, the body can effectively absorb calcium and phosphorus from the diet, essential minerals for strong bones. Insufficient Vitamin D can lead to decreased absorption efficiency, which may contribute to bone disorders such as osteoporosis. Moreover, adequate Vitamin D levels support muscle function and immune health. Therefore, ensuring sufficient Vitamin D intake through sun exposure or dietary sources is essential for overall skeletal health and maintaining calcium balance in the body.
