What is the primary benefit of Vitamin D for bones?

Vitamin D plays a crucial role in maintaining bone health primarily because it aids in the absorption of calcium from the diet. Calcium is a vital mineral for bone formation and strength. Without sufficient vitamin D, the intestines cannot effectively absorb calcium, which can lead to weakened bones and conditions such as osteoporosis or rickets. By enhancing calcium absorption, vitamin D ensures that the bones receive the necessary nutrients they need to remain dense and strong, thus preventing fractures and other bone-related issues. This connection between vitamin D and calcium makes it essential for the proper development and maintenance of a healthy skeletal system.
