Vitamin D is crucial for musculoskeletal health as it facilitates the absorption of calcium and phosphorus, essential minerals for bone formation and maintenance. Adequate vitamin D levels help prevent osteoporosis and reduce the risk of fractures. It also plays a role in muscle function, supporting muscle strength and coordination. Furthermore, emerging research indicates that vitamin D may influence immune function and overall well-being. Ensuring sufficient vitamin D intake, through sunlight exposure, diet, or supplements, is vital for maintaining optimal muscle and bone health.
