Essential nutrients for bone health include calcium, vitamin D, phosphorus, and magnesium. Calcium is the primary building block for bones, while vitamin D enhances calcium absorption and promotes bone growth. Phosphorus works in conjunction with calcium to form strong bone structure. Magnesium supports bone remodeling and plays a role in converting vitamin D into its active form. Additionally, regular weight-bearing exercise can strengthen bones. A well-rounded diet that includes these nutrients helps prevent osteoporosis and maintains overall skeletal health.
