Crucial micronutrients for bone health include calcium, vitamin D, and magnesium. Calcium is essential for bone development and maintenance, while vitamin D assists in calcium absorption. Magnesium plays a role in bone structure and converting vitamin D into its active form. Ensuring adequate intake of these micronutrients through a balanced diet is vital for reducing the risk of osteoporosis and maintaining strong bones as one ages. Regular physical activity also complements nutrient intake, promoting overall bone health.
