Crucial vitamins and minerals for maintaining bone health include calcium, vitamin D, magnesium, and phosphorus. Calcium is vital for bone density, while vitamin D enhances calcium absorption and supports bone growth. Magnesium plays a role in the structural development of bones, and phosphorus contributes to the formation of bone mineralization. Ensuring sufficient intake of these nutrients through dietary sources like dairy products, leafy greens, nuts, and fish is essential for preventing osteoporosis and maintaining strong bone structure throughout life.
