Which nutrient is essential for maintaining healthy bones?

Calcium is a crucial nutrient for maintaining healthy bones due to its role as the primary mineral found in bone tissue. It provides strength and structure to bones, which makes it essential for their development and maintenance throughout life. The body relies on a sufficient intake of calcium to form new bone and to keep bones dense and strong, reducing the risk of fractures and conditions such as osteoporosis.

While vitamin D is important for calcium absorption in the body, and magnesium also plays a role in bone health, calcium directly contributes to the physical structure of bones. Iron, although essential for blood health and oxygen transport, does not have a direct role in bone health. Thus, calcium is recognized as the key nutrient for bone integrity.
