Question: 1 / 400

Which nutrient is most important for bone health?

Iron

Calcium

Calcium is the most important nutrient for bone health because it plays a crucial role in building and maintaining strong bones. Approximately 99% of the calcium in the human body is stored in bones and teeth, where it provides structure and strength. Adequate calcium intake throughout life, particularly during the formative years, helps achieve peak bone mass, which is essential for preventing osteoporosis and bone fractures later in life.

In addition to calcium, vitamin D also contributes to bone health by improving calcium absorption in the intestine. While it is essential, calcium is the primary component that directly strengthens the bone structure itself. Other nutrients like iron and folic acid serve critical roles in other bodily functions but do not have a direct impact on bone density and strength like calcium does. Therefore, when focusing on nutrients specifically tied to supporting and sustaining bone integrity, calcium stands out as the most vital nutrient.
