Calcium plays a vital role in maintaining bone health by contributing to the density and strength of bones. Adequate calcium intake is essential to prevent conditions such as osteoporosis, a disease characterized by weak and brittle bones. Calcium works in tandem with other nutrients, like vitamin D and magnesium, for optimal absorption and utilization in the body. Regular weight-bearing exercise also supplements bone health. Consuming calcium-rich foods, such as dairy products, leafy greens, and fortified foods, can help ensure sufficient calcium levels and promote overall skeletal health throughout life.
