The recommended daily calcium intake for children aged 9 to 18 years is 1300 mg. This recommendation is based on the critical role that calcium plays during these developmental years, particularly for supporting bone growth and density. During adolescence, significant skeletal development occurs, making adequate calcium intake essential to ensure that bones become strong and healthy.

Children in this age group experience rapid growth spurts, and their bodies have increased calcium needs to support the development of their bones and teeth effectively. Meeting the 1300 mg daily requirement helps reduce the risk of osteoporosis and fractures later in life, while also playing a vital role in overall health.

Other options listed, such as 800 mg, 1000 mg, and 1500 mg, do not align with the established guidelines by health organizations. The recommended levels are specifically set to optimize skeletal health during this crucial developmental period, directly contributing to long-term health outcomes. Thus, 1300 mg is the most appropriate target for calcium intake in this age group.
