Based on bone health evidence, what is the RDA for calcium in children and adolescents 9-18 years of age?

• A. 1000 mg/day
• B. 1500 mg/day
• C. 1300 mg/day
• D. 1200 mg/day

Answer: (C)

Bone health during adolescence hinges on building peak bone mass, and calcium is the key mineral driving that mineralization. Because this is a period of rapid bone growth, the intake recommended to support bone development is higher than in adults. The daily amount advised for children and adolescents aged 9 to 18 is 1300 mg. This level helps ensure there’s enough calcium available for bone formation, assuming adequate vitamin D status to aid absorption and normal growth patterns. In practice, teens typically meet or approach this through dairy products and fortified foods; if intake falls short, dietary strategies or a supplement can help, while staying mindful not to exceed safe upper limits.
