What is the RDA for calcium in children and adolescents aged 9-18 years?

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

Answer: (C)

During adolescence, the body prioritizes rapid bone growth and mineralization, so calcium needs are higher to support this surge in skeletal development. The recommended daily allowance for calcium for children and teens aged 9 to 18 is 1300 mg per day. This higher target reflects the demand to build peak bone mass during puberty and is greater than the adult recommendation of about 1000 mg daily. Aiming for this intake supports proper bone health later in life, and is best achieved through calcium-rich foods or fortified products, with adequate vitamin D to aid absorption. If intake is insufficient, consider discussing supplementation with a healthcare provider.
