Based on bone health evidence, what is the RDA for calcium in children 4-8 years of age?

• A. 900 mg/day
• B. 1200 mg/day
• C. 1000 mg/day
• D. 800 mg/day

Answer: (C)

Bone health during growth relies on having enough calcium to support bone mineralization as the skeleton expands. For children aged 4 to 8 years, the evidence-based daily intake that best supports this growth is 1000 mg of calcium.

This amount matches the standard recommendations derived from studies of bone accretion and peak bone mass development in early school years. It reflects what most healthy children need to maintain adequate calcium availability for bone formation, and it’s a level that is feasible to achieve through a typical diet (dairy products like milk, yogurt, and cheese, plus fortified foods and some leafy greens).

Going higher than this amount isn’t shown to provide additional bone benefits for this age group and could risk excess intake, which is unnecessary and may interfere with the absorption of other nutrients if consumed in very large amounts. The goal is to meet the 1000 mg/day target while staying within the overall safe intake range for this age.
