Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The claim is specific, empirical, and contestable regarding whether nutrient requirements change by age. Multiple retrieved papers directly examine calcium and iron requirements across infancy, childhood, and adolescence, demonstrating that these needs vary by age group. Therefore, the claim is supported by the evidence.
