What is the RDA for vitamin D for children 1-18 years of age?

• A. 400 IU/day
• B. 800 IU/day
• C. 600 IU/day
• D. 1000 IU/day

Answer: (C)

The amount you need daily to meet the needs of nearly all healthy individuals in this age group is the RDA, and for children 1–18 years, that value is 600 IU per day. This amount supports bone health and calcium metabolism, recognizing that vitamin D comes from both diet and some skin synthesis with sun exposure. The other numbers reflect different groups or situations, not this age range’s standard requirement. For infants up to 12 months, 400 IU/day is recommended. An intake of 800 IU/day is more common for other populations (like older adults or specific deficiency cases) and isn’t the general pediatric RDA. A plan of 1000 IU/day would exceed the recommended daily amount for typical healthy children and is not the standard RDA, though it might be used under medical supervision in certain circumstances.
