Which statement correctly states the vitamin D RDA for children age 1–18 years?

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

Answer: (B)

Vitamin D supports calcium absorption and bone mineralization during growth. For children and adolescents aged 1 through 18, the recommended daily allowance is 600 IU per day, roughly 15 mcg. This amount is set to meet the needs of most healthy kids given typical sun exposure and dietary intake, helping support proper bone development. Infants up to 12 months have a lower target (about 400 IU daily), and higher amounts (like 800 IU daily) are more commonly discussed for older adults or specific circumstances, not for this age range. So 600 IU per day is the value that fits the 1–18 year age group.
