Infant’s recommended dietary allowance for calcium:
Age 0-6 months are recommended to receive 200 mg of calcium and infants age 6-12 months are recommended to receive 260 mg of calcium per day.
Children’s recommended dietary allowance for calcium:
Ages 1-3 require 700 mg of calcium per day and ages 4-8 require 1000 mg of calcium per day.
Pregnant and nursing women recommended dietary allowance for calcium:
Pregnant and nursing women younger than 18 years are recommended to receive 1300 mg/day of calcium. Among pregnant and nursing women older than 18 years, 1000 mg/day of calcium is recommended.
Taking vitamin D with calcium:
Widespread evidence in various research reinforces the benefit of adequate vitamin D intake together with calcium to support absorption and assimilation of calcium in the body. For more detailed information on vitamin D, please see the section on vitamin D. According to the Food and Nutrition Board, Institute of Medicine vitamin D at a dose of 600 International Units (IUs) per day meets the needs of almost everyone in the United States and Canada. Infants need 400 IUs per day, and children need 600 IUs per day. People age 71 and older may need as much as 800 IUs per day because of potential changes in people’s bodies as they age. There is also evidence that higher intakes reduce mortality. The upper level intakes were set by the committee for both calcium and vitamin D. While these values vary somewhat by age, the committee concludes that once intakes of vitamin D surpass 4,000 IUs per day, the risk for harm begins to increase. Once intakes surpass 3,000 milligrams per day for calcium, the risk for harm also increases.
