for infants are based on mean intake data from infants fed human milk as the principal fluid during the first year of life and on the studies that have determined the mean calcium content of breast milk. Additionally, information on calcium absorption and calcium accretion is taken into account.

With respect to estimating AIs for calcium for infants, studies reviewed previously in this report have provided the following information:

  • Based on infant weighing studies, a reasonable average amount of breast milk consumed is 780 mL/day. The average level of calcium within a liter of breast milk is 259 mg (± 59 mg). It is therefore estimated that the intake of calcium for infants fed exclusively human milk is 202 mg/day. This number is rounded to 200 mg/day.
