“…The subject absorbed 95% of the calcium from a low-calcium feed and 85% from a normal-calcium feed [normal for age 45.6 Ϯ 2.5% (16)]. Calcium absorption from any intake is rarely greater than 80% in children, regardless of the type of feeding or calcium content (17).…”

“…Limited DXA data in this age group suggest that the accretion of calcium is similar to that in the first year of life, about 100-150 mg/day [1,12]. Recent stable isotope balance studies in this population demonstrated that intakes of 500-600 mg/day would be adequate to achieve this target, with the higher intake levels meeting the needs of nearly all individuals [13] (Figure 2). An interesting question is the ability of children this age to adapt to diets extremely low in calcium intake.…”

Determining calcium bioavailability is important in establishing dietary calcium requirements. In infants and small children, previously conducted mass balance studies have largely been replaced by stable isotope-based studies. The ability to assess calcium absorption using a relatively short 24-hour urine collection without the need for multiple blood samples or fecal collections is a major advantage to this technique. The results of these studies have demonstrated relatively small differences in calcium absorption efficiency between human milk and currently available cow milk-based infant formulas. In older children with a calcium intake typical of Western diets, calcium absorption is adequate to meet bone mineral accretion requirements.

“…In the age group of the 1-to <4-year-olds, according to Lynch et al [12] , 140 mg of calcium per day are retained for their growth needs. According to the calculation with the factorial method 1 and a calculated absorption rate of 45.6%, the average requirement for calcium is 474 mg/day ( table 2 ).…”

New Reference Values for Calcium

The nutrition societies of Germany, Austria and Switzerland are the joint editors of the ‘reference values for nutrient intake'. They have revised the reference values for the intake of calcium and published them in June 2013. The reference values for the calcium intake for infants are derived from the calcium content of breast milk. For infants from 4 to <12 months of age, the calcium intake from solid foods is included in addition to the calcium intake from breast milk. Thus, the reference values for infants are estimated values; they are 220 mg/day for infants to <4 months and 330 mg/day for infants from 4 to <12 months of age. As a parameter for determining the calcium requirement in children and adolescents, calcium retention is taken into account. The average requirement is calculated by the factorial method. A balanced calcium metabolism is calculated based upon calcium balance studies and used as a parameter for the determination of the calcium requirement in adults. On the basis of the average requirement, recommended calcium intake levels for children, adolescents and adults are derived. Depending on age, the recommended calcium intake ranges between 600 mg/day for children aged 1 to <4 years and 1,200 mg/day for adolescents aged 13 to <19 years; for adults, it is 1,000 mg/day.
