Abstract

Maximizing calcium retention during adolescence to optimize peak bone mass is a key to prevention of osteoporosis. It has been proposed that above calcium intake of approximately 1500 mg/day there is no further effect of dietary calcium on calcium retention (AJCN 55:992,1992). To determine the calcium intake resulting in maximal calcium retention in adolescent females, calcium balance was measured in 35 females aeed 12.0±1.3 years. Tanner Score 3.8±0.8 on nine dietary calcium levels ranging from 823±167 mg Ca/day to 2164±137 mg Ca/day. The study design was a crossover with each subject studied under two dietary calcium levels. Nonlinear regression analysis showed that the maximal accretion was 423 mg/day (Fig. 1). The current RDA of 1200 mg Ca/day allows 65% of that required to achieve optimal retention during adolescence.
