True calcium absorption was studied as a function of the size of the ingested load in healthy adult women, under meal conditions and at loads ranging from 15 to 500 mg calcium. Fractional absorption was highly inversely correlated with the logarithm of load (P less than 0.001). At the lowest loads, absorption averaged 64.0% and at the highest, 28.6%. The parameters of the best-fit relationship permit reasonably precise calculation of the impact of various calcium dosing and dietary strategies.
在进餐条件下，对健康成年女性摄入不同负荷（15至500毫克钙）的钙时的真实钙吸收情况进行了研究。钙的吸收分数与负荷的对数呈高度负相关（P小于0.001）。在最低负荷时，平均吸收率为64.0%，在最高负荷时为28.6%。最佳拟合关系的参数能够合理精确地计算出各种补钙剂量和饮食策略的影响。
