Chapter 11. Calcium - FAO

The relationship between urinary calcium excretion and calcium intake is given by the equation: Cau = 0.078 Cai + 137 ± 11.2 (SD) mg/day, where Cau is urinary calcium and Cai calcium intake. True absorption is an inverse function of calcium intake, falling from some 70 percent at very low intakes to about 35 percent at high intakes ( Figure 15 ).
