TL;DR
The parameters of the best‐fit relationship permit reasonably precise calculation of the impact of various calcium dosing and dietary strategies.
Abstract
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.

The preliminary data suggest that calcium supplementation in the dosage used is not as effective as estrogen therapy for the prevention of early postmenopausal bone loss.

Indirect estimates suggest that adaptation to a low calcium diet and the higher absorption in young than old normal subjects are mediated by an increased V(max) rather than a decreased K(m).

The effect of coingestion of a meal on calcium absorption efficiency was investigated using Ca carbonate, milk, and a new Ca delivery system, CCM, and differences taken as a whole were highly statistically significant.

Measurements of true calcium absorption fraction in women were evaluated to see how closely calculations based on a single measurement of serum specific activity after administration of an oral calcium tracer might approximate the absorption value derived from the full, double-isotope absorption procedure.

Using the new method, TFCA was inversely related to dietary calcium (r = −0.45, P < 0.05), demonstrating that it could detect physiological changes in calcium absorption, and provides a simple way to measure T FCA and true fractional calcium absorption.

A method for estimating true fractional calcium absorption, which required only a single blood sample taken 5 hours after ingestion of an iso-acid, was described in October 1985.

Although between-individual differences at a given load were considerable, given a single-test result with a known carrier load, it is possible to predict quite accurately the results which would be obtained if a different carrier load were to be given.
