PGA is reported to increase bioavailability of calcium by
increasing its solubility and intestinal absorption. Tanimoto et al.
(2007) demonstrated an increased intestinal absorption of calcium
even in post-menopausal women after a single dose of PGA. The increase
in solubility is attributed to the inhibition of the formation
of an insoluble calcium phosphate. Addition of PGA in the high
mineral food preparations accelerated the absorption of minerals
in the small intestine and also masked the extraneous taste of enriched
minerals. This effect has also been seen in animal feeds
where addition of PGA promoted the absorption of minerals such
as phosphorus, increases the strength of egg shells, or retains the
effect of decreasing the accumulation of body fat
