Dutch TNO study confirms high calcium bioavailability of PURACAL calcium sources

The efficacy of a calcium source depends on the availability of calcium for absorption from this source. In Current Topics in Nutraceutical Research 2003, 1 (2), pp.161-168, the TNO Nutrition and Food Research Institute (the Netherlands) recently published an in-vivo study into calcium absorption from calcium sources in postmenopausal women.

The TNO study showed that PURACAL calcium sources are highly bioavailable calcium sources, from which calcium is significantly better absorbed in comparison with calcium phosphate. No differences in calcium absorption were found between calcium L-lactate supplements taken with an Asian or a Western breakfast. Calcium from PURACAL calcium sources is as bioavailable as calcium from milk, and therefore PURACAL calcium lactate and PURACAL calcium lactate gluconate have been proven to be very good calcium sources for calcium fortification of food.
