The in vitro methods proposed for estimating calcium bioavailability can be useful in studying the effect of dietetic factors. The aim of our work was to study the possible influence of different infant formula components – calcium, phosphorus, lactose, citric acid, ascorbic acid and proteins – on calcium bioavailability, considering dialysability to be an estimate of bioavailability. The 1981 method of Miller et al. with slight modifications (concerted action no 10 – FLAIR project) was applied to 18 commercial infant formulas of six different types: adapted, follow-up, preterm, hydrolysates, lactose-free and soy-based. Significant positive linear correlations between the amount of calcium dialysed and the calcium and phosphorus contents were found. However, there were no statistically significant correlations between the amount of calcium dialysed and the lactose, ascorbic acid or citric acid contents, In the case of proteins an exponential relationship was found between the amount of calcium dialysed and the protein content.
