Calcium Bioavailability from Mineral Waters with Different Mineralization in Comparison to Milk and a Supplement

Abstract

Given an equivalent bioavailability of calcium in all test products, neither a high concentration of SO₄^2- or of HCO₃ influenced the bioavailability of calcium. Accordingly, the use of mineral water with high concentrations of calcium constitutes a calorie-free calcium source that can improve calcium supply.
