Many postmenopausal women have a calcium intake far below the recommended amount and, in addition to attempting to improve their diet, need a calcium supplement. The aim of the study was to assess the effects of the consumption of a high calcium mineral water on biochemical indices of bone remodeling in postmenopausal women with low calcium intake.
A 6-month randomized double-blind placebo-controlled trial was designed to assess the effects of a daily consumption of 1 liter of a high calcium mineral water on serum parathyroid hormone and biochemical markers of bone remodeling in postmenopausal women with a dietary calcium intake lower than 700 mg/day. The placebo group drank 1 liter of a mineral water with a low calcium content. 152 women completed the trial.
The high calcium mineral water was able to lower serum PTH and the indices of bone turnover in postmenopausal women significantly. While warranting further study, high calcium mineral water could contribute to the repair of calcium deficiency and to the reduction of age-related bone loss in this population.

Steve - I know it is a little late in discovering this study, but given our passion for suggesting daily consumption of naturally-occurring sparkling water, we felt the need to share this with you. It was also a small study, but statistically relevant nonetheless.
San Faustino and Gerolsteiner are the most commercially available naturally-occurring sparkling mineral waters with high mineral content. We stress naturally-occurring because many sparkling mineral waters on the market (San Pelligrino and Perrier, for example) are infused with carbon dioxide, giving them the bubbly taste, but making the positive effect on bones less.
