Eaux minérales naturelles et santé osseuse

Bone is constantly remodeled by two types of cells with opposite and complementary action, osteoblasts and osteoclasts. In older subjects this process is unbalanced and leads to bone loss and osteoporosis. Calcium intake around 1g/day is required for a balanced calcium metabolism. In case of insuffi cient calcium intake, parathyroid hormone level increases and triggers bone resorption in order to raise the serum calcium to a normal level. Calcium supplementation blunts bone loss and decreases parathyroid hormone level. Calcium-rich natural mineral water is a source of calcium that is bioavailable. Intake of such waters can decrease parathyroid level and bone loss in elderly. Therefore these mineral waters can contribute to maintain an adequate bone health.
