Low dietary levels of Calcium increase the risk of high blood pressure. Severe deficiency can lead to abnormal heartbeat, dementia and convulsions. As we age the risk of deficiency escalates because of decreased absorption due to lowered stomach acidity. A good accumulation of Calcium in the bones in the early stages of life is the best prevention of age-related bone loss and fractures. Studies show, however, that in post-menopausal women supplemental Calcium may slow bone loss, furthermore the rate of reduction can be sufficient to potentially reduce the risk of fracture over time.
