Studies have shown that getting enough calcium throughout life can play a major role in preventing osteoporosis. The Citracal Osteoporosis Prevention Survey, commissioned by Mission Pharmacal, was initiated to provide insight into and create awareness about the need for osteoporosis and calcium education. Even those who correctly answered four servings a day may not be aware of what constitutes a serving. An overwhelming 79 percent of women surveyed mentioned the media as their main source for nutrition information, with medical doctor lagging behind at 58 percent. Only 30 percent incorporate a regular weight training or exercise program into their life, while 54 percent take a calcium supplement.
Calcium is important for more than just bones.
It is essential for muscle contraction, hormone secretion and blood clotting, and recently has been shown to have a positive role in maintaining blood pressure. In some studies, colon cancer has been linked to calcium-deficient diets. If a patient's diet lacks sufficient calcium, a doctor may suggest a calcium supplement. However, not all supplements are alike. Calcium carbonate has the highest concentration of calcium by weight but is relatively insoluble and is poorly absorbed when taken on an empty stomach.
