Calcium citrate, calcium carbonate and calcium with vitamin D are some of the more popular supplements used by seniors to stay healthy and strong. Hypercalcemia is when the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with how your heart and brain work. Hypercalcemia is usually a result of overactive parathyroid glands. In the case of men and women taking medication, such as Fosamax or Evenity, for osteoporosis, adequate calcium intake is recommended since the bone needs extra calcium to strengthen. All trials that showed the effectiveness of the medication were done, ensuring adequate intake of calcium and vitamin D. Bone Health Step 1: Calcium and Vitamin D. Calcium builds strong bones, but vitamin D helps the body absorb calcium. That's why postmenopausal women need 1,200 milligrams of calcium and at least 400 IU to 600 IU of vitamin D daily for better bone health. Many researchers and nutritionists now believe magnesium is more important than calcium in maintaining healthy bones. In addition, magnesium is responsible for more than 300 biochemical reactions, all necessary for optimum health. Getting too much vitamin D, especially above 4,000 IU daily, can be dangerous. If you already have osteoporosis, remember that vitamin D and calcium alone cannot treat the disease. You'll need to take them along with other medications your doctor prescribes. Your body doesn't absorb calcium well from foods high in oxalates (oxalic acid), such as spinach. Other foods with oxalates are rhubarb, beet greens and certain beans. These foods contain other healthy nutrients, but they just shouldn't be counted as sources of calcium.
