Increasing daily calcium does not reduce the risk of fractures beyond a certain amount, which is 750 mg per day. Most MDs in the US overdose supplementation, thinking that more is better to prevent or stop the progression of low bone mass...osteopenia and osteoporosis. Studies on more than 60,000 women showed that women had the lowest risk of having a fracture when they consumed about 750 mg of calcium per day. Higher levels of calcium intake had no additional benefit. We know that in women with osteoporosis who we treat with large doses of calcium, especially without sufficient vitamin D, are prone to a higher risk of heart attack and stroke.
