Calcium is a mineral supplement emphasizing key nutrients for the support and maintenance of healthy bone and bone structure. Research has shown that supplementing with calcium may reduce the risk of osteoporosis. Osteoporosis is a disease, which frequently affects Caucasian and Asian women during their teen and early adult years. Osteoporosis also affects middle-aged and older persons as well as individuals with a family history of the disease. A lifetime of regular exercise and a healthy diet that includes calcium builds and maintains good bone health and may reduce the risk of osteoporosis later in life. Daily intakes above 2,000 mg are not likely to provide any additional benefit to bone health. According to the National Institutes of Health (NIH), osteoporosis is a major public health threat for an estimated 44 million Americans. While an adequate intake of calcium during childhood is known to prevent the disease, the NIH recommends adults take 1,000 to 1,200 mg daily to reduce further bone loss and prevent osteoporosis-related fractures.1 Calcium contains tricalcium phosphate, the exact calcium compound found in bones, vitamin D, phosphorus, and magnesium.
