Calcium is the most abundant mineral in the body. Calcium isn't just necessary for healthy bones - it's also required for healthy blood circulation, nerve impulse transmission, muscle contractions, and cell metabolism.

Research has also demonstrated that calcium may reduce the risk of osteoporosis. Osteoporosis affects middle aged and older persons. 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.

Most diets don't meet the body's need for calcium. Most Americans above the age of 9 don't get the calcium they need through diet alone. Supplementation with a readily absorbable calcium that combines magnesium and vitamin D can help fill the nutritional gaps often seen in the average diet.
