% of calcium absorption Spinach Calcium carbonate Milk CCM When compared to other common sources of calcium, calcium citrate malate is shown to be more absorbable. Calcium citrate malate (CCM) is one of the most absorbable and effective sources of calcium which helps support bone density. Adequate calcium in a healthy diet throughout life may reduce the risk of osteoporosis. Studies in post-menopausal women over the age of 55 demonstrate CCM results in 70% less bone loss when compared to a diet without calcium supplementation and 40% less bone loss when compared to a diet with ordinary calcium supplementation.

May reduce the risk of osteoporosis
