What percentage of compact bone is calcium?

Bone is approximately 60 to 70 percent inorganic mineral and 10 percent water by weight. The remaining 20 to 30 percent of bone is organic matrix (osteoid), such as collagen and proteoglycans. Your body contains 1 to 2 kilograms of calcium and nearly 600 grams of phosphorous.
