What is Bone Mass?

This is the weight of bone (bone mineral level, including calcium) in the body.

Calcium requirements: Less than half of all Australian adults get their daily recommended intake of calcium.

Calcium is essential for building and maintaining bone. It combines with other minerals to form the hard crystals that give bone its strength. Almost all the body’s calcium (about 99%) is found in the bones.

The remaining 1% is dissolved in blood and other fluids which is essential for maintaining healthy functioning of the heart, muscles, blood and nerves.

Our bodies cannot make calcium, so it must come from our diets. When you are not getting sufficient amounts of calcium in your diet, some of the calcium crystals in bone dissolve and give their calcium back to the bloodstream. Bones therefore act like a calcium bank, storing calcium and releasing it into the blood stream when needed. So if your calcium intake is too low and there are more withdrawals than deposits from your calcium bone bank, you risk losing bone strength.

What is a serve of Calcium and can supplements assist?
If you cannot get enough calcium in your diet, it may be suggest that you take a calcium supplement.

An extra 500-700mg of calcium per day is sufficient for most people. Many companies now provide calcium tablets which also have vitamin D. Vitamin D helps the absorption of calcium from the gut. This is useful if you are vitamin D deficient.
