Calcium and Magnesium
There's good evidence to show maintaining a high dietary intake of calcium will help to slow down the process of bone loss and the DoH recommends that women should have an intake of up to 1200mg of calcium per day.
However, calcium is not the only important nutrient as it's been found that there is a clear link between magnesium intake and bone mass density too. Since 7 out of 10 women have diets providing less than the recommended amount of magnesium it makes sense to include this mineral in any bone health programme.
