Notes

It is essential for children to get adequate amounts of calcium because the teeth and bones are developing at this age. Their bodies will naturally be craving calcium at these ages.

Those taking daily calcium supplements make sure that the supplements you are using also include magnesium, ideally at a 2:1 ratio. So, for every 1000mg of calcium you should make sure you are taking in at least 500mg of magnesium. The body uses magnesium to transport calcium to the cells so most supplements have taken this issue into account.

You cannot overdose on calcium, but some health problems can be caused by ingesting too much calcium. If you overuse calcium it can build up in the bloodstream and cause Kidney Stones when it is filtered out of the body via the kidneys. It is generally considered that it is safe to take in up to 2500mg of calcium daily, but you do not need to take nearly this much to get the benefits of this mineral.

Tips and Cautions on Calcium Intake

You should also work to increase your daily intake of vitamin D by drinking fortified milk, getting more exposure to the sun or taking supplements. Vitamin D helps the body to absorb calcium so it will enter the bloodstream and bones.

Read the instructions and know how to properly take your supplements. For example, supplements that contain calcium and vitamin D should be taken before bed instead of with food so they will absorb properly

Reduce your intake of alcohol, caffeine and sodium. Over-consuming these products can lead to the decreased absorption of calcium and it will be excreted through your kidneys instead.
