Does calcium *actually* help to support strong bones and teeth?
Plus, 5 simple ways to increase your child’s daily intake
If you’re a parent, chances are you’ve heard that calcium is important for your kids, but do you know why?
From your child’s very first baby tooth to growing strong, healthy bones, calcium can play a role in supporting growth and development.
According to the Australian Institute of Health and Wellness, around two in five children (42 per cent) have experienced decay in their primary teeth, with one in four (24 per cent) in their permanent teeth, so it’s clear that supporting healthy teeth is something families should keep top of mind.
Similarly, research shows that one third (36 per cent) of injury-related hospitalisations among children and adolescents are due to fractures, highlighting the importance of prioritising healthy bone development from an early age.
So, does calcium really live up to its reputation? Here, we share all the important details, as well as five simple ways to increase your child’s daily intake.
Why does calcium matter?
Calcium is a mineral that helps to support the development of healthy bones and teeth in children. It is particularly important during key periods of growth such as infancy, childhood and adolescence. This is because it helps to support bone strength and structure, plus ongoing dental health.
However, as your child moves through different stages of growth, their daily requirements will change. For parents, that means it’s important to find reliable ways to meet their nutritional needs.

5 simple ways to increase your child’s calcium intake
1. Include calcium‑rich dairy
Milk, yoghurt, and cheese are the familiar go-tos we all know and love, and for good reason. These foods all naturally contain calcium and can be easily included in everyday meals and snacks.
2. Look beyond dairy
However, for children with intolerances or those looking for alternative solutions, leafy greens, almonds, and certain types of fish can also provide calcium, helping to include a well-rounded variety in your child’s diet.
3. Choose fortified foods
Many foods, such as cereals and plant‑based milks, are fortified with calcium. These can also be particularly helpful if your family follows a dairy‑free lifestyle.
4. Make small swaps
Little changes, such as serving oatmeal made with milk instead of water, can quietly increase your child’s calcium intake without causing any fuss.
5. Consider supplements
If you’re concerned about meeting your child’s daily requirements through food alone, supplements can be a great way to help support their calcium intake.
