    • What are vitamins and minerals?

    Vitamins and minerals (Opens in new tab) are nutrients your child's body needs to be healthy and to grow and develop properly. Vitamins and minerals are sometimes called micronutrients. This is because you only need very small amounts in your diet.

    Vitamins and minerals are found in the food you eat and drink. The best way for your child to get enough vitamins and minerals is from a healthy diet.

    Why are vitamins and minerals important for my child?

    Vitamins and minerals are important for your children because they:

    How does my child eat vitamins and minerals?

    Your healthy child can consume enough vitamins and minerals they need by eating a wide variety of foods from the 5 food groups every day. The 5 food groups are:

    1. vegetables — offer lots of vegetables in many colours
    2. fruit — offer fruits of different colours
    3. grain foods — mostly wholegrain breads, cereals, rice, pasta, noodles, polenta, couscous, oats, quinoa and barley
    4. lean meats and poultry, fish, eggs, tofu, nuts and seeds, and beans
    5. milk, yoghurt, cheese and their alternatives

    Your child should also drink plenty of water. Once your child is aged over 2 years, they can be given reduced fat milk.

    The amount of food your child needs from each food group will depend on their:

    • age
    • sex
    • physical activity levels
    • height

    What can cause a vitamin or mineral deficiency?

    Your child can have a vitamin or mineral deficiency if:

    Your child can also develop vitamin D deficiency (Opens in new tab) if they do not get enough sunlight.

    Read about Vitamin D and your health (Opens in new tab).

    If your child has a vitamin or mineral deficiency, their symptoms can vary.

    What if my child has a special diet?

    Your child might need a special diet for many different reasons, including:

    Children who need to follow a special diet may need more vitamins or minerals. If your child is on a special diet, it is important you speak with your child's doctor (Opens in new tab) or dietitian (Opens in new tab). They can give you advice and guidance that is individualised for your child.

    What if my child is vegetarian or vegan?

    A vegan or vegetarian diet (Opens in new tab), if planned carefully, can provide your child with all the nutrients they need to be healthy and grow.

    If your child is on a vegetarian diet, it's possible for them to get all the vitamins and minerals they need by eating dairy products and eggs, as part of a healthy, balanced diet.

    If your child is on a vegan diet, the key vitamin they may not be able to get enough of is vitamin B12. Vitamin B12 is only found in animal foods. Some soy-based foods have vitamin B12 added to them. It is common for vegans to take a vitamin B12 supplement.

    You may need to supplement vitamin B12 and other nutrients.

    Read about vitamin B deficiency (Opens in new tab) and vitamin B and your health (Opens in new tab).

    Other vitamins and minerals that can be difficult to get enough on a vegan diet are:

    • iron
    • zinc
    • calcium
    • vitamin D

    Iron, zinc and calcium are found in:

    • legumes
    • tofu
    • nuts
    • seeds
    • calcium-enriched soy and other plant-based drinks

    Children on a vegan diet who don't eat enough of these foods may also need a supplement to meet their nutritional needs.

    Check with an accredited practising dietitian (Opens in new tab) that your child's diet offers all the nutrients they need for healthy growth.

    Food allergies and intolerances

    Food allergies may also make it harder for your child to get all the vitamins and minerals that they need.

    It's best to talk with your doctor or a dietitian to check that your child has a well-balanced diet.

    When should my child see a doctor?

    You should take your child to see a doctor if:

    • you are worried about their growth and development
    • you are worried they are not getting enough vitamins and nutrients in their diet
    • you would like a referral to a dietitian

    You can also see a dietitian. They can check that your child is getting all the vitamins and minerals they need.

    Should I give my child supplements?

    If your child is healthy and has a balanced and mixed diet, it is unlikely they will be deficient in vitamins and minerals and need supplements.

    If you are considering giving your child supplements, first check with their doctor (Opens in new tab) or dietitian (Opens in new tab).

    They will ask you questions about your child's medical history, their diet and possibly request blood tests (Opens in new tab). This will help them decide if your child will benefit from a supplement and which kind.

    There is a lot of information about vitamin and mineral supplements on social media platforms. Not all the information you come across is correct. For this reason, seeking advice from your qualified doctor, dietitian and pharmacist (Opens in new tab) can help you make the right decisions for your child's health.

    Supplements are not risk-free. Consuming more vitamins and minerals is not always better for you. Too much of some vitamins and minerals can be potentially harmful if your body cannot get rid of them.

    Relying on supplements may give you a false sense of security, for example if your child eats a lot of junk food (Opens in new tab). Adding supplements to a poor diet does not make it healthy. Supplements can also be expensive.

    If your child is recommended to take supplements, read the label and follow the instructions you were given. Your local pharmacist can also explain how to safely give your child their supplement.

    In Australia, the Therapeutic Goods Administration (Opens in new tab) (TGA) checks all supplements for safety and quality.

    Vitamin K for newborns | NHMRC

    Vitamin K helps blood to clot. Administering vitamin K soon after birth prevents serious bleeding in infants. By the age of around 6 months, infants have built up their own supply of vitamin K. An NHMRC joint statement recommends that all newborn infants receive vitamin K.
