Which vitamins are important to children's health?

Happy family

A varied and balanced diet is the best way for children to get the vitamins and minerals they need. However, getting them to eat lots of different healthy food is easier said than done. To ensure that they get enough of the nutrients they need to grow and develop correctly, the Department of Health recommends that all children aged between 6 months and 5 years take daily supplements containing vitamins A, C and E.

Vitamin C – Vitamin C is essential for children's general health because it protects cells and keeps them working correctly. It also supports their immune system and helps with iron absorption.

Vitamin A – This is necessary for a robust immune system, helps with eyesight in low light and boosts skin health.

Vitamin D – Created when sunlight falls on our skin, vitamin D is vital to keep bones healthy and regulates the level of minerals in your cells.

Children need the same vitamins and minerals as adults but in smaller measures. The right nutrition is essential to support bone health, growth and brain development. This requires a broad range of other nutrients, including:

B vitamins - B vitamins are needed for the production of red blood cells, maintaining a healthy heart, and nervous system.

Vitamin E – Vitamin E strengthens children's immune system and has many other uses, including keeping blood vessels open.

Calcium – This helps children develop strong bones and may prevent bone loss later in life.

Iron – Iron is used in red blood cells to help transport and store oxygen.

Zinc – Zinc supports wound healing and is also used in building protein and DNA.

What are omega 3-6-9 fatty acids and what do they do?

Fatty acids omega 3, omega 6, and omega 9 are long-chain molecules that form the building blocks of unsaturated fats. They're needed for a wide variety of functions, from energy storage and muscle activity, to eye health and cell growth. Omega 3 and 6 are considered 'essential' and need to be obtained through diet because they can't be made in the body. Omega 9 can be made in the body, but foods that contain it can be used to supplement this.

Omega 3 – This fatty acid is essential for brain health and several vital eye structures. Without it, early development can be impaired and lead to health complications later in life. Studies have also found that omega 3 can help to keep your heart healthy. The three types are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

Omega 6 – Like omega 3, omega 6 contributes to brain health and normal development. There are four types; linoleic acid (LA), arachidonic acid (ARA), gamma linoleic acid (GLA), and conjugated linoleic acid (CLA).

Omega 9 – Some omega 9 fatty acids, such as oleic acid, have been linked to health benefits such as optimal brain function. There are many different types of omega 9, including oleic acid from olive oil and erucic acid from rape seed oil.

Omega 3 and omega 6 are most often used in supplements for children because of their role in development and brain function. We've chosen to stock Children's Fish Oil from G&G Vitamins because it's an excellent source of omega 3 (EPA and DHA)

Choosing the right vitamins

Mother daughter

There are lots of vitamins marketed for children, but it can be hard to determine which are high-quality and which could be a waste of money. When shopping for children's supplements, it's important that you only buy those that are made for children and don't contain extra-large measures of nutrients. Because children require less than adults, in some cases, taking too much can be dangerous.

Be sure to read the label carefully and look out for:

  • Low sugar options – Some brands opt to use sugar and flavourings to make multivitamins more attractive to children. However, those that keep sugar low and use natural sweeteners are healthier in the long run.
  • How easy they can be absorbed – Vitamins and other active ingredients can come in many different forms and some are easier to absorb into your bloodstream. Wholefood vitamins that provide vitamins and minerals in the form of real fruits and vegetables are usually easier to digest and provide a broader range of valuable nutrients.
  • Official certifications and memberships – Look for products or brands that are members of official organisations or have received relevant awards, such as organic certification. This gives you extra reassurance that they've had to meet official standards from independent organisations. Organic products have to undergo rigorous inspection before they're verified.

It's also worth avoiding:

  • Ferrous sulphate – Iron in the form of ferrous sulphate has been found to build up if taken too often and can become toxic.
  • Chemical additives and artificial fillers – Some products are made with artificial binders and fillers that add no nutritional value. Completely natural products are a much better option and, in some cases, can reduce the risk of side effects.


  • Vitamins should be kept out of reach of children.
  • Keep the supplements away from sunlight, excessive heat and humidity.
  • If your child has any allergies, it's essential that you check the label thoroughly before use.
  • Food supplements should not be used as a substitute for a varied diet or healthy lifestyle.
  • Do not exceed the recommended daily serving suggestion.
