Vitamin A is a fat-soluble vitamin that occurs in most foods available around us. It is vital for maintaining a child’s vision, immune system, and development. Most children get enough from an appropriate balanced diet. The guide below gives details on vitamin A benefits for children, sources of vitamin A, needs based on age, and how high-dose vitamin A supplementation is different from usual supplementation.

Why Do Kids Need Vitamin A?

Vitamin A plays an important role in more than just good vision. It has many roles during childhood.

1. It supports healthy vision

Vitamin A facilitates the maintenance of normal vision. Besides, vitamin A is responsible for the health of the cornea in the eyes. It is extremely essential for sight in low-light conditions. In case of vitamin A deficiency, there might be problems with night vision.

2. It supports the immune system

The immune system of the child works continuously and protects the body from infections. Vitamin A helps in the maintenance of a normal immune system. Vitamin A deficiency in children may make some infections more dangerous, even leading to diseases like measles.

3. It supports growth and development

During childhood, children’s bodies develop actively. There is rapid cell division and further maturation throughout childhood. Vitamin A supports bone development and cell growth. Besides, it facilitates the normal work of several organs. It also supports normal vision and helps maintain a healthy immune system. 

Best Vitamin A Foods for Kids

Most kids get enough vitamin A when eating a balanced diet. The important thing here is to eat a variety of foods as opposed to only one.

There are two types of sources for vitamin A. The preformed vitamin A is already present in a usable form, and the provitamin A carotenoids are plant pigments that the body converts to vitamin A. Beta-carotene is the most common provitamin A carotenoid in foods. 

1. Orange and yellow foods

When planning vitamin A rich foods for kids, think bright orange and yellow foods.

For example:

  • Carrots
  • Sweet potatoes
  • Pumpkin
  • Winter squash
  • Mangoes

This is because they have carotenoids that can be converted to vitamin A. One does not have to make every meal orange in colour. Including them in the meals can help to create variety in kids’ diets.

Use grated carrots in making parathas, add pumpkin to dal or khichdi, or eat mangoes as fruits.

2. Leafy green vegetables

Green vegetables are also a source of provitamin A carotenoids.

Some good choices are:

  • Spinach
  • Kale
  • Broccoli
  • Other dark green leafy vegetables

One could add spinach to a dal, cheela, paratha, or vegetable stuffing, making it simpler to introduce without turning each meal into a debate. A diverse diet is much better than focusing on a so-called superfood.

3. Eggs, dairy and other animal foods

Preformed vitamin A is easily found in animal foods. They include products like eggs and dairy products like milk and cheese.  Some types of fish and organ meats are also very good sources of vitamin A. 

However, there is no need to include only those foods in children’s meals on a daily basis. Plant products will be able to provide provitamin A carotenoids as well. While the body converts plant-based carotenoids into usable vitamin A, animal-source vitamin A is already in its active form. 

How Much Vitamin A Does My Child Need?

The requirements for vitamin A intake change according to age. Recommended dietary allowances (RDA) provided by the NIH are in micrograms of Retinol Activity Equivalents or mcg RAE.

It is necessary to use RAE because vitamin A comes in different forms and is utilised differently.

Age groupRDA (mcg RAE/day)Tolerable Upper Limit (mcg/day)
Children 1–3 years300 600 
Children 4–8 years400 900 
Children 9–13 years600 1,700 

* The Upper Limit applies only to preformed vitamin A, that is, the vitamin A obtained from food, beverages, and supplements. It does not apply to beta-carotene and other provitamin A carotenoids.

Please note that these are reference intakes per day. They are not recommended dosages for supplement intake.

High-Dose Vitamin A Supplements: Why Are They Different?

This is the point when things get complicated. You probably must have come across vitamin A drops with 100,000 or even 200,000 IU of vitamin A in various public health messaging. This dosage is applied in some particular public health programs.

According to WHO guidelines, 100,000 IU of vitamin A is administered to children aged 6-11 months old. Children aged 12-59 months may get 200,000 IU once every four or six months, only in communities where vitamin A deficiency in children is a public health concern.

These are not regular vitamin A supplements. The dosage and the time of administration are determined specifically for certain populations and should be done by a health program or under the supervision of a healthcare provider.

Vitamin A is a fat-soluble vitamin. The body stores it, which is why an overdose of preformed vitamin A could be dangerous.

The recommended Upper Limit by the NIH for children is 600 mcg for 1-3-year-olds, 900 mcg for 4-8-year-olds, and 1,700 mcg for 9-13-year-olds. Therefore, you should not give your child an overdose of vitamin A supplement.

It becomes even more critical if your child takes other supplements. Multivitamins usually contain vitamin A, and the combination of supplements would result in a higher intake of the vitamin. The excess amount of vitamin A is not always beneficial. The aim is to ensure its intake covers all nutritional requirements.

When Should You Talk to a Doctor?

Parents must not suspect vitamin A deficiency in children just based on one symptom. The signs may include vision problems in low-light conditions and issues related to a weakened immune system. In addition, there are numerous other possible causes of poor growth.

A paediatrician should evaluate the situation.

Some children might be at a higher risk of deficiency because they follow a highly restrictive diet or suffer from conditions affecting the absorption of nutrients. These children can include those who are suffering from conditions like coeliac disease and cystic fibrosis.

Consult your child’s doctor before giving any vitamin A supplement apart from the normal one recommended by age.

The Bottom Line

Vitamin A is an essential component in a child’s daily nutritional needs. For children who are generally healthy, a balanced and varied diet is enough. Include colourful vegetables, leafy greens, fruits, eggs, and dairy. If your child does not usually eat healthy, has malabsorption issues, poor growth, or other symptoms, then see a paediatrician.

For vitamin A, satisfying the requirements is more important than trying to exceed them.
