Children and the Immune System

The immune system is what helps a child fight off foreign invaders that may be harmful to the body, such as bacteria, viruses, and toxins. It is divided into two parts: the innate immune system and the acquired immune system.

Innate Immune System

The innate immune system acts as the first line of defense. The skin, the cornea, and the membranes lining up the different body tracts act as a barrier that helps protect a child from perceived invaders.

The innate immune system is already activated at birth and comprises phagocytes - the invader-fighting cells.

Acquired Immune System

The acquired immune system works hand in hand with the innate system in protecting a child from serious infections. Upon exposure to harmful invaders, the B lymphocyte cells form antibodies that help eliminate specific substances from the body.

This way, the body will recognize once a child gets re-exposed to the same foreign substance signaling the antibodies to fight them off.

What Are The Best Vitamins For Children's Immune System?

How can you be at ease knowing your child spends much time playing outdoors or interacting with other people inside a classroom? How do you make sure that they get the extra protection they need?

Here are the vitamins that can boost your child's immune system.

Vitamin C

This vitamin is also known as ascorbic acid. As it cannot be produced by the human body, it is deemed an essential nutrient. Vitamin C plays a number of roles in bodily processes.

Vitamin C can help strengthen your child's innate immune system and protect them from the harm of free radicals.

Aside from collagen production and protein metabolism, this vitamin is best known for its antioxidative and immune system-boosting properties.

The Recommended Dietary Allowance (RDA) for Vitamin C varies per age and gender. As children are at their most vulnerable, they need to get an adequate amount.

Vitamin A

This fat-soluble vitamin is found as retinol in animal food sources and as carotenoids in plant sources. It has three active forms in the human body: retinol, retinal, and retinoic acid.

Vitamin A plays a significant role in the growth and development of children. It is also involved in the promotion of a healthy vision and strong immune system.

Furthermore, vitamin A deficiency may cause night blindness and dry eyes. In severe cases, it may lead to total blindness. Children who do not get enough Vitamin A are also at risk for contracting infections.

Depending on the age, children are recommended to have a Vitamin A intake of 300-600 μg/day in order to support their needs.

Vitamin D

This vitamin is another nutrient that protects children from infections. Aside from maintaining strong bones, Vitamin D also plays a role in keeping a healthy immune system.

Health research suggests a strong link between Vitamin D and a boost in the immune system of young children.

Adequate exposure to sunlight will make sure your child gets their daily needs. Vitamin D (in the form of cholecalciferol) is produced by the body as ultraviolet B rays hit the skin.

A deficiency of this vitamin may predispose children to autoimmune diseases such as type 1 diabetes, multiple sclerosis, rheumatoid arthritis, and lupus.

It is recommended that children ages 3 to 13 have 600 IU/day of Vitamin D intake.   

Vitamin E

Vitamin E is a fat-soluble vitamin known for its antioxidative properties. Much of Vitamin E is found in immune cells, and clinical studies have proved its vital role in immune function.

Vitamin E is consumed in the α-tocopherol form. Along with Vitamin C, this vitamin prevents cell damage from free radicals. Children can benefit from a strengthened immune system to prevent the development of diseases later on in life.

Depending on the child's age, the RDA for Vitamin E ranges from 6 to 11 mg per day.

Vitamin B6

Another vitamin of note is Vitamin B6 or pyridoxine. A deficiency in this vitamin is said to weaken immune defenses by inhibiting the production of antibodies.

A study showed that insufficient intake of Vitamin B6 impairs immune system function. With this vitamin, children can receive further protection from many diseases.

Depending on a child's age and gender, the RDA for Vitamin B6 ranges from 0.5 mg/day to 1.0 mg/day.

Where Can You Get These Immunity-boosting Vitamins?

Natural food sources

With modernization comes the steady rise of processed and fast food, but these are not good sources of vitamins and minerals.

In addition, a single type of food cannot give your child everything they need to ward off diseases. Adding variety to the diet is key to keeping your child healthy.


Citrus fruits (oranges, grapefruit, lemon) are rich in the immune-boosting Vitamin C. Mangoes and strawberries also contain a significant amount of Vitamin C.


Carrots, squash, sweet potato, and green leafy vegetables are excellent sources of Vitamin A. Red bell pepper and broccoli are abundant in antioxidant vitamins A, C, and E.

Nuts and seeds

Almonds and sunflower seeds are rich in Vitamin E and B6. These excellent snack alternatives can help boost your child's immune system.


That chicken soup can help your child's colds. Chicken and turkey are rich sources of Vitamin B6, which is beneficial to red blood cell formation and reduces inflammation.

Fortified-rich food

Food products such as breakfast cereals, milk, bread, and pasta are fortified with vitamins. Just make sure to check and read the label.

While whole foods are still the best source of immune-boosting vitamins, other factors such as your child's preferences or medical conditions can interfere.

Different forms of supplements are widely available in the market, such as gummies, chewable tablets, powders, and liquid syrup. Some single-nutrient vitamins and multivitamins can help a child struggling with eating a variety of food every day.

However, much caution should be exercised when it comes to supplementation to avoid the risk of side effects from a vitamin overdose. It is best to consult a pediatrician or dietitian for the right supplement and dosage.

More Tips on How To Improve Children's Immunity

Aside from keeping a healthy and balanced diet, below are some tips to improve your child's immunity. 

Proper sleep

Enough sleep enhances both the innate and acquired immune system. The recommended hours of sleep for children ages 6 to 12 are 9-12 hours.

Physical activity

There are health benefits to limiting your child's usage of gadgets and encouraging them to stay physically active. Aside from getting Vitamin D from enough sunlight, exercise can help build a strong mind and body for your child.


It is essential to stay up to date when it comes to your child's vaccinations. Amidst debates over its safety, vaccines recommended by doctors will help your child and others from being infected by preventable diseases.
