What are the best vitamins for children’s immune systems?

Vitamin C

Vitamin C is a powerful antioxidant that strengthens our immune system by protecting our cells from harmful free radicals that can suppress the body’s defenses against disease and infection.

It’s a great immune booster for children and can be found in foods like citrus fruits, papaya, strawberries, broccoli, kale, peppers, and more.

Vitamin D

Also known as the sunshine vitamin, vitamin D is essential for the human body to function properly.

It helps regulate hormonal balance and provides a healthy immune system, which is key in preventing illnesses like bronchitis or pneumonia.

Kids need vitamin D all year round, and it’s best to get vitamin D from natural sources like the sun. But if you live in an area where the rainy seasons or winter seasons are long, you may want to consider giving your child a vitamin D supplement.


Zinc boosts the immune system by increasing the body’s production of white blood cells, which fight illness and infection.

It can be found in food sources like oysters, red meat, beans, eggs, and pumpkin seeds.

This mineral usually works best when combined with other vitamins and minerals for boosting the immune system, such as iron or selenium.


Approximately 70 percent of our immune system is in our gut.

Studies have shown that giving kids probiotics either through food sources or supplements can help strengthen the immune system and even prevent infections from occurring, such as colds or flu.

Probiotics are beneficial bacteria that live in the gut and one of the best immune boosters for our health.

They help keep harmful or unwelcome bacteria from growing and can improve digestion and overall immune health.

One way to get more probiotics in your diet is by eating fermented foods like yogurt, kefir, kimchi, sauerkraut, miso, or tempeh.

Omega fatty acids

Omega fatty acids are great for kids because they help fight inflammation in the body, which is a leading cause of illness.

Good food options include salmon, tuna fish, sardines, mackerel. Plant-based sources include walnuts, sunflower seeds, chia, and flaxseeds.

What to look for in a children’s immune-boosting supplements?

In addition to the vitamins and minerals provided in the supplements, here are some other important criteria to consider when purchasing:


Make sure you choose the age-appropriate dosage for your child. Children’s supplements are typically formulated for toddlers, primary school ages, and teens.

Follow the product guidelines and speak with your doctor to ensure the product or dosage is appropriate for your children.

You should also always ask about potential drug interactions before taking any supplements and medications together.

Quality Ingredients

Always check the supplement label and choose one that is made of high-quality ingredients.

Avoid supplements if they:

  • contain artificial flavors or colors
  • have a high sugar content and are sweetened with aspartame, sucralose, saccharin, sorbitol, or mannitol.

If you cannot find adequate information on labels to determine which ingredients are safe, you can always check the manufacturer’s website.


Children’s supplements come in a variety of forms, including chewable tablets, liquids, powders, or gummy bears.

This is helpful for parents as it provides a range of flavors and textures, which makes it more likely for their children to take the supplement.
