As back-to-school season arrives, parents everywhere start thinking about how to keep their kids healthy. Between classrooms, playgrounds, and playdates, children are exposed to all sorts of germs—and while catching the occasional cold is part of building a strong immune system, there are many ways you can support your child’s body to fight off bugs more effectively. The key? Nutrition, supplements, and most importantly—gut health.
Why Gut Health Matters for Immunity
Did you know that about 70% of the immune system lives in the gut? The trillions of bacteria in your child’s digestive system play a major role in training the immune system to respond to threats appropriately. When the gut is balanced with “good bacteria,” it supports digestion, nutrient absorption, and immunity. When it’s out of balance, kids may be more likely to experience frequent colds, tummy troubles, or even skin issues.
By nurturing gut health through the right foods and supplements, you can set your child up for fewer sick days and more energy to thrive at school.
Foods to Strengthen Your Child’s Immune System
1. Colorful Fruits and Veggies
Brightly coloured produce is full of immune-boosting vitamins and antioxidants. Oranges, strawberries, and bell peppers are rich in vitamin C, while carrots, sweet potatoes, and spinach provide vitamin A to keep immune cells strong. Aim to get a rainbow of colors on your child’s plate each day
2. Probiotic-Rich Foods
Fermented foods like yogurt with live cultures, kefir, sauerkraut, and miso can help populate the gut with good bacteria. For kids who are picky, even a daily serving of plain yogurt with fruit can make a big difference
3. Fibre-Rich Foods
Whole grains, beans, apples, and pears contain prebiotic fibre that feeds the good bacteria in the gut. This keeps the microbiome balanced and supports overall immunity
4. Protein-Packed Meals
Lean meats, eggs, beans, lentils, and nut butters provide amino acids that the body needs to make antibodies and repair tissues. A steady intake of protein is essential for resilience. PS-- For healthy family recipes to go with your natural lifestyle, visit Mama Bare Wellness.
5. Healthy Fats
Omega-3 fatty acids, found in salmon, chia seeds, flaxseeds, and walnuts, help regulate inflammation in the body and keep immune responses in check. If your child isn't a fan of these foods, try a fish oil supplement
Helpful Supplements for Kids’ Immunity
While food should always come first, supplements can fill in nutritional gaps—especially during the busy school year when mealtime isn’t always perfect. Talk to your pediatrician before starting new supplements, but here are some commonly recommended options:
-
Probiotics: A daily kid-friendly probiotic can support gut health and immunity, especially if your child doesn’t eat many fermented foods
-
Vitamin D: Many children are low in vitamin D, particularly in the winter months. This vitamin plays a key role in activating immune defenses
-
Vitamin C: Great for immune support, especially during cold and flu season. A chewable or gummy form is often easiest for kids
-
Zinc: Important for wound healing and immune cell development. Some kids may get zinc through foods like pumpkin seeds, beans, and meat, but a supplement may help if intake is low
-
Elderberry: Often used during cold and flu season, elderberry syrup or gummies can help reduce the severity and duration of illnesses
Lifestyle Habits that Support Immunity
Beyond diet and supplements, everyday habits make a big difference:
-
Sleep: Kids need 9–12 hours of sleep depending on their age. Rest is when the body repairs and strengthens immunity
-
Hydration: Water helps flush out toxins and keeps mucous membranes moist to defend against germs
-
Movement: Daily exercise supports circulation and immune system function
-
Handwashing: A simple but powerful way to reduce germ spread at school
- Stay clear of chemicals in skin care and home products, like fragrance, parabens, dyes and SLS, as they can weaken the immune system. Dimpleskins Naturals has a great selection of non-toxic, chemical-free balms for all ages
Final Thoughts
Boosting your child’s immune system doesn’t mean avoiding all germs—exposure helps their bodies learn and grow stronger. But by focusing on gut health, nutrient-rich foods, and supportive supplements, you can help your kids bounce back quickly, minimize sick days, and feel their best this school year.
