Best Functional Foods for Immune Function in 2025

Tip: Add a tablespoon of sauerkraut or kimchi to meals or take a probiotic yogurt every day.
2. Mushrooms: Nature’s Immune Boosters
Medicinal mushrooms such as shiitake, maitake, turkey tail, and reishi are rich in beta-glucans, immune-stimulating polysaccharides. They’re also antiviral and anti-inflammatory.
Top pick: Mix reishi mushroom powder into your smoothies or soups for an everyday immune kick.
3. Citrus Fruits: Vitamin C All-Stars
You can’t discuss Top Functional Foods without a mention of citrus fruits. Oranges, grapefruits, lemons, and limes are packed with vitamin C, which boosts the level of white blood cells and fights infections.
Quick fix: Begin your day with a warm glass of lemon water or a citrus smoothie.
4. Turmeric: The Golden Anti-inflammatory
Curcumin, the bioactive ingredient in turmeric, is a powerful antioxidant and anti-inflammatory compound. It has been proven to boost antibody responses and regulate immune cell function.
2025 spin: Make lattes with turmeric-infused milk or stir in fresh turmeric root into your juices and stews.
5. Ginger: Antioxidant and Antiviral Champion
