If you suffer from seasonal allergies, chances are you’ve tried all the usual remedies—antihistamines, nasal sprays, eye drops, and maybe even allergy shots. But there’s one area that might not be on your radar yet: your gut.
It might sound surprising, but more and more research is pointing to a strong connection between gut health and the immune system—especially when it comes to allergic responses. So, can improving your gut health actually help with seasonal allergies? The short answer is yes.
The Gut–Immune Connection
Your gut does a lot more than digest food. In fact, it’s home to around 70% of your immune system. That means it plays a central role in how your body responds to allergens, including the pollen that triggers sneezing, watery eyes, and other classic springtime symptoms.
When your gut is in balance—with a diverse and thriving population of “good” bacteria—it can help regulate your immune response and keep inflammation in check. But when your gut is out of balance, it can tip your immune system into overreactive mode, making you more prone to allergic symptoms.
Studies have found that people with allergic diseases often have a different gut microbiome composition compared to those without allergies. In other words, certain imbalances in gut bacteria may play a role in immune dysfunction—and potentially make seasonal allergies worse.
On the flip side, a healthy gut microbiome may help modulate your immune system, leading to fewer or milder allergic responses.
So What Can You Do?
Improving your gut health doesn’t require a total lifestyle overhaul. Here are a few steps you can take to support your microbiome—especially during allergy season:
-
Eat more fiber: Prebiotic fiber (found in foods like oats, bananas, garlic, and onions) helps feed the good bacteria in your gut. You can also try our Fiber Gummy or Daily Fiber + Digestive Enzymes.
-
Add fermented foods: Foods like yogurt, kefir, kimchi, and sauerkraut are rich in probiotics that can help restore microbial balance.
-
Try a daily probiotic: A high-quality supplement can help diversify your gut microbiome. Our Daily Pre + Probiotic + Herbs is more than just a probiotic, it's a blend of probiotics, prebiotics, and gut-soothing herbs.
-
Limit processed foods and added sugar: These can disrupt gut balance and promote inflammation.
-
Stay hydrated and get good sleep: Both play an important role in keeping your gut—and your immune system—functioning well. Our Stomach Recover + Hydrate and Sleep Support can help and go a long way towards improving your immune system.
The Bottom Line
While we still need more research to fully understand the link between gut health and allergies, the evidence so far is promising. Since your gut plays such a central role in your immune function, supporting it with the right foods and habits could help you feel better—not just during allergy season, but all year long.
And if it means fewer tissues and less time sneezing? It’s worth a try.
