If you’ve ever heard the phrase “health starts in the gut,” it couldn’t be more true—especially when it comes to your immune system! About 70% of your immune system lives in your gut, and the balance of your microbiome plays a crucial role in defending your body against pathogens, reducing inflammation, and keeping you vibrant.
But what happens when your gut isn’t in tip-top shape? If you’ve recently tackled leaky gut, you may still need to rebuild your immune function. One key marker on a stool test that tells us about immune health is secretory IgA (sIgA). If it’s elevated, your body is in an active fight mode—like a security alarm going off. But if it’s depleted, it may indicate a long-term burden, leaving your immune system weaker and more vulnerable to infections.
So, how do we replenish and fortify the immune system after healing leaky gut? Let’s dive in!
1. Feed Your Gut for Immune Strength
Your gut microbes thrive on the right kind of fuel. Nourish them with:
✔ Prebiotic foods like asparagus, garlic, onions, artichokes, and flaxseeds to feed good bacteria.
✔ Probiotic-rich foods like fermented veggies, kimchi, sauerkraut, and coconut yogurt to introduce beneficial strains.
✔ Polyphenol-rich foods like berries, dark chocolate, and green tea to support gut diversity.
2. Restore Your Gut Lining
A healthy gut lining is your first line of defense. To repair and strengthen it:
✔ L-Glutamine – An amino acid that fuels intestinal cells and promotes repair.
✔ Zinc carnosine – Supports mucosal healing and reduces inflammation.
Both of which you will find in one of our favorite supplements here at Modern Medicine- GI Integrity.
3. Support Secretory IgA & Immune Resilience
Once your gut lining is strong, it’s time to rebuild immune function:
✔ Reishi, Cordyceps & Turkey Tail Mushrooms – These adaptogenic mushrooms enhance immune response.
✔ Colostrum & Transfer Factors – Help train and support immune modulation.
✔ Vitamin A & D – Key vitamins that regulate immune defense and mucosal health.
✔ Astragalus & Beta-Glucans – Plant-based immune boosters that help your body adapt.
Upgrade Your Immune Support with Transfer Factor Multi-Immune™
One of our favorite immune-supporting supplements at Modern Medicine is Transfer Factor Multi-Immune™. This advanced formula includes bovine-derived transfer factors, whole colostrum, medicinal mushrooms, and immune-supporting herbs. Clinical research has shown that it enhances T-cell activation, natural killer (NK) cell function, and cytokine response—all essential for a well-balanced immune system!
4. Stress Less, Sleep More
Your gut and immune system are deeply connected to your nervous system. Chronic stress depletes secretory IgA, so prioritize:
✔ Deep breathing & meditation to shift your body into rest-and-digest mode.
✔ Daily movement like yoga, walking, or rebounding to enhance lymphatic flow.
✔ Consistent sleep – Aim for 7-9 hours to allow your immune system to recharge.
Final Thoughts
Rebuilding your immune system after healing your gut doesn’t have to be complicated! By nourishing your microbiome, sealing your gut lining, supporting secretory IgA, and embracing lifestyle shifts, you’ll be setting your body up for long-term resilience.
Your gut is your greatest ally—so take care of it, and it will take care of you!
