What supplements support gut barrier integrity?

Take zinc carnosine (ZnC) at 75mg twice daily for 8 weeks to support stomach and intestinal lining repair. This is a chelated form of zinc specifically studied for GI applications.

Don't rely on apple cider vinegar (ACV) for gut health claims. Despite widespread popularity, there are no clinical trials supporting ACV for gut barrier integrity, microbiome improvement, or digestive function.

Be cautious with the term "leaky gut syndrome" — it's real biology but often oversimplified in wellness marketing. Increased intestinal permeability is a measurable phenomenon, but it's usually a symptom of other conditions rather than a root cause.

Eat 25-35g of diverse fiber daily from whole foods rather than relying on supplements for gut barrier support. Focus on butyrate-producing fibers: oats, cooked and cooled potatoes, green bananas, leeks, onions, and garlic.

Supplement with L-glutamine (5-10g daily, divided into 2-3 doses) if recovering from gut infections, prolonged antibiotic use, or if you have diagnosed increased intestinal permeability.

Take bovine colostrum (3-6g daily) as a supplement to support gut barrier function. Choose a product from grass-fed sources that lists immunoglobulin (IgG) content on the label.
