High Quality Gut Support Supplements

Typically L-glutamine, zinc carnosine, slippery elm, marshmallow root, deglycyrrhizinated licorice (DGL), N-acetyl glucosamine, and quercetin. These soothe the lining, support mucosal repair, and modulate the gut immune response.

4–12 weeks for noticeable change in symptoms. Pair with diet adjustments (removing common triggers, adequate fiber, fermented foods) for best results. Long-term use is fine if symptoms keep recurring without it.

Most are best taken on an empty stomach (15–30 min before meals) so the soothing herbs coat the lining. Read your specific product's instructions.

Probiotics add bacteria; gut support formulas focus on the gut lining itself. The two are complementary — heal the lining first with gut support, then build flora with probiotics. Some products combine both, but separating them allows better dose tailoring.

'Leaky gut' (intestinal permeability) is real and is what these formulas target. L-glutamine, zinc carnosine, and demulcent herbs have evidence for tightening junctions and reducing inflammation. Results show up over 4–12 weeks alongside dietary triggers being removed.

Yes — DGL and zinc carnosine specifically have evidence for soothing reflux and supporting ulcer healing. Slippery elm and marshmallow root coat irritated tissue. Many people find these gentler than long-term acid blockers.

Digestive enzymes help you break down food during meals (taken with food). Gut support formulas heal and protect the lining (taken between meals). Both can be used together if you have both maldigestion and lining damage.

Generally before, or simultaneously. Probiotics work better in a less inflamed gut. Functional medicine often follows a 5R approach — Remove, Replace, Reinoculate, Repair, Rebalance — where 'Repair' (gut support) precedes deeper microbiome work.
