What Are Supplements for Leaky Gut?
Supplements for leaky gut support the intestinal lining. This lining is a single layer of cells that decides what passes from the digestive tract into the bloodstream. Proteins called tight junctions hold these cells together. When those junctions loosen, more bacterial fragments and food particles slip through, a state researchers call increased intestinal permeability. Leaky gut supplements supply nutrients and plant compounds that feed the cells of the gut wall, help maintain its protective mucus layer, and support the tight junctions.
Most leaky gut supplements fall into six groups:
- Amino acids. L-glutamine is the main fuel for the cells lining the small intestine, which replace themselves every 3 to 5 days.
- Minerals. Zinc carnosine binds zinc to the dipeptide L-carnosine. This form clings to the stomach and gut lining longer than standard zinc salts.
- Proteins. Colostrum provides antibodies and growth factors. Serum-derived immunoglobulins (IgG) bind microbial toxins inside the gut before they reach the gut wall.
- Herbs. Slippery elm and marshmallow root release mucilage, a gel that coats the digestive tract. Aloe vera inner leaf soothes the stomach and intestinal lining.
- Amino sugars. N-acetyl-glucosamine (NAG) is a building block of the glycoproteins that make up the gut’s mucus layer.
- Postbiotics. Butyrate is the short-chain fatty acid that colon cells burn for energy. In the tributyrin form, it passes through the stomach intact and is released in the intestine.
If you have ongoing digestive symptoms, are pregnant, or take prescription medication, talk to a healthcare provider before starting a supplement.
