Oral Supplements May Promote Gut Health
In inflammatory digestive conditions, such as irritable bowel disease (IBD), there is a “gut healing” theory about collagen. “Some research finds that collagen levels are decreased in patients with these conditions. By taking collagen, you would help correct a deficiency,” says Lachman.
Research published in May 2017 in the journal Alimentary Pharmacology and Therapeutics found that among IBD patients, there was an imbalance between the formation and breakdown of collagen fibers, and this was connected to inflammation. Past research also shows that IBD patients have decreased serum levels of type 4 collagen. Collagen is a part of connective tissue, which makes up your colon and GI tract, so by bringing your levels up, there may be a supportive environment for your body to heal. This is an emerging idea, she says, but it may be one benefit to trying a supplement or dietary approach to increase collagen intake.
