How Collagen Affects Gut Health


Bone broth and gelatin have long been used to heal digestive problems, but scientists have recently uncovered the science behind the nutritional power of these foods – the key is collagen! The unique structural properties and amino acid profile of collagen allows this protein to help in reducing gut inflammation, heal stomach ulcers, aid in digestion, and regulate stomach acid secretion. Scientific research has shown collagen synthesis to be an essential biological process in repairing the intestinal lining. Collagen and gut health are related; read below the benefits of supplementing with collagen for leaky gut and other gut conditions.

Collagen Benefits on Gut Health

Collagen Regulates Stomach Acid Secretion
Collagen has been found to regulate the secretion of gastric juices by ensuring enough acid for proper digestion. Collagen protein also prevents an excess of gastric juices, which can lead to heartburn, stomach ulcers, and other painful digestive problems caused from an overly acidic environment1.

Collagen Can Help Heal Stomach Ulcers
Glycine and Proline, the two main amino acids in Further Food Collagen Peptides, may help heal the stomach lining and prevent stress-induced ulcers through their positive impact on the central nervous system. Studies have identified glycine as an effective inhibitor of stomach ulcers due to its ability to prevent harmful gastric secretions in the stomach lining2.

Collagen Aids in Digestion
Another collagen and gut health benefit is that collagen helps digestion. Because collagen is a hydrophilic molecule, it has an attraction to water and acidic molecules, which aids the digestive process.  Ingested collagen surrounds itself with water and stomach acid as it moves through the GI tract, which assists the breakdown of other proteins and carbohydrates in the intestines. Additionally, by holding water in the intestine, collagen helps move food through the GI tract more smoothly.

Collagen May Helps Repair the Intestinal and Stomach Lining
Want to know how you can heal the intestinal and stomach lining? Try supplementing with collagen peptides! Science has identified collagen synthesis as an important component in the process of repairing and healing the intestinal lining. When there is damage or inflammation to the intestinal lining, new smooth muscle cells are made to heal the stomach lining and the intestinal wall. Scientists have found that collagen production in the intestine is greatest when smooth muscle cells are being generated during healing. Thus, collagen is a key component to healing the intestinal wall. Supplementing with collagen may help to repair and heal the stomach lining. 3

Collagen May Help Heal Leaky Gut and IBS
Have you considered supplementing with collagen for leaky gut? Glutamine, one of the amino acids in collagen, has been identified as the key amino acid for preventing inflammation of the gut wall and healing leaky gut syndrome. It has been linked to inhibiting inflammation and oxidative stress associated with the opening of tight junctions in the connective tissue of the intestinal lining4. Studies have found decreased collagen levels in individuals with digestive imbalances. Specifically, there is an association between inflammatory bowel disease and decreased serum collagen levels5. Supplementation with collagen protein is key to providing relief for digestive diseases.

    I’ve been investigating about the benefits of collagen as I would like to take it for joint and skin care but I ‘ve been diagnosed with chronic gastritis. I’m 50 yrs old and the gastritis symptoms come and go, could collagen help with my condition or at least not make it worse? Thanks.

      Thanks for the question. As is written in this article, collagen can play a role in repairing gut lining, helping digestion and regulating stomach acid. This can all help with gastritis symptoms. While we recommend 1-2 scoops a day indefinitely for maximum benefits, we recommend you consult with your medical care practitioner for personal advice. Wishing you good health.

    I just came upon your brand of collagen. I have been doing a lot of research on Collagen. Everyone says their product is the best. But I feel that is wrong. I am looking for a marine collagen and so far I like what your brand as to say. I have had gut issues most of my life. Actually it is getting better since I have given up almost all carbs, except a few like sweet potatoes and occasionally kasha. Where in North America does your collagen come from?

    what is the difference between Collagen and Gelatine and which is the best for gut and skin benefits .
    Thank You
    Robyn .

      Both Collagen peptides and Gelatin have the same gut and skin benefits since they come from the same source-collagen. The difference is in the use-collagen peptides can be mixed into any food or beverage without added texture, while gelatin “gels” in liquids so it is often used as a thickener to make jello, gummies, and puddings.

    I have had severe IBS/D for years. I am looking for a protein powder that would not make the diarrhea worse. I read that some of the powders make more fluid stay in the colon, so I don’t understand what smoothies with a protein powder would do. The LOWFOD Map diet helps my allergies and I am hoping to add some shakes. Any help will be appreciated. Shirley C

    Which form of collegan helps gut? Type 1 , type 2, type 3 or types 1 and 3 combined in a powder? I got recently some powder and it says its made with 1 &3.

    I can confirm that collagen has done wonders for my stomach. I mix it with glutamine powder and squeeze some lime juice in there (Vitamin C is necessary for collagen digestion).
