Collagen and gut health: How are they connected?

What makes your stomach feel the best?

Research into gut health is growing at a record pace. But did you know that a completely common protein – collagen – could play an unexpectedly important role for your gut? If you think collagen is only about skin and beauty, it’s time to discover a new side of this super protein.

The role of collagen in the body: more than just skin

Collagen is the body's most abundant protein. It acts as the glue that holds tissues, muscles, skin and organs together. But collagen isn't just found in joints and the face – it's also essential for the structure and function of the gut. Researchers have identified that the lining of the gut is largely made up of collagen-rich structures that protect and repair the gut wall.

When collagen in the gut breaks down or decreases, the protective ability of the mucosa also decreases. This can increase the risk of intestinal health problems, such as leaky gut and inflammation. By adding collagen through diet or supplements, you can show your gut a little extra care.

How does collagen support your gut health?

The gut is a delicate environment where thousands of factors affect the balance. Collagen excels in several ways when it comes to supporting the stomach and intestines:

• Strengthens the intestinal wall: Collagen builds up and strengthens the intestinal barrier, making it more difficult for harmful substances to enter the bloodstream.
• Promotes healing: In the event of irritation, inflammation or minor injuries, collagen helps repair the intestinal cells and mucosa.
• Optimizes digestion: Certain amino acids in collagen stimulate the production of stomach acid and digestive enzymes, necessary for good digestion.
• Supports intestinal flora: An intact intestinal wall benefits the good bacteria and contributes to a balanced microbiome.

What does the research say about collagen and digestion?

Scientific research has shown that supplementing with collagen can improve gut health in several ways. For example, several studies have noted that people with IBS and similar digestive disorders often have lower levels of collagen in their intestines. Other research reviews suggest that supplementing with collagen can promote the regrowth of cells that line the gut wall.

Amino acids such as glycine, proline and glutamine are particularly important for rebuilding a healthy mucosa and supporting the immune system in the intestine. Several users also report reduced symptoms from acid reflux as well as diarrhea and constipation when regularly taking collagen.

Natural sources of collagen – and why supplements may be needed

The best way to increase your collagen intake is through your diet. Traditional bone broth, chicken skin, and fish are excellent sources. But we don't always get enough. Stress, age, and a Western diet all contribute to collagen levels decreasing over time. Therefore, a quality supplement can be an easy and safe way to support your gut.

We have chosen to offer collagen supplements in our store that also contain prebiotics – i.e. nutrition for the good bacteria in the gut for a double effect. Check out our collagen product for better gut health here and experience the difference – your gut will thank you!
