Can Collagen Help Heal the Gut?

The Gut–Collagen Connection

Collagen isn’t just for skin, hair, and joints—it’s also a key player in maintaining a healthy gut. The lining of your digestive tract is made up of connective tissue that relies heavily on amino acids found in collagen, such as glycine, glutamine, and proline. These nutrients help maintain the structure and integrity of your intestinal wall—the critical barrier that keeps toxins out and nutrients in.

When that barrier becomes weakened, it can lead to what’s often called “leaky gut,” a condition linked to inflammation, food sensitivities, and discomfort. By replenishing collagen, you give your gut the raw materials it needs to rebuild and strengthen itself.

How Collagen Supports Gut Lining Repair

1. Strengthens the Intestinal Wall - Collagen provides structural proteins that reinforce tight junctions between intestinal cells, helping prevent unwanted particles from leaking into the bloodstream.

   
   

2. Promotes Tissue Repair - The amino acid glycine in collagen helps repair damaged connective tissue, soothing an irritated or inflamed gut lining.

   
   

3. Supports Mucosal Health - Collagen’s building blocks support the production of the protective mucous layer that lines your intestines, improving comfort and reducing irritation from acidic or spicy foods.

   
   

4. Reduces Inflammation - By supporting healthy gut barrier function, collagen indirectly helps calm systemic inflammation that can stem from digestive dysfunction.

Best Sources of Collagen for Gut Health

• Collagen Peptides / Hydrolyzed Collagen: Easy to digest and absorb; mix into smoothies or coffee.

• Bone Broth: A natural source of collagen, gelatin, and minerals that nourish the gut lining.

• Vitamin C–Rich Foods: Collagen synthesis requires vitamin C, so pair your collagen supplement with citrus, berries, or leafy greens.

How to Take Collagen for Gut Support

For gut health benefits, consistency is key. Aim for 10–20 grams of collagen peptides daily, ideally alongside a meal. Combine with other gut-nourishing nutrients—such as L-glutamine, slippery elm, marshmallow root, or GutGard® DGL licorice—to enhance repair and comfort.

The Bottom Line

Collagen is more than a beauty supplement—it’s a powerful ally for your digestive system. By reinforcing the gut lining, supporting tissue repair, and reducing inflammation, collagen helps restore balance and comfort from the inside out.
