How to Use Collagen for Gut Health

Collagen is the most abundant type of protein found in the human body, as well as a valuable protein that you can get from foods like traditional bone broth and from collagen supplements.

It’s made up of key amino acids including glycine, proline and arginine that aren’t found in high amounts in typical meat protein sources, such as chicken or beef. This explains why many people can benefit from acquiring more collagen, especially considering how it plays a critical role in supporting a healthy gut lining, joint health, skin health and more.

One way to boost gut health is using more dietary collagen. This type of protein accounts for 25 to 30 percent of all the proteins in the human body, since it’s the main component of connective tissues. It helps maintain the structure and function of many different body parts, including the lining of your organs and gastrointestinal tract, plus your bones, joints, ligaments, tendons and skin.

One of the main benefits of collagen for gut health is its ability to support the integrity of the gut lining. Therefore, just about everyone can benefit from collagen foods and powders: infants, young children, the elderly, athletes, pregnant women, new mothers, and adult men and women.

Of course, you should always consult your healthcare professional prior to starting any new dietary or lifestyle regimen, including collagen supplements. Likewise, you should always read and follow label directions for suggested use.

Starting around your late-20s to mid-30s, you typically begin to naturally produce less collagen, which is why you may start to notice it in your skin, joints or even your gut.

Benefits of collagen for the gut

Generally speaking, collagen is one of several gut support supplements that benefit gut health by supporting a healthy gut lining and supporting digestion.

Some general ways it adds to healthy gut function include by:

1. Supports the gut lining

Collagen helps support the gut lining, which aids nutrient absorption and is needed for overall healthy immune function. Collagen helps support the lining of the intestinal wall which is usually bound tightly together, making up what’s called “tight junctions,” leading to an overall healthy intestinal barrier.

2. Helps microbiome

Collagen supports a healthy gut microbiome, which means that you’re able to maintain a healthy intestinal barrier, as well as a healthy ratio of “good guy” to “bad guy” gut flora or beneficial types.

3. Liver detox

Collagen can support normal phase two liver detoxification. What is that? It's a process in which the liver uses one of two major enzyme pathways to alter a potentially toxic substance into a less toxic substance that the body can more easily excrete.

4. Gut–grain connection

Supporting the central nervous system and promoting relaxation, collagen is important for the “gut brain connection.”

5. Supports a healthy weight

Collagen also helps support a healthy metabolism and body composition.

6. Helps energy levels

One of many valuable energy supplements, collagen can aid in energy output.

Which collagen is best for gut health?

Did you know that there are at least 29 different types of collagen found in the human body? These include types 1, 2, 3, 4, 5 and 10, which have different roles such as supporting healthy skin, organ tissue, muscles, arteries, etc.

The best types of collagen for gut health include type 1 and type 2, which are by far the most abundant in your body and needed for healthy organ tissue and other connective tissues, as well type 4, which helps form tissues within the digestive system.

Ideally you want to consume hydrolyzed collagen powder, also called collagen peptides. These contain amino acids and nutrients found in collagen from bone broth, but have undergone a process called hydrolysis to break them down into shorter chains of proteins.

Generally speaking, collagen peptides can be dissolved in both hot or cold water. Because of the hydrolysis process for collagen, they are broken down and digested more easily in your gut.

How to use collagen for gut health

Want to learn how to increase collagen levels? While our bodies make their own collagen, we can also give our bodies the building blocks for collagen production from eating certain foods and taking collagen supplements.

How much collagen do you need for gut health? It really depends on your current health, lifestyle and goals.

For example, you can consume at least one serving of collagen protein powder per day, by having a collagen-filled smoothie for breakfast, while also eating a “collagen-boosting” lunch and dinner to support their gut health and promote healthy connective tissue.

Some people may benefit from having even more, such as 2–3 servings daily ("collagen loading protocol"), but should always check with their healthcare professional first.

Here are the top three things to do in your quest to consume more collagen for gut health:

1. Consume more collagen-rich foods

Incorporate natural, collagen-promoting foods into your diet, especially bone broth that is the most readily available source.

2. Use collagen supplements

Ancient Nutrition's Multi Collagen Protein powder contains 10 types of collagen from four real food sources. In addition, Multi Collagen Protein Gut Restore formula also provides you with one billion CFUs* of soil-based organism (SBO) probiotics, powerful prebiotics and two kinds of glutamine for overall gut support.

You may also be interested in the Multi Collagen Advanced (with specific formulas for leanness, muscle growth, hydration, detoxing and longevity) or the Collagen for Women's Health line (with formulas for hair growth, hormone balance, menopause support and testosterone support.

When it comes to adding collagen protein powder to your diet, there are lots of options for putting it to use. Multi Collagen Protein powder is unflavored (unless you opt for a flavored formula) and can be mixed into coffee, smoothies, juice, soups, or used in oatmeal and healthy baked goods.

3. Eat a well-rounded diet

A good diet — including collagen-boosting foods — should aid the production of the collagen you consume and helps support your body’s ability to make its own collagen. This type of diet should include plenty of antioxidants, vitamin C, zinc, copper and protein in general that all help with collagen synthesis.
