What is the best collagen for gut health?

Supplements containing collagen are becoming increasingly popular as we try to maintain good health and prevent the effects of aging.

The most commonly used types of collagen are hydrolyzed and gelatinized. The former has smaller molecules than the latter, which can be absorbed better by the body. Aside from collagen supplements, this substance is also found in skin care items and many other food products such as waffles, ice cream, and even chocolate bars.

Today, people are becoming more aware of their health, especially with regards to gut health. As a result, demand for collagen as a food or supplement additive is also on the rise. In this article, we will outline the different benefits of collage and zero in on what type of collagen for gut health you should be using.

What Is Collagen and What Are Collagen Types?

Collagen is the most abundant protein in the human body, comprising 25% of all proteins. It is a major component of skin, bone, tendon, cartilage, and the growth plate.

There are three types of collagen found in the body: Type I and Type III, in addition to type II. Type III is found in the skin, bones, and joints and is also known as collagen type I.

The other two types are different forms of type II collagen. Type II is also found in bone joints as well as the tendons, cartilage and ligaments. It can also be found in epithelial tissue like the heart, blood vessels, lung, intestines and even the cornea of the eye.

Let’s take a closer look at each collagen type:

Type I

Type I collagen is the most abundant type of collagen in the human body. It makes up about 80% of all types of collagen, and it is found in skin, tendons, ligaments, bones, and cartilage.

There are two main types of Type I collagen: fibrillar and fibrous. Fibrillar Type I collagen is found in bone and tendon, while fibrous Type I collagen is found in connective tissue such as ligaments and cartilage.

The benefits of this type include helping to make up bones, teeth, and nails; providing strength to joints; helping wounds heal; and protecting against certain diseases such as osteoarthritis or rheumatoid arthritis

Type II

Type II collagen is a type of collagen that is found in the dermis. It is responsible for providing strength and flexibility to connective tissue. This type of collagen is also found in tendons, cartilage, bone, and skin. The main benefits of this type of collagen are its ability to support the body’s structure and help it maintain elasticity.

Type III

Type III collagen is found in all connective tissues. It helps to regulate cell behavior, including the growth of new cells and the removal of old ones.

In addition, it helps to form scar tissue after injury or surgery. Type 3 collagen for gut health is also one of the most explored areas in this emerging field of gut health study.

Type IV

Type IV collagen is found in the extracellular matrix and binds cells to each other. It is found in all connective tissue, including ligaments, tendons, heart valves and vessels, skin, cartilage, bone and dental tissue.

It can also be found in the cornea and corneal stroma. The main function of type IV collagen is to provide strength and stability for tissues and organs.

Type V

Type V collagen is the least common of the types of collagen, but it’s still important for the body. It is found in both the skin and the blood vessels, and it helps to make up a network of blood vessels called the plexus.

The plexus forms a kind of mesh that helps to hold together the layers of tissue in our bodies. It also helps blood vessels to expand and contract as needed when your heart pumps blood through them.

Because it’s so important for this kind of flexibility, type V collagen is often used in cosmetic products like wrinkle creams and anti-aging treatments.

Type X

Type X collagen also found in cartilage, tendons, bones and ligaments. The primary function of this type of collagen is to provide structural support to the body’s connective tissues.

It is made up of three alpha chains that form a triple helix structure that can be found in many connective tissues throughout the body.

The main benefit of type X collagen is that it helps keep the body’s connective tissues strong and healthy by keeping them flexible so they can move around freely without breaking or tearing apart at any point during their active lives.

How Collagen Supplements Are Beneficial for Your Health

Today, collagen supplements are widely used for a variety of illness and health reasons. The use of collagen protein in our diet helps to repair different parts of the body, from hair down to the fingernails. What are the other benefits of collagen for our health?

Can Improve the Appearance of Aging Skin

One of the most important benefits of using a collagen supplement is that it can improve the appearance of aging skin. Collagen is a protein found in connective tissue, so it’s no surprise that this compound plays an important role in your skin’s health and appearance.

When you have more collagen, your skin will look younger and healthier. It may be harder for wrinkles to appear because of the increased elasticity in your skin. This means that you won’t have to worry about spending money on expensive creams or other products to keep your skin looking young.

Can Reduce Joint Stiffness or Pain

Collagen supplements can also help with other issues related to aging, such as joint pain and stiffness.

The reason behind this is because they help increase the amount of elasticity in joints by encouraging new collagen production. This makes it easier for joints to move smoothly without causing pain or discomfort.

Can Increase Hair Density and Nail Growth

While collagen helps to keep our skin smooth, soft and strong, it also helps to keep our hair thick and strong. Collagen supplements are made from natural ingredients that help to improve the quality of your hair and nails.

Can Improve Digestion by Regulating Stomach Acid

Collagen can help improve gut health by regulating stomach acid production. This will help to prevent digestive issues such as bloating and gas.

It can also aid in healing wounds faster because it promotes healing of damaged tissues due to its ability to bind cells together tightly while maintaining flexibility at the same time with its elastic properties within its structure itself, even though it’s made up mostly out of proteins.

Can Improve Bone Density (And Help With Osteoporosis)

Collagen is a protein that’s found in the skin, bones, tendons and ligaments. As we age and our body produces less collagen, our bones become less dense and more fragile. The result of this process is osteoporosis—the condition where bones become weak and brittle.

Osteoporosis can cause problems such as fractures, joint pain and deformity. It can also make it difficult for people to perform simple tasks like walking or bending over.

While there’s no cure for osteoporosis, taking collagen supplements can help you maintain your bone density and prevent future fractures.

Can Enhance Detoxification and Remove Toxins

When eaten, collagen supplements are digested into amino acids that are then absorbed into your blood stream through the intestines.

Once in your blood stream, these amino acids can be used as building blocks for new proteins such as enzymes and hormones that regulate bodily functions such as digestion, sleep cycles and immune system responses to external stimuli like infections or allergens.

5 Things To Look for When Buying Best Collagen for Gut Health

By looking for these 5 things you can have peace of mind and know that what you are buying is indeed the best collagen available, that will actually work and help your gut health.

#1 – High-quality Ingredients

You can find the best quality ingredients if you look at the ingredients list carefully and check the company’s website to see if they disclose any of their manufacturing processes.

Also, make sure that you’re buying from a reputable company and that they have a good reputation in the industry. You’ll also want to take into consideration your own dietary needs when considering which product is right for you.

#2 – Third-party Testing

When buying the best collagen for gut health, it’s important to look for third-party testing.

Third-party testing is when a company hires an outside lab to test their product. This way you can be sure that what’s on the label is actually in the bottle, and that you’re getting what you pay for.

A lot of companies will do this for themselves, but some will outsource the task to a lab that specializes in testing supplements. These labs have the equipment necessary to ensure that your product has what it claims to have—and they can help you figure out whether or not it’s working.

#3 – Form (Gelatin, Raw, or Collagen Peptides)

Collagen comes in several different forms, including gelatin, raw and collagen peptides. Each form has its own benefits and drawbacks. Gelatin is extracted from animal hides or bones and contains protein as well as collagen, which is good for bone health.

Raw collagen is made from grass-fed cows that have not been treated with antibiotics or hormones. It has many benefits, such as improving digestion and promoting healthy skin.

Finally, collagen peptides are made from processed protein found in animal bones or skin that has been broken down into smaller pieces called amino acids.

Collagen peptides can be beneficial for weight loss because of their ability to stimulate fat burning enzymes within the body while also increasing your metabolism by up to 15%.

#4 – Collagen Supplement Dosage

The recommended daily dose of collagen supplements varies from product to product, but it’s generally between 5 and 10 grams per day. If you’re taking a smaller dose than that, it may not be enough to help your gut health.

#5 – The Source of the Collagen

Collagen is a protein that can be extracted from various sources, such as bone, skin, and tendons. The type of collagen you choose will depend on what your body needs most.

For example, if you are looking for a supplement to help with a digestive issue, you may want to look for one that contains marine collagen hydrolysate or bovine gelatin hydrolysate because these are easier for your body to digest.

Does Collagen Help With Gut Issues?

YES. Collagen is a protein that contains amino acids, which are necessary for the formation of new cells. The intestines contain the most amount of collagen in the body, and it provides structural support to help maintain healthy intestinal walls.

Which Type of Collagen Is Good for Leaky Gut?

Type III collagen is abundant in your intestine, muscles, blood arteries, and the uterus. It’s most commonly combined with type I collagen to promote intestinal healing and increase skin elasticity and moisture.

You can also support your gut healing program by taking L-glutamine supplements such as Optima, which also help prevent leaky gut.

Does Collagen Reduce Gut Inflammation?

YES, collagen reduces gut inflammation.

Collagen is a protein that helps to thicken the gut wall and protect it from damage. This makes it more difficult for bacteria to penetrate the gut wall and cause inflammation.

How Much Collagen Should I Take for Leaky Gut?

The amount of collagen you should take for leaky gut depends on your individual needs. For example, if you have a very severe case of leaky gut, you may need to take the maximum dosage of collagen daily to see results. If you have a mild case of leaky gut, you may be able to take less than the recommended daily amount and still see benefits.

It’s also important to remember that collagen doesn’t directly treat or cure leaky gut; it helps support the lining of your digestive tract so that it can better heal itself.

Are There Any Negative Effects of Taking Collagen?

NO, but while there are no known negative effects of taking collagen, you should speak to your doctor before taking any new dietary supplements, especially if you have a pre-existing medical condition.


Choosing the best collagen for gut health should depend on your personal preference while keeping budget in mind. Try to choose a brand with a high concentration, especially if you intend to take it long-term.

If you are able to recognize certain flavors that you may not be fond of, this makes it easier to choose a time-released collagen supplement that is tasteless or at least not repulsive.

One last piece of advice would be to avoid any type of cheap or free trial supplements because of their poor quality and the chance that they are contaminated.

Gut health is essential to your overall health. So taking a comprehensive approach to supporting it should be high on your list of priorities each year.

And although you may be tempted to choose the cheapest product on the market and get a quick fix, why not take the time to consider even more long-term options.

By doing so, you stand to benefit all year long. After all, strengthening your gut health is a process that takes time.
