While shopping for a collagen supplement, you must have noticed “contains collagen I and III” written in all caps on the label. So, you might be wondering why exactly collagen supplements contain collagen 1 and 3? And what are the benefits of each collagen type? 

A quick summary of the differences between the three main types of collagen:   

Collagen Type 1: Prevent fine lines and wrinkles, skin thinning, and improve hydration with collagen type 1. Type 1 collagen makes up to 90% of your skin, hair, and nails—having more of it helps you grow thicker hair, stronger nails, and maintain glowing skin. 

Collagen Type 2: Less common collagen type compared to type 1, mainly found in cartilage tissue. Gives your cartilage strength and elasticity by reducing joint inflammation, stiffness, and promoting lubrication. 

Collagen Type 3: A key structural component for bone, cartilage, dentine, tendons, skin and other connective tissues. Type 1 and type 3 collagen offer similar benefits for the skin, hair, and nails, which is why you’ll find them side-by-side in collagen products.

In this article, we’ll discuss:

  • The differences between animal and marine collagen
  • Benefits of collagen type 1 
  • Benefits of collagen type 2
  • Benefits of Collagen type 3
  • Sources of collagen 
  • The natural process of collagen production in the body 

Animal vs. Marine Collagen

Animal Collagen 

Collagen comes from different animal sources. 

Bovine (beef) collagen is type 1 and 3 collagen and comes from the hide, bones, cartilage, tendons, and placenta of cows and other bovine. This type of collagen is one of the most popular and offers all of the benefits of collagen. 

Pig collagen is mostly used by individuals who are sensitive or allergic to bovine collagen. 

Chicken collagen contains the widest variety of collagen types but is not as common as bovine collagen. With chicken collagen, there is a risk of aviary disease contamination. 

When purchasing animal collagen, it’s essential to look for collagen extracted from animals that have not been treated with artificial growth hormones or antibiotics. 

Marine Collagen

Marine collagen is exclusively type 1 collagen. This type of collagen comes from fish, starfish, jellyfish, octopus, squid, and is better absorbed by the body. 

Marine collagen works the same way as animal collagen in the human body, but it absorbs better. It is believed that marine collagen comes in small molecules that penetrate the skin and stimulate collagen synthesis in a more efficient way than animal collagen. 

Benefits of Collagen Type 1 2, and 3

Type 1 Collagen

Type 1 collagen is a major component of your skin, eyes, bones, tendons, and teeth. Collagen type 1 keeps you skin smooth by improving elasticity and hydration. 

After the age of 25, the body starts to produce less collagen, leading to dry skin and formation of wrinkles. Collagen supplements can slow down the aging process by promoting the production of collagen in the body. 

Benefits of collagen type 1:

  • Prevents fine lines and wrinkles
  • Helps improve skin elasticity
  • Helps with skin hydration
  • Helps you grow thicker hair and stronger nails

One study found that women aged 35-55 who took 2.5-5 grams of collagen supplement for eight weeks experienced less skin dryness and significantly higher skin elasticity (especially in elderly women) compared to those who didn’t take the supplements. [1]

Type 2 Collagen 

Experiencing joint pain? This type of pain is a result of cartilage degradation as we age and is also common in active people as well as overweight people. To minimize joint pain and reduce inflammation, try type 2 collagen. Type 2 collagen helps reduce swelling, stiffness, and joint pain. 

Type 2 collagen is mainly found in cartilage tissue—the connective tissue that acts as a shock absorber and a lubricator between bones. Collagen 2 is the substance that gives cartilage its strength and elasticity. 

Benefits of Type 2 Collagen:

  • Supports and improves joint health
  • Essential for cartilage strength
  • Support spinal disks health 
  • Great for eye health 

Type 3 Collagen  

Collagen type 3 offers similar benefits to collagen type 1 and is the second most abundant type in the body. Collagen type 3 is present in the intestines, muscles, skin, cartilage, and blood vessels. 

Benefits of Type 3 Collagen:

  • Important for gut health 
  • Improves skin elasticity
  • Plays a vital role in the formation of arterial walls
  • Improves skin hydration

Sources of Collagen Types 1, 2, and 3

Eating collagen-rich foods and foods that boost the production of collagen may help create the amino acids your skin, hair, and nails need. The biggest sources of collagen are:

  • Bone broth  
  • Chicken 
  • Fish and shellfish 
  • Citrus fruits
  • Egg whites
  • Tropical fruits
  • Berries
  • Tomatoes 
  • Bell peppers
  • Garlic
  • Leafy greens
  • Beans 

Sometimes, an all-natural diet requires a lot of effort, and it’s hard to stick to it for a long time. Luckily, there is an easier way to maintain a healthy and youthful look of your skin, hair, and nails. 

For regular, daily collagen intake that supports the production of collagen in your body, try the Hair Bears Collagen Gummies. HairBears are gelatin-free, non-GMO, 100% type 1 and 3 hydrolyzed collagen that helps your body sustain healthy collagen levels. In addition to maintaining firmness and tone of the skin, this collagen supplement is great for your muscles, bones, and eyes. 

Why Hair Bear Collagen Gummies Use Collagen Types 1 and 3

The reason why Hair Bear Collagen Gummies use a combination of collagen 1 and 3 is that these two types of collagen offer similar benefits to your body. Type 1 and 3 collagen are the most important types of collagen for quality skin, hair, nails, as well as bones, muscles, and joints. 

Both collagen type 1 and type 3 contain glutamate, an amino acid vital for gut health. Also, collagen 1 and 3 become less effective if combined with collagen II, so it’s advised to take collagen 2 separately. 

How Your Body Makes New Collagen

How does your body make new collagen? There are more than 14 different types of collagen, and they have to be produced by your body. 

So, when taking collagen supplements, the collagen is already broken down or hydrolyzed, so your body can absorb it more efficiently. The body goes through three main phases to produce collagen:

  1. Creating Procollagen

Before collagen is created, the body forms its precursor: procollagen. Procollagen is formed in the cell by three different chains of amino acids, including glycine, proline, and hydroxyproline. Glycine is the principal component of collagen and is the most abundant amino acid in collagen with over 35%. This component is very significant for muscle growth, digestion, joint support, cognitive function, and more. 

  1. Creating Tropocollagen

After leaving the cell, procollagen is turned into tropocollagen, aka the final collagen strand. 

  1. Formation of Collagen

Collagen strands as tropocollagen bond together to form the collagen protein. 

Now you know the differences and benefits of the three main collagen types. Collagen supplements can greatly benefit your skin, hair, and nails, and is good for the bones, muscles, and joint health. 


What is the difference between types 1, 2, and 3 collagen?

Collagen 1 is the most abundant type of collagen in the body and is important for skin elasticity and hydration, strong bones, skin, and nails. Collagen type 3 offers similar benefits to collagen type 1, while collagen type 2 promotes joint health.

What’s better marine or animal collagen?

It all comes down to which one you prefer. Both marine and animal collagen work the same in the body. Marine collagen comes from fish and sea products, while animal is present as bovine, pig, and chicken. Marine collagen is better absorbed than animal because it comes in smaller molecules.

Is collagen safe?

Yes, collagen is considered generally safe. There are no reported severe risks of using collagen.

What are the side effects of collagen?

Allergies may be the most common reason for people to avoid collagen supplements. These products are made with ingredients such as fish and eggs, which are common allergens. Aside from occasional heartburn, feeling of fullness, and a bad taste in the mouth, collagen doesn’t produce any side-effects.
