Collagen types 1, 2 and 3: These are the differences

Collagen types: everything you need to know about types 1, 2, and 3

Collagen is a central structural protein found in skin, bones, and connective tissue. But did you know that there are different collagen types? The best-known are Type 1, Type 2, and Type 3 . But what exactly sets them apart, and how do they work in your body? In this guide, you’ll learn everything about the unique properties of the different collagen types, their specific benefits, and how to choose products that fit your glow.

What are collagen types and which ones are there?

Collagen is not just any protein — it is the “building material” that makes up a large part of our skin, bones, and connective tissue. But collagen is not always the same: there are different types that vary in structure, properties, and where they are used. Some are extremely strong and provide structure, while others are elastic and enable flexibility. The three best-known — Type 1, Type 2, and Type 3 — fulfill very different roles in the body and often work together. Understanding their differences helps you better understand how our body is built and how fascinating this network of structural proteins really is.

Collagen Type 1: The structural expert

• Found in: skin, bones, tendons, ligaments, teeth
• Share in the body: around 90% of all collagen
• Property: extremely tensile, provides stability and structure

Type 1 is the superstar among collagen types. It is especially densely organized, almost like a tightly woven fabric. This structure makes it ideal for withstanding tensile forces. Type 1 plays its role as the most common collagen type primarily in skin and bones.

Collagen Type 2: The joint supporter

• Found in: cartilage tissue, intervertebral discs, eyes (vitreous body)
• Property: pressure-resistant, elastic

Type 2 specializes in handling stress from all directions. It is found mainly in cartilage, which acts as a cushion between the joints. That is what allows us to move smoothly — whether in yoga, climbing stairs, or dancing.

Collagen Type 3: The flexibility partner

• Found in: skin, blood vessels, internal organs, lungs
• Property: elastic, finely structured

Type 3 often appears together with Type 1 — they are something of a dream team for our connective tissue. While Type 1 provides stability, Type 3 brings flexibility into play. This is particularly important for tissues that frequently need to stretch and contract again, such as blood vessels or lungs.

How do the collagen types differ?

Each collagen type has its own superpowers, but it becomes especially interesting when you compare them side by side. A direct comparison shows how different their tasks in the body are and why all three play a special role. While Type 1 is more of the architect of stability, Type 2 acts as a flexible shock absorber and Type 3 brings smooth elasticity into the picture.

Each collagen type has its own area of expertise, and together they form the foundation for stability, elasticity, and mobility in our body. When you understand which type is active where, you can pay more targeted attention to giving your body the right building blocks — through a balanced diet and a healthy lifestyle or through our Glow25 collagen products. ✨

FAQ: Frequently asked questions about collagen types

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

The collagen types differ in their function and in the areas of the body where they occur. Type 1 is the most common collagen type and is found mainly in skin, bones, and tendons. Type 2 is found primarily in the cartilage tissue of the joints. Type 3 is often found alongside Type 1 in the skin and blood vessels.

Can I buy a collagen product that contains all three types?

Yes, there are products that contain a mixture of collagen types 1, 2, and 3. If you are looking for collagen powder or collagen capsules that include all three types, you can choose a product that covers the full range. There are also variants that additionally contain, for example, vitamin C or high-dose collagen with up to 3000 mg.

What are collagen peptides and how do they differ from collagen types 1, 2, and 3?

Collagen peptides are broken down into smaller units and are therefore easier to digest. They come from the same collagen types — 1, 2, and 3 — and offer high bioavailability. The main difference between collagen peptides and intact collagen fibers lies in easier digestion and faster absorption in the body. They are available in various food supplements and are an easy way to take collagen.
