What is Collagen?

Collagen is a type of protein naturally found in our body, making up approximately 30% of our total protein. This structural protein is a fundamental component of the skin, bones, joints, tendons, cartilage, and blood vessels.

If we ask what collagen means, it is derived from the Latin word "kolla" (glue), and it indeed acts as the glue that holds our body's tissues together.

Collagen is made up of long chains of amino acids. Specifically, glycine, proline, and hydroxyproline amino acids are abundant in collagen. This unique combination of amino acids is what distinguishes collagen from other proteins.

Collagen is very important for skin health.

What is Collagen Good For?

The benefits of collagen are quite broad:

Skin Health

Collagen provides the skin's elasticity, moisture, and firmness. Decreased collagen production with age leads to the appearance of aging signs such as wrinkles and skin sagging. Regular collagen supplementation can help improve skin appearance.

Joint Health

Collagen is the main component of cartilage, ensuring healthy joints. If we ask what especially type 2 collagen is good for, this type found in joint cartilage helps reduce joint pain and increase mobility.

Bone Health

Collagen constitutes 90% of the organic part of bones. Collagen provides flexibility to bones and resistance against fractures.

Muscle Development

Collagen acts as a building block of muscle tissue and helps preserve muscle mass.

Types of Collagen

There are 28 different types of collagen in our body, but these four types make up 90% of them:

  • Type 1 Collagen: Found in connective tissues, skin, and bone

  • Type 2 Collagen: Found in cartilage tissue

  • Type 3 Collagen: Supports muscles, arteries, and organs
