What is collagen?

Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body. In most collagens, the molecules are packed together to form long, thin fibrils. These act as supporting structures and anchor cells to each other. They give the skin strength and elasticity.

Collagen is the most abundant protein in the human body, found in the bones, muscles, skin, and tendons. It is the substance that holds the body together. Collagen forms a scaffold to provide strength and structure.

Endogenous collagen is natural collagen, synthesized by the body. Exogenous collagen is synthetic. It comes from an outside source, such as supplements.

Endogenous collagen has a number of important functions. Breakdown and depletion is linked to a number of health problems.

Exogenous collagen is used for medical and cosmetic purposes, including the repair of body tissues.

There are at least 16 different types of collagen, but 80 to 90 percent of them belong to types 1, 2, and 3. These different types have different structures and functions.

The collagens in the human body are strong and flexible.

Type 1 collagen fibrils are particularly capable of being stretched. Gram-for-gram, they are stronger than steel.

Fast Facts on Collagen

Here are some key points about collagen.

Collagen occurs throughout the body, but especially in the skin, bones, and connective tissues.

Some types of collagen fibrils, gram-for-gram, are stronger than steel.

Collagen production declines with age and exposure to factors such as smoking and UV light.

Collagen can be used in collagen dressings, to attract new skin cells to wound sites.

Cosmetic lotions that claim to increase collagen levels are unlikely to do so, as collagen molecules are too large to be absorbed through the skin.
