Collagen is the most abundant protein found in the body. These proteins form a mesh of fibers that help provide support and flexibility to the body’s tissues and form key components that lead to healthy muscle, skin, bones and tendons.

What does collagen do?

Collagen's main role is to provide the foundation for body parts, keeping them strong and supple. Each type of collagen has different properties and different functions.

Types of Collagen:

• Type I: Most abundant in collagen; composed of long, tightly packed fibers found in skin, ligaments, teeth, bones, and tendons.

• Type II: Shorter fibers found in cartilage, which form the tough, flexible tissue in body parts such as joints, ears, and nose.

• Type III: Found in body parts such as blood vessels, intestines, and skin; aids in blood clotting and wound healing.

Like an intertwined rope, each collagen fiber is made up of millions of proteins called peptides. All types of collagen help body tissues maintain their shape, elasticity and strength.

What is collagen for?

Collagen, which is naturally produced in the body, has a variety of functions, including supporting vision, hair growth and recovery after injury. It is believed that the broken down form of collagen in collagen supplements is easily transformed, broken down and absorbed into the body. This may make it useful for various medical and cosmetic purposes.

Manufacturers source collagen from cattle, chicken, and fish for use in supplements and medical products. Scientists are also investigating synthetic forms of collagen.

Medical

Collagen supplements are used in reconstructive, cosmetic and oral surgery. They have the potential to help wounds and burns heal and promote the growth of new tissue. Some people may use collagen supplements to reduce osteoarthritis symptoms.

Cosmetic

The natural properties of collagen make it attractive for cosmetic applications. Because it helps retain moisture, manufacturers add it to some skin creams and hair care products. In aesthetic medicine, injectable collagen fillers improve the quality and density of the skin.

Benefit

Research on the benefits of collagen supplements has mixed results. Several studies have found that this supplement can help increase muscle mass and strength, reduce arthritis pain, and reduce the appearance of wrinkles.
