Collagen makes up a lot of the material found in bones, teeth, ligaments and tendons. As we age, collagen levels become depleted and this leads to a more fragile body (and wrinkles). Some people have a higher collagen content than others.

Collagen has many uses outside of the body. One of those uses is in gelatin. Gelatin is found in many of the foods we eat, including jello. It is also used in some glues. The oldest glue dates back 8000 years and collagen was used to make it.

It also has medical uses as well. It is used in burn victims as a skin substitute and it is used in certain cosmetic surgery procedures.

Collagen is a protein of connective tissue from human and animal body. Collagen has a flat character and it's obscure in the skin. When it occurs in tendons, it is in the form of  hard and heavy fibrous strings. Collagen supports the body in many ways, from supporting the blood vessels to the support of the skin.

The origin of the word is from greek, and translated means "glue producer". This name has appeared because of boiled animal skin, from where collagen is isolated to produce the adhesive.

The body tends to produce less quality colagen or weaker as it gets older. Skin is actually collagen in 70%. When a small amount of collagen or of a inadequate quality is produced, the skin loses its elasticity.The age, and therefore the lack of collagen, is reducing the power to stretch of the tendons. The ability to move freely and comfortably is reduced because of that.

Sun's ultraviolet rays are one of the main enemies of collagen. Also, the residual sugar from digestion has an adverse effect on collagen from the skin.
