Collagen is an important substance that maintains normal body functions. It is also essential in preventing aging and diseases. There is a great knowledge behind collagen and it is always good for you to know the basic knowledge of it!

Collagen is actually a kind of protein. Majority of proteins that required by human bodies are produced by our bodies. Only a minority has to be absorbed from daily diet. There is not only one type of collagen produced by our bodies but many. Collagen is also one of the big groups of proteins in our bodies. The most abundant collagen found in human bodies is named as Type I Collagen. You may find plenty amount of Type I Collagen in scar tissue, tendons and the organic part of bone.

Collagen is mostly found in tissues that are without water. For example, 73 percent of muscle; 86 percent of ligament; 53 percent of cartilage and 26 percent of bone are composed of collagen. Besides, collagen is the main component of dermis of human skin.

The importance of collagen is not a hypothesis; it has been proved by scientists. Collagen acts as the foundation of bones, skins, cell growth and internal organs. It is able to harden our nails and increase density of bones. It also promotes health of skin and hair as it retains moisture and elasticity in these cells.

During the 24 hours of a day, there are certain best times for collagen intake. Collagen absorption is higher for empty stomach. Therefore, it is better to have collagen supplements before meals. Besides, you are also advised to take collagen supplements before going to bed as the whole body is under regeneration during sleep.

Though collagen is essential to human body, it is not always sufficiently produced. In fact, collagen production in human bodies decreases when our ages increase. The production speed decreases significantly from the age of 25. Such decrease is continuous and unavoidable. When you are 60 years old, only 30 percent of collagen is left in your body.

There are three main causes of the decrease in collagen including UVA, metabolic rate and saccharification of collagen. When our skin is exposed to the UVA in the sunlight, collagen is damaged by such radiation. When we grow older and older, our metabolic rate slows down. When the metabolic rate slows down, the production of enzyme to decompose aged collagen slows down as well. Hence, the generation of new collagen is hindered. Finally, once old collagen integrates with saccharin, they are unable to be separated. This process prohibits the production of new collagen.
