Collagen: hydration, strength, elasticity of tissues

Understanding the different types of collagen and their functions: cohesion, tissue structure, hydration



Collagen: a protein unlike any other

Collagen, very common in humans and in all living organisms, is a protein with a fibrous consistency (not very elastic) constituting the majority of the connective framework (connective tissue).

The different collagens:

Collagens of types I to V represent 99% of all collagen found in the body. They are present in the body as follows:
Type I: Bones, tendons, ligaments and skin;
Type II: Cartilages and structure of the eyes;
Type III: Liver, lungs and arteries;
Type IV: Kidneys and several internal organs;
Type V: Cell surfaces, hair and placenta.

Role of collagen:

Collagen is produced by specialised cells called fibroblasts and is assembled in connective tissues.
The biological role of collagen has a dual function.
On the one hand, together with elastin and glycoproteins, it is responsible for the cohesion of tissues and organs.
On the other hand, collagen provides properties of hydration, strength, elasticity and suppleness to these same tissues and organs.
Connective tissues themselves form a framework rich in collagen found in practically every part of our body. They mainly serve as support, filling, attachment, insulation, protection or even transport in the case of the blood system.
Without this matrix of connective tissues rich in collagen which acts like "a kind of glue that holds our body together", we would be nothing but a puddle of water.

Several factors can harm and even reduce the production of collagen by the body, including smoking, heavy and regular consumption of alcoholic beverages, coffee, intense stress and strenuous physical training. Moreover, infections, pollution, harsh climatic conditions and the taking of several medications also impoverish the body.

We, who wish to look young and feel young for a long time, should take an interest in collagen synthesis.
Therefore, we should consider any dietary supplement that can increase the reconstruction and healing process of the body.

The body produces its own collagen every day but since production decreases with age, the available supply of collagen quickly becomes insufficient and various parts of the body gradually deteriorate. The first obvious signs are the appearance of wrinkles and the onset of pain. Common wrinkles and pain represent only part of the resulting effects.

As health begins inside the body, the secret of a youthful and healthy appearance is to act at the source of degeneration before it sets in and to
