Collagen is the most important protein of the human body, which affects the level of hydration, skin elasticity and firmness. Lack of collagen in the skin not only causes wrinkled skin, the formation of bags under the eyes and double chin, poor hair, brittle nails and general deterioration of the skin all over body, but it also affects the functionality of the musculoskeletal system, because it is found in all tissues, in the skin, bones, tendons, ligaments, cartilage, teeth and interdental spaces. Collagen accounts for 30% of all proteins in the body and up to 70% of proteins in the skin. Collagen forms by itself, but not forever. Its self-creation is beginning to decrease from the age of 25 and after the age of 45 collagen does not form almost at all in the body. It should therefore be supplemented.
