Collagen and the body
Collagen and cartilage
Cartilage is present in joints. It is composed of more than 70 % of collagen. It acts as a shock absorber and facilitates movement. A lack of collagen in the cartilage leads to the destruction of its cells and its degeneration. As degeneration progresses, the end of bones can rub against each other, causing pain and limiting movement of the affected joint.
Collagen and tendons
Tendons, fibrous tissues that link muscles to bones, are primarily made of collagen. These tendons support and stabilize joints. Their strength and structure is determined by the quality and health of their collagen.
Collagen and bones
Made mostly of collagen, bones are living tissues formed by bone cells. Without them, mineral deposits in bones would be impossible. A reduction in the production of collagen by these cells can cause bones to weaken. With time, there are less and less minerals and bones become porous, weak and can fracture more easily.
Collagen and ligaments
Ligament are made of fibrous tissues rich in collagen. These tissues link bones together and ensure good joint mobility. A deficiency of collagen weakens ligaments, facilitates incorrect movements and leads to injury and tissue damage.
Collagen and muscles
Muscles are made up of connective tissue primarily composed of collagen. During muscle contraction, collagen allows cell muscles to adapt to mechanical changes. A reduction in the production of collagen leads to weakened muscles, micro-lesions and a delay in healing. Collagen reduction also affects intramuscular nerve fibers leading to a decrease in tolerance to pain.
The production of collagen in the muscle helps to increase lean muscle mass. Physical fitness studies indicate that an increase in muscle mass typically helps the metabolism to use fats and sugars more efficiently, leading to a decrease in fat. In fact, many people will wear smaller clothes without noticing any difference on the scale.
Collagen and skin
To retain its youthful appearance , the skin must have the ability to constantly renew. The skin is made of three distinct zones: the epidermis, the dermis and the hypodermis. The dermis nourishes the skin and serves as support tissue. It is composed of cells that build the extracellular matrix made of collagen fibers. The collagen fibers in the dermis give skin resistance , tonicity and elasticity. With age, these fibers gradually thin out. This decrease in the skin causes wrinkles or fine lines, stretch marks, dryness, loss of tonicity, and lack of flexibility of the skin. As early as the age of thirty, we can see the eye contours starting to droop, causing the appearance of fine lines and small bags.
Collagen and eyes
The human eye is primarily composed of connective tissu. L’œil humain se compose principalement de tissu conjonctif. The sclera ( the tissue that makes up the white of the eye ) is composed of collagen and represents 80% of the eye. The cornea is composed primarily of collagen fibers.
