Essential for the functioning of several tissues and naturally present in the body, collagen remains little known. Learn more about the key role of this protein, which contributes, among other things, to skin elasticity, and discover all its benefits.
What is Collagen?
Collagen is the main component of connective tissues, which include skin, tendons, bones, cartilage and ligaments. This fibrous protein, composed of amino acids, is called “structural” because it serves as a physical and mechanical support to cells and tissues.
Several Types of Collagen
There are 28 types of collagen, with the first 3 making up most of the collagen in the body. Each has a distinct function and role.
Type I Collagen
This is the one most often found in skin, tendons and bones (among other things).
- Benefits: It preserves skin elasticity and helps in healing and regeneration of epidermal tissues. It also contributes to bone strength.
- Sources in Food: fish, egg whites, bone broth, chicken skin
Type II Collagen
It helps in the construction of cartilage that covers bones and allows joints to move smoothly.
- Benefits: It stimulates cartilage production, reduces inflammation, and allows greater flexibility and mobility. It relieves joint pain, including, among other types, those associated with osteoarthritis.
- Sources in Food: chicken cartilage, supplements
Type III Collagen
It is found in the skin, internal organs including the liver and lungs, blood vessels and heart tissues.
- Benefits: Together with type I collagen, it helps maintain the flexibility and structure of tissues and makes them more resistant.
- Sources in Food: bone broth, beef collagen, animal skin
What Are the Effects of Collagen Loss with Age?
For biological reasons, collagen production slows down with age, which contributes to the appearance of visible signs of skin aging and weakens the joints. This gradual reduction concerns:
- The Skin
Thanks to collagen, it remains firm, supple and hydrated. Its decrease leads to a loss of elasticity, a refinement of the skin that dries out and becomes duller.
- Bones
Collagen boosts bone density, helping to prevent osteoporosis. A lack of collagen weakens bones and increases the risk of fractures.
- Hair and Nails
Helped by collagen, hair is stronger and thicker, and nails less brittle. A decrease refines the hair and slows down its growth while the nails become softer and brittle.
- Joints
Less collagen wears down the cartilage, causing joint pain and stiffness. Mobility is reduced and the risk of developing osteoarthritis increases.
- Muscles
Collagen helps maintain muscle mass. A drop in production affects muscle recovery and causes them to lose flexibility, which increases the risk of injury.
What Can Be Done to Counteract the Drop in Collagen?
Several hydrolyzed collagen powder products based on fish, beef or chicken bone broth are available in Rachelle Béry spaces. Some are gluten-free, others flavoured or enriched with vitamins. Simply add these extras to your favourite hot beverages, smoothies, juices, soups, yogurts, etc. to take advantage of the potential effects of collagen on the skin, joints, hair and nails.
