Collagen is the most abundant protein in the human body, accounting for over 30% of the total weight of all proteins. As a key structural protein, it provides elasticity, stability and resilience to cartilage, tendons, ligaments, connective tissue, muscles, blood vessels, skin, bones and teeth. During endogenous collagen synthesis, amino acids are linked together to form a polypeptide chain with the help of several essential vitamins, minerals and trace elements.
Depending on the type of tissue, collagen exists in different types that ideally complement each other in their function:
Type I collagen is the most common type of collagen. It is mainly found in the skin, tendons, ligaments, bones and teeth, giving these structures high tensile strength. Type I collagen is essential for firm skin, resilient tendons and strong bones.
Type III collagen is mainly found in the skin, blood vessels and internal organs. It provides flexibility and suppleness and supports vascular health and the elasticity of connective tissue. Types I & III collagen work closely together, forming a stable yet elastic tissue framework.
Hyaluronic Acid
Hyaluronic acid, also called hyaluronan, is a long-chain polysaccharide with a high water-binding capacity and high structure viscosity (plasticity), which maintains the elasticity of the skin and connective tissues. At the same time, it is a significant component of the joint fluid, the tear film and the vitreous body of the eye.
According to the European Food Safety Authority (EFSA):
- Biotin contributes to the maintenance of normal hair and skin.
- Vitamin C contributes to normal collagen formation for the normal function of skin, cartilage, bones, gums and teeth, and to the protection of cells from oxidative stress.
- Zinc contributes to the maintenance of normal skin, hair, bones and nails, normal protein synthesis and the protection of cells from oxidative stress.
