What is collagen?
Collagen is the main protein of connective tissues, bones, tendons and skin that makes up about 40% of your the total body mass. It is also the main component of skin, cartilage, ligaments and tendons, and the main protein component of bone and teeth due to its tough and inextensible (with great tensile strength) properties. Along with soft keratin, it is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.
