There are different types of collagen and knowing them all is essential to learn more about the proteins necessary for your body and organism’s needs. Well known for the benefits it provides for the skin, collagen goes beyond that, and can also act on different parts of the body, such as bones.

In fact, for those who don’t know, collagen is a protein of animal origin that represents between 25 and 30% of the proteins present in connective tissues, such as cartilage, bones, tendons, teeth, veins, skin and also in muscles and horny layer of the eyes.
