Collagen

What is Collagen?

Collagen, the most abundant protein found in our bodies, is hard, insoluble and fibrous. It is considered the glue that holds our body together; in fact, the word comes from the Greek “kolla” meaning “glue”. It is found in our muscles, bones, tendons, and skin; it is what gives our skin strength and elasticity.
