Collagen is the main structural protein in our body. You can think of it as a framework on a house, it provides the structural support that holds our body together. It is found in bones, muscle, skin, hair, ligaments and tendons. It comprises 30% of all the protein in our body. This protein is crucial for the maintenance of skin integrity, muscle mass, and healthy bones. Starting in our 20s we lose 1% of our collagen per year, and then as we get to our 50s, we can lose upto 30% per year
