Collagen is the most abundant protein in your body. It accounts for about 30% of its total protein. Collagen is the primary building block of your body’s skin, muscles, bones, tendons and ligaments and other connective tissues. It’s also found in your organs, blood vessels and intestinal lining.
Proteins are made from amino acids. The main amino acids that make collagen are proline, glycine and hydroxyproline. These amino acids group together to form protein fibrils in a triple helix structure. Your body also needs the proper amount of vitamin C, zinc, copper and manganese to make the triple helix.
