Gram for gram type 1 collagen fibrils are stronger then steel. Collagen type 1, 2 and 3 are the most common collagen in our bodies known as fibrous collagen because they form long strands. Collagen type 1 is abundant in skin, tendon, ligaments, teeth and bones and between organs. The collagen are formed by polypeptides made mostly of glycine, proline and hydroxyproline. However, as we age we need to find ways to boost collagen naturally.
