Collagen is the most abundantTrusted Source protein in your body. It’s the main component of connective tissues that make up several body parts, including tendons, ligaments, skin, and muscles. It has many important functions, including providing your skin with structure and strengthening your bones.
You can get collagen from foods like pork skin and bone broth, but collagen supplements have also become popular. Most are hydrolyzed, which means the collagen has been broken down to make it easier to absorb.
These supplements come primarily in powder form but are also available in capsules. The types of collagen found in supplements vary — some contain one or two types, while others contain up to five.
