Collagen is a protein that is responsible for healthy joints and skin elasticity. It is found in bones, muscles, and blood, and comprises three-quarters of your skin and a third of the protein in your body. As you age, your existing collagen breaks down, and it gets harder for your body to produce more. As a result, many people turn to collagen powder or other types of collagen supplements, such as capsules, gummies, and liquids.

Collagen supplements are usually made from the tissues of cows, pigs, chickens, or fish, and contain a digestible form of collagen called collagen peptides or hydrolyzed collagen. Vegan collagen powders made of bacteria and yeast are also available, but scientists don’t know whether they have the same possible benefits as collagen from animal sources. Collagen supplements are associated with several health benefits and very few known risks.
