* Collagen is a major component of your skin.
It plays a role in strengthening skin, as well as in elasticity and hydration. As you age, your body produces less collagen, leading to dry skin and the formation of wrinkles.

* These supplements may work by stimulating your body to produce collagen on its own. Additionally, collagen supplements may promote the production of other proteins that help structure your skin, including elastin and fibrillin.

* Collagen helps maintain the integrity of your cartilage, the rubber-like tissue that protects your joints
As the amount of collagen in your body decreases with age, your risk of degenerative joint disorders such as osteoarthritis increases.

* Studies suggest that collagen supplements help boost muscle mass in people with sarcopenia, the loss of muscle mass that happens with age.

* Collagen provides structure to your arteries, the blood vessels that carry blood from your heart to the rest of your body. Without enough collagen, arteries may become less flexible and elastic.

* Collagen supplements have several benefits related to skin, joint, bone, muscle, and heart health. There’s scant evidence to support collagen’s purported effects on weight loss or gut or brain health.
