Benefits of Collagen

Skin Health

Collagen is good for your skin. It can make your skin look younger. It reduces wrinkles and dryness. A study in 2014 found that women who took collagen had better skin elasticity after 8 weeks.

Collagen helps your skin stay firm and smooth. As you age, your body makes less collagen. This leads to wrinkles and sagging skin. Taking collagen supplements can help keep your skin looking youthful.

Joint Health

Collagen is also good for your joints. It helps reduce joint pain. A study in 2009 showed that athletes who took collagen had less joint pain.

Collagen helps maintain the cartilage in your joints. This keeps your joints flexible and reduces pain. If you have joint pain from exercise or aging, collagen supplements can help.

Bone Health

Collagen can improve bone health. It helps your bones stay strong. A study in 2018 found that women who took collagen had higher bone density.

Your bones are made mostly of collagen. As you age, your bones lose collagen and become weaker. Taking collagen can help keep your bones strong and reduce the risk of fractures.

Muscle Mass

Collagen can increase muscle mass. It helps build muscle after exercise. A study in 2015 showed that men who took collagen and exercised had more muscle mass than those who only exercised.

Collagen provides the building blocks for muscle growth. If you are trying to build muscle, collagen supplements can help.
