Collagen is a fibrous protein that functions as a building block for skin, tendons, joints, other connective tissues and bones. Collagen also keeps skin, bones, teeth and blood vessels healthy. Taking collagen supplements helps replenish and replace natural collagen, which decreases with age.
Reduction of Skin Wrinkles
According to the American Academy of Dermatology (AAD), skin wrinkle reduction is one of the possible benefits of taking collagen supplements. As people age, their skin’s natural elasticity lessens because of the decrease in collagen production. When the skin loses its elasticity, wrinkles and fine lines start to appear and skin will seem less firm and look loose.
The AAD notes that collagen supplements is one of several things you can do to improve your skin's elasticity and ability to recover from wounds. Wrinkle reduction and skin repair can also be achieved by using moisturizers, eating a balanced diet, getting enough sleep and by stopping smoking.
Reduction of Joint Pain and Stiffness
Relief from joint pain and stiffness is among the many benefits of taking collagen supplements, as described by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) . Collagen is responsible for keeping cartilage and joints intact and mobile by maintaining the fibrous and elastic structure of bones and joints. This elasticity enables people to move freely without pain or discomfort. Taking collagen supplements enables the joints to flex and extend properly. It also allows joints to absorb the shock associated with such everyday movements as walking and doing other activities.
Faster Wound Healing
According to the NIAMS, one of the benefits of taking collagen supplements is faster wound healing. Skin repair and wound healing after an injury usually happens on its own, but collagen supplements may speed up the process by stimulating tissue formation and wound contraction.
