Collagen is a naturally occurring fibrous protein that provides structure to the body's tissues. The body's supply of collagen depletes as people get older, so increasing collagen intake is beneficial for people who are starting to see and feel the first signs of aging.

Because collagen is found in the body's connective tissues, it is integral to joint health, skin and hair health, and more. Collagen can help improve the appearance of the skin, as it promotes healthy reparation of skin cells. This may leave skin feeling firmer and looking younger.

Collagen is often uses by people suffering from joint pain. As levels of collagen decrease, joints begin to swell and stiffen. Increasing collagen intake can provide relief from arthritis, and may help to reduce the risk of joint deterioration.

This beneficial protein may also boost metabolism, relieve digestive issues, and strengthen teeth and nails.
