Collagen

The protein has a big job in the body. “Collagen gives body tissues structure, toughness, rigidity, and texture. In the skin, it’s akin to a layer of leather. And when it intermingles with elastic fibers, it gives skin strength and resilience,” says Yag-Howard.

When collagen begins to degrade in skin and levels drop in the body, you may notice wrinkles, stiffer tendons and ligaments, weaker muscles, joint pain, and even GI problems, according to the Cleveland Clinic. (3) It’s clear that collagen is vital for the health of every system in your body.
Better skin health
Some people who take collagen supplements are looking to improve the look and overall health of their skin.

Many believe that collagen supplements can help reduce the effects of aging, such as by adding moisture to the skin, reducing wrinkles, and improving elasticity.
Improved joint health
As a person ages, their joints start to break down. In particular, the spongy cartilage of the joints starts to wear away.

There is some evidence to suggest that collagen supplements can help with restoring or preventing the deterioration of the cartilage in the joints.
Increased muscle mass
There is some evidence to suggest that using collagen supplements may help increase muscle mass.
Prevents bone loss
Collagen makes up a significant amount of bone structure and helps keep the bones strong.

As a person ages and collagen production slows, bones can become weaker as the person loses the collagen necessary to keep the bones strong and supported.

This can lead to the development of conditions such as osteoporosis.
Supports heart health
Taking collagen supplements may also help support a healthy cardiovascular system.
Some other potential things that collagen may help with include:

maintaining a healthy gut
maintaining a healthy weight
reducing anxiety
improving mood
promoting healthy nail and hair growth
