The Benefits of Collagen

1. Can ease joint pain

As cartilage deteriorates with age, you can start to feel stiff, achy joints. It is possible by increasing your collagen intake, you could reduce joint pain and the symptoms of arthritis.

In a 2009 study, participants took a type II collagen supplement made from for three months. Results showed that osteoarthritis symptoms decreased by 40% and the severity of symptoms dropped by 33%.

2. May reverse skin ageing

Collagen has the ability to promote glowing, vibrant skin. This essential protein delivers elasticity to the skin, helping it to appear more youthful and healthy.

But as we mature collagen production declines, meaning that fine lines, loose skin, and dryness can occur. A study published in 2014 randomly chose 46 of 69 women, ages 35 - 55 years old to take a collagen protein supplement. The rest of the group were given a placebo. The women who consumed the collagen showed an improvement in skin elasticity within four weeks.

3. Helps build muscle and burn fat

Collagen can have a significant impact when it comes to building muscle mass. Collagen contains glycine, an amino acid involved in the synthesis of creatine. This gives muscles with the fuel needed for strength throughout your workout.

A study in 2015 looked at collagen supplements in 53 older males with sarcopenia, a condition where muscle mass declines to ageing. After 12 weeks, those who took supplements along with resistance training saw an increase in fat loss and muscle strength compared to the placebo group.

4. May reduce cellulite

Collagen may also help improve the appearance of cellulite. 
Cellulite occurs when the layer of fat under the skin pushes up against the connective tissue, creating a dimpled or lumpy appearance on the skin.

A study was sponsored in 2015 by manufacturers to see what type I collagen does for cellulite. They randomly assigned 105 women, ages 24 to 50, to take collagen peptides for six months. Those who did showed a significant improvement in skin texture and lumpiness.

5. May improve digestive health

Collagen is also in the gut’s connective tissue and could help support and strengthen the protective lining of your digestive tract. 

A study from 2003 looked at 170 individuals with inflammatory bowel disease and showed that they were more likely to have lower levels of serum collagen.

Increasing your intake of collagen could help build up the tissues that line your gastrointestinal tract and promote better gut health.
