Collagen is one of the most abundant proteins in our body and it has important roles. We can find collagen in muscles, bones, skin, blood vessels, digestive system, and tendons. It gives our skin strength and elasticity. If we think about our joints and tendons, saying the simplest way, it’s the “glue” that helps hold the body together. What is collagen and where you can find it? Read more about it below.

What is collagen?

The name collagen comes from the Greek κόλλα (kólla), meaning "glue", and suffix -γέν, -gen, denoting "producing".[6][7] This refers to the compound's early use in the process of boiling the skin and tendons of horses and other animals to obtain glue.

Collagen is the main structural protein in the extracellular space in the various connective tissues in animal bodies. As the main component of connective tissue, it is the most abundant protein in mammals, making up from 25% to 35% of the whole-body protein content. Collagen consists of amino acids wound together to form triple-helices to form of elongated fibrils. It is mostly found in fibrous tissues such as tendons, ligaments, and skin. In muscle tissue, it serves as a major component of the endomysium.

Collagen constitutes one to two percent of muscle tissue, and accounts for 6% of the weight of strong, tendinous muscles. The fibroblast is the most common cell that creates collagen. Gelatin, which is used in food and industry, is collagen that has been irreversibly hydrolyzed. Collagen also has many medical uses in treating complications of the bones and skin.

Collagen occurs in many places throughout the body. Over 90% of the collagen in the human body, however, is type I. So far, 28 types of collagen have been identified and described.

The five most common types are:

Type I: skin, tendon, vascular ligature, organs, bone (main component of the organic part of bone)

Type II: cartilage (main collagenous component of cartilage)

Type III: reticulate ( the main component of reticular fibers), commonly found alongside type I.

Type IV: forms basal lamina, the epithelium-secreted layer of the basement membrane.

Type V: cell surfaces, hair, and placenta

What are the benefits of collagen?

#1 Improves the health of skin and hair

As we get older our bodies produce less collagen. You’ll notice looser skin, more wrinkles, and less elasticity. Increasing collagen levels can help your skin look firmer, increase smoothness, and help your skin cells keep renewing and repairing normally.

Studies have found that 2.5–5 grams of collagen hydrolysate used among women aged 35–55 once daily for eight weeks significantly improved skin elasticity and skin moisture. (Source)

#2 Repairs Joints 

Collagen may be beneficial to bones and joints in the same way it benefits the skin. By helping the body’s natural production of collagen and providing a bioavailable source of these amino acids, collagen may improve bone and joint health over time. A 24-Week study has shown that athletes consuming collagen hydrolysate can reduce parameters (such as pain) that have a negative impact on athletic performance. (Source)

#3 Reduces cellulite

If the level of collagen in your body is low and consequently your skin loses its elasticity, cellulite is more visible. Your skin is now thinner and cellulite becomes more evident. Improving your skin’s elasticity through collagen helps reduce that Woman's Worst Enemy.

It is important that you avoid following behaviors if you don’t want to destroy collagen in your body:

- Eating too much sugar. Minimize your consumption of added sugar and refined carbs.

- Avoid excessive sun exposure. Ultraviolet radiation can reduce collagen production.

- Don’t smoke, smoking reduces collagen production.

Where can you find collagen?

Collagen is found in the connective tissues of animal foods. For example, it's found in large amounts in chicken and pork skin. You can find collagen also in our nuMe products. If you are on a way to a NU you, you don't have to worry about your skin. nuMe products with collagen will increase skin elasticity and prevent saggy skin during weight loss.
