What is Collagen?

what is collagen?

Collagen is a protein found in the skin, muscles, bones, connective tissues, blood vessels and digestive system. It is the most abundant protein in the human body, making up 25% of the total proteins. It is also the most plentiful substance in the body after water. Collagen benefits for skin include optimal elasticity and tone, as well as replacement of dead skin cells. We also need collagen for joints to ensure proper pain-free function.

Collagens in the human body are strong and flexible, consisting of 19 amino acids with high levels of glycine, proline and hydroxyproline. Our bodies contain 20 types of collagen; 80-90% of them are categorised as Types 1, 2 and 3. The different types have different structures and functions. Types 1 and 3 are primarily found in the skin, tendons, ligaments and bones. Type 2 is a major component of joint cartilage.


The most abundant and the strongest type of collagen. It is made up of eosinophilic fibres that form skin, organs, tendons, ligaments and bones. It is also found in the gastrointestinal tract. It is essential for wound healing, maintaining skin elasticity, and binding tissue together to prevent tearing.

Primarily helps to build cartilage (located in connective tissues) by copying its profile using a combination of 18 amino acids. We need cartilage and collagen for joint health to help prevent age-related joint pain and arthritis.

Made of reticular fibres and is a major component of the extracellular matrix that makes up the skin and organs. It is usually found with Type 1 and so helps give skin its firmness and elasticity. It also forms blood vessels and heart tissues, which is why a deficiency is linked to a higher risk of ruptured blood vessels and early death.

Types 1 & 3 and Type 2 should not be combined due to their differing amino acid profiles. If taken together, they will bind and form a complete protein which the body does not recognise as collagen.


Collagen benefits us by giving the skin strength and elasticity, replacing dead skin cells, and in terms of joints and tendons, being the “glue” that holds the body together. The body’s collagen production begins to slow as we age. This natural degenerative process is responsible for signs of ageing such as sagging skin and wrinkles, as well as joint pain caused by weaker or decreased cartilage. Women may experience a reduction in collagen synthesis following the menopause. A considerable decline in collagen synthesis by age 60 is normal. Lifestyle factors such as smoking, a high intake of sugar and high levels of sun exposure also contribute to depleted collagen levels. Studies show that collagen-related diseases most commonly occur due to a combination of genetic defects, nutritional deficiencies, poor intake of collagen-rich foods and digestive issues which affect collagen synthesis.


Collagen is secreted by various cells in the body, mainly by connective tissue cells. It is found in the extracellular matrix; an intricate network of macromolecules (a molecule containing a large number of atoms) that determine the physical properties of body tissue.

In the middle layer of the skin (the dermis), collagen helps to form a fibrous network of cells called fibroblasts. New cells are able to grow on this network. Fibroblasts also play a role in replacing and restoring skin cells. Some collagens even act as protection for delicate organs such as the kidneys.


Reduces Joint Degeneration and Pain

When collagen levels deplete, tendons and ligaments are less able to move with ease which leads to swollen, stiff joints. It is vital we have enough collagen for joint health, to help the body move without pain. Collagen can be particularly beneficial for those with osteoarthritis and other joint disorders.

Helps with Leaky Gut Syndrome

This condition is characterised by toxins being able to pass through the digestive tract. By forming connective tissues, collagen helps break down proteins, soothe the gut lining and heal damaged cell walls with amino acids. Collagen can also help with inflammatory bowel disease, IBS, Crohn’s disease, ulcerative colitis and acid reflux. It aids the absorption of water within the intestines, keeping toxins and other substances moving freely out of the body.

Boosts Metabolism, Energy and Muscle Mass

Increasing collagen intake can power your metabolism by converting nutrients into lean muscle mass. Collagen and energy levels are closely related; glutamine helps maintain energy by fuelling the body’s cells. Glycine plays an important role in proper digestive and nervous system function. Arginine helps the body make protein from other amino acids to assist with muscle tissue repair, wound healing and proper growth and development.

Improves Skin, Hair and Nail Health

As we age, collagen production declines, causing noticeable physical changes. The skin becomes looser with more wrinkles and less elasticity. Marine collagen supplements can make skin look firmer and smoother and help cells regenerate normally. This also helps reduce cellulite, stretch marks, peeling/splitting nails and weakened hair. Collagen is scientifically-proven to be one of the best natural anti-ageing ingredients.

Supports Weight Management

Known to be among the most satiating macronutrients, proteins can prevent cravings and help people reach their fitness and weight goals. Collagen peptides are particularly renowned for their ability to help individuals lose or maintain weight when incorporated in weight management formulations. An in vivo study conducted in 2006 by the Laboratory of Physiology and Ingestive Behavior, INRA-AgroParis Tech (Paris, France), showed that Peptan is more effective than a standard dairy protein in weight management. A 2009 study demonstrated the improved satiating effect of collagen peptides on humans, in comparison to other proteins. The study showed that collagen peptides – taken alone or supplemented with tryptophan – are 30 to 50% more satiating than casein, soy or whey.

Collagen for Diabetes

Collagen protein may help to stabilise blood sugar in diabetics, helping to prevent energy crashes. And collagen contains high levels of glycine which has been proven to positively impact insulin secretion and blood sugar levels.

Protects Cardiovascular Health

Proline helps artery walls release fat build-up into the bloodstream to minimise accumulation. It aids tissue repair in the arteries and helps control blood pressure. It is also linked to the prevention of hardened arteries as it combats plaque build-up. In addition, arginine assists with nitric oxide production which allows for better widening of the arteries and relaxation of muscle cells and blood vessels.

Heal Your Wounds Faster

Collagen helps migrate numerous types of cells, including fibroblasts and keratinocytes, to the wound, which plays a major role in boosting tissue growth in a wound bed. These properties can help assist clinicians with debridement of infected tissues in a wound and encourage natural growth to occur.

Can Improve Liver Function

Glycine helps detoxify the body, protect the liver, improve blood flow and keep the heart young. It minimises damage caused to the liver following absorption of alcohol and toxic substances.

The benefits of drinking collagen are many. Medical studies have shown that liquid extracts and supplements are absorbed more quickly than pills, and are more digestible. The nutrients within don’t need to be broken down, so liquids are more potent than pills. They are also easier to swallow, especially for children and the elderly.

The nutrients in liquid supplements are absorbed in seconds, while pills can take hours. What’s more, only 10-20% of the nutrients in pill supplements are actually retained. With liquids, 98% of the nutrients are utilised.

How To Take Collagen Supplements

Take the recommended 10,000mg dose daily, with or without food. For good results, use continuously for 4-8 weeks. For optimal and sustained results, use continuously for 12 weeks.
