What is Collagen?

Collagen is one of the most abundant proteins in the human body making it vital for the strength, elasticity and plumpness of our skin. It is the major building block in our tendons, ligaments, cartilage, bones, blood vessels and gut. Our body naturally produces collagen while we are young keeping our skin smooth and our bodies strong.

Unfortunately, from around our mid-twenties, this natural production of collagen slows and we start to notice the physical signs of ageing. This include’s fine lines and wrinkles, loss of plumpness and hydration in the skin, and weaker bones and joints.

At Puresque, we believe that youthful, glowing skin and a strong, healthy body should have no age limit. This is why we have created one of the highest quality marine collagen supplements on the market today. It is easily and effectively absorbed by the body to help replenish your collagen levels from within so you can enjoy beautiful skin and a healthy body at any age.


What makes ours different?

Our Replenish Blend is made using 100% sustainably sourced (MSC approved), wild caught, deep-sea cod from the crystal clear waters of the North Atlantic Ocean. It is an all natural, raw material with an extremely low heavy metal content making it one of the cleanest and highest quality marine collagen supplements on the market today.

Marine Collagen
Scientific research has found that the marine collagen peptide is the most bioavailable form of collagen for your skin, being absorbed up to 1.5 x more efficiently than other types of collagen such as bovine or porcine sources. Marine-sourced collagen is also a type 1 collagen, the main type of collagen in the human body and the most effective in providing the foundation for beautiful skin, strong connective tissue and sturdy bones.

Our marine collagen replenish blend is 100% hydrolysed meaning the proteins are broken down into peptides which are easily absorbed by the body. This ensures maximal absorption and rapid utilisation of the ingested collagen.

Added Vitamin C
Collagen and Vitamin C work very closely together. Vitamin C hydroxylates key amino acids in the body which are required for the production of new collagen. Recognising this relationship, we have added high quality, natural vitamin C to our blend to support and encourage the creation of new collagen in the body so that you are getting the optimum benefits of our Marine Collagen Replenish Blend in every serve.

The Impact of Marine Collagen Peptide on Personal Appearance

There is no denying that collagen supplements have been around for many years but only recently have people really started to recognise just how powerful taking an oral collagen supplement can be for your skin and physical health. Here are some benefits of taking a daily serving of marine collagen both from scientific evidence and personal experience.



Collagen is highly recognised throughout the beauty and skincare industry as a powerful anti-aging ingredient, but what many people don't realise is that collagen needs to be replenished from within in order to see the benefits on the outside. The amazing results I saw in my skin after only two weeks of implementing marine collagen in my daily diet is one of the main reasons I am so passionate about this product and so excited to be able to share it with you!


Marine collagen has amazing anti-ageing benefits for the skin. A study done on a group of woman aged 35-55 demonstrated that marine collagen gave the skin a significant increase in elasticity. (Proksch, Segger, et al., 2014)

Elasticity is what gives skin that plump, spring-like effect that starts to degenerate as we age. By bringing elasticity back into the skin, you are providing the essential tool it needs to look and feel younger.

Fine Lines & Wrinkles

Taking a daily marine collagen supplement can significantly help to smooth fine lines and wrinkles. A group of scientists from the University of Kiel, Germany, in a recent study, demonstrated a significant reduction in skin wrinkles after daily consumption of a collagen hydrolysate. (Proksch, Schunck, et al., 2014)

It’s almost like a natural botox! As we age, we all start to see those fine lines and wrinkles beginning to appear. This is caused by the natural breakdown of collagen and elastin in the skin. Replenishing your natural collagen levels will give you effective anti-aging results naturally. It can significantly help to smooth those fine lines, reduce deeper wrinkles, and plump the skin for a radiant, youthful complexion.

Taking a marine collagen supplement will help give skin that beautifully hydrated glow. A clinical dermatological study done on 20 women aged 40-55 for the hydration effects of consuming a marine collagen peptide supplement over an 8 week period showed impressive results. The study showed hydrolysed marine collagen peptide to be easily absorbed and led to a significant increase in skin moisture. The average improvement in facial skin moisture was 34.8%.

Dehydration in the skin is a common condition that can be caused by not drinking enough water or skin exposure to harsh weather conditions such as the sun or being under constant air-conditioning. It is what can make the skin look dull and lifeless. Common signs of dehydrated skin include fine lines over the forehead, eyes, cheeks and lips. Drinking enough water daily can help to improve dehydrated skin but many people may find they need a bit of extra help. Taking a marine collagen supplement daily can help increase moisture and hydration in the surface of the skin which will reduce those fine lines and keep your complexion looking fresh and hydrated.

Hair & Nails

Collagen protein is the major building block of our hair and nails. If you are one who suffers from weak, splitting nails or thinning, damaged hair, taking a collagen supplement daily may help to replenish those cells that strengthen nails and support healthier hair growth.

Gut Health

Leaky gut syndrome is a growing problem that can cause people to feel tired, moody and bloated with an upset stomach when having eaten certain foods. This occurs when the lining of the intestines become damaged causing toxins, undigested food and bacteria to leak into the bloodstream which can cause an auto-immune reaction. Because the connective tissue within the gut lining and digestive tract is made up of collagen, replenishing these cells with a fast absorbing collagen supplement can help rebuild and repair the intestinal lining. It does this by healing damaged cell walls and infusing them with healing amino acids to help strengthen the gut and reduce symptoms associated with leaky gut.

Muscular-Skeletal System

Collagen is a major structural protein in the body found mostly in the dermis, bones, cartilage and tendons. There are many scientific and preclinical studies showing various positive effects that taking a marine collagen peptide supplement daily can have on tendon flexibility, ligament stability, muscle and bone integrity, and bone metabolism.  

Ligaments & Tendons

Our ligaments and tendons rely on collagen to maintain their strength and flexibility. Unfortunately, due to the natural degeneration of collagen as we age, our ligaments and tendons can become weaker over time making them more prone to damage. A study done in 2013 showed that taking a collagen peptide supplement can significantly increase the expression of collagen types 1 and 3 in fibroblasts from ligaments and tendons of humans. This means that collagen peptide may help to treat and prevent changes and degeneration in ligaments and tendons as we age.

Bone Integrity & Metabolism 

Many studies have shown that taking a marine collagen supplement can have various positive effects on bone integrity and bone metabolism. A study done in 2014 concluded that fish collagen peptides were shown to up-regulate the gene expression of collagen-modifying enzymes and this effect led to increased collagen synthesis and positive effects on collagen quality and matrix mineralisation in the bone cells.

Our bones are naturally made up of around 90% collagen so it is essential to keep our collagen levels replenished in order for our bones to be healthy. One serving of marine collagen daily may help to support bone health and assist with increased bone and mineral density, increased bone size, less brittle bones, and the stimulation of osteoblast activity.

Muscles Mass & Weight Management

Collagen peptide sourced from fish has a unique amino acid profile. It is very high in the amino acids glycine, proline and hydroxyproline. These amino acids are essential for stimulating cells in the body that lead to the production of new collagen. 

Collagen is used by the body to strengthen connective tissue which leads to better muscle mass and definition. A recent study done on an elderly man with sarcopenia showed that taking a marine collagen supplement in combination with resistance training is effective in improving body composition by increasing fat-free mass and muscle strength and reducing fat. (Zdzieblik et al. 2015)

Most of us are aware that as we age, our metabolism naturally begins to slow and our body’s ability to build and maintain muscle becomes more work than it was in our late teens and early twenties. One of the main reasons for this is the fact that our bodies naturally produce less collagen as we age. By taking a marine collagen supplement in conjunction with weight training and exercise, you are providing your body with the essential amino acids it needs to rebuild muscle mass which in turn can help increase your ability to burn fat.
