What is Collagen? And what can it do for you?

Beautiful skin on the outside needs a healthy foundation on the inside. A growing body of research, has shown how certain nutrients can make a significant contribution to skin health. Also referred to as ‘Beauty from Within’ solutions, nutricosmetics are nutritional supplements which support the structure of the skin from the inside. Peptan collagen peptides are the first nutricosmetic ingredient to show skin restructuring effects, as proven in recent studies published in the Journal of Cosmetic Dermatology.

Peptan collagen provides multiple proven health benefits by acting as building blocks for healthy joints, bones and muscles as well as skin.

So what is collagen and what are the benefits?

Collagen is a protein found in animals and made up of amino-acids. Since ancient times, collagen has been known to benefit human health. For centuries, people have been consuming collagen in the form of bone broth to support their joint and bone health and in more recent times, to promote healthier hair, skin and nails.

Collagen and its role in the human body :

Collagen is the major protein in the connective tissues of the body. It holds all living tissues together and ensures the integrity, elasticity and regeneration of skin, cartilage and bones. It is the most abundant protein, representing almost 30 per cent of all human protein content. in simplest terms, it’s the “glue” that helps hold our body together.

What happens when we age?

Collagen production in our body peaks around the age of 20, and as we age, the body’s production of collagen metabolism slows down causing a gradual deterioration of collagen fibers in all connective tissues. Other lifestyle factors such as eating fast-food diets high in sugar, smoking, alcohol consumption and high amounts of sun exposure also contribute to the depletion of our collagen levels in the body as time goes by. This degradation process will affect different parts of our body –


As skin cells become less active, the collagen network that provides skin firmness and structure breaks down. Skin becomes dehydrated and thinner, plus lines, wrinkles and deep furrows start to appear.


Bone turnover becomes imbalanced, that means there is more bone loss than bone formation. This causes bones to become more fragile and easier to break.


Lower levels of collagen and other matrix components can cause loss of cartilage and joint function. This results in joint discomfort and pain.

Different Forms of Collagen, digestibility and bioavailability :

Collagen is a safe and natural ingredient which can be obtained in different grades. It can be found in products such as bone broth or gelatine based desserts.

Gelatin is a healthy food, but the unique benefits that collagen offers are not easily obtained by eating gelatine alone, not to mention the sugar content that accompanies jelly desserts.

Breaking gelatin into smaller chains (by hydrolysis), produces collagen peptides (small chains of amino acids), which are easier digested and absorbed by the body. Consuming collagen peptides allows your body to maximizes the benefits that collagen has to offer.Unlike native collagen, collagen peptides are highly digestible and bioavailable. Studies have demonstrated that over 90% of the peptides are digested and absorbed within a few hours after meal.

This rapid absorption ensures the effective delivery of the essential peptides and amino acids to their site of action within the body.

Collagen as a unique protein with key amino acids :

Proteins are essential nutrients for our body. Proteins are long chains made of amino acids linked together. Consumption of collagen peptides will help to supply your body with amino acids needed as building blocks to renew tissues such as skin, muscle, bones and joints. It has been proposed that collagen peptides may act as a messenger to the cells and trigger the synthesis and reorganization of new collagen fibers therefore support skin tissue structure.

Collagen peptides are characterized by a high level of the key amino acids: glycine, proline and hydroxyproline, which represents around 50% of the total amino acid content. Hydroxyproline is unique to collagen. The amino acids in collagen are the same as found in skin, joints and bones. This very specific composition of amino acids provides collagen peptides with unique biofunctional properties that cannot be found in other protein sources.

Role of vitamin C :

Vitamin C is a co-factor which supports the production of collagen in the body. Therefore, it is important to ensure that you have sufficient vitamin C in your diet to boost the collagen synthesis.

Collagen peptides’ health effects

Collagen makes up 70% of the skin’s dry mass skin content. As a key component of the skin’s structure, collagen fibers also provide the infrastructure for elastin, which maintains the skin’s elasticity, and for hyaluronic acid to trap moisture.

As we age, the number and activity of skin cells that produce collagen decreases, the skin then becomes dry and thinner as the collagen network that provides skin firmness and structure starts to break down.

A recent clinical study showed that Peptan collagen peptide consumption effectively improved skin structure: the fragmentation of collagen in the deep layers of the skin was clearly reduced already after four weeks and decreaesd by 31% after 12 weeks. At the same time the density of the collagen layer increased providing more strength to the skin (Asserin et al., 2015). Peptan further increased skin moisture by 28% after 8 weeks in another clinical study (Asserin et al., 2015). This restructuring of the skin is key to bringing anti-aging benefits and a more youthful appearance.


Collagen represents around 90% of organic bone mass and provides a flexible framework and flexibility to which calcium hydroxyapathite is added to provide strength. A cycle of continuous bone formation and breakdown replaces approximately 15% of bone mass in healthy adults each year. When this balance tips towards faster bone loss and slower bone formation, the bone density decreases leaving the bone more fragile.

Peptan collagen peptides promote bone health by stimulating bone renewal, maintaining bone mineral density and improving bone solidity and strength.


Collagen fibers make up 70~95% of cartilage and are responsible for its structure and strength. Aging and high impact or load on joint can cause wear and tear of the cartilage. Symptoms include joint discomfort, tenderness, stiffness and locking.

Peptan collagen peptides have been proven to stimulate cartilage cells synthesis, producing increased aggrecan and collagen. A recent study (Jiang et al., 2014.) shows that an intake of 8g/day of Peptan can reduce joint discomfort and improve joint flexibility and function.

Collagen peptides such as Peptan are bioactive and pure protein, and as a protein they can help contribute to many different health benefits.
Hair & Nails :

Collagen provides the structural foundation for skin and nails. When ingested, amino acids from collagen peptides are absorbed and used by hair follicle cells to produce keratin protein for healthy hair. Fingernails and toenails are also made of keratin, and rest on a nail bed made of skin dermis.

Post work out recovery :

To ensure optimum muscle regeneration, physically active people need a sufficient availability of amino acids to enable muscle synthesis during recovery. A high protein diet just after exercise may enhance muscle anabolism, replacing lost proteins and helping to maintain and restore the protein content of the muscles while also reducing the recovery time.

Satiety effect :

Providing a high satiety effect, Peptan collagen peptides are an excellent protein source to control appetite and moderate cravings.

Daily intake :

In order to continuously boost the production of collagen in the body, it is recommended to consume collagen peptides on a daily basis. Based on Peptan clinical studies 5 to 10 gram a day is suggested. If you have a medical condition or are pregnant, please consult your medical doctors or health care professionals.

Are collagen peptides safe?

Collagen peptides such as Peptan are a pure and bioactive protein, derived from 100% natural source and free from any side-effects.

How much time is needed to see the first result?

Most studies show positive health effects on skin and joints within 1-3 months of daily intake. However it is vital to keep up a regimen of daily collagen intake to ensure efficient metabolism and optimal effects.
