What is Collagen

COLLAGEN is the body’s most important building block accounting for roughly a third of its protein composition.


COLLAGEN occurs naturally in our body.  It promotes  gut health, it provides firmness and elasticity to our  skin, strengthens nails and hair, it builds muscle, strengthens bones, maintains joint health, and  supports healthy ageing.

COLLAGEN provides structure to bones, skin, muscles, tendons, and ligaments. Essentially it is the ‘glue’ that holds all these things together and its name comes from the Greek word ‘Kólla’ which means glue.

COLLAGEN production in our body peaks in our early 20s, drops by the age of 30 and from 40 its decrease accelerates. We can help preserve and protect collagen levels by eating less sugar and avoiding both smoking and sunburn.

While our grandparents were happy to stew up the less attractive parts of animals, boil bones for broth, and delight in anything caught on a fishing line or collected along the

coast, today we tend to opt for main cuts of muscle meat or avoid meat all together. Consequently we have lost an important source of collagen in our diet. 

It is important to look for Hydrolysed Collagen.    

Collagen is a triple helix built from three amino acid chains.  Put through a natural enzymatic process, the native collagen (bovine hide or fish skins) is softened and Collagen Peptides (also known as Hydrolysed Collagen) are safely released from their bonds. These peptides contain the exact same set of amino acids and nutrients as collagen but are shorter chains.  They are bioactive, they can dissolve and are more easily digested.  Once absorbed into the bloodstream they can travel around the body and influence activity of cells in multiple ways. 

Key attributes to taking supplements

Beauty within is the foundation of a more radiant beauty on the outside.  A growing body of research has shown how certain nutrients, can significantly improve skin, nail, and hair health. 

Maintaining Healthy Joints and Bones supports an active lifestyle and helps maintain mobility in senior years. Advancing age and regular exercise from a young age can increase the ware on the body and highlight the importance of nutrition and the function that proteins play in maintaining healthy and flexible joints. 

Sports Nutrition and Recovery maintain and improve performance and fitness.  Intense training puts a strain on muscle fibres and the wrapping sheath of connective tissues raising the risk of injury.  It is therefore important that strength and muscle mass are maintained, and the body is given sufficient time to heal before more training.  Nutrition and the function of proteins play a key role in improving athletic performance, reducing recovery time, protecting connective tissues, supporting healthy joint maintenance, and helping to reduce the risk of injury.

How do you find your inner strength?

For centuries, collagen has been a champion in achieving beauty from within. Aside from being an essential skin component, collagen is also a key element in our musculoskeletal system. This article underscores the importance of collagen for mobility and sports performance, and how to counter the progressive decline of collagen with age with Peptan® collagen peptides, all to ensure an active and healthy lifestyle and boost inner strength.


Collagen: holding our bodies together

Collagen is the most abundant protein in our bodies and the main structural component of the connective tissue that supports and protects our organs. Collagen is found throughout the body, from skin cells and blood vessels to the entire musculoskeletal system including tendons, ligaments, cartilage, muscles, and bones


However, collagen production declines with age or owing to lifestyle and stress as well as exposure to UV radiation and pollution. This reduction in collagen affects our bodies in different ways. Skin, for instance, becomes dehydrated and thinner, and visual signs of aging such as fine lines and wrinkles appear. Muscles lose strength and function, affecting balance, gait, and overall mobility. Wear and tear of joint cartilage increases discomfort. In addition, bones become more brittle and fragile as bone maintenance decreases with age. To sum up, collagen loss weakens the musculoskeletal system, making an active lifestyle more strenuous and increasing the risk of injuries. 

To investigate the effects of collagen peptides on supporting our body and boosting our inner strength, Rousselot carried out several scientific studies to understand the mechanism behind and how supplement collagen peptides can help promote health benefits.

What do bioavailability and bioactivity mean for boosting your inner strength?

Aside from being absorbed and becoming bioavailable, collagen peptides are also bioactive. Bioactivity refers to the effect a nutrient has on the function of a tissue (also referred to as messenger effect). In the case of collagen peptides, after being absorbed, they trigger the synthesis and reorganisation of new collagen fibres, improving the collagen matrix, and positively affecting skin, bones, muscles, and joints as demonstrated in scientific studies.[2,3,4,5,6,7,8,9]
