Collagen is the most abundant protein in the human body; accounting for approximately 25% of the body’s protein mass. As a major component of connective tissue, it can be found in the skin, muscles, ligaments and tendons and a wealth of recent research has demonstrated benefits to gut integrity, ageing skin, bone mass and joint health.

What is important to realise, however, is that there are many different types of collagen – each with their own biological function.  To date, over 29 different types of collagen have been identified, with types I, II and III being the most prevalent within the human body – and it is type II collagen that is a major component of the cartilage in our joints.

Cartilage is a firm, gel-like substance which covers the ends of bones. Its primary function is to provide cushioning and reduce friction between bones as they slide over or against each other. Collagen type II is the main structural component of the cartilage matrix, accounting for around 60% of the cartilage and providing structure, firmness and resistance to compression.

Collagen can be found in animal proteins like eggs, chicken, meat and bone broth. We can also synthesise collagen from certain amino acids and nutrients such as vitamins A, C and copper, but as we get older, our ability to produce collagen depletes, which can contribute to wear and tear and degeneration of the cartilage in the joints – and taking a collagen type II supplement is one possible strategy to mitigate this decline.

When considering a collagen supplement, the form it takes is very important for its therapeutic role. Hydrolysed collagen, or collagen peptides have been partially broken down, or “pre-digested” meaning that they are effectively absorbed from the digestion into the bloodstream. Peptan IIm is a form of hydrolysed collagen type II which has been specifically formulated with joint health in mind. It has been matrixed with chondroitin sulphate and hyaluronic acid, making it identical to the composition of cartilage in humans. As a natural source of collagen, it can stimulate the synthesis of collagen within the body, while also providing the building blocks necessary for joint support.

Evidence has shown that supplementing with Type II collagen can improve overall joint health, reducing inflammation, increasing lubrication, decreasing pain and stiffness in those with osteoarthritis, as well as providing protection to the cartilage from further degeneration.
