Collagen vs Collagen Peptides: What's The Difference?

We’re often seen talking about collagen and collagen supplements, but what about collagen peptides? Well, these microscopic molecules are not just a by-product of collagen – they are the reason that taking collagen is so good for your skin!

Let’s break the details of this magical molecule down together, shall we?

What are collagen peptides?

Collagen peptides are the result after the molecular bonds of collagen strands have been broken down, leaving smaller, more easily digestible molecules. 

The breaking down process of collagen into collagen peptides is achieved by something called ‘hydrolysis’. Hydrolysed collagen peptides are those which have undergone a chemical process where the collagen’s structure is changed, either by heating the collagen and adding enzymes (this is how we hydrolyse our marine collagen supplements) or by adding an acid to the collagen. 

What’s the difference between collagen and collagen peptides?

In its natural state, collagen is too large to be absorbed and wouldn’t be effective in your body. In fact, if collagen without hydrolysis were to enter the bloodstream, the molecules would eventually be destroyed by the gut, eliminating the collagen’s benefits completely. 

However, collagen peptides easily pass through the gut lining and are absorbed instantly by the body (this means they are ‘bioavailable’). This is because native collagen – get ready for more science - is made of large triple helix chains of amino acids. In other words, it’s not soluble (it isn’t able to be dissolved in the body). 

Once collagen peptides are successfully digested, they can then act as building blocks, renewing bodily tissues, such as skin, bones and joints. Additionally, they may act as a messenger to the cells to trigger the natural production of more collagen, thereby supporting our tissue structure. As such, taking collagen most likely means producing more collagen – exactly what you would be looking for when looking to reduce the appearance of wrinkles!

Don’t just take our word for it though. A study in 2023 highlighted that taking collagen peptides can be beneficial in reducing wrinkles, as well as increasing skin elasticity and firmness.

Can I drink collagen peptides?

You absolutely can! Collagen peptides are soluble in cold water, highly digestible and ready to be absorbed by our bodies. 

Due to hydrolysis breaking down larger collagen molecules into a smaller, more digestible form, they are much easier to consume and are therefore considered the best form of collagen for ingestion. Collagen peptides are what you will find in digestible forms of collagen, like liquid collagen, collagen powders, and collagen tablets. 

What are the benefits of taking collagen peptides?

Different cells in our body tissues are responsible for the production of collagen. The cells use specific amino acids and peptides as building blocks for the production of the large collagen helix structure. This is then organised into the strong fibres that provide structural tissue support and flexibility.

As we age, our bodies naturally begin to produce less collagen, and the signs of ageing start. From around the age of 25 and accelerating in our 40s, loss of collagen affects all of our connective tissues. This is one reason why many people start taking collagen supplements to reduce the appearance of wrinkles in their 40s, if not before.

Collagen peptides supplements support the body in replacing lost collagen. As collagen is found in skin, cartilage, bones, and connective tissues, taking collagen peptides has myriad benefits for these key areas.

Collagen peptides benefits for our skin

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

So, while it won’t magically clear your signs of ageing, taking collagen peptides for your skin can help to hydrate and boost a youthful complexion.

Collagen peptides benefits for our bones

You may not know or feel it, but our bones are constantly being broken down and rebuilt – a process that keeps them strong and healthy. When we’re young, this rebuilding process is faster than the breakdown, so our bones grow stronger.

But as we age, the breakdown of bone tissue starts happening faster than the rebuilding process. As a result, our bones become weaker and more fragile over time. However, as collagen peptides play a vital role in bone health and structure, our natural collagen structures can help support the formation process.

Collagen peptides benefits for our muscles

A gradual loss of muscle mass and strength caused by ageing can affect our balance, gait and overall mobility. Due to collagen being a protein, collagen peptides contribute towards the healthy maintenance of those muscles.

Can I get face cream with collagen peptides?

Oh yes! Our range of collagen face creams is positively packed with high-quality collagen peptides – the same of which you would find in our marine collagen supplements. Use the collagen day cream first thing in the morning and collagen night cream last thing at night for hydrated, firmer, visibly glowing skin.
