The Foundation of Healthy Skin: Collagen

Healthy, "normal" skin has a smooth, soft surface, is plump and moist, and has a nice even, unblemished tone and colour.

So why does our skin change when we get older?

To get an answer to this question, we need to go below the surface, beneath the epidermis (the outermost layer of skin) and into the derma - dermatologists refer to it as the "extracellular matrix". This is where all of the real action goes on.

There are three main components to maintaining healthy skin, and when we're young we they occur in high levels in our skin. These three make up your extracellular matrix to provide a healthy foundation for smooth, vibrant and strong skin:


this provides your skin it's firmness and smoothness (over 70% of your skin consists of collagen)

Hyaluronic Acid

which keeps your skin moist and hydrated (~50% of your body's HA is found in the skin)


which supplies your skin with it's elasticity and rebound

Collagen, being 75-80% of your skin in total, is found plentifully within the body from a young age. The declining production in collagen is what starts to cause sagging, wrinkly and dull skin.

But you need to know that it's not just internal factors, but external factors too that can damage the collagen in your skin. This causes undesirable accelerated skin aging which leads to problems like:

Bumpy Skin

Skin Blemishes

Excessive Wrinkles

Peeling Skin

Irritated Skin

Droopy Skin

Why Does Our Skin Start to Wrinkle as we Age?

Intrinsic aging is another name for the natural aging process that happens over the years regardless of external influences. From the age of 20, we begin producing 1-1.5% less skin collagen on average every year, and the loss only accelerates from there. Resulting from this our skin starts to become thinner and more fragile. There's also a similar decline in your skin's production of elastin and hyaluronic acid.

Without supplementation, by the age of 40 we produce, on average, 25% less collagen than we did in our youth, and then by the age of 60, our bodies can be producing as much as 50% less collagen.

Turning Back the Clock

The only way to adequately replace lost collagen is from the inside out.

It's a simple two-part system that address both the production of new collagen and ensuring that that collagen is absorbed by your body.

Getting the right collagen

Human skin is made up of Type 1 collagen. Most collagen powders include the wrong form of collagen for your skin, instead settling for cheap, ineffective Type 3 Bovine (cow) collagen.

Maximising the absorption of that collagen into the body

We need to make sure the collagen we do take is absorbed by the body. Collagen supplements that aren't absorbed by the body are a waste of money and time.

Only Marine Collagen+ provides all of this... one easy to take capsule, replenishing your lost collagen and turning back the clock on your skin for a youthful, glowing look!

Step 1: Choosing the Right Type of Collagen

Shopping for collagen can get very confusing. There are so many different option, and collagen marketers don't make it any easier. However, it's not as complicated as it's made out to be, as long as you shop with the desired benefit in mind.

Here's a breakdown of the most important things you need to know when shopping for collagen. You see, there's actually 5 different types of collagen, but most collagen is type 1, 2, or 3.

The most important thing you need to know is that up to 80% of your skin is Type 1 collagen, this helps minimise fine lines and wrinkles. The most abundant source of Type 1 collagen is by far, Marine Collagen.

Hydrolyzed Collagen Peptides

To be technically correct, what collagen powder consists of is "collagen peptides". For collagen to be best absorbed by the body, it first needs to be broken down into smaller units of protein, called peptides. These tiny peptides are more easily absorbed by your body and are what your body needs to more efficiently make new collagen.

Hydrolyzed collagen is just collagen that has been broken down into those smaller peptides. Hydrolyzed collagen is much more popular than other sources of collagen such as bone broth or other gelatin forms because it's so much better at being absorbed by your body.

Best Collagen for Joints

Type 2 collagen makes up a majority of the collagen in your joint cartilage. It can be found in your spinal disks and in your connective tissue that protects your bones at the joints. If you're looking for joint health, then the best source of Type 2 collagen is from chicken cartilage.

Best Collagen for Gut Health

Type 3 is found largely in the intestines, muscles and blood vessels. Many people take it for muscle building or gut health repair. The most common Type 3 collagen is bovine collagen.

But as a warning, Bovine collagen peptides literally come from ground up hooves, hidesm nerve tissues and other parts of the cow that aren't needed. These are also the parts that can carry diseases and can make you very sick. So be careful when shopping for this type of collagen. Do your research first for your safety.

Best Collagen for Skin

Marine Collagen is mostly Type 1, which makes up the majority of collagen in your skin. It's the most skin specific of all the collagen types.

Marine collagen also has the smallest particle size of all the other types of collagens, this makes it far easier to absorb than bovine or other types of collagens. In fact, it's a full 1.5 times easier to absorb than bovine, the results speak for themselves.

Koru's Marine Collagen+

Clinically Proven Results!

Our Marine Collagen+ is sourced exclusively here in New Zealand form some of the deepest most pristine waters in the world. Marine Collagen+ is 100%New Zealand Made and 100% natural, because to us, second best simply isn't good enough.

Research has shown that taking one capsule of Marine Collagen+ is the equivalent to taking 3 capsules of ordinary collagen.


Step 2: Maximising Absorbtion

This step is most often overlooked by manufacturers. Collagen supplementation by itself can only go so far. In fact if you don't take the right type of collagen, there's no scientific evidence that it can help your skin any more than having a healthy diet.

We at Koru Nutrition saw this and realised that plain collagen supplements and powders don't work and are wasting your money! So we found a way to fix the problem.

Kiwifruit Enzyme

With years of research as a foundation, we developed a specific formulation of Marine Collagen+ containing a unique active enzyme sourced from kiwifruit. This kiwi fruit enzyme is scientifically proven to enhance the absorption of collagen within the body.

With 270% greater bioavailability, Marine Collagen+ enters the body 3 times faster than regular collagen, and twice as fast as other marin collagens.
