It is the key to a healthy and active life. It keeps your joints strong, powerful and flexible, and allows you to enjoy your favourite sport - whatever your age.

Type 2 collagen will help you keep your joints (and more) in great shape for many years to come. That's why, together with pharmacist and educator Ilona Krzak, we're going to uncover the potential it holds for you.

Collagen type 2 is a great way to keep your joints in great shape for many years to come.

From this article you will learn:

What type 2 collagen is.
Why type II collagen is important for your body.
What are the most important sources of type II collagen.
How you can rebuild collagen in your knees.
What collagen preparations are recommended by experts.

What is type 2 collagen?

Collagen type 2 is a protein naturally found in the body. It is one of the main building blocks of joint cartilage, helping to maintain its flexibility, strength and ability to withstand pressure and friction during movement. It is what keeps your joints functioning properly.

And now you will see what the more specific terms that often appear in the context of collagen mean:

Hydrolysed collagen type 2

Hydrolysed type 2 collagen has gone through a whole process of hydrolysis, in which it has been broken down into smaller molecules called peptides . This makes it much faster and easier to absorb than natural collagen, which has larger molecules.

Hydrolysis is commonly used in the preparation of food products - among other things, it makes infant formula milk safer and less allergenic .

Research confirms that hydrolysed collagen relieves symptoms associated with osteoarthritis .

See also:

Native collagen type 2

Native type 2 collagen is the unprocessed, natural form of collagen that occurs in living organisms and has not undergone any processing - thermal or chemical . Native type II collagen - unlike hydrolysed collagen - retains its original structure.

Non-denatured type 2 collagen

Non-denatured collagen is simply natural collagen.

Dr Witold Tomaszewski — .
Witold Tomaszewskidoctor of medical sciences
.

By the way: have you ever eaten hard-boiled eggs? So you ate denatured egg whites. Have you roasted a turkey? Same thing. Virtually every protein we eat is denatured (unless - like Rocky Balboa - you drink raw eggs).

Research suggests that the protein is denatured.

Research suggests that non-denatured type 2 collagen is more effective against arthritis than its denatured form .

The use of native collagen preparations can lead to the development of so-called immune tolerance, which can reduce inflammation and degenerative processes in joints .

Where does type 2 collagen occur?

Type 2 collagen is mainly found in the articular cartilage, which is located between the bones in the joints, providing cushioning and promoting mobility. In addition, it is also found in the auricle, nasal septum and intervertebral discs .

Type 2 collagen makes up about 50% of the protein in articular cartilage and - depending on age - up to 80-90% of all the collagen there .

What does type 2 collagen help with and what is it responsible for? Properties and effects

Type II collagen plays a key role in maintaining the elasticity and strength of cartilage in joints, and also supports their regeneration . It is also responsible for joint cushioning - type 2 collagen forms a reticulated structure in cartilage that allows joints to be loaded and relieved during movement, thus protecting bones.

Type 2 collagen can help reduce joint pain and relieve inflammation. Some doctors also prescribe it to help with arthritic conditions and joint diseases, such as gonarthrosis, arthritis or rheumatoid arthritis (RA).

Collagen makes it possible for you to walk - or run - through life without pain.

A small dose of type 2 collagen - just 40 mg - is enough to bring visible results in the treatment of arthritis or RA.

Ilona Krzak Master of Pharmacy

What is the difference between type 1 and type 2 collagen?

Both types of collagen are crucial to the functioning of the body, but differ in occurrence and distribution, function and structure .

Collagen type I is mainly found in joints, tendons, ligaments, bones and teeth, forming quite thick and compact structures. Type 1 collagen provides mechanical strength and tensile capacity to many tissues.

Type II collagen forms thinner bonds and is found primarily in articular cartilage. It helps to maintain its integrity, elasticity and resilience, supporting joint health.

Collagen type II is a key component of joint health.

Collagen supplements - ranking the best supplements

Collagen loss can be affected by internal factors (e.g. genetics) or external factors (e.g. a diet low in protein, overexposure to the sun, air pollution or overly strenuous physical activity.

Collagen loss in osteoarticular tissues and skin is associated with age, hormonal profile, obesity, inflammation, lack of exercise, overloading mechanical damage to joints.

Ilona Krzak Master of Pharmacy

Collagen supplementation will help you to replenish collagen, but it won't work wonders on its own if you don't help it. The specific effects and benefits will also depend on factors such as lifestyle and diet.

FAQ

What is the best absorbed collagen?

Collagen bioavailability depends mainly on the collagen source and the degree of processing. Fish collagen (or marine collagen) has the closest structure and structure to human collagen, making it better absorbed than, for example, beef collagen .

Collagen in gelatine, which is a pre-processed form of raw collagen, is absorbed better than raw collagen itself (good luck chewing on raw bones and skins!). Hydrolysed collagen has been broken down into smaller molecules - collagen peptides - so it's quicker and easier to absorb, and you get more benefits.

If you care about a clear answer, then know that probably hydrolysed fish collagen is the best absorbed form of collagen.

Is collagen with hyaluronic acid a good combination?

Yes, the combination of hyaluronic acid and collagen can provide many benefits primarily for skin and joint health .Together they can, among other things, reduce wrinkles, hydrate the skin and add radiance, as well as improve joint mobility and reduce pain.

Check out fish collagen with hyaluronic acid and vitamin C from Sundose°.

Is collagen and gelatine the same thing?

No, although collagen and gelatine are closely related. Collagen is a structural protein that you find in skin, tendons and bones, among other things. Gelatin - in simple terms - is a form of collagen that you obtain by cooking animal bones, skin and cartilage. In this process, collagen is initially broken down into smaller molecules. Hydrolysed collagen is the product of further processing of the youth protein to increase absorption and availability. (When you cook food, you do something relatively similar - you pre-digest the food with temperature to make it fast and digestible).

Both substances contain valuable amino acids - in particular proline and glycine - which benefit the skin, hair, nails, joints and digestive system.

What is important - collagen in hydrolysed form - is better absorbed than gelatine. And that's exactly the form to look for in collagen supplements.

How to rebuild collagen in the knee

Rebuilding collagen in the knee will improve joint function and relieve pain. Here are some ways you can do this:

Supplement - look for supplements with type II collagen, glucosamine and hyaluronic acid, which is the main component of synovial fluid.
Enrich your diet with protein, vitamin C, calcium and phosphorus - these will stimulate collagen production, improve absorption from supplements and improve joint function.
Climit alcohol and quit cigarettes - stimulants destroy collagen in the body and negatively affect overall health.
Get to a healthy weight - the less you weigh, the less strain you put on your knees and other joints.

If you have more serious problems, consider:

Medications and delivery injections - taking medications, medical devices and giving ampoule injections should always be done under the guidance of a doctor or pharmacist.
Physiotherapy - the administration of medications, medical devices and giving ampoule injections should always be done under the guidance of a doctor or pharmacist.
Physiotherapy - exercise will improve joint mobility.

Is fish collagen good for joints?

Of course! Fish collagen - also called marine collagen - has the closest structure and structure to human collagen. As a result, it is well absorbed and has a positive effect on joints.

Marine gelatins - due to their low hydroxyproline content - have less gelling (lubricating) power. Pork or bovine gelatins are definitely better.

Gelatins of the sea - due to their low hydroxyproline content - have less gelling power (lubrication).
