Collagen types I, II and III differ in their location and function in your body. Type I is mainly found in your skin, bones and tendons and provides strength. Type II is found specifically in cartilage and joints. Type III works together with type I in blood vessels, organs and skin for elasticity. Each type has unique benefits for different aspects of your health.
What does collagen actually do in your body?
Collagen is the most abundant protein in your body and acts as a kind of glue that holds everything together. It forms strong fibres that give structure to your skin, bones, muscles, tendons and blood vessels. You can compare it to the steel beams in a building - without collagen, your body would literally fall apart.
Your body makes collagen by combining amino acids, especially glycine, proline and hydroxyproline. This process happens continuously, but slows down as you get older. From the age of 25, collagen production decreases by about 1% every year. This is why you get wrinkles, your joints get stiffer and wounds heal more slowly.
The interesting thing is that not all collagen is the same. Your body needs different types for different tasks. Type I provides strength, type II keeps your joints flexible, and type III gives elasticity. They work together as a team to keep your body healthy and functional.
Where can you find collagen type I and what does it do for you?
Collagen type I is by far the most abundant type in your body, making up about 90% of all your collagen. You find it mostly in your skin, bones, tendons, ligaments and the connective tissue of your organs. This type provides strength and tensile strength - Think of the strength you need to jump or lift a heavy bag.
For your skin, type I is essential because it provides the structure that fights wrinkles and keeps your skin taut. In your bones, it works with minerals like calcium to give strength. Without sufficient type I collagen, your bones become brittle and fragile.
This explains why type I is so popular in supplements. Many people notice that their skin becomes smoother and their nails stronger. It also helps recovery after sports because your tendons and ligaments are mainly made up of type I. If you are looking for general anti-ageing benefits, type I is often the best choice.
How does collagen type II work differently from the other types?
Collagen type II is highly specialised and is found almost exclusively in your cartilage. While types I and III mainly provide strength and elasticity, type II has a unique structure that is shock absorption and flexibility enables. It forms a network that retains water, making your cartilage act like a sponge.
The big difference is in the way the collagen fibres are structured. Type II has a more open structure that leaves room for other substances such as glucosamine and chondroitin sulphate. This combination allows your joints to move smoothly and absorb blows.
You should consider Type II if you suffer from stiff joints, cracking pain when moving, or if you do a lot of sports that put a lot of strain on your joints. It works differently from painkillers because it actually helps maintain and repair cartilage. Many people notice their joints feel smoother after a few weeks of use.
What role does collagen type III play in your body?
Collagen type III acts as the elastic partner of type I, providing flexibility and elasticity in your tissues. You find it mostly in your blood vessels, intestines, uterus, and in the deeper layers of your skin. It allows structures to stretch and return to their original shape.
In your skin, type III works closely with type I. Whereas type I provides firmness, type III allows your skin to move with you when you smile, frown or make other facial expressions. It also helps with wound healing by quickly forming a flexible network on which new cells can grow.
For your blood vessels, type III is important because it allows them to expand and contract with changes in blood pressure. This type decreases with age, which explains why older skin becomes less elastic. This is why you often find type III combined with type I in anti-ageing supplements - they complement each other perfectly.
Which type of collagen best suits your goals?
Choosing the right collagen type depends on what you want to achieve. For general skin health and anti-ageing a combination of types I and III is most effective. If you mainly suffer from joint problems or do a lot of sports, type II is the better choice.
For best results, you can also combine different types. Many people use type I and III for their skin during the day, and take type II separately for their joints. Your body can keep them well apart and direct them to the right places.
When choosing a collagen supplement on the form in which it is presented. Hydrolysed collagen is better absorbed than whole proteins. Preferably take it on an empty stomach with some vitamin C, which helps with absorption.

Frequently Asked Questions
How long does it take to see results from collagen supplements?
De meeste mensen beginnen na 4-6 weken de eerste voordelen te merken, zoals stevigere nagels en soepelere huid. Voor merkbare verbeteringen in gewrichten kan het 8-12 weken duren. Consistentie is belangrijk – neem je supplement dagelijks op hetzelfde tijdstip voor de beste resultaten.
Can I take different collagen types at the same time?
Ja, dat is zelfs aan te raden voor optimale voordelen. Je lichaam kan verschillende types goed uit elkaar houden en naar de juiste weefsels sturen. Veel mensen combineren type I en III ’s ochtends voor huidvoordelen, en nemen type II apart in voor gewrichtsondersteuning.
What dosage of collagen do you need for noticeable effects?
For skin benefits, 2.5-5 grams per day is usually sufficient, while for joint support, 8-10 grams of type II collagen is recommended. Start with a lower dose and build up slowly to let your stomach get used to the supplement.
What are the most common mistakes when using collagen?
De grootste fout is inconsistent gebruik – collageen werkt alleen bij dagelijkse inname. Ook nemen veel mensen het samen met koffie, wat de opname kan verminderen. Neem het liever op een lege maag met water en wat vitamine C voor optimale absorptie.
Is there a difference between collagen from different sources such as beef, fish or chicken?
Yes, the source makes a difference to the composition. Bovine collagen contains mainly types I and III, perfect for skin and bones. Chicken collagen is rich in type II for joints. Viscollagen is absorbed fastest but contains mainly type I.
Can vegetarians and vegans also supplement their collagen?
Real collagen only comes from animal sources, but vegetarians can use collagen boosters with amino acids such as glycine, proline and vitamin C. These help your body make more of its own collagen, although this does not work as directly as animal collagen.
When should you stop taking collagen supplements?
Collagen is safe for long-term use and you don't need to stop unless you experience side effects. However, you can take a 2-week break after 3 months to assess whether you are still experiencing benefits. Note that benefits disappear slowly when you stop.
