Are you starting to feel stiffer and weaker, and noticing more fine lines as you get older?
From around the age of 25, your body gradually begins to contain less collagen. As you age, this decline may increase further (much like the loss of muscle mass), even if you eat healthily and exercise regularly.
As a result, you may notice that you have less strength and energy, while fine lines become more visible and your skin loses some of its firmness and elasticity.
Around the age of 40, your body needs more than just a healthy diet to combat collagen loss
Your body needs the right nutrients to counteract the breakdown of collagen...
And to support and rebuild the strength of your joints and the elasticity of your skin, so that you can reduce the visible signs of aging and regain your strength, energy, and youthful appearance before it's too late...
Colleins is the ONLY Dutch supplement that combines 6g of collagen peptides, 3g of creatine monohydrate, and 100% of your daily vitamin C in one scoop, in a Pink Lemonade flavor that customers rate an 8.5 on average.
So that in your 40s, 50s, and 60s, you can look and feel just as radiant, pain-free, confident, youthful, and strong as you did in the best years of your life.

How women supported their bodies before complicated routines, separate jars, and endless supplements
In the past, collagen was just a part of our diet
Collagen-rich foods were much more common on the table in the past. Think of broths, bones, and connective tissue. Nowadays, we eat much less of these, even though your body produces less collagen itself as you get older.
Our view on aging has changed completely
Instead of supporting our bodies from within, we have become increasingly accustomed to solutions for what we see on the outside. Creams for fine lines, treatments for firmer skin, and endless products that promise to hide the signs of aging. But aging beautifully and strongly is about more than what you see in the mirror. It is also about what your body needs every day to continue supporting itself.
That is why we made Colleins different
We brought it back to one simple daily routine:
6g collagen peptides, 3g creatine, and 80mg vitamin C
in one scoop. Pink Lemonade, add water, shake, and you're done. No three separate jars. Just one routine that is easy to stick to.
Ready in 15 seconds
1. Scoop
Add one scoop of Colleins to a glass of water or your smoothie. One bag is enough for 30 days, so no more measuring or loose jars.
2. Shake
Stir or shake briefly until everything is dissolved. Colleins mixes easily, without lumps, and smells and tastes fresh.
3. Drink
Drink it up and get on with your day. One refreshing moment that replaces your loose supplements — easy to take to the gym, work, or while traveling.
What We Believe
The best supplement is the one you actually take every day.
Let's be honest: most collagen powders don't taste good. If you've tried other brands, you probably know the drill. You buy something, you take it faithfully for two weeks, and then it starts to grate on you. The taste. The clumping. The fact that you have to keep two other jars next to it. After a month, it ends up at the back of the cupboard and you've basically just wasted your money.
That is what we built Colleins on. Not on a longer list of ingredients, but on the question of whether you would still be drinking it in three months' time.
One scoop per day: 6 g collagen peptides, 3 g creatine monohydrate and 80 mg vitamin C. In a Pink Lemonade that 95% of our customers rate a 7 or higher.

Real reviews from women 40+ about Colleins
Frequently Asked Questions
One scoop per day in 300 to 500 ml of cold water. Shake or stir until the powder is completely dissolved.
For a fuller taste, use 300 ml; for a fresher taste, use 500 ml. We recommend cold water: that is what the Pink Lemonade flavor was made for.
Tip from our reviews: put the powder in the bottle first and then the water. Customers who do it the other way around are more likely to have powder left at the bottom. A milk frother also works well if you want to mix it extra thoroughly.
Colleins is a lemonade flavor, so it doesn't combine as well with hot milk or coffee as a chocolate flavor does. If you are making a smoothie, it works just fine.
When: take it at a time you will return to every day. Most customers do it in the morning, some just before working out. With or without food doesn't matter.
There is no best time. Colleins contains no caffeine or other stimulants, so you can take it in the morning, afternoon, or evening without it affecting your sleep.
What does matter is consistency. Choose one time and stick to it. Most customers link it to something they already do: next to the kettle, after brushing their teeth, before heading out the door.
Per 10-gram scoop:
- 6 g bovine collagen peptides (type I), of which at least 90% protein
- 3 g creatine monohydrate
- 80 mg vitamin C, 100% of the daily reference intake
Otherwise, only what is necessary for flavor and texture: flavorings (raspberry, strawberry, lemon), citric acid as an acidity regulator, beetroot powder for color, and a small amount of sucralose as a sweetener. No fillers, no artificial colors, no significant sugar.
Vitamin C contributes to normal collagen formation for the normal function of the skin and to the reduction of tiredness and fatigue. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise.
Colleins is produced in the Netherlands under HACCP standards, is Halal certified, and is sent to Eurofins per batch for independent verification.
Are you pregnant or breastfeeding, taking medication, or under medical supervision? Please consult your doctor first. Contains bovine. Not suitable for vegetarians and vegans.
A bag contains 300 grams of powder. With one 10-gram scoop per day, it will last you 30 days.
Important: the included scoop can hold more than 10 grams if you heap it. Use a level scoop; this will result in a dosage of approximately 10 grams and ensure the bag lasts a full month.
Pink Lemonade: fresh, lightly sweet, with citrus and a fruity hint of raspberry and strawberry. Intentionally not too sweet and without the chemical aftertaste that many supplements have.
Our customers rate the flavor an 8.5 on average, and 95% give it a 7 or higher (n=194). This is the most mentioned point in reviews, usually in the form of "finally, a collagen that actually tastes good."
Find it too strong? Use more water, up to 500 ml. Find it too light? Go down to 300 ml.
Colleins is a dietary supplement for adult women and contains no hormones, herbal extracts, caffeine, or other stimulants. It is not a remedy for menopausal symptoms, nor do we present it as such.
What we can say: it is a daily supplement with collagen peptides, creatine, and vitamin C, and it is suitable for daily use in all life stages from age 18. Many of our customers are women between 40 and 65.
If you have specific health issues or are taking medication, please discuss this with your GP.
Colleins is a dietary supplement, not a medicine. The ingredients are safe for daily use at the recommended dosage.
If you are taking medication, have a medical condition, or are under medical supervision, please consult your doctor before starting. This applies to every supplement and is not specific to Colleins.
In case of side effects: stop use and contact your doctor. Please also let us know at support@colleins.com so we can find a solution together.
Honest answer: Colleins is not a remedy that repairs anything in your body. It is a way to get three nutrients every day without any effort.
What the ingredients do:
Creatine is one of the most researched supplements in the world. Creatine increases physical performance during successive short, high-intensity exercises. Your body produces it itself and you get it through meat and fish, but the daily amount from food is limited.
Vitamin C contributes to normal collagen formation for the normal functioning of the skin, and to the reduction of tiredness and fatigue.
Collagen peptides are a protein that occurs naturally in skin, hair, nails, and connective tissue. We do not make health claims about collagen, because they have not been approved in Europe. Brands that do so, do it without permission.
What works is consistency. With supplements, it is not about the first week but about the hundredth day.
No. Colleins does not contain any of the fourteen legally designated allergens: no gluten, dairy, soy, egg, nuts, peanuts, fish, crustaceans or molluscs, celery, mustard, sesame, lupin, or sulphite.
It does contain beef (bovine-sourced collagen) and is therefore not suitable for vegetarians and vegans.
Colleins is not genetically modified.
Collagen naturally consists of long protein chains. During hydrolysis, these chains are cut into smaller pieces called peptides.
For you, this primarily means two practical things: it dissolves in cold water instead of floating on top, and it lacks the typical smell and texture of unprocessed collagen. That is why Colleins drinks as easily as lemonade.
Our collagen peptides are bovine-sourced (type I). Colleins is produced in the Netherlands by a Dutch manufacturer.
Every batch is independently tested by Eurofins for, among other things, heavy metals (arsenic, cadmium, mercury, lead) and microbiology. The test report for your batch can be requested via support@colleins.com, using the batch number at the bottom right on the back of your bag.
We are not allowed to claim that, and therefore we do not.
There are no approved health claims for collagen in Europe, not even for joints. For creatine, there is one approved claim regarding physical performance during short, high-intensity exercise, and one regarding muscle strength in combination with resistance training for adults over 55.
You can read what customers experience themselves in our reviews. Those are personal experiences, not promises from us.
Colleins is nutrition, not medicine, and can be combined with most supplements. Think of multivitamins, omega-3, magnesium, or vitamin D.
Pay attention to your total vitamin C intake: Colleins already provides 100% of your daily reference intake. If you also take a vitamin C supplement, your intake will exceed this.
If you are taking medication, consult your doctor or pharmacist before adding a new supplement.

Questions about your order? support@colleins.com or +31 70 2042685. We usually respond within one business day.
We make no promises about when you will notice results, because we are neither allowed nor able to do so.
What we do know from our reviews: customers who try to form an opinion after a few weeks are usually still waiting to see. Customers who describe their experience after two or three bags are more positive. That says something important about how supplements work: it is a routine, not a cure.
Practical advice: start with 90 days. That is long enough to know if it suits you, and it is the bundle that offers the lowest daily cost.
Day 1. One scoop in 300 to 500 ml of cold water, shake, done. The whole process takes half a minute.
Week 1. You’ve found your spot. Next to the kettle, in your gym bag, by the coffee machine.
Week 4. You don't think about it anymore. This is the point where most supplements fail and where taste makes the difference.
Week 12. You’ve gone through three bags and during that time have taken your 3g of creatine, 6g of collagen peptides, and your full daily dose of vitamin C every day.
What you notice in yourself during that period varies from person to person. We don’t promise you a transformation. We’ve created something that you’ll still be using four months from now.
Email us within 30 days of receipt and you will get your money back. No three-page return form, no questions asked.
If you would like to return your order instead of getting a refund: that is possible within 30 days, provided the packaging is unopened and sealed. Dietary supplements are hygiene products, so an opened bag cannot be returned.
support@colleins.com, with your order number.
Colleins contains virtually no sugar and no significant carbohydrates. We use sucralose as a sweetener, which does not affect your blood sugar levels.
That said: with diabetes, it is about your overall diet and any medication. Therefore, consult your GP, diabetes nurse, or dietitian before starting. We cannot make that assessment for you.
Yes. In addition to the Netherlands and Belgium, we ship to Germany (1 to 2 business days), the United Kingdom (3 to 5 business days), and the rest of the EU (2 to 6 business days). Shipping rates vary by country and are displayed at checkout.
Three reasons, and none of them are about efficacy:
Everything in one scoop. Collagen, creatine, and vitamin C in one go instead of three separate jars. This is what customers mention most often in reviews after the taste.
The taste. An average of 8.5 in our customer survey. With supplements, taste is not a luxury but the reason you'll still be taking it in three months.
Independent verification. Every batch goes to Eurofins. Test reports are available upon request. Most brands cannot say that.
What we do not claim: that Colleins is more effective than other collagen products. No one can substantiate that comparison, and neither can we.
Collagen peptides (bovine), creatine monohydrate, flavorings (raspberry, strawberry, lemon), acidity regulator (citric acid), vitamin C (ascorbic acid), beetroot powder, sweetener (sucralose).
Per 10-gram serving: 6000 mg collagen peptides (type I, bovine), 3000 mg creatine monohydrate, 80 mg vitamin C (100% RI).
Storage: keep sealed, between 15 and 25 degrees, away from direct sunlight. Shelf life 24 months after production.
Usage: one scoop (approximately 10 g) per day in 300 ml of water. Do not exceed the recommended daily amount.
Food supplements are not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of young children. Do not use if the seal is broken.
