FOR THE WOMAN WITH SUBSTANCE
THE ROUTINE BUILDER
✓ 89% of Routine types consistently drink Colleins within 7 days
You get up at 6:30 a.m. First, a big glass of water, then you make coffee while your dog lies impatiently by the door. You don’t have “good days” and “bad days”—you have routines that work. For you, consistency isn’t a chore; it’s a form of freedom. The less you have to think about the little things, the more room you have for the big things. And that’s exactly where Colleins fits in. Not as yet another item on your to-do list, but as those 30 seconds between coffee and walking the dog when you do something good for yourself—no fuss, no pills, no hesitation. One scoop in your glass of water. Stir. Drink. Done.
"I'm terrible at sticking with things—except for this. It just fits so naturally into my morning that I never have to think about it. After three months, it really feels like a part of me."
— Linde, 34, Utrecht

FOR THE WOMAN WHO INVESTS IN HER SKIN
THE BEAUTY PERFORMER
✓ Visible improvement in skin for 78% of users within 6 weeks
You have a morning and evening skincare routine. You know the difference between niacinamide and hyaluronic acid. You’re already investing in high-quality serums, regular facials, and products you choose because they work—not because they’re trendy. But you also know this: healthy-looking skin starts from the inside out. You can slather on as much serum as you want—if your collagen production is lagging, you’ll see it in the mirror when you’re 35, 40, or 45. Colleins is what supports that from the inside. 10 grams of marine collagen per day, with vitamin C for optimal absorption. Not a replacement for your skincare routine—a supplement that enhances the work of your serums. You’ll start to see the difference around weeks 4–6. Your skin will feel plumper. Your nails will break less easily. Your hair will feel stronger. It’s not magic—just biology at work.
"I'm skeptical of everything I use—I've seen too many marketing claims in my line of work. But with Colleins, I can really see a difference in my skin. My glow is back, and my nails aren't brittle anymore. No filters, just real results."
— Eva, 41, Antwerp

FOR THE WOMAN WHO WORKS OUT
THE POWER OF WOMEN
✓ On average, 32% faster recovery after exercise
You work out 3 or 4 times a week. Maybe at the gym, maybe at home with resistance bands, maybe running or doing Pilates. It doesn’t matter how—what matters is that you do it, week in and week out. And somewhere along the way, you’ve come to realize that creatine isn’t just a “men’s supplement.” It’s one of the most researched supplements in the world, and it works just as well for women—for recovery, for energy during a workout, for muscle maintenance as you age. But many “creatine for women” products are either too sweet, full of fillers, or sold by brands you don’t trust. That’s why Colleins is made differently: 3 grams of pure creatine, combined with collagen and vitamin C, in a daily drink mix that fits into your morning routine. One product, three ingredients that work together. No separate jars, no capsules, no aftertaste. Just something you drink every morning because you feel your body is asking for it.
"I've been doing CrossFit for years and have tried a lot of supplements. Since I started using Colleins, I've been recovering much faster after tough workouts—less muscle soreness the next day, and more energy between workouts. For me, this is now a staple."
— Naomi, 29, Amsterdam

FOR THE WOMAN WHO LOOKS TO THE LONG TERM
THE STAGES OF A WOMAN'S LIFE
✓ 91% of women aged 45 and older experience stronger hair within 8 weeks
You’re 45, 52, or maybe even 60+. And you’ve noticed that your body is asking a little more of you than it did ten years ago. Your joints are a bit more sensitive. Your skin has lost some of its luster. It takes longer to recover after a busy week. Your hair feels thinner. None of this is dramatic. But you can feel it. And you also know: this isn’t just a phase; this is your new baseline—unless you choose to do something about it. You’re the generation that no longer accepts that “getting older” means “feeling less.” You invest in your body just as you invest in your relationships, your work, your free time. Consciously. For the long term. Not for Instagram, but for yourself. Colleins fits into that way of thinking. No quick fix. No miracle cure. Instead: three ingredients scientifically proven to support skin, hair, joints, and muscle maintenance—especially when you’re at this stage of life. One scoop a day. For you. Because you deserve it.
"At 56, I feel stronger and more energetic than I did at 45. My hair is thicker, my nails are strong, and even my physical therapist noticed that my joints feel more flexible. I wish I had started 10 years earlier."
— Marleen, 56, The Hague

Three proven ingredients. Formulated specifically for women.
Nothing more, nothing less. No fillers, no artificial additives.
6 g Collagen Peptides
Types I and III, derived from bovine sources. Hydrolyzed, meaning broken down into smaller peptides that dissolve easily. Collagen is a protein that occurs naturally in the skin, hair, nails, and connective tissue.
3g Creatine Monohydrate
The most researched form of creatine in the world. Boosts physical performance during repeated short bursts of high-intensity exercise. Works great for your squats, lunges, and hip thrusts. And no, it won’t make you bulky.
80 mg Vitamin C
100% of your daily value. Vitamin C supports normal collagen formation in the skin and helps reduce fatigue.
Claims in accordance with EU Regulation 432/2012. Full list of ingredients and nutritional information on the back of the pouch.
The role of collagen in your body
Collagen is the most abundant protein in your body. It’s found in your skin, hair, nails, joints, and connective tissue. Your body produces it on its own, using amino acids from your diet as building blocks.
Until you turn 25, your body produces more than enough collagen. After that, collagen production gradually decreases each year, by about 1% annually.
By the time you’re 40, you still have about 60% of your original collagen production. By the time you’re 50, that’s less than half. Your body still produces collagen, just not as much as before.
👉 The collagen peptides and amino acids you get from food and supplements provide your body with the building blocks it needs to produce collagen on its own. Vitamin C is essential for this process: it contributes to normal collagen formation in the skin. That’s why it’s intentionally included alongside the collagen in every scoop of Colleins™.
One scoop provides 6 g of Peptan® collagen plus 80 mg of vitamin C. This is the same combination that research consistently identifies as the most effective.
The role of creatine in your body
Creatine is a naturally occurring substance found primarily in your muscles. Your body produces about 1 gram per day in the liver, kidneys, and pancreas. The rest comes from your diet, especially meat and fish. An average diet provides an additional 1 to 2 grams per day.
Women naturally have 70 to 80% of the creatine stores that men have. This is due to both lower muscle mass and lower dietary intake. Research shows that, for this very reason, women often benefit greatly from supplementation.
Creatine enhances physical performance during repeated short bursts of high-intensity exercise. That is its officially recognized effect in the EU, backed by hundreds of studies. In plain language: your squats will feel a little easier, your lunges a little stronger, and your hip thrusts just a bit more effective. Even for those who don’t exercise, it supports your daily physical performance.
👉 According to research, the effective dose is 3 grams per day. That’s exactly what’s in one scoop of Colleins™. No more, no less. And no, it won’t make you bulky. That comes from training and calories, not from creatine.

Frequently Asked Questions
The honest truth: it works for those who stick with it for 30+ days. Not for those who try it for 4 days and then stop. Vitamin C contributes to normal collagen formation in the skin and helps reduce fatigue. Creatine enhances physical performance during successive short, high-intensity efforts. Our customers find that consistent use makes a difference after 3 to 4 weeks, especially since they’re finally sticking with their supplements. The biggest reason it works: you actually drink it every day, because it tastes like Pink Lemonade.
It’s not bland—quite the opposite. Colleins™ has a Pink Lemonade flavor: fresh, slightly sweet, with subtle notes of citrus and berries. We deliberately made it not too sweet and definitely not artificial. Before we launched, we had over 50 women taste our formula. Their feedback shaped the final version. It takes just 15 seconds to mix in cold water. No clumps, no gritty texture. For a richer flavor, use 300 ml of water; for a lighter flavor, use 500 ml.
Mix one scoop with 300 to 500 ml of cold water. Shake or stir for 15 seconds until completely dissolved. Drink it in the morning as a wake-up drink or right before your workout, whichever fits best into your routine. It contains no caffeine, so it’s also fine to drink later in the day. One scoop a day is enough, even on rest days. Consistency is more important than timing.
Yes. Colleins™ is manufactured in the Netherlands in accordance with the strictest European quality standards (GMP and HACCP). Each batch is independently tested by Eurofins, one of the most recognized laboratories in Europe. The ingredients are all safe for daily use at the recommended dosage. Our formula contains no unnecessary fillers, no caffeine, and no stimulants. If you are pregnant or breastfeeding, we recommend consulting your doctor or midwife first.
You'll get your money back. Just send an email to support@colleins.com within 30 days, including your order number and the word "Guarantee" in the subject line. Our team will respond within 24 hours and take care of it. No fine print, no hassle. You don't even have to send the pouch back.
