After you turn 35, your body produces less collagen every year. This is the one morning routine that over 10,000 women chose to counteract that and get out of bed feeling more energized right away.
"I was already taking collagen. But it wasn't until I switched to something that also boosted my energy and strength that I really noticed a difference. My skin is glowing, and I feel years younger."

1.Do you recognize 3 or more of these signs?
Most women see these as separate issues. But they are signs of the same, silent process: starting at age 35, your body produces less and less collagen, and muscle strength declines more rapidly.
During busy, hectic weeks, your mind can sometimes feel more cluttered and your energy levels lower. Vitamin C helps reduce fatigue and tiredness—a boost that’s especially welcome during those times.
🪞 Your skin feels less firm than it used to
💅 Nails that break or split more easily
💆 Hair that feels thinner
🦵 Less strength in your legs when climbing stairs or doing squats
🔋 Getting tired more quickly, especially during busy weeks
2. Two things disappear at the same time, and most supplements only address one of them
Once you turn 35, something happens that is rarely mentioned in the same breath:
Your collagen levels are declining: The protein that gives your skin, hair, and nails their strength decreases every year. By the time you reach your 40s, a significant amount has already disappeared.
Your muscle strength also declines: Starting in your 30s, you gradually lose muscle mass—a difference you’ll notice when climbing stairs, lifting things, or just getting through the day.
Creams and serums only work on the surface. And a standalone collagen supplement doesn’t boost your strength. That’s why Colleins tackles both—in a single scoop.
3. One scoop. Three proven ingredients. No more separate jars.
6 g Peptan® Collagen Peptides (Types I & III)
We usePEPTAN®, one of the most extensively researched sources of collagen in the world. The collagen is hydrolyzed: the proteins have been broken down into small peptides, allowing the powder to dissolve completely without clumping and making it easy to drink. Collagen is a protein that occurs naturally in the skin, hair, and nails.
3 g creatine monohydrate
The most widely studied supplement in the world, including among women. Creatine enhances physical performance during short, intense bursts of exercise.* This is what sets Colleins apart: strength and beauty.
80 mg vitamin C (100% NRV)
Vitamin C supports normal collagen formation in the skin and helps reduce fatigue.*
4. Why Creatine Won’t Make You Bulky (But It Will Change Your Day)
The biggest myth. Creatine doesn’t make you “bulky”—that comes from intense training and calories, not from 3 grams of powder in your water. What it does do: it supports your physical performance precisely during the years when your strength naturally declines. Other brands don’t offer this—we do.
Other collagen supplements didn't do anything for my energy. Since I started taking Colleins, I feel more energized during my workouts, and my skin really does look more radiant.

5. Finally, a flavor you can look forward to
Let’s be honest: a lot of supplements don’t taste very good. They’re either way too sweet or have a strange aftertaste. In fact, we’ve heard from many customers that they simply couldn’t bring themselves to drink collagen as a supplement.
Colleins has a refreshing pink lemonade flavor that isn't too sweet. Mix it with 300–500 ml of cold water, and you'll have a refreshing drink you'll look forward to every day.
Pink Lemonade is a refreshing, slightly sweet flavor with a distinct citrus base (like lemonade), combined with a soft, fruity twist.
I'll never forget it because it just tastes so good, haha.

6. What to Expect
Weeks 1–2
The ritual is part of your routine. Just shake it up, drink it, and you’re done. Start with 3 g of creatine per day—the amount that boosts physical performance during short, intense workouts.*
Weeks 3–4
Many women find that they can keep going without any trouble. You can work out, lift weights, and hit your step goals with that extra bit of support in your legs and glutes—which is exactly what short, intense workouts require.*
Weeks 6–8
Colleins has become a regular part of your morning. One scoop, every day—the kind of consistency that makes a routine really work for you.
*Creatine improves physical performance during repeated short bursts of high-intensity exercise when taken daily at a dose of 3 g. Individual results may vary.

"It tastes really good! I used to take creatine and Collins' Pink Lemonade powder tastes absolutely amazing. It's the first supplement in my cabinet that doesn't taste like 'chemical powder'! I'll definitely be ordering this more often. Collagen on its own is so gross. This is way better and easier."

One scoop a day is enough. Mix it with 300–500 ml of cold water and drink it in the morning or before your workout, whichever fits your schedule best. For a richer flavor, use a little less water; for a lighter flavor, use a little more. Consistency is more important than timing: it’s all about your daily routine.
