The unique power of TriSignal Collagen: bioactive tripeptides

Tripeptides are the smallest and most bioactive form of collagen. Your body absorbs them directly: with no detour and no loss. They end up exactly where collagen is needed: in your skin, joints and hair.

  • 99% absorption into the blood

Conventional collagen: ± 40%

  • Detectable in the blood after just 15 minutes

Works faster than any other form of collagen

  • No breakdown process needed

Your body can use the peptides directly

What does this mean for you?
More collagen exactly where you can feel and see it: in the form of firmer skin, suppler joints and fuller hair.

Tripeptides supply collagen – and at the same time activate your own production

✓ Tripeptides supply your body with collagen and at the same time signal it to produce more of its own.

✓ Tripeptides bind directly to the receptor of the skin cell and activate the body's own production there.

✓ Double effect: collagen from outside plus new collagen from your own cells.

✓ No other type of collagen can do this. Only tripeptides work on both levels at once, which is what makes them so unique.

The body's own hyaluronic acid

3.8x more production (clinically proven)

  • 3.8x Stimulates the body's own production of hyaluronic acid by a factor of 3.8 thanks to bioactive tripeptides.
  • Less powder, same effectiveness
  • GLOW25 COLLAGEN INTENSIVE
    2.5 g is enough for a full effect
  • Thanks to the TriSignal Collagen Effect® , the tripeptides are so bioactive that one sixth of the usual amount is already enough.
What this means for you in practice:
  • 1 small sachet, fits in any handbag
  • Dissolves in coffee, tea or water
  • No big tub of powder, so no hassle

Hi, I'm Lea – Brand Director at Glow25®

I'd love to show you how our collagen helps you feel radiant, strong and beautiful again, just like in your best years.

Like many women over 40, I noticed my body starting to change — often subtly, but clearly noticeable.


  • My skin lost its firmness and had less radiance
  • My joints felt stiffer, especially in the morning
  • My hair became thinner and less full


I went looking for a way to support my body from within, so that I could feel strong, energetic and confident again.

Why collagen really works

1. Collagen is a protein that your body produces naturally. It forms the foundation, so to speak, that gives your skin, hair, nails and joints their firmness and suppleness.

2. Until you are 25, your body produces enough collagen. After that, production slowly declines every year.

3. By 40, you have only about 60% of your original collagen. By 50, it's less than half. In other words: the foundations of your skin keep getting weaker.

➜ By taking collagen, you give your body back the building blocks it has lost over the years. This helps counteract natural breakdown and firm your skin from within.

Is collagen really effective or just a marketing promise?

More than 37 studies by renowned scientists have investigated the effects of collagen and clinically proven them.

➜ Proksch: Study with 69 women – after just 4 weeks their skin was visibly firmer. (Skin Pharmacology and Physiology)

➜ Inoue: Study with 72 women around the age of 50 – after 12 weeks their skin was better hydrated and wrinkles were reduced. (Journal of Cosmetic Dermatology)

➜ De Luca: Study with 120 participants – after 90 days wrinkles were visibly reduced and overall skin structure improved. (Journal of Drugs in Dermatology)

These studies show that collagen is more than just a promise. It supports your skin, hair, nails and joints in a measurable way.

Dr. Runnebaum answers your questions about Collagen Intensive

What results can I expect?

Based on all available studies, users reported the following results:

  • After 15 minutes: The tripeptides are detectable in your blood and begin to build collagen.
  • 4 to 6 weeks: First reduction in fine lines and improved skin hydration.
  • 8 to 16 weeks: Visible and noticeable deep-acting effects in skin, hair, nails and joints.
  • After 3 to 6 months: This is where most of the compliments begin, along with the greatest joy over newfound mobility.


Tip: For maximum results we recommend ordering the 3-month pack. Thanks to the 60-day money-back guarantee, you have plenty of time to test the product risk-free. Don't like it? Then you get your money back.

How does Collagen Intensive differ from Glow25 Collagen or Collagen Plus?

Although the original Glow25 Collagen Powder formulas are very effective, Collagen Intensive is a breakthrough in absorption and effectiveness thanks to modern tripeptide technology.

The tiny tripeptides are so small (under 500 Dalton) that they are detectable in your bloodstream just 15 minutes after intake. That means faster, deeper-acting results with even simpler use (just 2,5 g per stick per day, at home or on the go).


This makes Collagen Intensive the most powerful product in the Glow25 range.

Does Collagen Intensive also work in my morning coffee?

Yes! Glow25 spent months fine-tuning the formula to make sure the active ingredients stay effective in hot drinks. The tripeptides in Collagen Intensive are stable up to 90°C, which makes them perfect for your morning coffee ritual.

What is the best way to take Collagen Intensive every day?

Open one stick daily and add it to your favourite drink. The powder is neutral in taste and dissolves quickly and easily in liquids. Most customers prefer to mix their daily dose of collagen powder into:

  • coffee or tea
  • water
  • juices
  • smoothies
  • soups, dressings, yoghurt or quark

There are no proven side effects, is that right?

No systematically known side effects have been found in the available studies or in our own tests. During production, the product undergoes strict safety and quality controls and is therefore well tolerated.

Of course, everyone is different. Some people feel unwell after eating certain foods or supplements. That is as true of apples, bananas, wholemeal bread or broccoli as it is of magnesium, vitamin D or anything else.

That is why we ask you to listen to your body. If, against expectations, you don't feel quite right with daily use, you can use the guarantee and get the full product price back.

Please note: As with all food supplements, we recommend consulting your doctor if you have specific health concerns. This also applies during pregnancy.

What if I'm already seeing good results with my current collagen routine?

Collagen Intensive is designed to strengthen and speed up your current results. Imagine switching from a good torch to a powerful spotlight: everything you already value about your routine simply becomes brighter and stronger.

Is this product suitable for vegetarians/vegans?

Collagen Intensive contains collagen peptides from fish and is therefore suitable for pescatarians, but not for vegetarians or vegans. It is free from:

  • dairy
  • gluten
  • added sugars
  • artificial colours or flavourings
  • genetically modified organisms (GMOs)

How does the satisfaction guarantee work?

You run 0% risk with our 60-day money-back guarantee on all bundles.

Whether you choose the 30-day, 2-month or 3-month pack, you can test Glow25 for 60 days. Not convinced by the product? Then the Glow25 team will refund the full purchase price quickly and without fuss.

Glow25 stands for quality, effectiveness and trust.
