Finally a product without sweeteners. With a glass of water in the morning before coffee.
Pavlína
I've been taking collalloc for three months — joints hurt less after running. My wife sees the skin, I see the knees. Both happy.
Michal
The sachet smells great, no chemical flavour 👍
Magda
Nice packaging.
Leoš
Three months in and my skin is visibly firmer. My beautician recommended it; I'll be back for more.
Romana
I recommend it to everyone.
Martin
Nice packaging.
Aneta
I've been taking it for a year and a half. When I ran out and skipped a month, my skin told me immediately. I always come back.

Petr
Very happy 😊
Adéla
Been taking it a year — strong nails, thicker hair. The price covers the result.
Helena
The dropper format is brilliant. Under the tongue, let it work for a minute, rinse with water. No mixing, ideal for travel.

Diana
Yes, I recommend it.
Tereza

👌👌
Jana
Past 50 I'm careful what I buy. This passed the bar, and so did it for my 30-year-old daughter. We both take it.
Drahomíra
Hair stopped falling out the way it used to. I take it with 100 mg vitamin C — I recommend the combo.
Klára
Satisfied
Věra
Flawless 👍

After two years of use I see a dramatic difference. According to friends my skin looks five years younger. Worth it.

I take it regularly.
Aleksandra
It works.
Zuzana
After two months, visibly better skin. I take it in the morning before breakfast.
Ivana
I take it past 50 — skin finally responds. After sachets just mildly, NANO more.
Yvona
Skin noticeably better after the second month, especially around the eyes. I used to try creams — collagen is another league.
Andrea
Works, but the effect only came after 2 months.
Jan
Top product.
Marianna
🙌
Klára
A complement to the sachets, not a replacement. Different moments, both formats work for me.
Markéta
Works as it should. A bit sour straight up, so I always mix with collagen or into juice.
Olena
Good collagen

Veronika
I've been using the product for a week, so I can't judge yet.
Štěpánka
I'm on my second pack.
Simona
After a month, shinier hair and a stronger skin barrier. Recommended.

Second month, small change on the skin so far. I hope it shows up after 60 days.

Nails don't break, hair is thicker.

Science, not wellness
Skin starts forgetting at 25. Collagen reminds it.
Two worlds of collalloc
Bioactive marine collagen
Standard collagen is 5 to 10 kDa. The 500 Da peptide passes the gut wall and reaches the bloodstream.
Bioactive peptides for skin, hair, and nails. No fillers, no shortcuts.
Wild fish from the Arctic Ocean. Processed for us in Switzerland.
Functional mushrooms
Lion’s Mane, Cordyceps, Chaga, Maitake, each with its own job.
2,400 mg of active compounds per day. 4 capsules, 30 days per pack.
Energy and clarity without the energy-drink effect. Anytime in your day.
The most common questions about our products, production and brand. Concrete answers, no marketing fluff.
collalloc kolagen is 100% bioactive marine collagen with a molecular weight around 500 Daltons, hydrolysed using Swiss TRIPEPTIDE® technology, with a clinically measured 95% absorption. One daily dose contains 3,300 mg of pure collagen of types I, II and III, with no fillers, sweeteners, colourings or flavourings. Bioactive means the body works with it the way it works with its own collagen.
collalloc is made from off-cuts of wild-caught North Atlantic fish, specifically the parts (skin, fins, heads) the food industry would otherwise discard. Hydrolysis is done in Switzerland; sachet filling on our own lines in Brno (Czech Republic). No fish are caught extra for the collagen, the process is ethical upcycling. More on our production page.
Bovine, porcine and chicken collagen need heat treatment before processing, which drops absorption to around 10%. Marine collagen from fish does not require heat treatment, stays bioactive, and the body can take it up far more efficiently. Bovine collagen also carries an environmental cost, since most of it comes from Brazil.
First visible changes with collalloc kolagen typically appear after 4 to 6 weeks of daily use, mainly on skin, hair and nails. For the full effect we recommend a continuous course of 60 to 90 days. The musculoskeletal system responds individually and may take longer. Three boxes is a reasonable trial period.
collalloc is a 100% natural bioactive marine collagen with no additives, and many customers take it during pregnancy and nursing with positive feedback. During pregnancy we recommend consulting a doctor. During nursing the product is safe to take.
collalloc is not vegan and cannot be, because its source is wild-caught marine fish. Vegan collagen does not exist as such; all collagen is animal-derived. There are plant-based supports for collagen synthesis (vitamin C, for example), but a true plant collagen is not possible.
collalloc is a 100% natural marine collagen without additives, sweeteners, colourings or flavourings. It does not contain sugar, gluten, lactose or GMO. It is, however, a fish product, so it is not suitable for people with a fish allergy.
No, collalloc does not need refrigeration, neither the sachets nor the liquid collalloc NANO 2.0. The ideal storage temperature is between 4 and 24 °C, in a dry place out of direct sunlight. The box is fine on a kitchen counter or in a cosmetics bag.
collalloc MIND is a food supplement with four functional mushrooms in capsules, made for people who want to look after their mind, energy and calm. It contains Lion’s Mane (memory, focus), Cordyceps (caffeine-free energy), Chaga (antioxidant) and Maitake (stress, hormonal balance), 600 mg of each per dose, 120 capsules for 30 days.
Yes, collalloc MIND can be taken with coffee without any issue. It is caffeine-free and works neither against nor with coffee, it is not a stimulant. The mushrooms act cumulatively; the full effect arrives after 3 to 4 weeks of daily use.
collalloc is available direct from collalloc.com and through our retail partners: Lekárna.cz, Notino, Alza and Benu. collalloc kolagen costs €24 for 30 sachets (one month of use), collalloc MIND €32 for 120 capsules (one month of use).
collalloc is run by the Czech company opio a.s., based in Brno (Dukelská třída 1562/57d, 614 00 Brno, VAT ID CZ10982230), founded in 2016 by Záviš Lacina (more on the about us page). Raw material is hydrolysed in Switzerland; sachets are filled on our own lines in the Czech Republic, and boxes are assembled together with Finish Work, a cooperative for people with disabilities (more on the production page).
