Skin is softer, the skin barrier stronger.

I take it past 50 — skin finally responds. After sachets just mildly, NANO more.
Yvona
I recommend it to all the girls around me.

It works 👍
Martina
Second order. Firmer skin, less-pronounced lines around the eyes after 6 weeks.
Petra
After 6 weeks the skin is visibly better, less dryness.
Eliška
Works, but the taste isn't for everyone. I don't mind, my daughter pulls faces. A rinse with water and it's fine.
Eliška
Great satisfaction. After three months my skin is fresher, lines around the eyes less visible. Worth it.

After a month, shinier hair and a stronger skin barrier. Recommended.
Tatiana
I take it in winter as immune support too. Proper vitamin C 👌

I recommend it to all women past 30. Start sooner rather than later. The skin needs to build collagen reserves.

After menopause the skin needs help. This works, unlike many pricey serums.

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).
