Quick answer
collalloc NANO 2.0 is a liquid bioactive marine collagen with vitamin C in a dropper, 30 doses of 1 ml. Squeeze it into your mouth and wash it down, 95% bioavailability thanks to a 500 Da molecular weight and the liquid form. Vitamin C supports the body’s own collagen synthesis. No flavourings or preservatives. €28.
Science, not wellness
Liquid form, no mixing
A sachet has to be stirred into water first; the liquid form skips that: squeeze the dropper into your mouth and wash it down, done. The 95% absorption is not some trick in the mouth, but the low molecular weight around 500 Daltons and the liquid form, which let the peptides absorb easily in the gut. The vitamin C in every dose acts as the cofactor without which the body cannot start synthesising its own collagen.
How we know
- Iwai K. et al. Identification of food-derived collagen peptides in human blood after oral ingestion of gelatin hydrolysates. Journal of Agricultural and Food Chemistry, 2005. doi.org/10.1021/jf050206p
- Oesser S. et al. Oral administration of 14C labeled gelatin hydrolysate leads to an accumulation of radioactivity in cartilage of mice. Journal of Nutrition, 1999. doi.org/10.1093/jn/129.10.1891
These papers describe the mechanism: that ingested collagen peptides appear in the blood and reach connective tissue. They are not the source of the 95% figure, which comes from measurement of our raw material.
Who it suits
Who buys it most often
Past forty, and through menopause
The body’s own collagen production falls with age, and the decline speeds up around menopause. This is the most common reason women start.
Anyone working on hair and nails
Type I makes up most of the collagen in the hair root and the nail bed. Marine collagen is almost entirely type I, so it lands exactly there.
Anyone who loads their body
Running, the gym, long hours on your feet. People who feel the load tend to pick a collagen that contains type II.
Anyone who tried collagen and noticed nothing
The usual reason is not the dose but the size of the molecule. Common hydrolysates run 2,000 to 5,000 Da and only a fraction crosses the gut wall.
Before you choose
Marine or bovine collagen
The most common question before a first purchase. The answer most sites give is “marine absorbs better”. That is a shortcut. Absorption is not decided by the animal, it is decided by how finely the collagen has been broken down.
| Marine | Bovine | |
|---|---|---|
| Source | Fish skin and scales | Cattle hide, bone and cartilage |
| Dominant type | Type I | Type I and III |
| Molecular weight | Depends on hydrolysis; ours is around 500 Da | Depends on hydrolysis; commonly 2,000 to 5,000 Da |
| Not suitable with | A fish allergy | A beef allergy, some religious restrictions |
| Taste | None, when it is pure | None, when it is pure |
The difference in type is real: marine collagen is almost entirely type I, the type that dominates skin, hair and nails. The difference in absorption, though, comes from the hydrolysis rather than the origin. Bovine collagen broken down to tripeptides absorbs just as well as marine collagen of the same size. So look for daltons on the label, not just the word “marine”.
Origin
From sustainable North Sea fishing
Our collagen comes from the skin of wild North Sea fish. Not from fish farms, and not from fish caught for it. It is a by-product of fishing for food: the part of the fish that would otherwise end up as waste becomes a raw material of the highest purity. A source that does not strain fish stocks or the sea.
Effect
A small molecule, a big difference
What matters is not how much collagen you drink, but how much your body absorbs. A molecule around 500 Daltons passes through the gut wall to where the body builds skin, hair and nails, which is why absorption is 95 %, not ten percent like ordinary collagens. And the dose contains no fillers, dyes or sweeteners.

Laboratory tested
What the analyses found
A fish-derived supplement raises two questions that deserve a number rather than a promise: what is in it, and what is not. Here are both.
Heavy metals
The most common worry with marine collagen. An external laboratory runs this every month.
| Parameter | Result |
|---|---|
| MercuryLimit 0.10 mg/kg | Under the limit |
| LeadLimit 3 mg/kg | Under the limit |
| CadmiumLimit 0.5 mg/kg | Under the limit |
| ArsenicLimit 1.0 mg/kg | Under the limit |
Microbiology
| Parameter | Result |
|---|---|

How often it is measured
- Microbiology on every production batch
- Heavy metals by an external laboratory every month
- Molecular weight by an external laboratory once a year
Allergens
No sugar, gluten, lactose or GMO. It is a fish-derived product, so it is not suitable for anyone with a fish allergy.
Storage
At room temperature, out of direct sunlight. Close the bottle firmly after each use. The best-before date is printed on the bottle and on the box.
Warnings
- Keep out of reach of children.
- Do not exceed the recommended daily dose.
- Not a substitute for a varied diet.
- Consult a doctor during pregnancy and breastfeeding.

★★★★★★★★★★I felt the effects after three weeks — skin more hydrated. With vitamin C in one product it's practical.
Eliška✓ Verified buyer
★★★★★★★★★★Works, but the taste isn't for everyone. I don't mind, my daughter pulls faces. A rinse with water and it's fine.

★★★★★★★★★★👍👍
Hana✓ Verified buyer
★★★★★★★★★★Liquid form absorbs faster — you really feel it.
Petra✓ Verified buyer
★★★★★★★★★★Practical but a higher price per dose. For me a bonus product to the sachets, not the main one.
Klára✓ Verified buyer
★★★★★★★★★★Satisfied.
Renata✓ Verified buyer
★★★★★★★★★★First time with a liquid collagen. It works, but the sachets feel more decisive — more collagen per dose.
Iveta✓ Verified buyer
★★★★★★★★★★Vitamin C inside is a plus. Collagen doesn't work without it, so this is an elegant single-formula solution.
Apolena✓ Verified buyer
★★★★★★★★★★Finally a collagen that doesnt cause stomach issues 😊
Romana✓ Verified buyer
★★★★★★★★★★Three months in and my skin is visibly firmer. My beautician recommended it; I'll be back for more.
FAQ
You often ask
How is NANO 2.0 different from the sachet collagen?
Sachets contain 3,300 mg of collagen per dose, NANO 2.0 contains 700 mg in a practical liquid form. NANO is great when you do not want to mix anything, for example while travelling. For a higher daily dose, combine it with the sachets.
How long until I see results?
Customers typically describe subjective changes in the skin after 3 to 4 weeks. For the full effect, combine NANO with the sachet collagen to top up a higher daily dose.
Is one dropper a day enough?
Yes. 1 ml from the dropper into your mouth and wash it down; that completes the daily dose.
Can I take NANO 2.0 any time?
Yes, morning or evening. The liquid form does not depend on food or timing. Consistency matters more than the exact time.
What if it does not suit me?
Return within 30 days, no reason needed. Just email collalloc@collalloc.com.
