The Kollo Difference
Unlike mass-produced, generic bulk collagen, the Kollo range is built differently - chosen for what your body actually absorbs, not the cheapest raw material available.
Inside Every Sachet
Our Premium Liquid Marine Collagen is independently tested and proudly Informed Choice certified, so it is safe and trusted for everyday use. Free from gluten, dairy, lactose, soy and wheat, making it a reliable choice for a wide range of dietary needs.

Its low molecular weight ensures superior absorption and bioavailability compared to generic collagens, delivering visible, long-lasting results. Each sachet provides 10,000 mg, the optimal research-backed daily dose.

From Our Founder
Hear the story behind our premium liquid marine collagen, and why the team built it the way they did, straight from the people who created it.
Our liquid marine collagen delivers 10,000mg of Naticol® hydrolysed marine collagen peptides in a single daily sachet, with vitamins B and C. That is a full clinical-strength dose, not a fraction of one topped up with fillers. It arrives ready to drink, so there is no measuring, no mixing and no undissolved residue at the bottom of the glass. Over 7,000 reviews and more than 60 industry awards since 2020 sit behind it. Read more on the benefits of liquid marine collagen.
Collagen is the structural protein found throughout skin, hair, nails, joints and bone, and levels decline naturally from our mid-twenties onwards. Our liquid collagen supplement supplies 10,000mg of Type I marine collagen peptides daily, the same dose used in published research on hydrolysed marine collagen.
Each sachet also delivers vitamin C, which contributes to normal collagen formation for the normal function of skin, bones, cartilage and blood vessels, and helps reduce tiredness and fatigue. Take it consistently for eight to twelve weeks. See when to take marine collagen for practical guidance.
Tablets rarely carry a full 10,000mg dose, so you are often swallowing several to reach what one serving gives you. Liquid and powder both deliver the full dose. Our sachets are pre-measured and ready to drink, ideal for travel and busy mornings. Our marine collagen powder uses the identical Naticol® collagen and mixes into whatever you already drink.
Hydrolysed collagen peptides are broken into small fragments the body absorbs efficiently. Because our formula is already in liquid form, there is no undissolved powder and no capsule to break down first, so every sachet delivers the complete 10,000mg dose consistently.
Loved By Thousands
Skin
Game changer
I was delighted and super surprised as I big sceptic of any supplements, that Kollo actually had visible changes to my body and skin. My stomach bloating has gone and around my eyes too. My skin looks rehydrated and supple and young again. I am blown away!
Joints
The best
I have been using Kollo for a while now. I love it, growing my nails out and they are growing really strong and healthy. I have kollo every morning and really think it is worth it. Skin, nails and hair haven’t looked better for a while. So thank you!
Joints
Amazing!
Love my Kollo, noticed improvement in skin, hair, nails and joint health, feel amazing at 61
Skin
Kollo gave me my glow back
I have been using Kollo liquid collagen for a couple of years now, and the results are amazing. I’m about to join the 30 club (eeek) but I honestly think my consistent use of Kollo is definitely one of the reasons I don’t need to rush to the aestheticians for a Botox appointment 😆 I recently took a break from using it during pregnancy and I really noticed a huge difference in my skin and hair. Now I’m taking it again, I feel like I have got my glow back and I just HAVE to shout about this product!!!! It’s a non negotiable in my skincare routine and it’s packed with so many goodies. 11/10 would recommend
Hair
Amazing
I have been taking Kollo for a 3 months, I my hair nail and strength in myself has improved so much. Don't feel as tired, lots of energy. Love it! Would recommend to all my friends 🧡
Skin
This collagen has been a game changer for me!
When I started taking Kollo, I had awful acne, my hair was short because bleach had damaged it, and I had bad fatigue! I have now been taking Kollo for 6 years and it’s honestly made a huge difference! My hair is long and strong (my hairdresser can’t believe how long my hair has grown), my acne has cleared, and I am full of energy! I’d never tried collagen before I got Kollo, and I’m so glad I invested in Kollo! Collagen is vital for all of us over the age of 25! People have even started telling me that I look younger.

The Kollo Standard
Everything You Need To Know
Most customers take it consistently for eight to twelve weeks before reporting a difference, commonly in skin, hair and nails. Collagen is not an overnight product. Daily consistency matters far more than the time of day you take it.
Each sachet contains 10,000mg of Naticol® hydrolysed marine collagen peptides, sourced from sustainably caught fish. Naticol® is a Type I marine collagen and holds Friends of the Sea certification for responsible sourcing.
Any time that you will remember. There is no evidence that timing changes the outcome, with or without food. Most customers take it first thing as a habit.
Liquid marine collagen is hydrolysed collagen peptides already dissolved, ready to drink. Our powder uses the identical Naticol® collagen but needs mixing. Tablets rarely carry a full 10,000mg dose, so you would take several.
Hydrolysed peptides are absorbed efficiently in any format. The practical difference is dose. One sachet delivers the full 10,000mg with nothing to break down first, whereas most tablets require several to approach the same amount.
Eight to twelve weeks of daily use is the typical window customers report. Skin and nails are often noticed first. Take it every day rather than occasionally, as collagen depends on consistent intake.
Our marine collagen is derived from fish, so it is not suitable if you have a fish allergy. Fish is declared as an allergen on the label. If you have a shellfish allergy, please contact our team before ordering so we can help.
Yes. Many of our customers start taking collagen during perimenopause and menopause.
There is no added sugar. Sweetness comes from steviol glycosides, a plant-derived sweetener from the stevia leaf, alongside natural flavouring. The full ingredient list is on this page, including 10,000mg marine collagen peptides, vitamin C, four B vitamins and L-lysine.
Each box contains 14 sachets, a two-week supply at one sachet daily. Most customers subscribe to a monthly delivery of two boxes, which arrives automatically with free UK delivery and can be paused or cancelled at any time.

I have tried various collagen products couldn’t cope with the underlying taste until I tried Kollo liquid sachets… haven’t looked back. I am 65 years old the joint pain in my wrists have gone my skin is brighter and my nails much stronger . Will never stop. Great job Kollo
I’ve been using kollo on and off for a couple of years now and I really miss it when I run out! It helps me feel more energised and active and makes my skin feel more alive and hydrated. I would recommend this trusted brand to everyone!
Some hair growth observed
As a 75-year-old woman who noted her hair was thinning. I decided to look into collagen supplements. Thought I’d give Kollo a try. I did not expect miracles , however I have noticed my hair is not falling out as much and there seems to be some regrowth . I’m aware improvements will take some time. I’ll get back to you in a few months , but so far I’m reasonably impressed and that’s praise coming from me.
Very good overall
