Collagen is the most abundant protein in your body and a key building block of your skin. From around your mid-twenties, your natural stores begin to fall.
Zooki feeds your body collagen the way food does, from the inside. One sachet delivers 11,000mg of hydrolysed marine collagen, the protein your skin is made from, in a form your body can take up easily.
We'd rather you feel the difference than take our word for it.
That's why your first order arrives with an additional six free products, more than £100 worth, so you can discover what works for you (including one of our signature frosted glass water bottles).
Most collagen capsules contain 2,000 to 5,000mg. Well below a meaningful daily amount. Zooki gives you 11,000mg in every Super Strength sachet. The strongest marine collagen sachet on the market.
If you have taken collagen before and felt nothing changed, the amount is usually why. With Zooki, you are giving your body a proper daily dose of the protein it is built from.
Multiple flavours, designed to be looked forward to rather than something you have to force down.
Mango Peach. Sour Cherry. Blackcurrant. Or the Variety Pack if you want all three.
"An investment for your health! Taking Zooki collagen sachets is such a nice treat! It’s hard for me to forget to take it, I always look forward to taking it. I’ve tried all the flavours and my favourite is the mango peach, I keep mine in the fridge which makes it taste even better. I have dry/combination skin and I’ve noticed that after taking the collagen for about 3 weeks, it’s not dry anymore but hydrated and plump. I’ve looked and compared other brands and I think this is worth the investment for how much collagen you get and the results."
Individual results can vary.
Collagen is the structural scaffolding behind your hair's thickness, your nail strength, your joint flexibility, and your bone density. When you get enough of it in your diet, your whole body benefits.
Within weeks, women consistently report stronger nails, less hair shedding, and joints that feel less stiff.
Drizzle over yoghurt and fruit, mix into a smoothie or take straight from the sachet.

"Zooki Collagen tastes amazing"
"The secret weapon of successful people"
"I started to receive compliments on my "glowing" skin"
"Best all-round collagen"
Katie L.
"Since getting older I started to notice the wrinkles on my forehead which I really wanted to clear. I was recommend to try Zooki Collagen which massively helped my skin and made my skin feel very bright. After a few months my face was completely clear! Then I tried the Super Strength Collagen and WOW! The pictures say it all…no spots and no wrinkles, I honestly cannot believe the results I have seen. Highly recommend Zooki collagen/super strength! I could not live without this in my morning routine."
Nicole L.
“I have been using Zooki Collagen now for 2 months and I am amazed by the visible results which I noticed pretty quickly. I see a marked improvement in fine lines round my eyes and my skin’s surface generally appears smoother. I’ve also never felt as confident wearing no make-up. I’ve used various collagen supplements over the last couple of years and can honestly say I’ve never seen a difference until I started using Zooki. I wish I’d started sooner. Not a bad start to having just turned 40!”
Stephen D.
"As I’m nearing my 50th milestone, I was noticing deeper lines around my eyes and forehead. Within 4 weeks of starting the daily course of Zooki 5000mg, I was seeing a vast improvement around my eyes. Smoother skin too around my nose. Within 8 weeks, the lines around my eyes had mostly disappeared. Zooki is truly a miracle force."
Sinthu S.
"I first tried zooki after being recommended it by a friend I did 90 days of collagen zooki super strength the flavour (blackcurrant) is absolutely delicious.I saw quite a few changes in my energy and nail growth my nails felt stronger and more healthy my skin was also glowing more than usual. Very satisfied with the results."
Mel
"Been using for over a month and my skin has improved 100 percent. Neck area which was my turkey neck is amazing, I feel less self-conscious and I feel my face looks more glowing."
Teresa M.
"I've been taking the super strength collagen for over 3 months now and have noticed a difference in my nails and hair. Definitely feel like my nails are a lot stronger and my hair fuller. My nails used to be so brittle. If only it would get rid of my grey hairs then it would be spot on.The sachets of collagen themselves were very easy to take. I’d pour a sachet into my ginger shot every morning. I put it into my morning routine and it slotted in perfectly."
Julie A.
"I just love Zooki Collagen Berry Flavour as part of my daily regime for the past year. My skin is so much softer and younger looking."
Zooki is designed to be something you look forward to — not something you have to force down.
Recognised for our commitment to quality, efficacy, and customer experience.
Voted the UK's Best All-Round Collagen supplement 4 years running by ExpertReviews - an independent team of experts who've been rigorously testing products since 1987.
A clinical trial found significant improvements in skin elasticity, hydration and smoothness for those who took Zooki collagen compared to the placebo in as little as 4 weeks.
Elasticity
Those who took collagen saw increased in elasticity over the study period. Those who didn't take collagen saw their skin become less elastic.
Hydration
Skin hydration increased over time for those who took collagen. Those who didn't take collagen saw their skin become more dehydrated over the same period.
Roughness
Those who took collagen rather than the placebo saw a bigger increase in skin smoothness.
30 days of Zooki Super Strength Collagen, delivering 11,000mg per sachet. The strongest single-serve marine collagen on the market. Clinically proven to improve skin hydration, elasticity, and smoothness in just 4 weeks. This is the foundation everything else builds on.
Your body can't form new collagen without Vitamin C. It's a non-negotiable part of the process. Zooki's liposomal Vitamin C delivers up to 4x higher absorption than standard supplements, so more of it reaches the cells where collagen synthesis actually happens. Collagen and Vitamin C together, not separately.
Magnesium drives protein synthesis, the process your body uses to turn the collagen you consume into actual structural repair. It also supports sleep quality, which matters more than most people realise. Your skin does its heaviest repair work overnight.
Vitamin D supports the cell division process that produces healthy new skin cells. It also plays a key role in immune function and mood. Most people in the UK are deficient, especially through autumn and winter. A simple daily addition to support skin renewal from within.
High strength, sugar-free electrolytes with added ingredients clinically proven to enhance skin radiance. Well-hydrated skin appears plumper and more luminous. Dehydration is one of the fastest ways to undo good skincare. This keeps your skin looking its best between sachets.
A daily energy and focus blend designed for the mornings you need to be sharp. B vitamins, Vitamin C, and zinc to keep you steady through early mornings, long afternoons, and everything in between. Sugar-free, mix with water.
Hydration is non-negotiable for skin that looks and feels healthy. A reusable glass bottle designed to make your daily collagen and hydration ritual effortless and consistent. Because consistency is what makes collagen work.

We offer both 5,000mg regular strength and 11,000mg Super Strength options, both available multiple delicious flavours.
Unlike many liquid supplements, this formula contains no artificial flavourings, sweeteners or preservatives – only carefully selected ingredients for a clean, natural taste.
Ingredients (shared across all flavours):
Flavourings:
Both options contain the same premium, hydrolysed marine liquid collagen peptides - the only difference is the the strength per sachet and the flavours you can opt for.
Nutrition (per sachet):
This is a liquid marine collagen supplement sourced from fish, so it is not suitable for vegans.
Zooki Liquid Collagen is a marine collagen sourced from fish, not beef, so it is halal.
No, however it tastes best chilled!
This sachet is packed with hydrolysed marine Type 1 collagen, which we source from sustainably-sourced white fish - cod, to be specific.
Collagen in its natural state is a large chain of individual peptides that is impossible for the body to absorb. In order to help your body absorb the collagen, we 'hydrolyse' into smaller molecules that are smaller and easier for your body to absorb!
We always recommend those who are pregnant or breastfeeding check with a medical professional before they take any new dietary supplement.
