Multi-award winning

Not only is Zooki Super Strength Collagen the highest strength liquid marine collagen dose available on the market, but it also uses a premium source of hydrolysed marine collagen that is readily absorbed and utilised by the body - and has been recognised accordingly.

As well as being named the UK’s “Best all-round collagen supplement” by expertreviews, 3 years running, Zooki Super Strength Collagen won gold at the Beauty Supplement Awards for “Best Beauty Supplement” and “Best Nutritional Supplement” at the Free From Food awards. See the comments from the judges below.

"Zooki Super Strength Collagen delivers an impressive 11,000mg of marine collagen per sachet, making it a powerful choice for those needing extra support due to age, more damaged hair, skin, or nails, or simply wanting faster results. The great taste makes it feel more like an indulgence than a supplement, making it a beauty boost you’ll actually look forward to every day. While the convenient sachet can easily be added to a drink, I personally had it straight from the packet —it’s that tasty!"

- Charissa R, Beauty Supplement Awards

"The use of hydrolysed collagen (which are collagen peptides) rather than 'collagen' makes this a valid product formulation for a person hoping for skin or connective tissue benefits. The collagen content is very high which stands it apart from the competitors. The aroma is good and the initial flavour delivery is very good. The texture is thick but it can be taken in water or on food. A great product that does deliver."

- Free From Food Awards

"These flavoured shots are a tasty way to get your daily dose of high-quality hydrolysed marine collagen – the type all our experts recommended as the best for fast, efficient absorption by your body. It contains no artificial sweeteners, just 100% natural sustainably sourced ingredients, including hydrolysed fish-based collagen peptides. It’s about as efficient a collagen supplement as you can get, and very convenient."

- Expertreviews

The Gold Standard of collagen

Voted the UK's Best All-Round Collagen supplement three years running by ExpertReviews.

Premium marine source. Made with hydrolysed marine collagen, a premium alternative to bovine and porcine sources.

High strength. 5,000mg of marine collagen in every sachet.

Hydrolysed. Hydrolysed to under 10 kilodaltons, giving a fine, low molecular weight peptide that's easy for your body to absorb.

Trusted and recognised. Recognised across leading beauty and nutrition awards, and chosen by thousands of customers across the UK.

Backed by clinical research

In an 8-week double-blind study, 56 women were given either a) a 2.5 gram daily dose of the collagen used in Zooki collagen products or b) a placebo. The study found significant improvements in skin elasticity, hydration and smoothness for those who took collagen compared to the placebo in as little as 4 weeks.

Improved skin elasticity. Those who took collagen saw an increase in elasticity over the study period. Those who didn't take collagen saw their skin become less elastic.

Improved skin 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.

Improved skin smoothness. Those who took collagen rather than the placebo saw a bigger increase in skin smoothness across the eight weeks.

Zooki Collagen success stories

Katie L.

I honestly cannot believe the results

"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 wish I started sooner

“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.

Zooki is truly a miracle force

"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.

Very satisfied with the results

"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

I feel less self-conscious

"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.

My nails are a lot stronger and my hair fuller

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.

FAQs

Please read our FAQs page to find out more.

How much collagen is in each sachet?

We offer both 5,000mg regular strength and 11,000mg Super Strength options, both available multiple delicious flavours.

What are the ingredients?

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):

Water – the base that carries all the other ingredients.
Glycerol – a natural humectant (from plants) that helps keep the liquid smooth and stable.
Marine Collagen Peptides (from fish) – hydrolysed collagen proteins, broken down into smaller peptides for easy absorption.
Acidity Regulators (Tartaric Acid, Citric Acid, Malic Acid) – found naturally in fruits like grapes, citrus, and apples, they balance taste and help preserve freshness.
Vitamin C (Ascorbic Acid) – an essential vitamin that supports collagen formation and overall health.
Natural Flavourings – enhance the fruity taste profile.
Gelling Agents (Cellulose Gum, Xanthan Gum) – plant-based thickeners that give a smooth, consistent texture.
Botanical Extract (Rowanberry – Sorbus aucuparia L.) – a natural fruit extract with a subtly tart flavour.
Emulsifier (Sunflower Lecithin) – helps oil- and water-based ingredients blend smoothly.
Vitamin E (Tocopherol) – a nutrient that also acts as a natural antioxidant, helping keep the product fresh.

Flavourings:

Berry flavour – with lemon juice for brightness and sour cherry juice (from concentrate) for a tangy fruit twist.
Mango Peach flavour – with mango purée for a smooth, tropical flavour.
Citrus Lime flavour – with lime juice (from concentrate) and lime extract, plus natural lemon & lime flavouring for a zesty, refreshing taste.

What's the nutritional information?

Nutrition (per sachet): Energy – ~152–153 kJ / 36 kcal; Fat – 0.03 g (of which saturates – 0 g); Carbohydrates – 4.6 g (of which sugars – 0.01–0.05 g); Fibre – 0.06 g; Protein – 5 g; Salt – 0.09 g; Vitamin C – 80 mg (100% NRV); Vitamin E – 3.6 mg (30% NRV).

What's the difference between 5,000mg and 11,000mg Super Strength Collagen?

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.

Is Zooki Collagen vegan?

This is a liquid marine collagen supplement sourced from fish, so it is not suitable for vegans.

Is Zooki Collagen halal?

Zooki Liquid Collagen is a marine collagen sourced from fish, not beef, so it is halal.

Does it need to be kept in the fridge?

No, however it tastes best chilled!

What's the source of collagen and what type of collagen is it?

This sachet is packed with hydrolysed marine Type 1 collagen, which we source from sustainably-sourced white fish - cod, to be specific.

What is 'hydrolysed' collagen?

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!

Can I take it if I'm pregnant or breastfeeding?

We always recommend those who are pregnant or breastfeeding check with a medical professional before they take any new dietary supplement.

Reviews

Fantastic sachet that actually taste good

"Zooki is great! I'm on my second month of collagen and I'm loving it. The taste is great! I've tried many brands and I can guarantee you that it's the first one that I find that does not have the taste of fish! What a pleasure to take your supplement without after taste. I'm not seeing success yet, but I know the benefits of collagen, I'm 34 so I'm taking it more as prevention. I will keep my subscription for a long time, I finally found a brand that I like!"

— Oriane E. (5/5)

I've been using Zooki Glutathione

"I've been using Zooki Glutathione and Liquid Collagen, and I'm genuinely impressed with the results. My skin feels more hydrated, looks brighter, and has a healthy glow. It's also feeling smoother and more supple. So far, it's been a great addition to my skincare routine!"

— Ajibola O. (5/5)

Great product

"I have been using zooki for a few months now and I have noticed positive effects on my skin, nails and hair. I really like that it is portioned into sachets, easy to use and have on the go too. I tried different flavours, the mango & peach is my favourite!"

— Linda N. (5/5)

Help with fine lines and body aches

"I have been taking the cherry collagen 11000 mg sachets for a few months now and can honestly say I love them. I’ve noticed my nails are stronger, my fine Lines on my face have improved and I have less body aches which is a bonus. Love them and they are now part of my daily routine along with the skin radiance electrolytes."

— Rosslyn S. (5/5)

Great collagen, been taking Zooki

"Great collagen, been taking Zooki collagen for over 3 months now. My skin feels tighter and less wrinkly already. I have tried other marine collagen and there was no change in my skin at all. Best product I gave tried so far and certainly recommend it."

— Oosha C. (5/5)

Post cancer health boost.

"We have been using Zooki for a long time now. I started using them after radiotherapy treatment and to help with an arduous work programme in the movie industry. My wife started using them soon afterwards as a daily supplement. They’re very easy to use, to travel with and feel like they work instantly. Can’t recommend them highly enough."

— Julian W. (5/5)

Skin game changer

"Great flavour selection and works from day 1. My skin definitely feels smoother and tighter. I didn’t really have lines, but visibly skin is very much improved and plumper. I highly recommend this product"

— Dami S. (5/5)

A staple in my routine

"It's very tasty and quick to ad to a morning routine. I've noticed since taking it consistently that my skin feels softer and healthier even in winter. I don't know if it's just a coincidence, but my hair has also started growing out a lot thicker and I notice it growing in areas that it hasn't grown recently. I didn't start taking this for hair growth but I'm super pleased with what I've noticed. This is the only supplement I splurge on and I will continue to use it."

— Sabrina I. (5/5)

Noticeable difference

"Since resuming taking the extra strength collagen I have noticed a renewed plumpness in my face and lines around eyes and mouth are less pronounced. I have recommended theses delicious sachets of goodness to my friends."

— Michelle F. (5/5)

Already seeing improvements

"Been taking for almost a month and have already seen improvements in my skin and nails. My nails are stronger, stopped breaking and have grown super long. Will definitely be continuing to take zooki and would 100% recommend."

— Krishna M. (5/5)
