The best-value collagen in the UK.

The collagen clock
Your collagen is
running out
From your mid-20s, your body makes about 1% less collagen every year. For women, the drop turns into a cliff at menopause — losing up to a third of skin collagen in just five years.
Men – a slow, steady slideWomen – a cliff at menopause
↓Sagging skin↓Thinning hair↓Sore joints↓Weaker bones↓Slower recovery
Illustrative, based on published research into dermal (skin) collagen, which falls roughly 1% per year from the mid-20s. Individual rates vary.
Absorption
Not all collagen gets in.
Collagen is a huge protein. Your gut can't absorb it whole — it has to be chopped into small peptides first. Hydrolysed collagen arrives pre-chopped. It's the only kind we use, and we dissolve it for you.
The gut-wall test
Small enough to pass, or too big to get in
In your gut
Into your blood
Gut wall
Whole collagenBone broth, gelatin, tablets. Too big to absorb as it is — much of it never gets in as usable peptides.
Hydrolysed collagen · KUDUPre-cut peptides, a fraction of the size. In trials, collagen amino acids rise in the blood within about 20 minutes.
Bone broth
~2 litres
~10g collagen per litre, mostly whole. Two litres to match one shot.
Tablets
20+ pills
500–1,000mg each. A fistful a day to reach 20,000mg.
Powder
1 heaped scoop
Often hydrolysed too — but 20g is a scoop to measure, shake and wash up. The routine most people drop.
KUDU liquid
2 sips
20,000mg already dissolved. Rip, sip, done — so you actually do it every day.
Absorption: Skov et al., 2019 — on our Research page. Broth figure based on ~10g collagen per litre of shop-bought broth.
Beyond beauty
Most collagen stops at your skin.
20,000mg goes deeper.
Skin needs a little. Tendons, joints and muscle were studied at a lot more. Drag the dose and see how far it reaches.

Questions
You ask, we answer.
Everything you’re probably wondering before you hit add to cart.
-
Broken down, it’s £2.49 a sachet — less than your morning coffee and even less on our subscription. But instead of a caffeine spike you’re getting 20,000mg of collagen protein. A single product has 6+ tangible body benefits.
Most customers cancel at least one other supplement once they start KUDU.
-
Most customers feel the recovery difference within 2 weeks. Skin and hair results typically become visible at 4–6 weeks of daily use.
Collagen works cumulatively — the longer you take it, the better it works. Which is why we offer subscription: so you never have a gap.
-
Whey builds muscle. Collagen builds everything else — joints, tendons, cartilage, skin, hair and nails. Whey contains zero collagen.
If you’re training hard, you need both. But because KUDU’s collagen also contributes to muscle mass, many customers replace their whey entirely.
-
Every batch is Informed Sport certified — the same standard used by Olympic and Premier League athletes.
Every ingredient is listed on the label. No proprietary blends, no hidden additives. What you see is exactly what’s in the sachet.
-
Start with a single 14-pack rather than a subscription — if it’s not for you, you’re only out one box. But most customers reorder before they finish the first.
-
KUDU contains hydrolysed bovine collagen so it’s not suitable for vegans or vegetarians. It is dairy-free and gluten-free.
Bovine collagen at 20g is currently the most bioavailable and cost-effective format at this dose — which is why we’ve started here.
-
Like a fruit shot, not a supplement. Four flavours: Sour Cherry, Orange, Peach, and Strawberry & Vanilla. One flavour per box, 14 sachets in each.
No chalky aftertaste, no protein-shake heaviness — it’s designed to be the easy bit of your day.
Pro tip: tastes even better straight from the fridge.
-
Post-workout for recovery, morning for a daily habit, or anytime that suits. Up to 3 sachets a day — most people take one.

Love them!

Amazing product and love the taste
C
Sour cherry is a great flavour and the sachet is easy to take on the go. I tried a sample box too which was very generously gifted to me with my first order and I liked the other flavours. Orange I think is my favourite. I definitely feel fuller and have piece of mind that I’m increasing my protein and collagen intake. Too early to see any skin or hair changes I think but I’m going to order another box and I’ll report back with before and after of skin. A brilliant nice tasting product for busy people.

Very good product, tasty not to sweat. I feel much more better and stronger after taking kudu collagen.
S
Have been on Kudu since the beginning when they first set up and have loved having such a quick and crucial source of protein; especially with my intense work/life balance and focus to workout and run as frequently as possibly.
I have recently become a new dad and as I am now adapting myself to the new normal; workouts have become less frequent / re prioritised while conscious protein intake has become a little more difficult - thanks to KUDU, however, I have instant and easy access to my daily crucial protein source.
J
Love the cherry !
B
Taste is fabulous ( all 3 flavours) .. have them from the fridge if you can .. slightly thicker consistency which makes it feel more substantial .. incredible protein to calorie ratio … big fan! (Fat boy getting slim!)

Kudu Collagen Protein – A Total Game Changer!
I’ve tried a lot of protein supplements, but Kudu Collagen Protein is on another level. From the first sip, I was impressed not just by the great taste (especially the sour cherry one), but by how smooth and easy it is to drink. Unlike many protein powders that can be clumpy or chalky, Kudu comes in a convenient, ready to drink sachet that makes getting high quality collagen effortless.
Each serving delivers 20g of hydrolyzed bovine collagen with zero sugar and only 85 calories, making it a perfect choice for anyone focused on lean muscle recovery, joint support, and overall well-being. I’ve personally noticed a difference in my post workout recovery, less soreness, better flexibility, and even improvements in my skin and hair.
The fact that it’s pre mixed and travel friendly makes it super convenient, whether you’re at the gym, at work, or on the go. If you’re serious about performance, recovery, and health, Kudu Collagen Protein is a must have in your routine. Highly recommend!

i popped my knee over a week ago, and I believe the collagen has been a major part of my recovery and a big part of my daily protein intake
A
Great protein boost
C
It is unfortunately my least favourite flavour but that is just personal preference. The orange and.peach are my absolute fav, but I'm not reviewing them hence the 3 stars. The products over all are of great quality and worth every penny.
