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.
The collagen maths
One shot.
Two litres of broth.
Each KUDU shot delivers 20g of hydrolysed collagen — about the same you'd get from drinking two litres of bone broth. In two sips, not a 24-hour simmer.
1 KUDU shot
20g collagen · 2 sips
=
2 litres
of bone broth
*Based on roughly 10g of collagen per litre of typical shop-bought bone broth, versus 20g of hydrolysed collagen per KUDU shot. Home-made broth can be richer.
Why KUDU
Most protein looks after your muscles.
This looks after everything else.
20,000mg of hydrolysed collagen in every sachet — the same daily dose recommended by skin clinics and used by professional athletes. Tap each row to see what that means for you.
-
Collagen rebuilds the connective tissue, tendons and joints that whey ignores. Less soreness the morning after. Back training sooner.
-
20,000mg per day is the dose skin clinics recommend. Fewer wrinkles, better hydration, visible glow — from within, not from a jar.
-
Collagen is the building block of cartilage. Daily use supports joint comfort and long-term mobility — whether you train hard or just want to keep moving well.
-
Minimal ingredients. No dairy, no artificial junk, no bloat. The protein hit your stomach actually agrees with.
-
85 calories. Zero sugar. Zero fat. Half the calories of a protein bar, none of the syrups, none of the additives.
-
Ready to drink. Rip the top, drink in two sips, get on with your day. No shaker, no scoop, no washing up.

A note from the founders
“We couldn’t find a clean protein that looked after joints and skin too.”
No sugar, no bloating, no shaker bottle in the kitchen sink. Just a proper dose of collagen you can drink and get on with your day. So we built it.
— Ed & Sam, Founders of KUDU

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.

Amazing product and love the taste

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!
