Your training has not slowed down. The days after have. 7 reasons people who train hard are taking collagen and creatine in one sachet.
5g creatine, no loading10g collagen proteinFits in a gym bag
One sachet: 10g hydrolysed collagen, 5g creatine monohydrate, vitamin C. Mixed Berry or Tropical.
The sessions are the same. Coming back from them is not. Here is what 10g of collagen protein and 5g of creatine a day do for the person who trains, what they do not, and what people who started say.

4.8 / 5from 460+ KUDU reviews
There is a point where the training does not change but the maths does. Two hard days back to back used to be fine. Now the second one costs something, and the day after that costs more. You have not got slower in the session. You have got slower between them.
Most of what is sold for this is either a protein shake you do not want to drink at seven in the morning or a tub of creatine with a bodybuilder on it. The two ingredients that the research keeps pointing at for people who train, muscle protein and creatine, have never been sold to that person in a format they would keep up. That is what this page is about.
Who this is written for: you run, ride, lift, row or play something three or more times a week, you are past the age where recovery was free, and you want the two supplements with the best evidence behind them in one habit you will keep. If you want a mass gainer or a pre-workout, this is not that.
1Reason one
Creatine's authorised claim is about exactly the efforts that hurt the next day: short, hard, repeated.
The claim as authorised in Great Britain: creatine increases physical performance in successive bursts of short-term, high-intensity exercise, at 3g a day or more. Intervals, hills, sets, sprints, the repeated efforts that make up a hard session. KUDU's sachet carries 5g of creatine monohydrate, the form and the dose used in most of the research, taken daily with no loading phase.
10ghydrolysed collagen peptides. The same 10,000mg dose sold on its own by the big collagen brands.
5gcreatine monohydrate. The full daily dose, in the form used in most of the published research.
+ Vit Ccontributes to normal collagen formation for the normal function of cartilage and bones.
Per 19.5g sachet, from the label: energy 44kcal, protein 10g, sugar 0.1g, fat 0g. Informed Sport tested. Made in the UK.
“Superb tasting product. 5g creatine and the collagen is a great idea. Really good post workout and refreshing”
The honest bit. Creatine does not have an authorised claim about recovery, and this page will not give it one. What it is authorised for is performance in repeated hard efforts. The protein half carries the maintenance-of-muscle-mass claim. Together that is the honest case.
2Reason two
Ten grams of collagen is 10g of protein, and protein contributes to the maintenance of muscle mass.
Every sachet carries 10,000mg of hydrolysed collagen peptides. That is 10g of protein, and protein contributes to the maintenance of muscle mass and of normal bones. Vitamin C is in the sachet because it contributes to normal collagen formation for the normal function of cartilage and bones. It is the same 10g dose the big collagen brands sell on its own, taken daily by the person doing the work.
Weeks 1 to 4Creatine reaches saturation.Taken daily at the full dose, creatine tops up your muscles' stores. The authorised claim: creatine increases physical performance in successive bursts of short-term, high-intensity exercise.
Every day10g of protein per sachet.Protein contributes to the maintenance of muscle mass and of normal bones. That is the job the collagen is doing, sachet by sachet.
Week 8 and onThe long game.Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones. Consistency is the active ingredient, which is why this is built to be easy to keep up.
“Excellent product - tastes great, and is really helping me feel better on the bike.”
“My 5k times are not coming down but at my age I am just grateful they are not going up.”
3Reason three
It is 44 calories and it is not a shake, so it happens at seven in the morning.
The reason protein habits fail is the shake: the heavy feeling, the smell, the blender. A KUDU sachet is 44 calories, 10g of protein, 0.1g of sugar, and it tastes like a soft drink in cold water. It goes down before a session or straight after one without sitting in your stomach.
Straight after the session, from the bottle. 44 calories, no heavy feeling.
“Handy way to get my protein intake in especially when I don’t want the heavy feeling after a protein shake!”
“I hate the smell of protein! But this product is perfect for me. There's no any protein smell or taste. And it also really convenient to consume it! Easy and fast)))”
4Reason four
It lives in the gym bag, so the days you train away from home still count.
Consistency is the whole game with creatine: three to four weeks of daily dosing to saturate the muscle, and a missed week sets you back. Tubs live in the kitchen. A 19.5g sachet lives in the gym bag, the jersey pocket, the glove box. Tear, pour into cold water, stir. Fifteen seconds, wherever the session was.
A week of sachets in the gym bag, next to the bottle.
“Absolutely addictive. Tastes like tangy orange. Have it every day with the KUDU water bottle on the way to work.”
“Great product, just slip one in your bag on the way out the door for work and tastes amazing will definitely be buying more of these”
5Reason five
One sachet replaces two tubs and a shaker, which is why it is still happening in week eight.
Plain creatine is gritty and unflavoured; collagen powder clumps in cold water; both need a shaker that needs rinsing. Two tubs is two habits, and two habits are twice as easy to drop. One flavoured sachet that dissolves in seconds is the format people keep.
“Love love LOVE the tropical flavour collagen protein, Vit C and creatine sachets. These are so handy and so delicious they have slotted right into my life and routine. Already feeling the benefits with consistency.”
“Easy to mix and tasty”
6Reason six
It costs less than buying the two ingredients separately.
Ten grams a day of Vital Proteins collagen at the Boots price is £1.07. Five grams a day of Zooki creatine sachets is £1.06. Together, £2.13 a day. A KUDU sachet with both, plus vitamin C, is £1.00 a day on your first box and £1.34 a day on subscription after that.
Vital Proteins collagen 10g a day, Boots price£1.07
Zooki creatine sachets 5g a day£1.06
Both, bought separately two products, two scoops£2.13
KUDU, first box 10g collagen + 5g creatine + vit C£1.00

Each brand's own UK price or Boots price on 8 September 2026, converted to the cost of the same daily dose. Prices change; the comparison is checked against the product page, which updates live.
The honest bit. Bulk unflavoured tubs are cheaper per gram than any of this, and every Informed Sport batch test costs money that shows up in the price. If you are happy with two 400g tubs and a shaker, that is the cheaper route.
7Reason seven
Half price for your first box, £24 of gifts, and 60 days to decide.

“Product is really really good. Boxing is super slick and love the water bottle. Nicely surprised by this.”
Tick whichever of these is true. Ten seconds, and it tells you whether this page is for you.
Tick what applies and we will tell you straight.
Probably not for you if: you want a mass gainer or a pre-workout, you want the cheapest possible creatine per gram (buy a bulk tub), or you are vegetarian or vegan (the collagen is bovine).

Either. Both ingredients work through daily consistency rather than timing, so take it whenever it will reliably happen: before, after, or with breakfast on rest days.
Is it tested for banned substances?
Yes. Informed Sport tested, which means every batch is screened for substances banned in sport. It matters if you compete, and it is a decent proxy for quality control if you do not.
Is creatine only for people who lift weights?
No. The authorised claim is about performance in short, high-intensity bursts, which covers intervals, hills, sets, sprints and the last flight of stairs as much as the squat rack. The 5g daily dose in each sachet is the standard maintenance dose used in the research, with no loading phase.
Will creatine make me bloated or heavier?
Creatine draws water into the muscle, not under the skin. Some people see a small rise on the scales in the first week or two as the muscles top up; that is water stored where it is useful, not fat. At 5g a day with no loading phase, most people notice nothing at all.
Why put collagen and creatine in the same sachet?
Because most people who take one should be taking the other, and nobody keeps up two tubs. Collagen is 10g of protein per sachet, and protein contributes to the maintenance of muscle mass and normal bones. Creatine increases physical performance in short, high-intensity bursts. One habit covers both.
Is 10g of collagen a proper dose?
Yes. 10,000mg is the same daily dose the big collagen brands sell on its own. KUDU uses hydrolysed bovine collagen peptides with vitamin C, which contributes to normal collagen formation for cartilage and bones.
What does it taste like, and does it mix?
Two flavours, Mixed Berry and Tropical (mango and pineapple). It dissolves in cold water in seconds and tastes like a soft drink rather than a supplement. One reviewer called it addictive, another says it tastes like tangy orange. It is sweetened with sucralose and has 0.1g of sugar.
When should I take it?
Whenever you will actually take it. Both ingredients work through daily consistency, not timing. Most people have it with breakfast, on the commute or around training.
What does the first box cost, and what happens after?
Your first box of 30 sachets is £29.98 (50% off), with a KUDU bottle and a liquid collagen sampler free. After that, subscription boxes are 33% off at £40.17, or £1.34 a serving, and 40% off from box six. Delivery is free on every subscription box, and you can pause, skip or cancel anytime. One-time purchase is £44.74.
What if it is not for me?
There is a 60-day money-back guarantee. Try it for two months; if it is not for you, tell them and you get your money back.
Does creatine cause hair loss?
There is no study showing creatine causes hair loss. The worry comes from one small 2009 study in rugby players that measured a rise in a hormone linked to hair loss, and it has never been repeated. At 5g a day, the amount in one sachet, it is not something the research supports.
Is creatine safe to take every day?
Creatine monohydrate is one of the most studied supplements there is, and daily use at 3 to 5g in healthy adults has a long safety record. Drink normally; it does not need litres of extra water. If you have a kidney condition, are pregnant, or take prescription medication, check with your GP first, as you would with any supplement.
Is it tested?
Informed Sport tested, so every batch is screened for banned substances. Made in the UK. Not suitable for vegetarians or vegans (the collagen is bovine).
The decision
Same training. Better maths between sessions.
Your first box of 30 is half price with £24 of free gifts, applied automatically at checkout. Sixty days to decide if it stays in the bag.
