4.8 / 5from 460+ KUDU reviews
There is a fair chance you got here from an ad, and a fair chance your first thought was "here we go". Good. Scepticism is the right starting point for a supplement, and this page is written for it. No glow, no transformation, no doctor in a white coat.
What follows is the list of objections people raise about creatine and collagen, in the order they raise them, with the honest answer to each. Some of the answers are less flattering than an ad would like. One of the reviews quoted is one star.
Who this is written for: you train or move a few times a week, you have been told creatine is worth taking, and you have a list of reasons not to: bloating, water weight, hair, kidneys, "it is for gym lads", "collagen is a con". You want the list answered straight and then you will decide. If you are already sold, the general guide is a faster read.
1Reason one
"Just another fad." Creatine has thirty years of research behind it, and one authorised claim in Great Britain.
One KUDU reviewer left one star and wrote exactly that. Fair challenge. Creatine monohydrate is among the most studied supplements there is, and Great Britain's register authorises one claim for it: creatine increases physical performance in successive bursts of short-term, high-intensity exercise, at 3g a day or more. That is the whole authorised claim. Not brain, not mood, not menopause. If an ad promises those, it is over-reaching; this page does not.
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.
“Just another fad!”
The honest bit. Collagen is the weaker half of the argument. It has no authorised health claim of its own in Great Britain; what stands up is that 10g of collagen is 10g of protein, and protein contributes to the maintenance of muscle mass and normal bones, and that vitamin C contributes to normal collagen formation for cartilage and bones. That is what this page claims, and no more.
2Reason two
"It will make me bloated and heavier." At 5g a day with no loading, mostly no.
The bloating story comes from loading protocols: 20g a day for a week, which nobody here is asking you to do. At 5g a day the muscles fill their stores over three to four weeks, and the water creatine holds goes into the muscle, not under the skin. Most people see nothing on the scales. A few see a pound or two in the first fortnight, which is water in the muscle, not fat, and it settles.
One sachet, 5g of creatine, into cold water. No loading week.
“Fantastic taste (I tried orange this time) and easy to take No after effects or upset stomach etc”
3Reason three
"It causes hair loss." One small study, never repeated.
The worry comes from a single 2009 study of rugby players that measured a rise in a hormone linked to hair loss. It did not measure hair, it used a loading dose, and it has never been replicated. There is no study showing creatine causes hair loss. It is the most repeated creatine fear online and the one with the least behind it.
Sceptics welcome. The evidence is the same whoever reads it.
“Superb tasting product. 5g creatine and the collagen is a great idea. Really good post workout and refreshing”
The honest bit. "Never shown" is not "proven impossible". If you have a strong family history of hair loss and it worries you, that is a fair reason to skip creatine altogether, and no page should talk you out of it.
4Reason four
"It is for gym lads." The authorised claim is about short, hard efforts, not about who you are.
Intervals, hills, sets, sprints, the last flight of stairs: that is what "successive bursts of short-term, high-intensity exercise" means. The protein in the collagen half contributes to the maintenance of muscle mass, which is the thing that goes if you let it, at any age and either sex. The tub-with-a-bodybuilder-on-it is a marketing choice from the nineties, not a description of who benefits.
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.
“My 5k times are not coming down but at my age I am just grateful they are not going up.”
“Excellent product - tastes great, and is really helping me feel better on the bike.”
5Reason five
"Collagen powder is a con." Most of it is a proper dose sold with improper promises.
Two things are true at once. Collagen brands make claims about skin, joints and hair that the register does not authorise, and the advertising regulator has ruled against some of them. And 10g of hydrolysed collagen is, plainly, 10g of protein, at a dose that the biggest brands sell on its own. KUDU's sachet carries that full 10,000mg, with vitamin C, and makes only the protein and vitamin C claims. Whether you want collagen at all is your call; if you do, this is an honest version of it.
“Have slotted these into my daily routine and it’s helping me keep my protein intake up without having to add too much food/calories”
6Reason six
"It will taste like the sea and sit at the bottom of the glass." That is the tub, not the sachet.
Plain creatine is gritty and tastes of nothing; collagen powder clumps in cold water. Both need a shaker. KUDU's sachet is pre-measured and flavoured, Mixed Berry or Tropical, and dissolves in cold water in seconds. It is 44 calories, 0.1g of sugar, sweetened with sucralose, and the reviews below are what first-box buyers said about the taste.
TearOpen one sachet. It is 19.5g, about the size of a ketchup sachet, so it lives in a pocket or bag.
PourEmpty it into 300 to 500ml of cold water. Bottle, glass, whatever is in front of you.
StirA few stirs or a shake and it has dissolved. Drink it whenever suits: with breakfast, before training, on the way to work.
15s
Roughly how long it takes once you have done it twice. No scoops, no shaker, no measuring.
“Absolutely addictive. Tastes like tangy orange. Have it every day with the KUDU water bottle on the way to work.”
“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.”
The honest bit. Taste is personal. Some of KUDU's liquid collagen reviewers disliked one of that range's flavours, and someone will dislike one of these. That is what reason seven is for.
7Reason seven

“Product is really really good. Boxing is super slick and love the water bottle. Nicely surprised by this.”

Tick what applies and we will tell you straight.
Probably not for you if: you have a kidney condition or take prescription medication (ask your GP first), a family history of hair loss worries you, or you are vegetarian or vegan (the collagen is bovine).

Order a box, take it for up to two months, and if it is not for you, contact KUDU and you get your money back. It is the same guarantee the product page carries, and it covers taste as much as anything else.
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).
