An honest guide for people who already take creatine
Already on creatine? 7 reasons gym regulars are switching to one sachet with the 10g of collagen they have been skipping.
5g creatine monohydrate10g collagen proteinFits in the gym bag
One sachet: 5g creatine monohydrate, 10g hydrolysed collagen, vitamin C. Mixed Berry or Tropical.
You know creatine works. What you probably do not know is what the collagen half does for the tendons, cartilage and bones your training loads, or that it is 10g of protein. Here is the all-in-one case, and what people who switched say.

If you train regularly, creatine is probably the one supplement you would defend. Fair enough: it is the most researched one there is, and the authorised claim, performance in successive bursts of short-term, high-intensity exercise, is exactly the work you do in a session. The tub has been in the kitchen for years.
Collagen, meanwhile, you have filed under skincare. That is the marketing's fault, not yours. Ten grams of hydrolysed collagen is 10g of protein aimed at the structures that take the load in training, the tendons, cartilage and bones, which adapt far more slowly than muscle. Most people who train never take it, because it comes in a second tub that clumps. This is the case for taking both, in one sachet you will keep in the bag.
Who this is written for: you train three or more times a week, you already take creatine and rate it, you have a tub or two of powders and a shaker in rotation, and you have never taken collagen because nobody explained what it is for in training terms. If you want the cheapest possible creatine per gram and nothing else, this is not that, and we say so below.
1Reason one
Muscle adapts in weeks. Tendons, cartilage and bone adapt in months. Creatine feeds the first; collagen protein is aimed at the second.
This is the bit the tub never told you. Your creatine works on the muscle: it increases physical performance in successive bursts of short-term, high-intensity exercise. But every rep also loads the tendons, cartilage and bones, and those tissues turn over on a timescale of months, not weeks. Collagen is 10g of protein per sachet, and protein contributes to the maintenance of muscle mass and of normal bones. The vitamin C in the sachet contributes to normal collagen formation for the normal function of cartilage and bones. That is the training case for collagen, in the register's own words.
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.
“Superb tasting product. 5g creatine and the collagen is a great idea. Really good post workout and refreshing”
The honest bit. Collagen has no authorised health claim of its own in Great Britain, and "recovery" is not an authorised claim for either ingredient. What stands up is above: creatine for repeated hard efforts, protein for muscle mass and bones, vitamin C for collagen formation in cartilage and bones. That is what this page claims.
2Reason two
Your creatine dose does not change. 5g of monohydrate, the same as the tub, with the 10g of collagen already in it.
Nothing is watered down to make room. KUDU's sachet carries 5g of creatine monohydrate, the full maintenance dose and the form used in nearly all the research, plus 10,000mg of hydrolysed collagen peptides, the same daily dose the big collagen brands sell on its own, plus vitamin C. Most combination products give you 2 to 3g of creatine and a token pinch of collagen; this is the full dose of both.
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.

Per 19.5g sachet, from the label: energy 44kcal, protein 10g, sugar 0.1g, fat 0g. Informed Sport tested. Made in the UK.
“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.”
3Reason three
One flavoured sachet replaces the creatine tub, the collagen tub and the shaker you keep forgetting to rinse.
You already know plain creatine is gritty and tastes of nothing, and that the shaker is the reason it gets skipped on non-training days. A sachet is pre-measured and flavoured, Mixed Berry or Tropical, and dissolves in cold water in seconds. Same daily habit, one fewer tub, no shaker.
“Absolutely addictive. Tastes like tangy orange. Have it every day with the KUDU water bottle on the way to work.”
“Easy to mix and tasty”
4Reason four
It is 44 calories and 10g of protein, so it counts, without being a shake.
A sachet in water is 44 calories, 10g of protein, 0.1g of sugar and 0g of fat. It goes down before a session or straight after one without the heavy feeling of a shake, and it does not fight your macros. Reviewers below say the same thing in their own words.
Straight after the session, from the bottle. 44 calories, 10g of protein, no heavy feeling.
“Great product and service. 10/10 addition for gains / nutritional goals”
“Love them so easy to hit my protein goals low calorie pop in my bag and have post workout..flavours great ..I am a convert”
5Reason five
It lives in the gym bag, so the habit survives the days you train away from home.
Consistency is the whole game with creatine, and it is even more so with collagen, which works on a months-long timescale. Tubs live in the kitchen; a 19.5g sachet lives in the gym bag, the locker or the car. Tear, pour into cold water, stir. Fifteen seconds, wherever the session was.
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.
“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”
“I have been looking for a nice tasting, low calorie protein source for on the go and am very glad I found these.”
6Reason six
It costs less than buying branded creatine and collagen separately, and it is Informed Sport tested.
Five grams a day of Zooki creatine sachets is £1.06. Ten grams a day of Vital Proteins collagen at the Boots price is £1.07. 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. Every batch is Informed Sport tested, which matters if you compete and is a decent quality-control proxy if you do not.
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. A 1kg tub of unflavoured creatine monohydrate is cheaper per gram than anything on this page, and if that is all you want, keep buying it. The sachet earns its price on the collagen you are not taking, the flavour, the bag and the test.

I already take creatine. Do I keep my tub as well?
No. The sachet carries the full 5g of creatine monohydrate, the same daily maintenance dose as a scoop from the tub. Swap the scoop for the sachet and the collagen and vitamin C come with it.
Does the collagen count towards my protein?
Yes. Each sachet is 10g of protein from hydrolysed collagen peptides, at 44 calories. It is not a complete protein on its own, so it is a top-up alongside your normal protein intake, not a replacement for it.
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 creatine. Plus the half you were skipping.
Your first box of 30 is half price with £24 of free gifts, applied automatically at checkout. Sixty days to decide if it replaces the tub.
