Can You Put Creatine in Coffee or Tea? Heat, Caffeine and Grit
Yes. Stir creatine into coffee or tea and drink it. Dissolved creatine turns into creatinine slowly: 4% over three days at room temperature in the stability data, and no study has timed the loss in a cup drunk over minutes. Caffeine has not been shown to cancel it; the trial record is ten small, mixed studies. Grit is texture, not lost dose.
Can you put creatine in coffee?
You can, and many people do, because the morning coffee is the habit nobody forgets. The worry, in one reader's words, is that "according to the internet this negates the benefits". It does not; the questions behind it are heat, caffeine and grit. The store creatine fills in muscle is explained in what creatine does; the daily method is in how to take creatine and timing in when to take creatine.
Does hot coffee destroy creatine?
No study has measured creatine in a hot cup drunk over the time a coffee takes. In solution, creatine converts to creatinine, an inactive by-product, faster as the liquid gets more acidic and hotter.1 The International Society of Sports Nutrition's 2017 position stand, citing a 2011 review, gives these figures for three days at 25 °C.1, 2
| Acidity | Converted to creatinine after three days at 25 °C | Drinks near this acidity (our estimate) |
|---|---|---|
| pH 5.5 | 4% | Slightly less acidic than black coffee |
| pH 4.5 | 12% | Slightly more acidic than black coffee |
| pH 3.5 | 21% | Orange and other citrus juices |
Two inferences follow, ours rather than measured results. Coffee is near pH 5, so the 4% and 12% rows bracket it. Those are three-day figures; a cup finished within half an hour sits at a small fraction of them, unmeasured, so we give no number. The same paper notes creatine is "relatively stable in solution at neutral pH",1 and a 2009 storage study confirmed that "creatine stability in the crystal form is very high".3
Heat is the bigger lever. A 2025 analysis stressed creatine at 60 to 200 °C and in coffee, orange juice and an energy drink, and found "temperature was the most significant factor affecting creatine stability".4 That range starts above drinking temperature, so it says heat matters, not what a cup does. Do not pour boiling water onto the powder and leave it; mix it into the coffee you are about to drink.
Can you put creatine in tea?
Yes; the same chemistry applies. Black tea is mildly acidic, broadly where coffee sits, so the table above is the best guide; green and herbal teas vary, and no study has put creatine in tea. Tea and coffee count towards your fluid for the day, the NHS says.5 The trials behind that fluid question are in does creatine dehydrate you.
Does caffeine cancel out creatine?
Ten small studies disagree, and the largest found no interference. In a 1996 crossover trial, nine men loaded creatine for six days with or without caffeine at 5 mg per kilogram of bodyweight a day; the 10 to 23% gain in dynamic torque seen with creatine alone was not seen with caffeine added.6 A 2002 trial of ten men found three days of caffeine overrode the shortening of muscle relaxation time that creatine produced.7
A 2016 trial gave 54 active men five days of creatine loading alone, with 300 mg of caffeine anhydrous, with 8.9 g of coffee, or placebo. Strength improved in every group, placebo included, with no difference between treatments; four of 13 men on caffeine anhydrous reported mild stomach discomfort, none in the coffee group.8 A 2022 systematic review of all ten studies found three in which loading did not interfere with a pre-exercise caffeine dose; with daily caffeine alongside creatine, two reported interference, three none, one synergy.9 A 2025 expert review concluded that short-term caffeine below 5 mg per kilogram a day "likely does not cause opposing muscle effects" and that daily caffeine with daily creatine "has not yet been evaluated".10
If you load, some researchers suggest taking caffeine after the loading dose; at 3 g (grams) to 5 g a day with an ordinary coffee habit, nobody has run the trial. The authorised wording for the ingredient, "Creatine increases physical performance in successive bursts of short-term, high intensity exercise", applies at a daily intake of 3 g for adults doing high-intensity exercise. Drink as you normally would; the NHS guide is 6 to 8 cups or glasses of fluid a day, more in heat or during long sessions.5 Creatine itself contains no caffeine and is not a stimulant; caffeine and sleep is about the coffee.
What else can you mix it with? Milk, juice, porridge, yoghurt, smoothies
All of them. Creatine has no known interaction with any food. Milk is close to neutral, which by the table puts it in the slowest-converting range; that is our inference, since no study has mixed creatine into milk. Juice sits where 21% converts over three days, so pour, stir and drink.1 Porridge, yoghurt and smoothies are fine; stirring it in is the whole recipe.
Protein and carbohydrate were studied for a different reason. In a 2000 study of 12 men, 5 g of creatine taken with about 50 g of protein plus 47 g of carbohydrate, or with 96 g of carbohydrate, left whole-body retention about 25% higher than with 5 g of carbohydrate, an insulin effect that "was diminished within the initial 24 h".11 A meal or shake alongside is a reasonable habit, not a reason to add sugar. Collagen goes in the same cup; can you take collagen and creatine together sets out the pairing.
Pre-dosed and flavoured formats remove the mixing question; the powder lets you choose the drink. Each delivers the creatine its label states. What to check on a pre-dosed label is in do creatine gummies work.
Why won't creatine dissolve, and does it matter?
Creatine monohydrate dissolves slowly and never completely in cold water, so grains settle; a 2003 comparison found it dissolved slowest of three creatine forms measured.12 Warm liquid and a bigger volume dissolve more; swirl the glass to finish the sediment. Undissolved is not lost: when 17 men took 2 g of creatine in water or baked into food bars, the bars slowed absorption four- to eight-fold without changing the total absorbed, and no creatine or creatinine was detectable in the stool samples.13 Where grit matters is comfort: undissolved powder and an upset stomach go together for some people, particularly on an empty stomach; take it with the coffee that comes with breakfast.
What does creatine taste like?
Unflavoured creatine monohydrate is close to tasteless, with a faint chalky note and a gritty texture if it has not fully dissolved; most complaints about the taste are about the texture. Flavoured products taste of their flavouring, with the sugar or sweetener listed on the label.
Frequently asked questions
What not to mix creatine with?
Nothing is chemically forbidden. Very acidic drinks left standing lose more to creatinine, so mix and drink. No study has tested creatine with alcohol. The firm rule is the amount per serving: in a 28-day trial of 59 footballers, a single 10 g dose doubled the rate of diarrhoea compared with 5 g taken twice (55.6% against 28.6%); 5 g at a time was no different from placebo.14 Keep each serving to 5 g or less. For the gut, see does creatine cause bloating; for medicines and conditions to raise with your GP or pharmacist, see creatine side effects.
Does caffeine cut out creatine?
Not on the evidence. Two trials of 9 and 10 men found high daily caffeine blunted creatine's effect during a loading week; a 54-man trial with coffee found no difference; a review of all ten studies called the record mixed.6, 7, 8, 9
Can I take collagen and creatine in the same coffee?
Yes. Collagen peptides dissolve in hot or cold liquid, creatine settles unless you stir, and no interaction has been reported. The collagen side is in can I add collagen to my coffee.
How long can creatine sit in a drink?
The stability figures are for three days at room temperature: 4% at pH 5.5, 21% at juice acidity.1 Mixed in the morning and drunk by lunch is well inside that data; minutes have not been measured.
Is pre-mixed creatine in a bottle a problem?
It depends on the formulation and storage. In a 2003 study, an effervescent creatine citrate solution lost 90% of its creatine in 45 days at room temperature and 80% refrigerated.12 A ready-to-drink product is tested for the shelf life its label states; a drink you mix yourself and leave in the fridge is not.
