Can you put creatine in coffee? Yes. Creatine monohydrate dissolves better in hot coffee than in cold water, and it stays effective as long as you drink it within the hour rather than leaving it to sit for days. The one real question is caffeine. One early study found that high daily caffeine during a creatine loading phase cancelled creatine’s performance boost, but later studies mostly haven’t seen that. For most people taking 3 to 5 grams a day with a normal cup or two of coffee, mixing them is fine.
This guide covers what the caffeine studies actually found, why hot coffee works better than cold, whether creatine contains caffeine, how to take creatine with coffee, and what else not to mix with creatine.
Does Caffeine Cancel Out Creatine?
Probably not at normal intakes. Here’s the research in the order it was published:
| Study | What they did | What they found |
|---|---|---|
| Vandenberghe 1996 (9 men) | 6 days of high-dose creatine loading (0.5 g per kg a day), with or without caffeine (5 mg per kg a day, about 350 mg for a 70 kg person) | Creatine alone raised strength in repeated contractions by 10–23%. With caffeine, the strength gain disappeared, although muscle creatine stores still rose [1] |
| Trexler 2016 (54 active men) | 5 days of creatine loading (20 g a day) alone, with 300 mg of caffeine, or with coffee containing about 300 mg of caffeine | No difference between the groups in strength or sprint power. Four people reported mild stomach upset with creatine plus caffeine powder [2] |
| Elosegui 2022, systematic review (10 studies) | Compared the studies that combined both supplements | Creatine loading didn’t blunt caffeine’s short-term boost. When both were taken daily during loading, 2 studies found interference, 3 found none and 1 found the two worked better together [3] |
The fair conclusion: the only clear problem appeared with a high-dose loading phase plus a lot of caffeine every day. The review’s authors suggested the two may work against each other on muscle relaxation, and that stomach upset from taking both may play a part [3]. If you skip loading and take a steady 3 to 5 g a day, there’s little evidence your morning coffee gets in the way. If you want to be cautious, keep caffeine moderate during the first week, or take creatine at a different time of day from your coffee.
Can You Put Creatine in Hot Coffee?
Yes, and hot coffee is actually better than cold drinks for dissolving it. Creatine dissolves much more easily as the temperature rises. One litre of water dissolves about 14 g of creatine at room temperature (20 °C), 34 g at 50 °C and 45 g at 60 °C [4].
In practice, a 250 ml (8 oz) cup of hot coffee can dissolve a 5 g dose several times over. The same amount of room-temperature liquid dissolves only about 3.5 g, and ice-cold liquid (about 6 g per litre at 4 °C) only about 1.5 g, so in iced coffee some powder stays gritty at the bottom. If you use cold drinks, stir well and drink the last sip, where the undissolved creatine settles.
Does heat destroy creatine? Not in the time it takes to drink a coffee. Creatine monohydrate powder is very stable, with no measurable breakdown over years even at high storage temperatures [4]. Once it’s dissolved, it slowly turns into creatinine, a waste product your body can’t use. That happens faster in acidic drinks. After 3 days at room temperature, about 4% had broken down at pH 5.5, 12% at pH 4.5 and 21% at pH 3.5 [4]. Those losses build up over days, not minutes. Just don’t make a big batch of creatine coffee and keep it in the fridge all week.
Does Creatine Have Caffeine?
No. Creatine monohydrate is creatine bound to a water molecule. It contains no caffeine and isn’t a stimulant, so it won’t keep you awake or give you an energy buzz. What often does contain caffeine is pre-workout supplements, many of which combine creatine with a sizeable dose of caffeine. If your “creatine” makes you feel wired, check the label: you may be taking a pre-workout. Here’s what to know about pre-workout side effects.
How to Take Creatine With Coffee
- Dose: 3 to 5 g of creatine monohydrate a day is the standard maintenance dose [5]. See how much creatine per day for doses by body weight.
- Mixing: stir it into hot coffee until it disappears. Plain creatine monohydrate is close to tasteless; if you notice a slight grittiness, add it before milk so it dissolves in the hottest liquid.
- Milk, cream and protein: all fine. Taking creatine with a meal or with protein and carbohydrate may help uptake a little [5].
- Timing: any time of day works. Taking it every day matters more than when.
- Caffeine: keep your total within the FDA’s guide of about 400 mg a day for most healthy adults, roughly two to three 12 oz cups of coffee [6].
- Loading phase: you don’t need one. If you do load (around 20 g a day for 5 to 7 days), consider keeping caffeine low that week.
Creatine draws water into your muscles, so drink normally through the day. Coffee counts toward your fluids. More on that in how much water to drink on creatine.

Who Should Take Creatine and Coffee Separately?
- People with sensitive stomachs: stomach upset is the most common complaint with the combination [2]. Try creatine with food instead.
- Heavy caffeine users: if you drink several strong coffees or take caffeine pills or pre-workouts daily, taking creatine at a different time is an easy precaution.
- Anyone doing a loading phase: this is the situation where interference was seen.
What Not to Mix With Creatine
Creatine has few true interactions. The things worth knowing:
- Drinks left standing: mix creatine just before you drink it. In acidic drinks like fruit juice, it breaks down faster the longer it sits [4].
- Heavy alcohol use: there’s no direct harmful interaction, but alcohol works against the training, recovery and sleep that creatine is meant to support.
- Kidney concerns: creatine is considered safe for healthy people [5]. If you have kidney disease, or regularly take medicines that can affect the kidneys (such as anti-inflammatory painkillers or diuretics), ask your doctor first.
- Blood tests: creatine raises blood creatinine, which labs use as a kidney marker. In the 2016 study, creatinine rose in every creatine group [2]. Tell your doctor you take creatine so a normal rise isn’t mistaken for a kidney problem.

Frequently Asked Questions
Can you put creatine in coffee?
Yes. Creatine monohydrate dissolves well in hot coffee and stays effective if you drink it soon after mixing. Most studies found caffeine doesn’t cancel creatine’s benefits at normal intakes. The one exception was high daily caffeine during a high-dose loading phase, so skip loading or keep caffeine moderate that week.
Can you put creatine in hot coffee?
Yes, and it dissolves better hot. Water at 60 °C dissolves about three times as much creatine as room-temperature water, so a 5 g dose disappears completely in a hot cup. A few minutes of heat doesn’t destroy it. Creatine only breaks down noticeably when it sits in liquid for days.
Does caffeine cancel out creatine?
Usually not. A 1996 study found that about 350 mg of caffeine a day during a high-dose loading phase cancelled creatine’s strength boost. But a larger 2016 study found no difference with coffee or caffeine, and a 2022 review of 10 studies found mixed results. At 3 to 5 g a day with normal coffee intake, there’s little evidence of a problem.
Does creatine have caffeine in it?
No. Creatine monohydrate contains no caffeine and isn’t a stimulant, so it won’t affect your sleep or give you an energy kick. Many pre-workout supplements contain both creatine and caffeine, so if a product makes you feel wired, check whether it’s a pre-workout rather than plain creatine.
Can you put creatine in coffee with milk?
Yes. Milk, cream or a protein coffee are all fine, and taking creatine alongside protein or carbohydrate may help absorption slightly. For the smoothest mix, stir the creatine into the hot coffee first, then add the milk.
Can you mix creatine with tea?
Yes. The same rules apply as for coffee: it dissolves best in hot tea, should be drunk soon after mixing, and tea’s caffeine is generally lower than coffee’s. Herbal teas without caffeine avoid the caffeine question entirely.
