TL;DR
Take 3g of creatine at whatever time of day you will remember, every day, including rest days. Before or after training makes little difference; consistency is what fills your muscle stores.
Key takeaways
- 3g a day is the amount the authorised performance claim is based on.
- Before or after training: studies find small differences at most.
- Morning or night both work. Pick the one you will not forget.
- Rest days count. Take it then too.
When to take creatine is one of the most searched creatine questions in the UK, and it has a short answer: whenever you will actually take it. Creatine does not work like caffeine. It does not kick in an hour later. It builds up in your muscles over weeks, so the time of day matters far less than taking it every day.
That is the headline. Below is the detail, so you can pick a time that fits your routine and stop thinking about it.
How creatine works (and why timing matters less than you think)
Your muscles store creatine as phosphocreatine. They use it for short, hard efforts: a heavy set, a sprint, a scramble on the mat. Taking creatine every day tops those stores up. Once they are full, they stay full as long as you keep taking it.
Creatine increases physical performance in successive bursts of short-term, high intensity exercise. The beneficial effect is obtained with a daily intake of 3g of creatine.
Because the effect comes from full stores rather than a single dose, the question is not "when", it is "how often". The answer to that is every day.
Creatine before or after a workout?
This is where most of the debate sits. A 2013 study by Antonio and Ciccone gave trained men 5g of creatine either just before or just after training for four weeks. The post-workout group did slightly better on some measures, but the differences were small and the study was small. Later reviews reach the same conclusion: taking creatine close to training, either side of it, is reasonable, and neither option is clearly better.
If you train in the evening and like a shake afterwards, put your creatine in the shake. If you train first thing and have a drink before you leave, put it in that. Both are fine.
Should you take creatine in the morning or at night?
Either. Creatine has no stimulant effect, so taking it at night will not keep you awake. The exception is a product that contains caffeine, such as Creatine Plus Energy, which has 80mg of caffeine per serving. Take that one earlier in the day.
A simple rule: attach creatine to something you already do every day. Breakfast, your first coffee, the protein shake after training. Habits stick when they piggyback on other habits.
Do you take creatine on rest days?
Yes. Rest days are part of the plan, not a break from it. Skipping creatine on non-training days slowly lowers your stores, and the point is to keep them full. Take your usual 3g with breakfast or any drink.
Do you need a loading phase?
No. A loading phase is about 20g a day, split into four doses, for five to seven days. It fills your stores in about a week (Hultman et al., 1996). Taking 3g a day gets you to the same place in roughly three to four weeks. Loading is faster, not better, and large single doses are more likely to upset your stomach. Our creatine dosing guide covers this in more detail.
What to take it with
Creatine monohydrate mixes into water, juice, a protein shake or a smoothie. Some studies suggest taking it with carbohydrate or protein can help uptake slightly, which is another reason a post-training shake is a convenient slot. It is not essential.
- Powder: Creatine Monohydrate is 3g a scoop. A 300g tub is 100 servings, so about 9p a day.
- No shaker: Creatine Gummies give you 3g in three gummies.
- With electrolytes: Creatine Plus Electrolytes is 3g of creatine plus a 175mg electrolyte complex, 112 servings a tub.
Missed a day?
Carry on with your normal dose the next day. Do not double up. Muscle creatine stores fall slowly, over around four to six weeks, so one missed day makes very little difference.
Common questions about creatine timing
Is it better to take creatine before or after a workout?
Studies find little difference. If anything, a few small studies lean slightly towards after training. Pick whichever fits your routine and take it every day.
Can I take creatine at night?
Yes. Creatine monohydrate is not a stimulant and should not affect sleep. Only products with added caffeine are better taken earlier in the day.
Should I take creatine on an empty stomach?
You can, but some people find it sits better with food or a shake. If your stomach feels unsettled, take it with a meal.
How long does creatine take to work?
At 3g a day, your muscle stores fill over roughly three to four weeks. That is why daily use matters more than the time on the clock.
Can I take creatine with coffee?
Yes, most people can. One small 1996 study suggested very high caffeine intakes might blunt creatine during a high-dose loading phase. Later research has not consistently found this, and a 2015 review concluded the two are unlikely to work against each other at normal intakes.
The bottom line on creatine timing
The best time to take creatine is the time you won't forget. Before or after training, morning or night, the difference is small. Taking 3g every day, including rest days, is what counts.
