When to take Creatine
Also known as Creatine monohydrate
Any time; consistency matters more than timing. A research review found no solid evidence that taking creatine before or after a workout changes results, so take your daily amount at a time you will remember, ideally with a meal or snack.

- Any time; consistency matters more than timing.
- A few small studies hint that taking creatine after exercise may help more than before, but the results are mixed and not solid.
- Taking creatine with carbohydrate, or carbohydrate plus protein, has been linked to more creatine being kept in the muscles.
- Creatine works by filling up your muscle stores over days to weeks, so taking it every day matters more than the hour.
- If you stop, muscle creatine stores usually take about 4–6 weeks to drop back to where they started.
Check with your doctor first if…
- Weight gain: creatine often adds 1–2 kg of body weight in the first month, mostly water held in the muscles.
- Stomach upset, nausea, diarrhea and muscle cramps have been reported, though not consistently; drinking enough fluid may help.
- Kidney problems: some experts suggest people with existing kidney disease talk to their doctor before using creatine.
- Endurance sports: creatine is of little value for long-distance running or swimming, and the extra weight may slow you down.
- Pregnancy or breastfeeding: research on creatine in pregnancy is still early, so ask your doctor first.
Amounts studied
Studied: a 5–7 day loading phase of 20 g/day (four 5 g doses), then 3–5 g/day to maintain. Without loading, about 3–6 g/day fills muscle stores more slowly, over 3–4 weeks. Creatine monohydrate is the most studied form. There is no official RDA or UL.
Follow the serving size on your product’s label.
What the research says
| Area | Evidence | Summary |
|---|---|---|
| Exercise performance | Strong | Creatine is one of the most studied supplements. Trials in men and women show it supports strength, power and repeated short bursts of hard effort, like sprints and lifting.[1] |
| Muscle strength | Moderate | A 2026 review of 11 trials in adults 60 and older found that creatine plus strength training gave a small extra gain in strength. Effects on muscle size and daily function were unclear.[4] |
| Exercise performance in women | Limited | A 2026 review of studies in women found small possible gains in strength, power and lean mass. Certainty was low because the studies were small and varied.[5] |
Questions
Should I take creatine before or after a workout?
There is no clear answer yet. A 2021 review found only a few studies with mixed results and said timing around training should not be a real concern for now. Taking it every day matters most.
How long does creatine take to work?
With a loading phase of about 20 g a day for 5–7 days, muscle stores fill in about a week. Taking 3–5 g a day without loading fills them more slowly, over about 3–4 weeks.
Can I take creatine every day?
Yes, daily use is how it has been studied. NIH says creatine is considered safe for short-term use by healthy adults, and evidence shows several years of use is safe.
Does creatine make you gain weight?
Often, yes. Studies show about 1–2 kg of weight gain in the first month, mostly water held in the muscles. Weight gain is the only side effect that has been reported consistently.
Does creatine work for women?
Benefits have been reported in women, but most studies were done in men, and some suggest women gain less strength or muscle. A 2026 review of studies in women found small benefits with low certainty.
