Three to five grams a day, every day. That is the whole answer for most people. If you want to be precise, the maintenance dose is about 0.03 g per kilogram of bodyweight, which is 2 g for a 60 kg person and 3 g for a 100 kg person. Five grams covers almost everyone with room to spare, which is why it became the default. New to it? Start with what creatine does.
- Standard dose: 3 to 5 g of creatine monohydrate daily
- By bodyweight: about 0.03 g per kg per day to keep muscle stores full
- Loading (optional): 20 g a day in four doses, for 5 to 7 days
- Time to full stores: about 6 days with loading, about 28 days without
- Above saturation: extra creatine is excreted, not stored
Why is 5 g the standard dose?
Because of a study from 1996, and because it is a round number that works for nearly everybody.
Eric Hultman's team gave 31 men different creatine protocols and measured what happened inside the muscle. Twenty grams a day for six days raised total muscle creatine by about 20%. Then 2 g a day held it there for another month. Separately, 3 g (grams) a day with no loading at all reached the same 20% increase in 28 days instead of six; 3 g a day is also the register's condition for the authorised performance wording.1
Every dosing recommendation you have read comes from that study and the work that followed it. Five grams became standard because it exceeds what almost anyone needs, costs pennies, and removes the need to think about it.2
Evidence: strong. The saturation ceiling and the two routes to it have been replicated repeatedly since 1996.
How much creatine should you take for your bodyweight?
Creatine is stored in muscle, so bigger people with more muscle need slightly more. The usual scaling is 0.03 g per kilogram per day for maintenance and 0.3 g per kilogram per day during a loading phase.
For a 70 kg person, that is 2.1 g a day to maintain full stores, or 21 g a day for five to seven days if loading. In practice, 3 to 5 g a day is the sensible number, because it covers missed days, hard training weeks and an imprecise scoop.
| Bodyweight | Calculated maintenance | Loading dose (if used) | Practical daily dose |
|---|---|---|---|
| 50 kg | 1.5 g | 15 g | 3 g |
| 60 kg | 1.8 g | 18 g | 3 g |
| 70 kg | 2.1 g | 21 g | 3 to 5 g |
| 80 kg | 2.4 g | 24 g | 5 g |
| 90 kg | 2.7 g | 27 g | 5 g |
| 100 kg | 3.0 g | 30 g | 5 g |
| 120 kg | 3.6 g | 36 g | 5 to 7 g |
Notice how flat the practical column is: a 50 kg person and a 100 kg person are separated by about 1.5 g a day, which is why the idea of a special lower dose for women does not hold up.
Is 10 g of creatine a day too much?
For muscle stores, yes: anything above saturation is excreted. But there are two dosing conventions in the research, and almost nobody explains the difference.
The muscle convention, 0.03 g per kg per day, comes from the saturation studies. It answers "what is the minimum that keeps muscle stores full?" and gives 2 to 4 g a day for most adults.
The ageing and bone convention, 0.10 to 0.14 g per kg per day, comes from trials in older adults and the bone research, which used much higher relative doses. For a 70 kg person that is 7 to 10 g a day. Researchers chose those doses partly because older adults may absorb creatine less efficiently and start with less muscle.3
Both are defensible and answer different questions: a healthy 30 year old wanting the performance effect is covered by the lower convention; someone over 60 following the ageing research is drawing on trials that used considerably more. Kidneys and blood tests are covered here.
Should you do a loading phase?
Only if you have a deadline.
Loading means 20 g a day, split into four 5 g doses, for five to seven days. It fills muscle stores in about six days. Not loading means 3 to 5 g a day and reaching the same place in about four weeks. The end result is identical. Loading costs more creatine in the first month, raises the chance of an upset stomach, and makes the early water weight more noticeable.1, 4 A meal alongside any dose is practical advice, not a benefit. How much weight creatine adds, and why it is not fat, is here.
If you have a race, a meet or a fixture inside three weeks, load. Otherwise the only thing it buys you is three weeks. The full case for and against loading, with the protocol if you do, is here.
Does taking more creatine work better?
No. Muscle creatine has a ceiling of roughly 160 mmol per kilogram of dry muscle, and most people start around 120. Supplementation moves you from one to the other and then stops mattering.1
A 2025 meta-analysis that compared trials by dose found that low-to-moderate doses were not outperformed by high doses for strength gains. That comparison is between different trials rather than within one, so it is not proof that less is more, but it gives no support to taking more.5
Does the dose change for women?
No. Dose scales with bodyweight, not sex, and a woman of 60 kg needs the same as a man of 60 kg. If anything the evidence points the other way: in postmenopausal women, trials using 3 g a day or less without training showed no measurable effect, while effects appeared at 5 g a day or more combined with resistance training.6, 7 Creatine for women is covered here.
How much water should you drink with creatine?
Creatine does not change how much you need to drink; the NHS guide of 6 to 8 cups or glasses of fluid a day stands, more in heat or long sessions.8 The trials behind that answer, and why you may pee more, are in the guide to whether creatine dehydrates you.
Is your scoop actually 5 g?
Often not. Scoop volumes vary between products, and so does powder density, so a scoop labelled 5 g can deliver anywhere from about 3.5 g to over 6 g. Weigh one level scoop on kitchen scales once and mark the fill level with a permanent marker. The beginner's routine is here. Pre-dosed formats such as gummies or tablets avoid the problem; check the creatine content per piece and the number of pieces that make a serving. What to check in a gummy is here.
Who should check with a GP or pharmacist first?
- Anyone with a diagnosed kidney condition or reduced kidney function.
- Anyone pregnant, trying to conceive, or breastfeeding.
- Anyone taking medication that affects the kidneys, including long-term anti-inflammatory painkillers or diuretics.
- Anyone under 18.
- Anyone managing a condition with medication.
Creatine is not known to be harmful in these situations. The evidence is thinner, and an individual decision beats a general article. Creatine also raises blood creatinine, which is the marker used in kidney-function tests, so tell your doctor you take it before any blood test.9
What we don't know
- Whether older adults need higher relative doses, or whether the trials simply used them. No head-to-head comparison exists.
- Individual variation. Roughly 20 to 30% of people respond minimally. Diet and muscle fibre type predict it in part, not reliably enough to personalise a dose in advance.
- Long-term dosing above 5 g. Most safety data covers 3 to 5 g.
Frequently asked questions
How many teaspoons is 5 g of creatine?
Teaspoons are not a reliable measure for creatine: powders differ in particle size and how they settle, and no published density figure exists for the forms sold. Use the scoop supplied or weigh a serving once on kitchen scales; a pre-dosed format removes the question.
What happens if you take too much creatine?
Above saturation the extra leaves in urine.1 In 59 footballers a single 10 g serving doubled diarrhoea compared with 5 g twice a day (55.6% versus 28.6%), so the practical ceiling is 5 g (grams) per serving, and 2.5 g twice a day (when to take creatine) is a reasonable split if even that unsettles you.10 Taking more does not work faster once stores are full; the 10 g section above has the detail.
What happens if I miss a dose?
Very little. Muscle stores decline slowly, taking about four weeks to return to baseline with no supplementation at all. Missing a day is invisible. After two weeks off, resume your normal dose; there is no need to reload, and no need to cycle it either: what happens when you stop covers breaks.1
How much creatine for a 70 kg person?
3 to 5 g a day, as for most adults. A 0.03 g per kilogram maintenance figure gives about 2 g for 70 kg, which is the floor; 3 to 5 g covers everyone up to a large frame.
How much creatine should I take at 60 or older?
3 to 5 g a day with resistance exercise; trials in older adults went up to 0.14 g per kilogram, about 10 g at 70 kg.3 Check with your GP first if you have kidney disease or take several medicines.
