How much creatine should you take a day?
This free calculator works out how many grams of creatine monohydrate to take each day from your body weight, goal, training, and diet — then converts that into level scoops or capsules, with an optional loading phase. Move the weight slider and your answer updates instantly, with built-in safety checks.

Creatine dosage is one of the few supplement questions with a genuinely settled answer: most adults take 3 to 5 grams of creatine monohydrate a day, every day. What changes from person to person is the exact number inside that range, whether a loading phase is worth doing, and which format makes that dose practical to actually swallow.
Quick answer: The standard creatine dose is 3 to 5 grams a day of creatine monohydrate, taken every day whether you train or not. Larger bodies and heavy trainers sit at the top of that range or slightly above it. An optional loading phase of about 0.3 grams per kilogram of body weight — roughly 20 to 25 grams a day split into four doses — fills your muscle stores in 5 to 7 days instead of 3 to 4 weeks.
Key Takeaways
- 3 to 5 g a day of creatine monohydrate is the dose used in most published trials.
- Loading is optional. It reaches the same end point faster, not a higher one.
- Loading math is 0.3 g per kg of body weight, split into 4 doses, for 5 to 7 days.
- Vegetarians and vegans start lower, so they tend to gain the most from supplementing.
- Timing does not matter much — taking it every single day does.
- A 20 g loading dose is 4 scoops of powder but 20 capsules, which is why format matters.
How the calculator works
The tool starts from the dose range used across the research literature, then adjusts inside it. Body weight is the main lever, because creatine is stored in skeletal muscle and a larger body holds more of it. On top of that it adds a gram for people who eat little or no meat, since a mixed diet already supplies 1 to 2 grams a day and a plant-based diet supplies almost none.[1]ISSN Position Stand: Safety and Efficacy of Creatine Supplementation in Exercise, Sport, and Medicine — J Int Soc Sports Nutr (2017) View source
If you ask for a loading phase, it uses the body-weight formula from the sports nutrition literature: about 0.3 grams per kilogram per day, divided into four smaller doses, for 5 to 7 days.[2]Creatine: how and when do I use it — Australian Sports Commission / AIS View source Splitting it matters, because a single large dose is the main reason people report stomach upset. After that week you step down to the maintenance number, which is what holds your stores full.
| Body weight | Daily maintenance | Loading phase (optional) | Days to full stores |
|---|---|---|---|
| Under 120 lb (55 kg) | 3 g | About 16 g a day, in 4 doses | 5–7 with loading |
| 120–200 lb (55–90 kg) | 5 g | About 17–27 g a day, in 4 doses | 5–7 with loading |
| Over 200 lb (90 kg) | 5–10 g | 25 g a day, in 4 doses | 5–7 with loading |
| Any weight, no loading | 3–5 g | Skip it | 21–28 |
Maintenance figures follow the 3 to 5 g range in the ISSN position stand, which also notes that larger athletes may need 5 to 10 g a day to hold saturation. Loading follows the 0.3 g per kg protocol used in sports nutrition practice.[3]Naderi et al.

Powder or capsules for your dose
Format is not a matter of taste once you look at the numbers. Creatine capsules hold 1 gram each, so a 5 gram dose is 5 capsules and a 20 gram loading day is 20 capsules. The same amounts in powder are one level scoop and four scoops. That is why the calculator pushes anyone loading, or anyone above 5 grams a day, toward the powder.
| Factor | Powder (250 g tub) | Capsules (60 count) |
|---|---|---|
| Creatine per container | 250 g, 50 scoops of 5 g | 60 g, 60 capsules of 1000 mg |
| A 5 g dose | 1 level scoop | 5 capsules |
| A 20 g loading day | 4 scoops | 20 capsules, not practical |
| How long it lasts at 5 g a day | About 50 days | About 12 days |
| Best for | Value, loading, doses above 5 g | Travel, no mixing, no taste |

How much creatine should I take per day? +
For most adults the answer is 3 to 5 grams of creatine monohydrate a day, taken every day including rest days. Five grams is the amount used in the majority of clinical trials. Smaller people can sit at 3 g, and larger or heavily training people may need 5 to 10 g to hold their stores full.
How much creatine should I take for my weight? +
Under about 120 lb (55 kg), 3 g a day is enough. Between 120 and 200 lb, 5 g a day is the standard. Above 200 lb, the range moves to 5 to 10 g a day. For a loading phase the formula is body weight based: about 0.3 g per kilogram per day, split into 4 doses.
How much creatine for a 170 lb man? +
A 170 lb (77 kg) man sits squarely in the standard band, so 5 g a day of creatine monohydrate is the right maintenance dose. If he wants to load first, 0.3 g per kg works out to about 23 g a day, split into four roughly 6 g doses, for 5 to 7 days before dropping back to 5 g.
How much creatine should a 200 lb man take? +
At 200 lb (91 kg) you are at the top of the standard band, so 5 g a day is a solid maintenance dose and up to 7 to 8 g is reasonable if you train hard or carry a lot of muscle. A loading phase would be about 27 g a day, capped in practice around 25 g, split into four doses for 5 to 7 days.
Is 10 g of creatine a day too much? +
For a large, heavily training adult, 10 g a day is at the top of the range the ISSN describes for maintaining saturation, not an overdose. For an average-sized person it is simply more than the muscle can store, so the excess is excreted. Most people see no extra benefit above 5 g.
Is 10 g of creatine a day bad for your kidneys? +
In healthy adults, long-term studies have not shown kidney damage from standard creatine doses. Creatine does raise blood creatinine, which can look like a kidney problem on a lab report without being one. If you have existing kidney disease or reduced function, do not take creatine without your doctor clearing it first.
How much creatine should I take the first week? +
You have two valid options. Skip loading and take 3 to 5 g a day from day one, reaching full stores in 3 to 4 weeks. Or load with about 0.3 g per kg a day, split into 4 doses, for 5 to 7 days, then step down to the maintenance dose. Both end at the same place.
Do I actually need a loading phase? +
No. Loading only changes how quickly your muscles fill, not how full they end up. It is useful if you have a competition or a training block starting in a week. If you have no deadline, the steady 3 to 5 g approach is simpler, gentler on the stomach, and uses less product.
How much creatine should I take to build muscle? +
The same 3 to 5 g a day. Creatine does not build muscle on its own; it lets you push a little more volume in resistance training, and that extra work is what drives growth. Taking more than the dose your muscle can store will not speed it up.
How much creatine should I take a day for cognitive function? +
Brain creatine is slower to respond than muscle, and cognitive studies have generally used doses at or above 5 g a day, with some using considerably more over several weeks. A practical starting point is 5 g daily, taken consistently, and giving it at least a month before judging the effect.
How much creatine should women take? +
The dosing logic is the same and scales with body weight, so many women land at 3 to 5 g a day rather than the 5 g default. Creatine does not cause bulk in women; the small early weight change is water drawn into muscle, not fat, and it settles.
What are the signs creatine is working? +
The usual first sign is being able to get an extra rep or two at the same weight, or recovering faster between hard sets. A small weight increase of 1 to 3 lb in the first week or two is normal and reflects water inside muscle. Expect to notice something within 2 to 4 weeks.
Why did I gain weight after starting creatine? +
Creatine pulls water into your muscle cells, so the scale can move 1 to 4 lb in the first week or two, and a loading phase exaggerates it. That is water inside muscle, not fat. If you have gained closer to 10 lb, water alone does not explain it — look at how your eating changed when you started training harder.
Should I take creatine capsules or powder? +
Powder is better value and far more practical for doses above 5 g or for a loading week, since one level scoop equals 5 capsules. Capsules win when you travel, dislike mixing, or want an exact count with no scale. Both deliver identical creatine monohydrate.
Do I need to cycle off creatine? +
No. There is no evidence that continuous use stops working or that your body stops making its own creatine permanently. If you stop, your muscle stores simply drift back to baseline over about four to six weeks. Daily use is the protocol the research supports.
