How much creatine per day? For most adults, 3–5 grams of creatine monohydrate once a day is enough to fill your muscles’ creatine stores and keep them full. Larger, heavily training athletes may need 5–10 grams. A loading phase of about 20 grams a day for 5–7 days is optional. It fills your stores faster, but you end up at the same place.

These doses follow the International Society of Sports Nutrition (ISSN) position stand on creatine, the most widely cited summary of the research [1]. All amounts are for creatine monohydrate.
| Who | Daily dose | Notes |
|---|---|---|
| Most adults | 3–5 g | Once a day, every day, including rest days |
| Lighter adults (under ~60 kg / 130 lb) | 3 g | 5 g is also fine, just not necessary |
| Larger athletes in hard training | 5–10 g | The ISSN notes some studies suggest larger athletes need this much to keep stores full |
| Loading phase (optional) | ~20 g (0.3 g/kg) for 5–7 days | Split into 4 servings of about 5 g, then drop to 3–5 g |
| Women | 3–5 g | The same research-based range. Lighter women can use 3 g |
| Vegetarians and vegans | 3–5 g | Start with lower stores, so they often notice more benefit |
More isn’t better once your muscles are full. Beyond what they can store, extra creatine is broken down and excreted, and larger single doses are more likely to upset your stomach.
How Much Creatine Per Day by Body Weight
Most research uses a flat 3–5 g a day regardless of weight, and that works for most people. Body weight matters most during loading, which is usually dosed at about 0.3 g per kg of body weight a day [1]. The table uses the same method as our creatine calculator: about 0.05 g/kg for maintenance, kept within 3–5 g, and 0.3 g/kg for loading, capped at around 25 g.
| Body weight | Daily maintenance dose | Loading dose (5–7 days, optional) |
|---|---|---|
| 50 kg (110 lb) | 3 g | 15 g/day |
| 60 kg (132 lb) | 3 g | 18 g/day |
| 70 kg (154 lb) | 3.5 g | 21 g/day |
| 80 kg (176 lb) | 4 g | 24 g/day |
| 90 kg (198 lb) | 4.5 g | 25 g/day |
| 100 kg (220 lb) and up | 5 g (5–10 g if very muscular and training hard) | 25 g/day |
Creatine is stored in muscle, not fat. So a very muscular 90 kg athlete may benefit from the top of the range, while someone of the same weight with less muscle does fine on 3–5 g.
How Much Creatine Per Day to Build Muscle
The dose for building muscle is the same 3–5 g a day. What changes the result is training, not a bigger scoop. Creatine lets you do slightly more work in short, hard efforts (an extra rep or two, a bit more power), and over weeks of resistance training that extra work adds up to more strength and lean mass than training alone. Taken without training, it doesn’t build muscle on its own.
Expect the performance effect once your stores are full: within about a week if you load, or 3–4 weeks at 3–5 g a day. You may see a quick gain of a kilogram or so on the scale in the first week. That’s water drawn into your muscles, not fat.
Do You Need a Loading Phase?
No, but it works faster. In a classic study, men who took 20 g a day for 6 days raised their muscle creatine by about 20%. A separate group taking 3 g a day reached the same 20% increase after 28 days. A small maintenance dose (2 g a day in that study) kept the loaded levels up [2].
- Load if you want the effect within a week, for example before a competition. Take about 20 g a day (or 0.3 g/kg) split into four doses of about 5 g with meals, for 5–7 days, then drop to 3–5 g.
- Skip loading if you’re not in a hurry or you get stomach upset from larger doses. Take 3–5 g a day from day one and you’ll be fully saturated in 3–4 weeks.
Either way, the long-term dose is the same 3–5 g a day.
Do You Get Enough Creatine From Food?
Probably not enough to fill your stores. Creatine comes mainly from meat and fish. In US national survey data (NHANES 2017–2018), about 65% of adults ate less than 1 g of creatine a day from food, and that group averaged only about 0.5 g [3]. Even heavy meat eaters rarely get more than 1–2 g a day, which is why supplement doses are higher. Vegetarians and vegans get almost none from diet, so they start with lower stores and often see a larger effect from the same dose. Here’s what foods have creatine and how much is in each.
How to Take Your Daily Dose
- Timing: take it whenever you’ll remember. Studies comparing before and after workouts show small and inconsistent differences. Daily consistency matters far more than the time of day.
- All at once is fine for 3–5 g. Only loading doses need splitting.
- Rest days: take it every day. Creatine works by keeping stores topped up, not as a pre-workout.
- Measure it: a scoop or teaspoon holds roughly 3–5 g depending on the product, so check your scoop size against the label (or weigh it once) rather than guessing.
- With food: taking creatine with a meal containing carbohydrate or protein may help a little with uptake, and it’s easier on the stomach [1]. It also mixes well into hot drinks: here’s whether you can put creatine in coffee.
- Form: use plain creatine monohydrate. Almost all dosing research uses it, and it’s usually the cheapest. A basic tub of creatine monohydrate is all you need.

How Much Water Should You Drink on Creatine? →What Happens If You Stop Taking Creatine?
Your stores fall back gradually, not overnight. In the same loading study, muscle creatine returned to its starting level about 30 days after supplementation stopped [2]. Missing a day or two makes no real difference. If you stop completely, expect the extra water weight and the small performance boost to fade over roughly a month.

Frequently Asked Questions
Is 5 g of creatine enough to build muscle?
Yes, for most people. 5 g a day keeps muscle creatine stores full, and that’s the dose used in most studies showing extra strength and lean mass gains alongside resistance training. The training does the building. Creatine lets you do a little more work each session. Very large, muscular athletes may use up to 10 g.
Is 10 g of creatine a day too much?
For most people it’s more than needed, but it isn’t known to be harmful for healthy adults. Once your stores are full, the extra is broken down and excreted, and larger doses are more likely to cause stomach upset. The ISSN notes that larger athletes in hard training may need 5–10 g a day to keep stores full.
Can I take 20 g of creatine a day?
Short-term, yes. About 20 g a day, split into four 5 g doses for 5–7 days, is the standard loading phase. After that, drop to 3–5 g a day. Staying on 20 g long-term gives no extra benefit for healthy people, and very large doses such as 100 g a day should never be taken.
How much creatine should a woman take per day?
The same 3–5 g a day of creatine monohydrate. Research doses don’t differ by sex. Lighter women can use 3 g, and a loading phase is optional. Women tend to eat less meat and fish, so their natural intake is often lower, which makes a daily supplement relatively more useful. Take it every day, not only on training days.
Can I take all my creatine at once?
Yes. A 3–5 g maintenance dose can be taken in one go, at any time of day, with or without food. Only loading doses of around 20 g need splitting into several servings, because large single doses are more likely to cause bloating, cramping or diarrhoea. Taking it with a meal can make it easier on your stomach.
Does creatine HCl need a different dose?
Creatine HCl is often sold in smaller doses because it dissolves more easily, but there’s no good evidence that it works better than monohydrate, or that a smaller dose of HCl does the same job. Nearly all dosing research uses monohydrate, so the 3–5 g guidance applies to monohydrate specifically.
