How Much Creatine Per Day?
The short answer is 3–5 grams. Here is where that number comes from, when body weight matters, what to buy, and when to take it.

The standard dose: 3–5 g a day
The International Society of Sports Nutrition says that once your muscles are full, 3–5 g a day keeps them full, while some larger athletes may need 5–10 g a day (ISSN position stand, 2017). The NIH Office of Dietary Supplements describes the typical adult protocol, “regardless of sex or body size”, as a loading phase of 20 g a day followed by 3–5 g a day, or simply 3–6 g a day without loading for 3–4 weeks (NIH Office of Dietary Supplements). A 2021 review by creatine researchers concluded that a loading phase is not required and that 3–5 g a day works (Antonio et al., 2021).
Creatine dosage by body weight
If you prefer a dose that scales with you, the NIH gives 0.03–0.1 g per kg of body weight a day without loading (NIH Office of Dietary Supplements). Loading is usually 0.3 g per kg a day (ISSN position stand, 2017). Here is what that means at common weights:
| Weight | In kg | Daily dose | 0.03–0.1 g/kg | Loading, per day |
|---|---|---|---|---|
| 100 lbs | 45.4 kg | 3–5 g | 1.4–4.5 g | 13.6 g |
| 120 lbs | 54.4 kg | 3–5 g | 1.6–5.4 g | 16.3 g |
| 140 lbs | 63.5 kg | 3–5 g | 1.9–6.4 g | 19.1 g |
| 160 lbs | 72.6 kg | 3–5 g | 2.2–7.3 g | 21.8 g |
| 180 lbs | 81.6 kg | 3–5 g | 2.4–8.2 g | 24.5 g |
| 200 lbs | 90.7 kg | 3–5 g | 2.7–9.1 g | 27.2 g |
| 220 lbs | 99.8 kg | 3–5 g | 3.0–10.0 g | 29.9 g |
| 250 lbs | 113.4 kg | 3–5 g | 3.4–11.3 g | 34.0 g |
| 280 lbs | 127.0 kg | 3–5 g | 3.8–12.7 g | 38.1 g |
Loading = 0.3 g/kg a day for 5–7 days, split into 4 doses, then 3–5 g a day. Values rounded to 0.1 g.
When to take creatine
Creatine is not a pre-workout stimulant; it works by slowly filling your muscle stores. That is why the most important thing is to take it every day, including rest days. Before or after training, morning or evening: pick the time you will remember. Taking it with a meal or shake is easy, and splitting a loading dose into four portions makes it gentler on the stomach.
How to take it
- Mix it in a drink: water, juice, milk, coffee or a protein shake. It dissolves better in warm liquid, which is why early studies used hot tea, but that does not change how much you absorb (Antonio et al., 2021).
- Drink it soon: creatine powder is stable for years, but in liquid it slowly turns into creatinine, so do not mix a week’s worth in advance (Antonio et al., 2021).
- Measure it once: a common label serving is 5 g = 1 rounded teaspoon. Weigh one scoop on a kitchen scale to know what yours holds.
Which type of creatine is best?
Creatine monohydrate. It is the form used in most studies and is 88% creatine by weight (NIH Office of Dietary Supplements). A review of newer forms found little to no evidence that any of them are more effective or safer (Jäger et al., 2011). The ISSN team adds that there are no peer-reviewed studies showing that creatine salts, creatine ethyl ester, buffered creatine, creatine nitrate or the tiny amounts in creatine drinks raise muscle creatine more than monohydrate (Antonio et al., 2021). The NIH notes that the other forms are usually more expensive (NIH Office of Dietary Supplements). With gummies and capsules, check how many grams of creatine you actually get per serving.
How much creatine is in food?
Your liver and kidneys make about 1 g a day. Beef has about 2 g per pound, pork about 2.3 g and salmon about 2 g (NIH Office of Dietary Supplements). Getting 3–5 g from food alone would mean eating 1.5 to 2.5 pounds of meat or fish every day. Vegetarians have lower muscle creatine and may respond more to a supplement (NIH Office of Dietary Supplements).
What about creatine for the brain?
Some research looks at creatine for memory and thinking, and some reviewers suggest higher doses for the brain than for muscle (Smith-Ryan et al., 2021). The evidence is still early and mixed. We cover it honestly in creatine for older adults.

Frequently asked questions
How much creatine should I take a day?
For most adults, 3–5 grams a day. That covers men and women of any body size, according to the NIH Office of Dietary Supplements and the ISSN. Larger athletes in hard training may need 5–10 g a day.
Is 5 g of creatine a day enough?
Yes, for most people. 5 g a day is at the top of the standard 3–5 g range and fills muscle stores in about 3–4 weeks without a loading phase.
Is 10 g of creatine a day too much?
It is more than most people need, but it is not considered dangerous for healthy adults: the ISSN reports doses up to 30 g a day for 5 years were safe and well tolerated in healthy people. Extra creatine beyond what your muscles can store is simply excreted. If you have kidney disease, ask your doctor before taking any amount.
Should I take creatine on rest days?
Yes. Creatine works by keeping your muscle stores full, so take it every day, including rest days.
Can I get enough creatine from food?
Partly. Beef and salmon contain about 2 g per pound, and your body makes about 1 g a day. A normal diet with 1–2 g a day leaves muscle stores about 60–80% full, so a supplement is the practical way to fill them.
Do I need to cycle creatine?
No research shows that you need to cycle off. Daily use for months and years (up to 5 years in studies reviewed by the ISSN) has been well tolerated in healthy people. If you stop, your muscle creatine drifts back to its normal level over about a month.
