How Much Creatine Per Day? A Guide to Daily Dosing

Most adults should take 3–5 grams of creatine monohydrate per day, every day. That is the maintenance range in the International Society of Sports Nutrition (ISSN) position stand, and taken from day one it fills your muscle creatine stores over about 3–4 weeks, no loading required.

Your body weight, how hard you train and whether you eat meat can nudge the picture, but they rarely change the answer.

So how much creatine per day is right for you? Below: the per-kilogram math with a body-weight table, what the muscle-building research shows, when big athletes go up to 10 g, and why one giant 10 g serving is not a shortcut. New to the supplement? Start with what creatine monohydrate does.

The short answer

3–5 g of creatine monohydrate a day is the standard daily dose. In a classic biopsy study, just 3 g a day raised muscle creatine about 20% in 28 days.
By body weight, that works out to roughly 0.03–0.1 g per kilogram a day. A 5 g serving lands inside that range for adults from about 55 to 110 kg.
Larger athletes in intense training may need 5–10 g a day, according to the ISSN.
Taking 10 g? Split it into two 5 g servings. In a 28-day trial in male soccer players, diarrhea was reported by 55.6% on one 10 g serving, 28.6% on two 5 g servings and 35.0% on placebo.
Consistency beats timing. Take it every day, training day or not.

How many grams of creatine a day do most adults use?

Take 3–5 g of creatine monohydrate a day. The ISSN position stand says that once your muscles are saturated, 3–5 g a day generally keeps them that way, and that the same 3–5 g taken from the start raises muscle creatine over a 3–4 week period.

The NIH Office of Dietary Supplements (ODS) lands in the same place: 3–5 g a day after an optional loading week, or about 3–6 g a day for 3–4 weeks if you skip loading.

The muscle-biopsy data behind those numbers is old and refreshingly tidy. In Hultman and colleagues' 1996 study of 31 men, 3 g a day raised muscle total creatine by about 20% over 28 days, the same rise a 20 g-a-day loading week produced in 6 days.

After loading, just 2 g a day held the higher level for another 30 days. Without that daily top-up, levels were back to where they started about 30 days after stopping.

Why does such a small daily amount work? About 1–2% of the creatine in your muscles breaks down into creatinine every day, so your body needs to replace roughly 1–3 g a day depending on muscle mass, according to the ISSN.

A normal diet supplying 1–2 g a day leaves muscle stores only about 60–80% full. A steady 3–5 g closes that gap and keeps the tank topped up.

When you take it matters far less than whether you take it. A 2025 review by creatine researchers found pre- and post-workout creatine about equally effective and concluded that consistent intake during a training program is likely the most important variable. That includes taking creatine on rest days.

How much creatine for your body weight?

If you like a per-kilogram number, ODS puts the no-loading dose at about 0.03–0.1 g per kilogram of body weight a day. A 2021 review in the Journal of the International Society of Sports Nutrition gives the recommended dosages as 3–5 g a day or 0.1 g/kg a day.

Here is how many grams of creatine a day that comes to at a few common body weights.

Daily creatine by body weight at 0.03–0.1 g/kg (our arithmetic from the NIH ODS range, rounded; not a study result)
Body weight	Low end: 0.03 g/kg a day	High end: 0.1 g/kg a day
55 kg (121 lb)	1.7 g	5.5 g
70 kg (154 lb)	2.1 g	7.0 g
90 kg (198 lb)	2.7 g	9.0 g
110 kg (243 lb)	3.3 g	11.0 g

ODS pairs this per-kg range with about 3–6 g a day, so treat 3 g as the practical minimum even where the low column shows less. Two things stand out. First, a 5 g serving sits inside the range at every weight in the table, which is exactly why the fixed 3–5 g answer works for most people.

Second, the top of the range climbs with size. That matches the ISSN's note that larger athletes engaged in intense training may need 5–10 g a day to keep whole-body creatine stores full.

So the per-kilo math is a tool for the edges, not a reason to start counting decimals. If you are a big athlete in serious training and settle on more than 5 g, that is the context the research supports. Split it into separate servings through the day; the 10 g question below shows why.

How much creatine per day to build muscle?

The same 3–5 g a day, plus the training. The ISSN calls creatine monohydrate the most effective ergogenic supplement available to athletes for increasing high-intensity exercise capacity and lean body mass during training. The key phrase is during training: the lifting does the building, and creatine helps you do more of it.

The meta-analyses put numbers on the combination. A 2024 meta-analysis of resistance-training trials in adults under 50 (Wang and colleagues, mostly male participants) found creatine plus training added an average of 4.43 kg to upper-body strength across 21 studies and 11.35 kg to lower-body strength across 19 studies, compared with placebo plus training.

Those trials used 2–10 g a day after any loading phase, and dose (5 g a day or less versus more than 5 g) made no significant difference to upper-body gains. Higher-dose protocols showed only a trend toward bigger lower-body gains, which did not reach statistical significance (p = 0.068).

For body composition, a 2024 meta-analysis of 12 studies (Desai and colleagues, adults under 50) found creatine with resistance training increased lean body mass by 1.14 kg and lowered body-fat percentage by 0.88 points more than training alone.

The authors estimated that about 7 g a day would likely add roughly 1 kg of lean mass and trim about 0.7 kg of fat mass beyond what training alone delivers.

These are group averages from trials, not a forecast for your next 12 weeks. Part of the early scale change is water drawn into muscle: a loading week typically adds 1–3 kg of body mass, mostly water, according to the 2021 review.

Put together with Wang's dose comparison, Desai's 7 g figure is a pooled estimate rather than a new target: 3–5 g a day sits inside the doses these trials used and is the evidence-backed default, taken consistently with a program you actually follow.

Larger athletes in intense training are the group the ISSN says may need more. If a tub tells you more scoops mean more muscle, that is a sales plan, not a dosing plan.

Do you need a loading phase?

No. Loading, about 20 g a day split into four servings for 5–7 days, fills muscle stores faster, but 3–5 g a day reaches a similar level in about 3–4 weeks. Hultman's 3 g group hit roughly the same 20% rise by day 28, and the 2021 review states that because smaller daily doses (3–5 g or 0.1 g/kg) are effective, a loading phase is not required.

Does the dose change for women, older adults or vegetarians?

Not the number. ODS describes the typical adult protocol, a loading week followed by 3–5 g a day, as applying regardless of sex or body size, and none of these groups has its own established daily dose. What differs is how much research exists and how strongly people respond.

Women. There is no separate "women's dose." The strength data skew male: in the Wang meta-analysis, the female subgroup drew on only a few studies, and its average gains (1.54 kg upper body, 8.03 kg lower body) did not reach statistical significance.

That is a gap in the research, not evidence for a different number. Our guide to creatine for women walks through what the women-specific studies found.

Older adults. Age does not come with its own number either. The ISSN position stand reports creatine supplementation has been safe and well tolerated in groups ranging from infants to the elderly. In one year-long study of postmenopausal women described in the 2021 review, participants took 0.1 g/kg a day alongside supervised resistance training, the same per-kilo figure that review recommends for adults generally.

Vegetarians. Same dose, often a bigger response. Meat and fish supply dietary creatine (a pound of uncooked beef or salmon provides about 1–2 g, per the ISSN), so people who skip them tend to start lower.

In a 2003 randomized trial of 42 adults doing 8 weeks of resistance training, vegetarians began with less muscle creatine (117 vs 130 mmol/kg). On creatine, they gained more total creatine, phosphocreatine, lean tissue and total work than non-vegetarians taking creatine. ODS likewise notes vegetarians may respond more.

How many grams of creatine are in one scoop?

If you want the simplest way to land in the studied range, this is it. Infinite Labs Creatine Monohydrate gives you 5 g of creatine monohydrate in one scoop, right at the top of the 3–5 g daily range, with no scale, no math and no guessing. Creatine monohydrate is the form the ISSN calls the most extensively studied and clinically effective for supplements.

The powder is unflavored, so it fits into the drink you already use, and each container holds 60 servings: two months of daily scoops. Mix it when you are ready to drink it, since creatine is stable as a powder but can gradually convert to creatinine once it sits in liquid, per the ISSN.

One scoop a day, every day, following the directions on your container, is the whole routine.

One label note: the current label states that this product contains wheat, so check it if you avoid wheat. Certificates of analysis are available on request.

Quick answers

Is 10 g of creatine too much daily?

For healthy adults it falls within amounts studied safely, but for most people it is more than needed, and it should be split. The ISSN reports that supplementation up to 30 g a day for 5 years has been safe and well tolerated, and notes larger athletes in intense training may need 5–10 g a day.

For everyone else, 3–5 g already keeps full stores full. If you do take 10 g, split it: in a 28-day randomized trial in 59 male soccer players, diarrhea affected 55.6% of those taking one 10 g dose versus 28.6% taking two 5 g doses (and 35.0% on placebo); the split dose did not differ from placebo.

How much creatine should a 200 lb man take?

3–5 g a day covers most 200 lb men. At about 91 kg, the 0.03–0.1 g/kg range works out to roughly 2.7–9.1 g a day, and the standard dose sits comfortably inside it. A big athlete in hard, high-volume training is the case where the ISSN says 5–10 g a day may be needed; anything above 5 g goes down easier as separate servings.

Can I take creatine with lisinopril or spironolactone?

Ask the doctor who prescribed it, or your pharmacist, before you start. We cannot give drug-specific advice. Raise it especially if you have a kidney condition. Also mention creatine before any blood work: creatine breaks down into creatinine, blood creatinine is used as a proxy marker of kidney function, and creatine supplements can raise it, according to the 2021 review.

Our guide to creatine and your kidneys explains what that means for your results.

The takeaway

Take 3–5 g of creatine monohydrate every day, training day or rest day, and keep it going. That dose fills your muscles in about a month and keeps them full. Use the per-kilo math only at the edges: if you are a big athlete in serious training, 5–10 g a day split into servings is the upper maintenance range the ISSN describes, not a target for everyone.

For most people, one 5 g scoop a day is the entire plan. For the bigger picture, read what creatine monohydrate does.
