How Much Creatine Per Day? Creatine Dosage by Goal and Body Weight

Most adults take 3 to 5 g of creatine a day, every day, and that amount fills your muscle stores in about 3 to 4 weeks. A short loading phase of about 0.3 g per kg of body weight a day for 5 to 7 days gets you there faster, then you drop back to 3 to 5 g a day. This guide covers the standard dose, loading, a dose by body weight table, amounts used in research, how high is too high, and how to count grams in gummies and capsules.

It is educational, not medical advice.

Key Takeaways

• Standard dose: 3 to 5 g a day fills muscle creatine stores over about 3 to 4 weeks without loading (Kreider et al., 2017).
• Loading is optional: 20 g a day for 6 days and 3 g a day for 28 days both raised muscle creatine by about 20 percent (Hultman et al., 1996).
• Split big amounts: a single 10 g dose caused diarrhea about twice as often as two 5 g doses (Ostojic and Ahmetovic, 2008).
• Upper amounts studied: up to 30 g a day for 5 years has been described as safe and well tolerated in healthy people (Kreider et al., 2017).

How Much Creatine Per Day: The Standard Dose

Creatine works by raising the creatine stored in your muscles. The most common creatine dosage is 3 to 5 g of creatine monohydrate a day, which fills your muscle stores over about 3 to 4 weeks without a loading phase (Kreider et al., 2017). In a classic study in men, 3 g a day for 28 days produced about the same 20 percent rise in muscle creatine as a week of loading, just more gradually (Hultman et al., 1996).

The key word is daily. The benefit comes from keeping your stores topped up, so take it on training days and rest days alike. Timing matters far less than consistency; see when to take creatine.

What those grams do in the body, from strength to memory, is covered in creatine benefits. For the amounts used in studies on recovery after training, see our guide to creatine for recovery.

Loading vs No Loading

A loading phase uses a higher dose for a few days to fill your stores quickly. The quickest method is about 0.3 g of creatine monohydrate per kg of body weight a day for 5 to 7 days, followed by 3 to 5 g a day to keep the stores full (Kreider et al., 2017). Most protocols split this into four doses of about 5 g.

• With loading: in 31 men, 20 g a day for 6 days raised muscle creatine by about 20 percent, and 2 g a day kept it there for another 30 days (Hultman et al., 1996).
• After loading: after 5 days of 20 g a day, 2 g or 5 g a day kept muscle creatine at post-loading levels for 6 weeks (Preen et al., 2003).

Loading gets you there sooner, not further. It may suit you if you want the full effect within a week; skipping it may suit you if you have a sensitive stomach or want one scoop a day. The full protocol is in our creatine loading phase guide.

Creatine Dose by Body Weight

Loading is the part of creatine dosing that scales with body weight. The table applies the 0.3 g per kg loading formula (Kreider et al., 2017) to common weights, rounded to the nearest gram. The daily amount afterward stays at 3 to 5 g; the maintenance studies cited here used flat amounts of 2 to 5 g a day, not a per kg figure.

Body weight	Loading (0.3 g per kg a day, 5 to 7 days)	Daily amount after loading
120 lb (54 kg)	About 16 g	3 to 5 g
150 lb (68 kg)	About 20 g	3 to 5 g
176 lb (80 kg)	About 24 g	3 to 5 g
200 lb (91 kg)	About 27 g	3 to 5 g
230 lb (104 kg)	About 31 g	3 to 5 g

For your own number, divide your weight in pounds by 2.2, then multiply by 0.3. Many protocols simply round to about 20 g a day. Either way, split it into doses of about 5 g.

Dosage for Women, Older Adults and Vegetarians

Women. The usual 3 to 5 g a day applies. A review of creatine across women's life stages reports benefits for muscle size and function in post-menopausal women taking high doses, around 0.3 g per kg of body weight a day (Smith-Ryan et al., 2021). More is in creatine for women.

Older adults. A meta-analysis of 22 trials in adults with an average age of 57 to 70 found that creatine increased lean tissue by about 1.4 kg and improved upper and lower body strength more than training alone (Chilibeck et al., 2017).

Vegetarians. Creatine in food comes mainly from meat and seafood, and vegetarians have been found to have lower creatine stores (Kreider et al., 2017). In an 8-week training trial, vegetarians taking creatine gained more muscle creatine, lean tissue and total work than meat eaters taking it (Burke et al., 2003). See is creatine vegan?

Doses Used in Brain Research

Brain studies have used a wider range of doses than the standard muscle dose:

• Brain stores: 20 g of creatine a day for 4 weeks raised total creatine in the brain by an average of 8.7 percent (Dechent et al., 1999).
• Memory: a 2023 meta-analysis of randomized trials in healthy people found that creatine improved measures of memory compared with placebo, most clearly in adults aged 66 to 76. The trials used about 2.2 to 20 g a day for 5 days to 24 weeks (Prokopidis et al., 2023).
• Vegetarians: in 45 young adult vegetarians, 5 g a day for 6 weeks improved working memory and reasoning test scores compared with placebo (Rae et al., 2003).
• Sleep loss: a lab study during a night of sleep deprivation used a single dose of 0.35 g per kg of body weight (Gordji-Nejad et al., 2024), a research dose, not a daily one.

Is More Creatine Better?

Not past a point. Your muscles hold a limited amount of creatine, and loading reached about the same level as a low daily dose, only faster (Hultman et al., 1996). Once your stores are full, 3 to 5 g a day keeps them there.

• Upper amounts studied: the International Society of Sports Nutrition position stand describes short and long term supplementation of up to 30 g a day for 5 years as safe and well tolerated in healthy people (Kreider et al., 2017).
• Large single doses: in 59 soccer players taking creatine for 28 days, a single 10 g dose caused diarrhea in 55.6 percent of players, compared with 28.6 percent for two 5 g doses (Ostojic and Ahmetovic, 2008).
• Kidney labs: creatine can raise creatinine without any change in how well your kidneys work (Antonio et al., 2021), and a 2019 meta-analysis concluded that creatine supplementation did not cause kidney damage (de Souza e Silva et al., 2019). Tell your clinician you take it before routine bloodwork.

Early scale weight is usually water; see creatine water retention and creatine side effects.

Counting Grams in Gummies and Capsules

The dose is the same in any format: 3 to 5 g of creatine a day. A gummy or capsule holds far less than a scoop of powder, so check the label for grams of creatine per serving and how many pieces make a serving.

• Do the math: divide your daily target by the grams of creatine in each piece. If a label lists 1 g per gummy, a 5 g day means 5 gummies.
• Count creatine, not total weight: a gummy also contains other ingredients, often sugar, so count only the grams of creatine listed.
• Research on gummies: a 10-week randomized trial in 32 female beach volleyball athletes gave 5 g a day of creatine monohydrate as gummies (Pereira et al., 2026).

Formats are compared in creatine powder vs pills vs gummies. Coffee drinkers can see creatine and caffeine. Products sold as creatine HMB combine creatine with HMB; our guide to creatine HMB vs monohydrate explains how they differ. If you are also looking at taurine, our guide to taurine vs creatine covers the amounts studied for each and taking both.

One scoop matches the top of the standard 3 to 5 g range. More guides on healthy aging and brain health are in our Learn hub.

Safety note: people with kidney disease, those who are pregnant or breastfeeding, and anyone taking prescription medicines should talk with a clinician before taking creatine.

Frequently Asked Questions

Is 5 g of creatine enough?

For most adults, yes. 5 g a day is the top of the standard 3 to 5 g range and fills muscle stores in about 3 to 4 weeks without loading.

Is 3 g of creatine a day enough?

Yes. In one study, 3 g a day for 28 days raised muscle creatine by about 20 percent, similar to a week of loading.

Can you take 10 g of creatine a day?

10 g a day is well under the 30 g a day described as safe in healthy people, but it will not fill your muscles beyond full. If you take it, split it into two 5 g doses.

Do you need to cycle creatine?

Cycling is not part of the standard protocol, and daily use for up to 5 years has been described as safe in healthy people. If you stop, muscle stores drift back down, in one study to their starting level about 30 days later.

Do you need to load creatine?

No. Loading fills your stores in about a week; 3 to 5 g a day reaches a similar level in about 3 to 4 weeks.

How much creatine should a woman take per day?

The same 3 to 5 g a day. Some research in post-menopausal women used around 0.3 g per kg a day.

How much creatine is used for brain health?

Memory trials used about 2.2 to 20 g a day, and a 6-week trial in vegetarians used 5 g a day.

Should I take creatine on rest days?

Yes. Take the same daily amount so your stores stay full.
