How much creatine should you take per day?
The short answer: 3 to 5 grams of creatine monohydrate every day. That's the dose the International Society of Sports Nutrition recommends, and it's the dose used in almost every study that's ever shown a benefit.
You don't need a scale, a blender, or a workout schedule to get this right. You need a habit. The hardest part of creatine is not the math. It's remembering to take it on day 47, when no one is watching and you're tired.
Everything below is a footnote to that.
Dose by body weight
The 3 to 5 g range covers most adults. If you're heavier, lean toward 5 g. If you're smaller, 3 g is plenty. Here's the breakdown researchers cite most often:
| Body weight | Daily dose |
|---|---|
| Under 70 kg (155 lb) | 3 g |
| 70 to 90 kg (155 to 200 lb) | 4 g |
| Over 90 kg (200 lb) | 5 g |
Some research uses a precise formula of 0.03 g per kg of body weight. For a 75 kg person that works out to 2.25 g a day, which is honestly on the low end. If in doubt, round up. Stick with 3 to 5 g unless you have a reason to be more exact.
What a dose actually does in your body
Your muscles store creatine as phosphocreatine, which your cells use to regenerate ATP during short, hard efforts. The average person walking around has muscle creatine stores at about 60 to 80 percent of capacity. Supplementing gets you to 90 to 100 percent.
That's the whole mechanism. The extra 10 to 20 percent is where the strength, recovery, and cognitive effects come from. You can't overfill the tank. Once you're saturated, any extra creatine leaves in your urine.
This is also why you don't need to time it. Your muscles draw from stores built up over weeks. A single dose at 8am versus 8pm changes nothing.
Do you need a loading phase?
No. Loading is a shortcut, not a requirement.
A loading phase is 5 to 7 days of around 20 g a day, split into 4 doses of 5 g, to saturate muscles faster. After that, you drop to 3 to 5 g a day for maintenance.
If you skip loading and take 3 to 5 g a day from day one, you hit the same saturation level in roughly 3 to 4 weeks. Same destination, slower route.
Reasons to load: you want results sooner, typically noticeable strength gains by week 2 instead of week 5. Reasons not to: some people get stomach cramps or feel puffy on 20 g days. If you aren't in a hurry, skip it. Full breakdown of the loading protocol here.
Does the time of day matter?
Not as much as the supplement industry pretends.
Post-workout shows a small edge in some studies, likely because insulin from carbs helps shuttle creatine into muscle cells. If you're optimizing at the margins, take it with a meal that includes carbs. If you're not, take it whenever you'll actually take it.
The only wrong answer is a time you won't remember.
What if you miss a day?
A single missed day barely moves the needle. Your muscle creatine stores drop by about 1 to 2 percent after 24 hours.
Miss a whole week and you start to lose meaningful amounts. Miss a month and you're most of the way back to baseline.
This is the real reason consistency beats perfection. A person who takes 3 g a day 95 percent of the time has higher muscle creatine than a person who takes 10 g a day half the time. The habit matters more than the quantity.
Creatine Today was built around this one idea. Pick a time, get a reminder, log the dose, watch your streak grow. That's the whole app.
Can you take too much?
For a healthy adult, no. Not in any practical sense.
Studies have run 5 g a day protocols for up to 5 years with no kidney or liver issues in healthy participants. Doses of 10 to 20 g a day for weeks at a time have also been tested without harm, though anything above 5 g a day mostly ends up in your urine.
Two real caveats. If you have existing kidney disease, talk to your doctor first. And don't confuse creatine with creatinine, its breakdown product. Taking creatine raises your blood creatinine readings, which can look alarming on a lab test but is not actually a sign of kidney damage. Tell your doctor you supplement.
What form of creatine should you take?
Creatine monohydrate. That's it.
Every newer form, including HCl, ethyl ester, buffered, and nitrate, has been tested against monohydrate. None of them beat it. Most are worse. Micronized monohydrate is fine, just smaller particles that dissolve more easily, but you're paying extra for a solubility tweak.
Monohydrate is cheap, works in hundreds of studies, and has a 30-year safety record. Get the unflavored powder, mix it into water or a smoothie, and move on.
The one thing that actually matters
You can spend hours reading about timing, forms, loading, cycling, stacks with beta-alanine, and whether to take it with grape juice. None of it matters if you're taking creatine three days a week.
The people who get results are the ones who take it every day for months. That's the entire secret.
