How much creatine should you take?
Creatine is one of the most studied supplements in sports nutrition, and the dosing is refreshingly simple. There are two numbers that matter: an optional loading dose that fills your muscle stores quickly, and a maintenance dose that keeps them full.
- Loading (optional): about 0.3 g per kg of bodyweight per day, split into four smaller doses across the day, for 5–7 days. For an 80 kg lifter that's roughly 24 g/day as 4 × 6 g.
- Maintenance: a flat 3–5 g per day, every day, indefinitely. Most people just take 5 g and never think about it again.
The calculator above does this math for you and shows how long until your muscles are fully saturated. Unlike protein, the maintenance dose doesn't really scale with bodyweight — 3–5 g/day saturates almost everyone, so we keep it simple rather than inventing false precision.
Should you do a loading phase?
Loading isn't required — it only changes how fast you saturate, not the final result. Here's the trade-off:
| Protocol | Time to full saturation | Best for |
|---|---|---|
| Loading (0.3 g/kg split 4×, 5–7 days) | ~7 days | You want results fast (before a meet, a cut, a program start) |
| No loading (3–5 g/day from day one) | ~28 days | You'd rather keep it simple and don't mind waiting a month |
Some people get mild stomach discomfort from the higher loading doses. If that's you, split the doses further or just skip loading entirely — a month from now you'll be in exactly the same place.
How long until creatine works?
Creatine doesn't work dose-by-dose like caffeine. It works by saturating your muscle creatine stores, which sit at roughly 60–80% of capacity when you're not supplementing. Once those stores are topped up, you feel the benefit — more reps at a given weight, better performance in short, intense efforts, and slightly faster recovery between sets.
With loading, you're saturated in about a week. Without it, plan on around four weeks at 3–5 g/day. After that, the daily maintenance dose simply keeps the tank full.
When should you take creatine?
Timing is the most over-thought part of creatine. Because the whole point is keeping your stores saturated over time, the day you take it matters far more than the hour. A missed day here and there won't undo your progress, but consistency is what keeps you saturated.
If you want to optimise at the margins, a few studies suggest a small benefit to taking creatine after training rather than before. It's a minor effect — don't lose sleep over it. Take it whenever you'll actually remember to.
How much water should you drink on creatine?
Creatine pulls a little extra water into your muscle cells, which is why you may see 1–2 kg on the scale early on. That's a good thing — it's intracellular water in muscle, not bloat. There's no magic number of extra litres you must drink; just stay normally well-hydrated, especially if you train hard or in the heat.
Which creatine should you buy?
This part is easy, and it saves you money: buy plain creatine monohydrate. It's the form used in the overwhelming majority of the research, it's the most effective, and it's the cheapest. Creapure® is a high-purity, third-party-tested monohydrate if you want a source you can trust.
Ignore the marketing around "advanced," "buffered," "HCl," or liquid creatines — they cost more and don't outperform monohydrate. Unflavored powder mixed into water or a shake is all you need.
Creatine vs. creatinine — not the same thing
These two words get mixed up constantly, so to be clear: creatine is the training supplement this page is about. Creatinine is a waste product your body makes, and doctors measure it (via "creatinine clearance," the Cockcroft-Gault equation) to estimate kidney function. They are different things.
Why it matters: taking creatine can slightly raise your measured creatinine on a blood test, because more creatine in your system means a bit more creatinine as a byproduct. In healthy people this reflects the extra creatine, not kidney damage. If you have a kidney condition, or a lab result you're unsure about, talk to your doctor — and mention that you supplement creatine.
Frequently asked questions
How much creatine should I take per day?
For maintenance, 3–5 grams of creatine monohydrate per day is enough for almost everyone. If you want to saturate faster, load with about 0.3 g per kg of bodyweight per day, split into four doses, for 5–7 days, then drop to 3–5 g/day.
Do I need a loading phase?
No — loading is optional. It fills your muscle stores in about a week; skipping it and taking 3–5 g/day gets you to the same place in roughly four weeks. The end result is identical.
When is the best time to take creatine?
Timing barely matters — taking it consistently every day is what counts. Some studies hint at a small edge to taking it after training, but any time of day works.
Does creatine cause weight gain?
You may gain 1–2 kg in the first weeks, but it's water drawn into your muscle cells, not fat. Many people see it as a plus — muscles look fuller.
Do I need to cycle off creatine?
No. There's no need to cycle. Taking 3–5 g every day continuously is safe in healthy people and keeps your stores topped up.
Can women take creatine?
Yes. Creatine is safe and effective for women at the same doses as men — 3–5 g/day, with an optional loading phase.
Which form of creatine is best?
Creatine monohydrate — the most researched, most effective, and cheapest form. Creapure is a high-purity monohydrate. Fancier forms cost more without working better.
Is creatine safe for your kidneys?
In healthy people, long-term 3–5 g/day is well tolerated. Creatine can slightly raise measured creatinine (a lab marker) without harming the kidneys. If you have kidney disease, check with your doctor first.
