How much creatine per day? The evidence-based answer

Every claim is backed by peer-reviewed research (linked below). No sponsors — if we recommend something, it is because it works.

How much creatine to take daily: 3–5 g of monohydrate, every day, timing irrelevant. Loading is optional. What the research actually shows.
Quick answer: take 3–5 g of creatine monohydrate per day, every day, including rest days. Timing does not matter — what fills the muscle is consistency, not the hour you take it. A loading phase is optional: it saturates faster but you reach the same point in 3–4 weeks either way. Nothing fancier than plain monohydrate is needed.

📌 Key numbers

Daily dose
3–5 g of monohydrate
Form with the evidence
monohydrate (not “alkaline” or HCl)
Timing
irrelevant — consistency is what matters
Loading phase
optional: 20 g/day for 5–7 days
Rest days
take it too — dosing is daily

The daily dose: 3–5 grams

The maintenance dose that keeps your muscle creatine stores saturated is 3 to 5 grams per day. This is one of the most consistent findings in sports nutrition: above roughly 3 g/day the stores stay full, and going higher does not build more muscle. Bodyweight matters a little — a 100 kg athlete sits at the top of that range, a 60 kg one at the bottom — but 5 g/day is a safe, simple default for almost everyone.

Creatine does not work like a pre-workout. It builds up in the muscle over days and stays there. That is why the creatine loading phase is optional and why the day-to-day total, not the single dose before training, is what counts.

Do you need a loading phase?

No — it just changes how fast you get there.

Loading vs. no loading: same destination
Approach Protocol Time to full saturation
No loading 3–5 g/day 3–4 weeks
Loading 20 g/day (4×5 g) for 5–7 days, then 3–5 g/day ~1 week

Both routes end at the same muscle creatine content. Loading only makes sense if you want the effect sooner (before a specific date) and you tolerate the larger dose without stomach discomfort. Otherwise, skip it and take 3–5 g daily from day one. Full detail in the creatine loading phase.

When should you take it?

Whenever you will not forget. The idea that creatine must be taken right after training, or with a specific meal, is not supported: because the goal is to keep the muscle saturated over weeks, the exact minute of a single dose is irrelevant. Pick a fixed daily anchor — with breakfast, in your protein at breakfast shake, with dinner — and be consistent.

You can take it with coffee, too. The old claim that caffeine «cancels» creatine comes from a single dated study and has not been replicated.

The weight you gain at first is water — and that is fine

In the first week or two many people gain 1–2 kg. That is water drawn into the muscle cell, not fat. It is part of how creatine works, not a side effect to avoid. It also means creatine only helps when paired with training and enough daily protein target — it lets you do a rep or two more; the muscle is built by the stimulus.

Frequently asked questions

How much creatine should I take per day?
3–5 g of creatine monohydrate daily, every day including rest days. Bodyweight shifts it slightly (5 g for larger athletes), but 3–5 g is the evidence-based range for almost everyone.
Is it better to take creatine before or after a workout?
Neither — timing does not meaningfully change results. Muscle saturation depends on taking it consistently over weeks, so take it whenever you will remember.
Do I need to load creatine?
No. Loading (20 g/day for 5–7 days) saturates faster, but 3–5 g/day reaches the same point in 3–4 weeks. Loading is optional and only worth it if you want the effect sooner.
Should I take creatine on rest days?
Yes. The dose is daily. On rest days the timing matters even less — just keep the streak.
Can I take creatine with coffee?
Yes. The idea that caffeine blocks creatine comes from one old, unreplicated study. Take them together if that is easiest.
