How Much Creatine Should You Take Per Day?
Last updated: August 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
3–5 g daily. That saturates muscle stores in about four weeks and maintains them indefinitely. Larger people and those with more muscle mass sit at the upper end; there is no benefit to going beyond 5 g once saturated.
Key takeaways
- 3–5 g daily is the maintenance dose for essentially everyone.
- Loading at 20 g/day for 5–7 days is faster but causes more digestive upset.
- More than 5 g once saturated does nothing except cost money.
Why 3–5 g
Muscle creatine stores are around 60–80% saturated on a normal diet. Daily supplementation at 3–5 g closes that gap over roughly four weeks and then keeps it closed, because you excrete a fairly constant amount each day. Once stores are full, additional creatine is simply excreted.
Body size and diet
Larger individuals and those with more muscle have more storage capacity, which is the argument for 5 g rather than 3 g. Some protocols scale to 0.03 g per kg body weight. Vegetarians and vegans start lower because dietary creatine comes from meat and fish, so they typically see larger changes.
The loading question
20 g daily split into four doses for 5–7 days reaches saturation in under a week rather than four. It is not required, and it causes noticeably more bloating and stomach upset. Unless you have a specific reason to saturate quickly, starting at 3–5 g and being patient is the easier route.
Key ingredients to understand
The ingredients most relevant to this question, with what the evidence actually supports:
- Creatine Monohydrate — Creatine monohydrate is the most researched sports supplement in existence, with hundreds of trials supporting increased strength and lean mass…
- Creatine — Creatine is one of the most studied and effective sports supplements, with solid evidence for strength and high-intensity performance. Newer…
- Whey Protein — Whey is a complete, rapidly absorbed protein high in leucine, and it has as strong an evidence base for muscle protein synthesis as anything in…
- HMB (Beta-Hydroxy Beta-Methylbutyrate) — HMB is a leucine metabolite sold for muscle preservation. The evidence is genuinely split: it does little for trained athletes already eating…
Frequently asked questions
Do I take it on rest days?
Yes. Saturation is maintained by daily intake, and rest days are no different.
Does timing matter?
Very little. Consistency matters far more than the hour.
Can I take more than 5 g?
You can, and it will be excreted. Higher doses are used in some neurological research, not for muscle.
