Most guidance read for this piece puts creatine at 3 to 5 g a day, every day, with a loading phase optional rather than required. In Great Britain the figure a label’s health claim works to is narrower: both authorised creatine claims in the national register may be made only for a food providing 3 g a day.
That is the short answer to how much creatine per day. This is an evergreen explainer, and the longer answer depends on whose figure you read. This desk read the Great Britain nutrition and health claims register page and its 19 May 2026 spreadsheet, together with the Harvard Health, University of Rochester Medical Center (URMC) and Australian Sports Commission pages, on 15 October 2026.
How much creatine per day do the main guides give?
| Source | Daily figure | Loading |
|---|---|---|
| Harvard Health | 3 to 5 g | Offers no advantage, in its words, and adds kidney stress |
| URMC (dietitian Holly Gilligan) | 5 g for most; 10 g for those close to or above 200 lb | Not necessary |
| Australian Sports Commission | 3 to 5 g maintenance, or 0.03 g per kg | Optional: about 5 g four times a day, or 0.3 g per kg, for about five days |
| GB register: burst-exercise claim | 3 g a day, stated on the pack | Not addressed |
| GB register: over-55 strength claim | 3 g a day, with resistance training at least three times a week | Not addressed |
| GB register: cognitive function (004UKNHCC) | None; the claim is non-authorised | Not addressed |
Is 3 to 5 g of creatine a day the standard dose?
It is the common ground. Harvard Health calls 3 to 5 g “the general recommendation” and says an adult dose in that range is safe, while advising anyone with kidney disease to see a doctor first. URMC’s key takeaways say most people take 3 to 5 g, although its dosing section settles on 5 g for most and 10 g for heavier people, a figure the page does not source in the text read. The Australian Sports Commission gives 3 to 5 g as the maintenance amount.
None of the three is a UK body; they are dosing references.
How much creatine for a loading phase?
The Australian Sports Commission sets out two routes. Loading means about 5 g four times a day for about five days, or roughly 0.3 g per kilogram of body mass a day split across meals, then a maintenance dose of 0.03 g per kilogram once a day. Skipping the load and taking 3 to 5 g a day reaches saturation over about four weeks instead.
On this desk’s arithmetic from those figures, a 70 kg adult would take about 21 g a day while loading and about 2.1 g a day afterwards. The commission adds that uptake is larger when creatine follows a meal with protein and carbohydrate, and that people with the lowest stores, such as vegetarians, have the most room to rise.
The American sources disagree on loading. Harvard Health says it puts more stress on the kidneys for no gain; URMC calls loading unnecessary and says there is no evidence that creatine causes kidney injury. This desk reports both views and takes neither.
What may a GB label say about creatine dose?
The register page says it “sets out all authorised and rejected nutrition and health claims”, and that only authorised claims may be used in Great Britain. The burst-exercise claim, under Regulation (EU) 432/2012, may be used only for a food providing a daily intake of 3 g, the consumer must be told the effect comes at that intake, and the claim may target only adults doing high-intensity exercise. The over-55 claim, under Regulation (EU) 2017/672, ties the same 3 g to regular resistance training.
The 3 g is a condition of making a claim. It is not a recommended dose, nor a legal limit. What the register adds is that a cognitive-function claim, 004UKNHCC, was entered as non-authorised on 27 February 2025. The effects post sets out the full list, and how format changes the label is reviewed separately. None of the three dosing pages read here mentions the GB register.
Frequently asked questions
Is 5g of creatine a day enough?
On the guidance read here, yes for most adults. Harvard Health and the Australian Sports Commission both give 3 to 5 g a day as the standing amount, and URMC calls 5 g appropriate for most people. Five grams is also above the 3 g daily intake Great Britain’s register attaches to both authorised creatine claims.
Do I need a creatine loading phase?
No source read here says it is required. The Australian Sports Commission describes loading, about five days of it, as the quicker route; 3 to 5 g a day alone reaches saturation over about four weeks. URMC says loading is not necessary, and Harvard Health goes further, saying it offers no advantage and adds stress on the kidneys.
Is 10g of creatine too much?
URMC’s page says people close to or above 200 pounds may benefit from 10 g a day, though the text read gives no source for that figure. Harvard Health’s safety statement covers 3 to 5 g. The GB register’s claims are tied to 3 g and say nothing about an upper amount. Harvard Health advises anyone with kidney disease to see a doctor first.
Should I take creatine every day?
The dosing sources read here assume a daily habit: the Australian Sports Commission’s maintenance dose is taken once a day, and URMC says timing matters less than consistency. Both authorised GB claims are also framed around a daily intake of 3 g, and the burst-exercise claim requires the pack to say so.
