How Much Creatine Per Day? Loading, Maintenance, and the 3g vs 5g Question
Take 3 to 5g of creatine monohydrate a day, every day, rest days included. That is enough for most adults to fill their muscle stores and keep them full, and timing around workouts does not matter. A loading phase of about 20g a day for a week is optional and only gets you there two to three weeks faster.

Take 3 to 5g of creatine monohydrate every single day, rest days included, because it works by keeping your muscles saturated over time rather than by timing around workouts. A loading phase of around 20g a day for a week is optional: it reaches full saturation two to three weeks faster but is not necessary and can upset some stomachs. Consistency is the whole game, so build a daily habit you will actually stick to. Any pure monohydrate does the job.
Creatine works on a saturation model. Muscle creatine stores rise to a ceiling (roughly 150 millimoles per kilogram of dry muscle) and stay there as long as you keep taking it. Below that ceiling, creatine continues to build. At the ceiling, additional creatine produces no extra benefit. The daily dose you need is whatever reaches and maintains that saturation point: 3 to 5 grams per day for most adults. If you want to take it in your protein shake, see mixing creatine with protein powder.
What is the daily creatine dose?
The maintenance dose is 3 to 5 grams of creatine monohydrate per day, taken every day, indefinitely. This is the dose that keeps muscle creatine stores saturated once they are full. There is no benefit to taking more. There is a steady decay of stored creatine if you stop taking it, dropping back to baseline over about 4 to 6 weeks.
Body weight matters but not as much as marketing sometimes suggests. A 70kg lifter and a 100kg lifter both saturate at the same 3 to 5 gram daily range. Larger users may benefit from the upper end of the range (5 grams) while smaller users hit saturation comfortably at 3 grams. The delta is small enough that most people default to a 5 gram scoop and stop thinking about it.
Do you need a loading phase?
A loading phase is optional. The protocol is 20 to 25 grams per day for 5 to 7 days, split into 4 to 5 doses through the day (so roughly 5 grams four times per day with meals). This fills muscle creatine stores in about a week instead of the 3 to 4 weeks that the maintenance-only route takes.
There is no long-term performance advantage to loading. After 4 weeks both routes reach the same saturation and produce the same strength and muscle gains. The only reason to load is if you want the ergogenic effect sooner, for example in the run-up to a competition or the first month of a structured training block.
Loading has two drawbacks. Some users experience GI discomfort on the 20 to 25 gram daily doses; spreading across 4 smaller doses mitigates this but does not eliminate it. Loading also temporarily increases body water weight by 1 to 2 kilograms as muscle cells draw in water alongside creatine. This water weight is normal and expected, not a fat gain, but it can feel unwelcome for users cutting weight.
Is 3g of creatine enough, or do you need 5g?
Three grams per day is enough to reach and maintain muscle creatine saturation for most adults. The 5 gram recommendation is historical and reflects the upper end of the safe effective range. Both produce comparable results at steady state.
This matters for UK buyers because MyProtein doses Impact Creatine and THE Creatine at 3 grams per scoop, while Optimum Nutrition and Bulk default to 5 grams. If you are running MyProtein, 3 grams per day is fine for maintenance. One scoop, taken every day, reaches saturation in about 4 weeks. You do not need to double-scoop unless you want to accelerate the onset, in which case 6 grams per day for the first week approximates a mini-load.
Larger users (over 95kg) training heavy compound lifts 4 to 6 times per week may see a slight incremental benefit from 5 grams over 3 grams. Everyone else has no data-supported reason to go above 3 grams once saturated.
When should you take creatine?
Creatine timing does not matter for the saturation model. Take it whenever you will remember to take it every day. Most users default to adding it to a protein shake post-workout; this works because the insulin response to carbs and protein may slightly increase creatine uptake into muscle, and because the habit is already in place.
On rest days, take it at any time. On training days, take it within a 2 hour window of your workout if you want to optimise uptake. Adherence matters far more than timing: a daily dose taken at any time for 30 days saturates muscle better than a perfectly-timed dose taken 20 times in the same period.
How long until you see results?
Without loading: 3 to 4 weeks to full saturation. You will start noticing small strength increases in week 2 to 3, typically a 2 to 5 percent improvement on heavy compound lifts at saturation. With loading: 5 to 7 days to full saturation, then the same strength benefits.
Water retention appears faster than strength. Most users see 1 to 2 kilograms of scale weight increase in the first 2 weeks as muscle cells draw in water alongside creatine. This is the intended effect: intracellular hydration supports protein synthesis and muscle fullness. It is not fat.

Why Does My Protein Bar Taste Artificial? Ingredients to Avoid
Protein bars taste artificial mostly because of what replaces the sugar: polyols such as maltitol, usually paired with an intense sweetener such as sucralose. Polyols are also the usual reason bars cause wind and bloating. The Myprotein Layered Bar in Hotel Chocolat Salted Caramel has no maltitol and no intense sweetener.

What Is in Pre-Workout, and What Does It Cost?
Pre-workout is mostly caffeine plus citrulline, beta-alanine and sometimes creatine, and caffeine does most of the work. A serving costs 53p to 93p on the brands' own sites.
