How to Take Creatine: Dosage, Loading, Timing and Rest Days Explained

Creatine monohydrate is the most researched performance supplement on the planet, and it sits in Group A of the Australian Institute of Sport's framework, which is the tier reserved for products with strong evidence behind them. That makes it one of the few Supplements genuinely worth the shelf space in an Australian athlete's kitchen. The catch is that almost every question people actually have about it, such as how much creatine per day, whether to load, and whether to bother on rest days, gets answered differently depending on who you ask. This guide settles it using AIS guidance and the International Society of Sports Nutrition position stand, then turns it into a protocol you can follow without thinking about it.

What creatine actually does

A quick bit of context, because it explains every dosing decision that follows.

According to the AIS, creatine is a non-essential nutrient that your body synthesises at a rate of around 1 g per day, with roughly another 1 g per day coming from the diet. It is heavily concentrated in animal muscle such as meat and fish, which is why muscle and blood creatine levels are reduced in vegetarians who eat little of it.

Most of it is stored in skeletal muscle in free and phosphorylated forms, where it fuels brief, intense effort. The AIS notes that although the rate of energy production from muscle creatine is very high, storage capacity is very limited, with only enough in skeletal muscle to support about 8 to 10 seconds of maximal exercise.

Supplementing does one thing: it tops those stores up beyond what food and your own production can manage. A fuller tank means more repeat sprints, more reps at a given weight, and over time more lean mass.

How much creatine should I take every day?

3 g to 5 g of creatine monohydrate per day. That is the maintenance dose, and for the large majority of people it is the entire protocol.

The AIS cites the work of Professor Eric Hultman, who showed that elevated muscle creatine can be maintained after loading with a maintenance dose of about 3 to 5 g per day.

There is also a body-weight formula if you prefer precision. The AIS gives maintenance dosing as 0.03 g per kilogram of body mass once daily.

Notice the formula produces lower numbers than the familiar 5 g scoop. Both are correct. The 3 g to 5 g range is the practical version, rounded up to give a margin of safety and to account for larger athletes. The ISSN position stand notes that larger athletes engaged in intense training may need 5 g to 10 g per day to maintain optimal whole body creatine stores.

Is 5 g of creatine enough?

Yes. For most people 5 g daily is comfortably enough, and it is the figure almost every study uses for the maintenance phase.

The only groups with a case for going higher are athletes well above 90 kg carrying a lot of lean mass, and those training at very high volume. Even then the ceiling of usefulness is low. Going from 5 g to 10 g will not double anything. Once your muscle is saturated, extra creatine is simply excreted.

Where 5 g is not enough is during a loading phase, which is a different question entirely.

Do I need a loading phase?

No. You have two valid routes to the same destination, and the only real difference is speed.

Route 1: Load, then maintain

The AIS describes the classic protocol confirmed by multiple research teams: muscle creatine can be increased by ingesting about 5 g of creatine monohydrate, four times per day, for about five days. That is 20 g daily, split into four doses.

The body-weight version is 0.3 g per kilogram of body mass per day for 5 days, typically in 3 to 4 divided doses taken with meals, followed by the 0.03 g/kg maintenance dose from then on.

Route 2: Skip loading entirely

The AIS is explicit that you can bypass the loading phase, simply ingest a maintenance dose of 3 to 5 g per day, and increase muscle creatine to saturation levels over about four weeks.

Same end point. Slower arrival.

Which should you choose?

Load if you have a specific date to be ready for, such as a pre-season, a competition block, or a testing week. Otherwise skip it. Most people training year round have no reason to rush four weeks into five days, and the AIS specifically lists avoiding the loading phase in favour of the lower-dose, longer-duration protocol as one of the sensible decisions for avoiding gastrointestinal upset.

Should creatine be taken before or after training?

After, with your post-workout meal. This is the one timing recommendation with a mechanism behind it rather than gym folklore.

Muscle creatine uptake is insulin mediated, so pairing creatine with something that raises blood insulin improves how much ends up in the muscle. Exercise itself has insulin-like effects, which stacks the two together.

The AIS is careful not to overstate it. There are not many data demonstrating that post-exercise creatine ingestion beats pre-exercise ingestion, but the AIS describes taking creatine following exercise and with the post-exercise meal as prudent advice, partly because it helps athletes build the habit of eating properly after training.

That last point matters more than the timing itself. Creatine taken with your post-training meal is creatine you will not forget.

Should I take creatine on rest days?

Yes, every day. This trips up more people than any other part of the protocol.

Creatine does not work acutely like caffeine. It works by keeping your muscle stores saturated, and saturation is a function of consistent daily intake, not of whether you trained. Skipping rest days means your stores drift down, which is exactly what you spent weeks building up.

On a rest day, take it with any meal. Timing is irrelevant when there is no session to anchor it to.

Do you need to cycle creatine?

No. The cycling advice is a holdover from an era when people worried that supplementing would permanently suppress the body's own creatine production. The research never supported it, and reviews now note that continued evidence suggests cycling is not necessary, particularly given the benefits of ongoing supplementation.

There is no tolerance effect. Your muscle either holds a full load of creatine or it does not. Taking a month off simply means draining the tank and refilling it.

How long should you take creatine?

As long as you want the benefits, which in practice means indefinitely.

The ISSN position stand puts it plainly: there is no compelling scientific evidence that short-term or long-term use of creatine monohydrate, at up to 30 g per day for 5 years, has any detrimental effects on otherwise healthy individuals. The AIS adds that there is no evidence of systematic serious adverse effects, and that speculation about muscle, renal and thermoregulatory dysfunction is not supported by research or post-marketing surveillance.

One trial followed professional basketball players taking 5 g per day across three competitive seasons and found no clinically significant changes in health markers.

If you have existing kidney disease or any other medical condition, that is a conversation for your doctor, not for a blog post.

What happens if you miss a day?

Essentially nothing. Creatine has a long residence time in muscle, so one missed day barely moves your saturation level. Take your normal dose the next day and carry on. There is no need to double up.

Where it matters is pattern rather than incident. The AIS notes that after you stop supplementing altogether, muscle creatine and body mass return to normal slowly over four to six weeks. So a forgotten Tuesday is noise. Six weeks of forgetting is a reset.

Should creatine be taken with food?

Yes, for two separate reasons.

Absorption. Because uptake is insulin mediated, taking creatine with a meal helps. Early studies used very large amounts of simple sugar to drive that insulin response, but the AIS notes that subsequent research confirmed the same effect from ingesting creatine after a meal containing both protein-rich and carbohydrate-rich foods, in the order of 50 g of each.

That is a useful spec, because it describes a normal meal rather than a sugar bomb. Several meals in our Muscle Meals range land in that territory on their own, with the Smokey BBQ Pulled Beef with High Protein Cheesy Mac carrying 56 g of protein and 67 g of carbohydrates in one container.

Comfort. Some people report mild, temporary stomach upset on creatine. The AIS lists taking it with meals as one of the practical fixes, alongside skipping the loading phase and not taking it at the same time as high-fibre foods or supplements known to cause gastrointestinal disturbance, such as sodium bicarbonate.

Can creatine be mixed with a protein shake?

Yes, and it is one of the better ways to take it. A whey shake with carbohydrates ticks the insulin box, and if you are already having one after training you have solved the habit problem too.

One important detail that most articles miss: mix it and drink it straight away. The AIS warns that creatine supplements should be ingested immediately after mixing, because in liquid form creatine degrades to creatinine, which does nothing for you. Pre-mixing a shaker in the morning for an evening session is wasting product.

Hot drinks are also a poor vehicle. Stick to water, milk or a protein shake at normal temperature.

How long before creatine starts working?

It depends which route you took.

• With loading: stores are substantially elevated within about five days, so expect to notice something in the first week or two.
• Without loading: saturation takes about four weeks, so give it a month before judging.

What "working" feels like is usually subtle and specific. More reps at the same weight. A fourth hard sprint that feels like the second one. Slightly better session-to-session recovery. It is not a stimulant, so there is nothing to feel on the day.

Two other things worth expecting. First, weight gain. The AIS explains that increased muscle creatine is associated with increased body water, typically a maximum of 1 kg to 2 kg, and that this persists as long as stores stay elevated. For most people chasing size that is fine, but it is a genuine consideration if you compete in a weight-class sport and need to make weight.

Second, individual variation. The AIS notes that people with the lowest starting muscle creatine, such as vegetarians, have the largest potential for increase. If you eat a lot of red meat already, your response will be more modest.

Which form of creatine should you buy?

Creatine monohydrate. There is no debate here worth having.

The AIS states that creatine monohydrate is very well absorbed at over 99%, that alternative forms such as creatine ethyl ester advertising better absorption have no data behind those claims, and that about 99% of all safety and efficacy data concerns monohydrate powder. Its conclusion is blunt: there is no scientific reason to take a creatine supplement other than creatine monohydrate.

Anything sold as HCl, ethyl ester, buffered or "advanced" is a more expensive way to buy a worse-evidenced product.

If you are a tested athlete, batch testing is not optional. Sport Integrity Australia maintains guidance and a batch-tested product list, and the AIS points athletes there directly. Our supplements range is built around HASTA certified products for this reason, including BSC Pure Creatine.

The protocol, in one place

For someone who just wants the answer:

1. Buy creatine monohydrate powder. Batch tested if you compete.
2. Take 5 g per day, every day, training or not.
3. Skip loading unless you have a deadline. If you do load, take 0.3 g/kg per day split over 4 doses for 5 days, then drop to 5 g.
4. Take it with your post-training meal on training days, with any meal otherwise.
5. Mix it and drink it immediately.
6. Do not cycle. Do not stop. Give it four weeks before you judge it.
7. Expect 1 kg to 2 kg of water weight early on.

Fuel the training, not just the supplement shelf

Creatine is a multiplier, not a foundation. It makes a good training block better, and it does nothing at all for a week of skipped meals and 60 g of protein a day. The athletes who get the most out of it are the ones whose protein and calories are already handled.

That is the part we take off your plate. Fresh, chef-prepared, macro-labelled meals delivered across NSW, VIC, QLD and ACT, fuelling UFC champions and NRL squads including the Manly Sea Eagles and Wests Tigers.
