Micronised vs Regular Creatine: Is There a Difference?

Micronised vs regular creatine comes down to particle size, not results: both are the same creatine monohydrate, and micronised creatine has simply been milled finer so it mixes more easily. Your muscles absorb and use both the same way, so choose on price, how well it mixes and whether you need a batch-tested product.

Plenty of labels suggest micronised creatine is a stronger or "better absorbed" form. The research does not back that up. Here is what micronising actually changes, what it does not, and how to pick a creatine in Australia.

Micronised vs regular creatine at a glance

The solubility figure comes from a 2022 review of creatine research. Most creatine powders we sell are micronised, so you rarely have to pay extra for it.

What is micronised creatine?

Micronised creatine is ordinary creatine monohydrate that has been milled into much finer particles. The chemical is identical: the same molecule, the same amount of creatine per gram and the same dose of 3 to 5 g a day. Optimum Nutrition's Micronized Creatine Powder, for example, lists creatine monohydrate as its only ingredient, with "Other ingredients: None" on the label.

Smaller particles have more surface area, so they spread through water faster, stay suspended longer and leave less grit at the bottom of the glass. That is a real, practical benefit if you drink creatine in water every day. It is a mixing benefit, though, not a performance one.

Does micronised creatine absorb better?

No good evidence says it does. A 2022 critical review by Kreider, Jäger and Purpura found that standard creatine monohydrate is already nearly 100% bioavailable when you swallow it, with less than 1% broken down during digestion. The same review states there is no evidence that micronised versions are more bioavailable than creatine with normal-sized particles.

It also makes sense when you think about how creatine works. Its benefits come from filling your muscle stores over days and weeks. Once your muscles are full, small differences in how fast a dose dissolves do not change how much creatine your muscles hold.

The Australian Institute of Sport puts it plainly: there is no scientific reason to take a creatine supplement other than creatine monohydrate. Micronised and regular creatine both meet that bar, which is why they are a better-researched choice than newer forms that claim "better absorption" without the research.

Mixing, grit and stomach comfort

Why creatine never fully dissolves in a small cold glass

Creatine monohydrate is not very soluble, whatever the particle size. According to the 2022 review, about 14 g dissolves per litre of water at 20 °C, but only about 6 g per litre at fridge temperature. So a 5 g scoop needs roughly 360 ml of room-temperature water to dissolve completely, and much more if the water is ice cold. Micronised creatine mixes faster and stays suspended, but it does not change those limits.

The grit at the bottom is still creatine, so swirl and finish it. A room-temperature drink, a protein shake or juice all work. Mix it and drink it straight away, because the AIS notes creatine breaks down when it sits in liquid.

Does micronised creatine cause less bloating or stomach upset?

There is no good research comparing the two forms for stomach comfort. Dose size matters more. In a study of 59 soccer players, a single 10 g dose caused diarrhoea in 55.6% of players compared with 28.6% when the same amount was split into two 5 g doses. Stick to 3 to 5 g at a time, take it with food if your stomach is sensitive, and split loading doses into four servings. If you are wondering about timing, read our guide to the best time to take creatine.

Which creatine should you buy?

Because the form makes little difference to results, compare the cost per 5 g serve, the testing and how you like to take it. Here are some of our best sellers at the time of writing:

• Best value: Beast Labs Creatine Monohydrate is micronised and costs the least per 5 g serve.
• Most popular: Legit Creatine Monohydrate is our best-selling creatine over the last six months, with 5 g of micronised creatine per scoop.
• Trusted brand: ON Micronized Creatine is one of the best-known creatines in the world. Australian labels list a 3 g serve, so check the scoop size and follow the label directions.
• Prefer a named raw material: ATP Science Creapure Creatine uses Creapure creatine monohydrate. It is not labelled micronised, so expect a little more grit.

If you compete in a drug-tested sport, check the Sport Integrity App for batch-tested products before you buy. Compare more options in our best creatine guide or browse the full creatine range. Women can use creatine the same way, as covered in our creatine for women guide.

Our verdict: is micronised creatine worth it?

Micronised creatine is worth choosing if you mix creatine into water and dislike grit, especially when it costs the same as regular creatine, which it often does. It will not make creatine work faster or better. If a regular creatine monohydrate is cheaper or has the testing you need, it will give you the same results. Either way, take 3 to 5 g every day.

FAQs

Is micronised creatine better than regular creatine?

Not for results. Both are creatine monohydrate, and a 2022 review found no evidence that micronised creatine is more bioavailable than regular creatine, which is already nearly 100% absorbed. Micronised creatine mixes more easily and leaves less grit, which is a practical benefit if you drink it in water. Choose on price, mixability and testing.

Is micronised creatine still creatine monohydrate?

Yes. Micronising only mills the powder into smaller particles. The molecule, the creatine content per gram and the dose stay the same, so the research on creatine monohydrate applies to micronised products too. Check the label lists creatine monohydrate as the only active ingredient.

Why does my creatine not dissolve?

Creatine monohydrate is not very soluble. About 14 g dissolves in a litre of room-temperature water and only about 6 g in fridge-cold water, so a 5 g scoop in a small cold glass will leave grit. That grit is still creatine, so swirl and drink it all. Micronised creatine mixes faster, and a room-temperature drink or shake helps.

Does micronised creatine cause less bloating?

There is no good research showing it does. Stomach upset with creatine is linked more to dose size: a study in soccer players found a single 10 g dose caused more diarrhoea than two 5 g doses. Stick to 3 to 5 g at a time, take it with food if you have a sensitive stomach and drink enough water through the day.

How much micronised creatine should I take a day?

The same as regular creatine: 3 to 5 g a day, every day. If you want faster results, you can load with about 20 g a day split into four doses for five days, then drop to 3 to 5 g. Check the scoop size on your tub, as some Australian labels list a 3 g serve rather than 5 g.
