Everything you need to know about creatine - how it works, how to take it, what the research actually says, and how to choose a quality product. Tap a question to expand the answer.
The Basics
What is creatine and how does it work?
Creatine is a compound your body makes naturally and gets from meat and fish. About 95% is stored in your muscles as phosphocreatine, where it helps rapidly regenerate ATP - the energy your muscles burn during short, hard efforts like lifting, sprinting or jumping. Supplementing raises those stores above what diet alone provides.
The science behind creatine and ATP - in plain English?
ATP is the "battery" your muscles drain in the first few seconds of any hard effort. Phosphocreatine recharges that battery. More creatine in your muscle means faster recharge between reps and sets.
How long does creatine take to work?
Full muscle saturation takes about 3–4 weeks at 3–5 g per day, or 5–7 days with a loading phase. Most people notice performance changes within 2–4 weeks of consistent use.
Does creatine expire?
Creatine monohydrate is one of the most stable supplements you can buy. Stored dry and sealed, it stays potent well past printed dates. Moisture is the enemy, not time.
What happens if I stop taking creatine?
Muscle stores return to baseline over 4–6 weeks. You don't lose the muscle you built - you just lose the extra intracellular water and a small performance edge. There's no rebound or withdrawal.
Is creatine natural?
Yes. Your liver and kidneys produce roughly 1 g per day, and you get more from red meat, poultry and fish. Supplementing just tops up what your diet already provides.
Does creatine help brain health?
Emerging research suggests creatine may support cognitive performance, especially under sleep deprivation or in people with lower baseline stores such as vegetarians. The evidence is promising but still developing.
Does creatine improve endurance or just strength?
The biggest gains are in strength, power and short-burst efforts. Endurance athletes still benefit from better recovery between hard intervals - but it isn't a direct endurance booster.
Safety & Common Concerns
Does creatine cause hair loss?
No good evidence supports this. The claim traces back to one 2009 study measuring DHT (not hair). A 2025 randomised controlled trial that directly measured hair follicle health found no effect.
Is creatine bad for your kidneys?
Not in healthy people. A 2025 meta-analysis of 21 studies and multiple gold-standard GFR trials show no adverse effect on kidney function at standard doses. If you have pre-existing kidney disease, speak to your doctor first.
Does creatine cause bloating or water retention?
Creatine draws water into muscle cells (intracellular), not under the skin. That gives muscles a slightly fuller, firmer look - not the puffy, subcutaneous bloating people fear.
Is creatine a steroid?
No. Steroids are synthetic hormones. Creatine is a naturally occurring amino acid derivative found in food. It's a legal, well-studied supplement - not a hormone.
Does creatine cause acne?
There's no clinical evidence linking creatine to acne. If breakouts appear when starting, likelier culprits are new training intensity, sweat and hygiene, or diet changes.
Will creatine make me look puffy?
No. The water it holds is inside muscle cells, which visually reads as fuller and firmer - not soft or puffy.
Is creatine safe for teenagers?
The ISSN position stand states creatine is safe for adolescents when dosed appropriately. Under-18s should have parental guidance and a properly programmed training routine before supplementing.
Does creatine cause cramps or dehydration?
The evidence points the other way - creatine may actually reduce cramping and heat stress. Multiple studies in athletes training in heat found no increase in either.
Is creatine safe long-term?
Studies have followed daily users for 5+ years with no negative effects in healthy adults. It's one of the most-studied supplements in existence.
Can I take creatine while pregnant or breastfeeding?
There isn't enough safety data to give a confident answer. Speak to your GP before supplementing during pregnancy or breastfeeding.
Dosing & Usage
How much creatine should I take per day?
3–5 g daily. Consistency matters far more than timing - every day, indefinitely.
Do I need to do a loading phase?
No. Loading (20 g per day split over 5–7 days) reaches saturation faster, but 3–5 g per day over 3–4 weeks gets you to the same endpoint. Loading isn't necessary and can cause GI discomfort in some people.
When is the best time to take creatine?
Consistency matters more than timing. Pre- or post-workout are both fine; on rest days, take it whenever you'll remember.
Should I take creatine on rest days?
Yes. Daily dosing keeps muscle stores saturated. Missing days won't ruin progress, but daily is the simplest habit.
How do I mix creatine? Does it fully dissolve?
Micronised creatine stirs or shakes cleanly into most fluids. It may not fully dissolve in cold water - that's normal. Any grit at the bottom is still bioavailable; just drink it.
Can I mix creatine with coffee, juice or protein shakes?
Yes to all three. The old "coffee kills creatine" claim doesn't hold up in modern research. Juice and protein shakes are fine too - some evidence suggests carbs and protein modestly improve uptake.
How much water should I drink with creatine?
Drink to thirst. There's no specific extra intake required beyond normal training hydration.
Do I need to cycle creatine?
No. Cycling is a myth carried over from other supplement categories. Continuous daily use is safe and gives the best results.
Can I take creatine on an empty stomach?
Yes. Some people prefer taking it with food or a shake for comfort, but there's no rule against fasted intake.
Does creatine break a fast?
Pure creatine monohydrate has essentially zero calories and won't spike insulin, so most intermittent fasting protocols treat it as fast-safe.
Results & Expectations
How much strength can I realistically gain?
Meta-analyses show creatine typically adds 8–14% more strength gain on top of what training alone produces. Individual response varies.
How much muscle will I build?
Around 1–2 kg of extra lean mass over 4–12 weeks compared to placebo - assuming consistent training and enough protein. Creatine amplifies training; it doesn't replace it.
Why isn't my creatine working?
Common reasons: inconsistent daily use, undertraining, not enough protein or food to support growth, unrealistic expectations, or (less commonly) being a non-responder.
Am I a creatine non-responder?
Around 20–30% of people gain little muscle water or performance from supplementation. Non-responders tend to already have high baseline stores - often high red-meat eaters. It's not a defect.
What actually changes before and after?
Expect a small bump in body weight (1–2 kg water), fuller-looking muscles, more reps at the same load, and quicker recovery between sets.
How do I tell if creatine is working?
Look for more reps at the same weight, faster recovery between sets, and slightly fuller-looking muscles after 3–4 weeks of consistent use.
Does creatine cause weight gain?
Yes - but it's water inside your muscles, not fat. Expect about 1–2 kg in the first few weeks. This is a sign it's working, not a side effect to avoid.
Comparing Types of Creatine
Creatine monohydrate vs HCL - which is better?
Monohydrate is the most researched form, with hundreds of RCTs behind it. HCL is more soluble, but there's no clinical evidence it works better or has fewer side effects at proper doses. Monohydrate remains the gold standard.
Monohydrate vs ethyl ester?
Studies have consistently shown ethyl ester is inferior to monohydrate at raising muscle creatine stores. Skip it.
Micronised vs regular creatine?
Both are chemically identical creatine monohydrate. Micronised has a smaller particle size for easier mixing and less grit - that's the only real difference.
Creatine vs pre-workout - do I need both?
They do different jobs. Creatine builds baseline muscle energy over weeks; pre-workout is an acute stimulant hit for one session. Creatine is fine on its own; pre-workout is optional.
Creatine vs protein powder - which should I prioritise?
Protein has the bigger foundational role - hit your daily protein target first. Creatine is the highest-ROI second supplement once protein intake is dialled in.
Branded vs bulk creatine - is it worth paying more?
What matters is purity, testing and origin - not the label. A cheap product with unverified purity or no testing paperwork isn't a real saving.
Stacking With Other Supplements
Can I take creatine and caffeine together?
Yes. Older claims that caffeine blocks creatine haven't held up; modern research supports taking them together.
Creatine and protein powder together?
Great pairing. Post-workout is a natural time for both. No interaction; they support different mechanisms.
Creatine and beta-alanine - do they stack?
Yes, cleanly. Creatine supports short high-intensity efforts; beta-alanine supports medium-duration efforts (1–4 min). Complementary, not competing.
What other supplements stack well with creatine?
Whey protein, beta-alanine and caffeine are the most evidence-backed additions. Everything else is optional.
Practical Questions
How should I store creatine?
Cool, dry and sealed. Moisture and heat are the two things to avoid. A pantry cupboard is ideal - not next to the stove or in a humid bathroom.
Can I travel with creatine?
Yes. Creatine is legal to fly with domestically and internationally as a food supplement. Pre-portion into a small container or leave it in original packaging for easy checks.
Who Should Take Creatine
Is creatine good for women?
Yes. It doesn't cause bulking, gender-specific side effects or hormonal changes. Women benefit from the same strength, recovery and cognitive support as men.
Will creatine make me bulky?
No. Building visible muscle mass takes years of dedicated training and a calorie surplus. Creatine slightly fills your muscles with water - it doesn't cause bulk on its own.
Is creatine worth it for beginners?
Yes. Creatine works from day one of your training life. Starting early means you get the strength and recovery benefits during the fastest gain phase.
Creatine for older adults?
Increasingly recommended. Creatine may support muscle mass maintenance and strength - both more valuable after 40. Combined with resistance training, it's one of the highest-impact supplements at this life stage.
Creatine for vegans and vegetarians?
Especially valuable. Without red meat and fish, your baseline creatine stores are lower, so the effect from supplementation is often larger.
Creatine for endurance athletes (runners, cyclists, rowers)?
Useful - mostly for recovery, repeated hard efforts and interval training. Less of a direct endurance boost, more of a support tool.
Creatine for combat sports (MMA, boxing, BJJ)?
Well-suited. Combat sports are repeated high-intensity efforts with short recovery - exactly where creatine's mechanism helps most.
Creatine for AFL and rugby players?
A natural fit. Field sports involve repeated sprints, tackles and jumps - all creatine-responsive efforts.
Should teenagers take creatine?
Position stands say yes, provided training is well-programmed and dosing is appropriate. Under-18s should have parental guidance.
Buying Creatine in Australia
What should I look for when buying creatine in Australia?
Micronised creatine monohydrate, 99%+ purity, third-party tested, made in Australia or with clear country-of-origin. Avoid proprietary blends and vague "creatine complexes".
How do I buy creatine online in Australia?
Direct from a reputable Australian brand is the simplest route - you get local shipping, local support, and clear compliance under FSANZ. No prescription required.
Is creatine legal in Australia?
Yes. It's regulated as a general food under FSANZ, not a therapeutic good. No prescription needed.
Is Australian creatine regulated?
Yes - under Food Standards Australia New Zealand (FSANZ). Reputable brands also carry additional certifications like HASTA (banned-substance testing) or HACCP food-safety programmes.
What does "99%+ purity" actually mean?
It's the percentage of the powder that's verified creatine monohydrate, with the remainder being trace moisture and residuals. Anything at or above 99% is high quality; below 99% is a red flag.
Why do creatine prices vary so much?
Raw material source (China vs Germany), certifications (HASTA, third-party testing), packaging, and marketing spend. A very cheap product usually cuts one of these.
Is Just Creatine banned-substance tested?
Our 1 kg tub is HASTA-certified for banned substances, and every batch is third-party tested for purity and heavy metals.
