The short answer
Creatine monohydrate can make sense for a cyclist who strength trains or repeatedly needs brief high-power efforts. It does not improve pooled endurance performance in trained people, and it is not a guaranteed FTP, recovery, cognition or sprint upgrade.
The strongest evidence is for creatine alongside resistance training. The direct endurance evidence is much less compelling. Body mass can increase, so the decision depends on the rider, event and outcome—not on the claim that every cyclist should take it.
Your creatine decision in 60 seconds
| Situation | What the evidence says | Starting decision |
|---|---|---|
| You complete progressive strength training | Strength and lean-mass evidence is the strongest use case | Reasonable to consider after the programme and nutrition are in place |
| Your racing includes repeated sprints or surges | Selected high-intensity findings are promising but inconsistent | Test one defined high-power outcome and body mass |
| You want more FTP or steady endurance | Trained-endurance meta-analysis was null | Do not buy creatine for that promise |
| You are a masters rider | Older-adult strength evidence is positive but indirect for cycling | Consider beside resistance training, not because of age alone |
| A steep weight-sensitive event is the priority | Body mass can rise and the individual response varies | Trial well before the event and calculate the actual trade-off |
| You want a brain or late-race decision benefit | Reviews conflict; EFSA did not establish cause and effect | Do not make cognition the guaranteed reason to buy |
| You have kidney disease, pregnancy, medication or another health concern | Healthy-adult safety evidence cannot answer every medical case | Use individual clinical advice |
What creatine does—and what that does not prove
Creatine helps replenish phosphocreatine, which supports rapid ATP resynthesis during brief, high-intensity muscular work. Supplementation can increase muscle creatine stores, giving a clear mechanism for strength training and repeated maximal efforts.
But a mechanism does not settle a cycling outcome. A road race combines steady aerobic work, short surges, handling, tactics, fuelling and fatigue. Increasing one energy buffer does not automatically raise FTP, make a rider more economical or improve the final sprint after five hours.
Use mechanism to identify a plausible question. Use controlled outcomes to decide whether the answer is established.
Does creatine improve endurance cycling performance?
The most direct pooled answer is no.
A 2023 systematic review and meta-analysis included 13 placebo-controlled studies of creatine monohydrate in trained participants. Creatine did not significantly improve endurance performance in the pooled analysis.
That is the most important boundary on this page. It means creatine should not be presented as a direct way to:
- raise FTP;
- improve a steady 20-minute climb;
- ride a time trial faster;
- increase VO2max; or
- make sub-threshold endurance work more economical.
A 2024 systematic review of nutritional aids in cycling also illustrates how limited the clean, standalone cycling evidence is compared with the huge general creatine literature.
Creatine can still help the gym work that supports a cyclist, or a high-intensity demand inside an endurance event. That is a narrower and more defensible claim.
What about sprints, attacks and repeated surges?
A 2026 scoping review of endurance and mixed-sport contexts found the most plausible use in selected repeated-sprint, surge and power-endurance settings. It also found inconsistent results across performance, recovery and body-composition outcomes.
That distinction matters. The supplement has strong evidence for short high-intensity work across broader sport and resistance-training research. The exact cycling questions—final sprint after a long race, repeated attacks, closing a gap, accelerating out of corners—have a smaller and less consistent direct evidence base.
For a crit, track or repeated-surge rider, creatine is reasonable to test. Predefine the measure:
- repeated 6–10-second sprint power under the same conditions;
- quality across a fixed high-power interval set;
- a consistent gym lift; and
- morning body mass and gastrointestinal tolerance.
Do not use one exceptional power file as proof. Day-to-day freshness, calibration, weather, motivation and training change power too.
Creatine and strength training for cyclists
This is the strongest section of the case.
A 2024 meta-analysis in adults under 50 included 23 studies and found that creatine plus resistance training improved pooled upper- and lower-body strength compared with placebo plus resistance training. Only 49 of the 509 participants were women, so representation remains a major limitation.
A separate 2024 body-composition meta-analysis found that creatine added to resistance training increased lean body mass by an average of 1.14 kg compared with resistance training alone. That result belongs to a resistance-training context; it should not be renamed “cycling muscle” or a direct performance gain.
The useful sequence is:
- build a progressive, recoverable strength programme;
- perform it consistently;
- meet energy and protein needs;
- decide whether creatine is worth testing; and
- measure gym and body-mass outcomes before claiming transfer to the bike.
The cycling strength-training guide covers the intervention. Roadman’s strength-session planner helps place the work before a supplement enters the discussion.
Should masters cyclists take creatine?
Masters riders have a reasonable case to consider creatine, especially when resistance training is already part of the week. “Every cyclist over 40 should take it” is still too strong.
A meta-analysis of 22 trials and 721 older adults found that creatine added to resistance training increased lean tissue and selected upper- and lower-body strength outcomes. The mean ages across included studies ranged from 57 to 70.
That is useful evidence for healthy ageing and strength. It is not a trial of 40-year-old cyclists, and it does not prove a faster climb, sprint or sportive. The age boundary matters because “masters cyclist” begins much earlier than the populations in many ageing studies.
The right masters position is: protect strength with training, then consider creatine as an optional aid to that training.
Dose: maintenance or loading
The Australian Institute of Sport guidance describes two practical routes using creatine monohydrate.
Maintenance only: 3–5 g/day. This raises stores more gradually and avoids a high-dose loading week.
Loading then maintenance: about 0.3 g/kg/day, divided across roughly four servings for about five days, followed by 3–5 g/day. This reaches saturation faster.
Loading is faster, not mandatory. A review of common creatine questions also supports smaller daily doses without a loading phase.
There is no established need to cycle on and off to keep creatine “working.” Stopping can be an event-specific body-mass decision, not a physiological reset requirement.
Does timing matter?
Consistency matters more than a precise clock time. The evidence does not establish one compulsory post-workout minute for cyclists.
Choose a repeatable time, use the same product and dose, and make gastrointestinal tolerance easy to observe. Taking it with a meal can be practical. If loading, divide the larger daily amount as guidance suggests rather than taking it in one hit.
Creatine does not replace carbohydrate after a depleting ride, protein across the day or fluid matched to actual losses.
Weight gain and climbing
The claim that everybody gains exactly 1–2 kg is too certain.
A 2024 meta-analysis of 143 randomized studies found an average body-mass increase of 0.86 kg and fat-free-mass increase of 0.82 kg. Response varied by protocol and training context. AIS guidance notes that some athletes can gain around 1–2 kg, with faster initial change more relevant during loading.
Body-composition methods can also count water as lean mass. A short-term scan or smart scale does not prove new contractile muscle.
For climbing, use the actual maths. If body mass rises but sustainable power does not, watts per kilogram falls. If gym strength or repeated high-power work improves, that may still be valuable for another event. Neither trade-off is universal.
If you stop creatine, AIS guidance describes muscle creatine and associated body mass declining gradually toward baseline over roughly four to six weeks. Test that timing before the event that matters rather than assuming one week is enough.
Anthony’s 30-day creatine self-test
Anthony reported taking 5 g/day for 30 days without loading. His logged result was about 1.5 kg higher body mass, roughly 5% higher five-second sprint power and no meaningful FTP change.
That is useful first-party reporting because it shows a real cyclist’s protocol and trade-off. It cannot establish causation:
- there was one participant;
- there was no placebo or blinding;
- normal training and learning effects were not controlled;
- peak power varies naturally; and
- the result may not reproduce in another rider.
The right use of the experiment is as a template for transparent measurement—not proof that 5 g/day adds 5% to cyclist sprint power.
The accompanying podcast episode preserves the conversation and subjective experience.
Does creatine improve cognition?
The evidence is mixed, and cyclist-specific claims run ahead of it.
A 2024 meta-analysis of 16 trials reported small improvements in memory and selected timed outcomes, with no significant improvement in overall cognition or executive function. Certainty was moderate for memory and low for several other domains.
Another 2024 systematic review described cognitive findings as equivocal. The European Food Safety Authority assessment concluded that a cause-and-effect relationship between creatine supplementation and improved cognitive function had not been established.
None of these sources proves better wheel choice, reaction time or tactical decisions in the final hour of a cycling event. Cognition should not be the guaranteed headline benefit.
Do professional cyclists take creatine?
Some professional riders and performance teams use creatine; others may avoid or periodise it around event demands. Professional use is not controlled evidence, and team practice is not one universal protocol.
The relevant question is why a specific rider uses it:
- supporting a gym block;
- repeated sprint or track demands;
- rehabilitation or lean-mass goals;
- an individual nutrition plan; or
- a coach or practitioner’s experiment.
Copying the product without the job and monitoring does not copy the decision.
Safety, kidneys, cramps and hydration
The established review literature does not support creatine monohydrate at recommended doses causing kidney damage, dehydration or muscle cramps in healthy adults. It also does not make an article capable of clearing every individual.
Use a qualified clinician or pharmacist when kidney disease, pregnancy, medication, unexplained symptoms or another health condition changes the decision. Tell the clinician who interprets kidney-related blood tests that you use creatine, because supplementation can affect creatinine-related interpretation without that alone proving kidney damage.
Stop and investigate persistent gastrointestinal symptoms or another unexpected reaction. Normal hydration remains necessary; creatine is not a heat plan.
Which creatine should cyclists buy?
Choose plain creatine monohydrate, the form used across the established evidence base.
Use this checklist:
- the label states the amount of creatine monohydrate per serving;
- there is no proprietary blend hiding the dose;
- batch, manufacturer and contact information are clear;
- the product does not rely on claims that another form is “more absorbable” without comparative outcome evidence; and
- competitive riders use an appropriate independent sport batch-testing programme.
Creatine itself is not the contamination problem. A poorly controlled supplement can contain an undeclared prohibited substance, and anti-doping responsibility sits with the athlete.
Where creatine fits in the Roadman app
The supplement question only becomes useful when it connects to the rider’s actual week: strength sessions, high-power work, recovery, body mass and the next event.
Roadman is building a cycling strength and recovery app to make those connections explicit. It will not prescribe creatine to every cyclist. It will help riders identify whether the current goal is strength, repeated power, endurance, recovery or body-mass management—and whether a supplement experiment has a measurable job.
A practical creatine decision
Consider creatine when:
- a real resistance-training or repeated-high-power goal exists;
- you are willing to use monohydrate consistently;
- body mass and tolerance can be measured; and
- the evidence trade-off fits the target event.
Skip or postpone it when:
- the promised outcome is FTP or steady endurance;
- the strength programme does not yet exist;
- a weight-sensitive event is too close for a proper trial;
- health context needs individual clearance; or
- the product cannot demonstrate basic quality control.
Creatine is one of the best-supported sports supplements. The strongest version of that sentence is still not “every cyclist should take it.”
