Creatine boosted strength and power in vegan adults

Key Takeaways

• In 20 physically active vegan adults, 4 weeks of creatine monohydrate improved measures of strength and lower-body power versus placebo.
• The creatine group also gained 0.3 kg of skeletal muscle mass and 1.4 kg of total body water, while body fat fell by 1.4 kg compared with controls.
• The dose was 0.1 g per kg of body weight per day, which is a moderate daily protocol rather than a classic loading phase.
• Because the trial was small and lasted only 4 weeks, it supports short-term performance benefits but cannot settle long-term effectiveness or safety in vegans.
• For vegan athletes and gym-goers, the study strengthens the case for plain creatine monohydrate as the first form to consider.

What the study found

A new trial in the European Journal of Applied Physiology reports that creatine monohydrate improved strength and lower-body power in physically active adults who followed a vegan diet for four weeks. That is the core news, and it matters because vegan diets contain little to no preformed creatine from food.

The study enrolled 20 vegan adults aged 18 to 45 and randomly assigned them to creatine or placebo. After four weeks, the creatine group showed significant increases in skeletal muscle mass, total body water and BMI, along with a reduction in body fat compared with controls. The reported changes included:

• +0.3 kg skeletal muscle mass
• +1.4 kg total body water
• +0.3 kg/m² BMI
• -1.4 kg body fat versus controls

On performance testing, the authors concluded that creatine enhanced muscle strength and lower-body muscular power. The abstract names the tests used, including countermovement jump, sprint, repeated jumps, handgrip strength and the isometric mid-thigh pull, but the abstract does not provide the full numerical results for each test. That means we can accurately say performance improved overall, but we should avoid claiming a specific benefit for any one test unless the full paper shows it.

For readers deciding whether creatine is worth trying, this is a practical result. It suggests that even without a loading phase, a moderate daily dose of creatine monohydrate can produce measurable short-term changes in performance and body composition markers in active vegans.

Why vegans may respond differently to creatine

The biological rationale here is straightforward. Creatine is found naturally in animal foods, especially meat and fish. People eating vegan diets do not get those dietary sources, so their baseline muscle creatine stores may be lower on average. If starting stores are lower, supplementation can have more room to raise intramuscular creatine and phosphocreatine, which may translate into bigger gains in high-intensity performance.

This does not mean every vegan is automatically deficient, nor that every omnivore has fully saturated stores. It does mean vegan status is a plausible reason to expect a solid response to supplementation, especially for repeated high-power efforts, resistance training and explosive work.

That broader idea is consistent with the mainstream creatine literature. The best-supported form remains creatine monohydrate, and the best-supported outcomes remain improvements in high-intensity exercise capacity, training quality and lean mass over time. The International Society of Sports Nutrition position stand concludes that creatine monohydrate is both effective and well studied across athletic settings, while a later review addressing common misconceptions reinforces that monohydrate is still the benchmark form. Readers can explore those wider summaries in Kreider et al. (2017) and Antonio et al. (2021).

So the novel part of this study is not that creatine works in principle. It is that this specific four-week trial directly tested active vegan adults and found the expected performance signal in that population.

How the trial was designed and what that means

This was a randomized, triple-blind, placebo-controlled trial, which is a strong design for testing a supplement. Randomization helps balance groups. Placebo control helps separate a real supplement effect from expectation. Triple-blind generally means participants, investigators and outcome assessors were blinded, reducing several common sources of bias.

The study included 20 physically active vegan adults, with equal numbers of females and males in each group. Participants were assigned to either creatine monohydrate or placebo while following a normocaloric vegan diet. The creatine dose was 0.1 g/kg/day for four weeks. Outcomes included body composition, multiple performance tests and renal biomarkers.

Those are meaningful strengths. But there are also important limitations:

• Small sample: 20 participants is enough to detect some effects, but it limits precision and makes results more vulnerable to random variation.
• Short duration: four weeks can show early performance changes, but not the full training adaptations or longer-term safety picture.
• Abstract-only detail: the supplied abstract does not give full numerical outcomes for each performance test, so readers should not infer more specificity than the paper reports.
• Specific population: these were physically active vegans aged 18 to 45, not sedentary adults, older adults, or elite athletes as a whole.

In short, the design is better than many supplement studies, but the sample and duration mean this should be read as good evidence of short-term benefit in this population, not the final word on every vegan athlete.

What it means in practice for creatine users

If you follow a vegan diet and do resistance training, sprint work, jumping, team sport or other high-intensity exercise, this study gives you a reasonable evidence-based nudge toward creatine monohydrate. The dose used here was 0.1 g per kg per day. For many adults, that lands in the same general range as common real-world dosing.

In broader sports nutrition practice, the standard maintenance approach is 3 to 5 g/day of creatine monohydrate. A classic loading option is about 20 g/day split into 4 doses for 5 to 7 days, followed by maintenance. Loading helps saturate stores faster; it is not required for creatine to work. This trial is a useful reminder that a steady daily intake can still produce meaningful effects in a month.

Practical tips:

• Choose plain monohydrate before paying extra for exotic forms.
• Take it daily rather than worrying too much about exact timing.
• Expect some increase in body water as muscle creatine stores rise.
• Use a bodyweight-based or standard daily dose consistently.

If you want help estimating a sensible intake, a creatine dosage calculator can make the bodyweight math easier. If you are comparing products, see our creatine product catalog, creatine brand reviews and broader creatine guides.

For healthy people, creatine monohydrate is generally considered safe in the evidence base, but anyone with known kidney disease or a relevant medical condition should speak with a clinician first.

How this fits the bigger creatine evidence

This study fits neatly into what sports nutrition researchers already know. Creatine monohydrate is one of the most studied and most consistently effective supplements for high-intensity exercise performance. Across the wider literature, it tends to help with repeated sprint ability, strength, power output and lean mass gains when paired with training.

What this trial adds is population-specific evidence. Vegan athletes and recreational lifters are often told they may respond well to creatine because they do not consume dietary creatine from animal foods. That claim has been plausible for years, but direct randomized evidence in active vegan adults has been limited. This paper helps close that gap.

It also reinforces a point that gets lost in marketing: the relevant question is usually not whether a trendy form is better than monohydrate, but whether plain monohydrate already does the job. For most people, it does. That is why monohydrate continues to dominate the evidence base and why it tops most serious best creatine rankings.

Still, context matters. The study does not prove that every vegan will see dramatic changes in four weeks, nor that creatine will improve every type of performance equally. It supports a likely average benefit in a specific group under controlled conditions. That is exactly the kind of incremental, useful evidence readers should want: not hype, but a better estimate of who benefits and how much confidence we should have.

Bottom line

The bottom line is simple: this small but well-controlled trial found that four weeks of creatine monohydrate improved strength and lower-body power in physically active vegan adults. It also increased skeletal muscle mass and total body water, which is consistent with how creatine typically works.

For people on a vegan diet, that result is especially relevant because baseline creatine intake from food is minimal. If you train hard and want a supplement with a strong evidence base, plain creatine monohydrate remains the first option to consider.

Just keep the study in perspective. It involved only 20 participants, lasted four weeks and the abstract does not provide every performance detail. So this is best read as encouraging evidence, not a sweeping proof that creatine transforms performance in all vegans under all conditions.

In practical terms, the take-home message is conservative and useful:

• Creatine monohydrate appears to help active vegans with short-term strength and power outcomes.
• A daily protocol can work even without a formal loading phase.
• Monohydrate remains the evidence-based default form.
• Longer and larger studies are still needed.

That is a good news story for vegan trainees, and a reminder that the most reliable supplements are usually the least flashy ones.
