Why Creatine Is Suddenly Everywhere
For most of its commercial life, creatine belonged to one small corner of the supplement world. Athletes and bodybuilders discovered its benefits in the early 1990s, and supplement companies built products around muscle development for that narrow audience. Speaking at an industry conference on creatine, Dr. Batzler of the German producer AlzChem Group noted that for roughly 25 years, marketing rarely looked beyond that demographic. That era is ending. Creatine is now studied in the context of healthy aging, cognition, fatigue, and, most relevantly for this article, plant based nutrition.
The reason vegans and vegetarians sit at the center of this shift is simple: creatine is found naturally only in animal derived foods, chiefly meat and fish. As Batzler explains, people who eat a plant based diet consume essentially no creatine at all, and a substantial body of research shows their body stores run measurably lower than those of omnivores. That raises a practical question worth answering carefully rather than promotionally: do vegans and vegetarians actually need creatine, what does supplementation change, and where does the evidence stop?
What Creatine Is and What It Does
Creatine is a compound the human body makes on its own, primarily in the liver and kidneys, from the amino acids glycine, arginine, and methionine. Around 90 to 95 percent of it is stored in skeletal muscle, with the rest distributed across other energy hungry tissues, including the brain.
Its job is energy logistics. In its high energy form, phosphocreatine, it acts as a rapid buffer for adenosine triphosphate, or ATP, the molecule that powers muscle contraction and cellular work. When a cell burns through ATP during an intense effort, phosphocreatine donates its phosphate to regenerate ATP almost instantly, far faster than the slower aerobic and glycolytic pathways can manage. Batzler describes phosphocreatine as a spatial energy buffer that matters not only in muscle but in brain cells and other tissues with sudden energy demands. He also cites specific figures, stating that ATP regeneration via phosphocreatine runs about 40 percent faster than through the respiratory chain and about 10 percent faster than through glycolysis. The general principle is textbook physiology, but I could not verify those exact percentages in independent literature, so treat the numbers as the speaker’s own framing rather than an established constant.
Omnivores typically take in about 1 to 2 g of creatine daily from meat and fish, on top of roughly 1 g of internal production. Someone on a fully plant based diet gets close to zero from food. Their body still synthesizes creatine, but total availability sits lower, and that difference shows up in tissue measurements.
The Creatine Gap in Plant Based Eaters
The claim that vegetarians and vegans carry lower creatine stores is one of the best supported points in this entire topic. Direct muscle biopsy evidence comes from a trial by Burke and colleagues published in Medicine and Science in Sports and Exercise, which measured total muscle creatine of about 117 mmol per kilogram in vegetarians versus about 130 in nonvegetarians, a statistically significant gap. A 2020 systematic review by Kaviani, Shaw, and Chilibeck, covering nine studies, confirmed that vegetarians show lower creatine concentrations in muscle, plasma, and red blood cells.
Perhaps the most elegant evidence is a randomized trial by Blancquaert and colleagues in the British Journal of Nutrition. Omnivorous women were switched to a vegetarian diet, and within three months their muscle total creatine had fallen by about 14.6 percent unless they received a small creatine supplement. The authors calculated that roughly 1 g of creatine monohydrate per day was enough to prevent the decline. In other words, the drop is not a quirk of who chooses vegetarianism; removing dietary creatine directly lowers the body pool.
One important nuance complicates the simple story, and an honest article has to include it. Batzler presents lower creatine levels in vegetarians as a general fact, and for muscle and blood that is accurate. The brain appears to be different. Solis and colleagues used magnetic resonance spectroscopy to compare brain creatine in vegetarians and omnivores and found essentially identical levels, despite dietary intakes of 0.03 versus 1.34 g per day. The brain seems to rely largely on its own local synthesis and guards its creatine content tightly. Later work by the same group found that a week of supplementation raised muscle creatine in vegetarians but did not change brain creatine at the dose tested. So the “creatine gap” is real, but it is primarily a muscle and blood phenomenon, not a demonstrated brain deficit.
What Supplementation Actually Changes
For muscle, the evidence is strong and consistent. According to Batzler, supplementation increases total creatine concentrations in muscle, plasma, and red blood cells, and the independent research agrees. The 2020 systematic review found that supplementing vegetarians raised their creatine and phosphocreatine levels, often to concentrations matching or exceeding those of omnivores.
More interesting is that people starting from lower baselines tend to gain more. In Burke’s trial, vegetarians who supplemented while resistance training saw greater increases in phosphocreatine, total creatine, type II muscle fiber area, lean tissue mass, and total work performed than omnivores following the identical protocol. The review echoed this, reporting improvements in strength, muscular endurance, and Wingate mean power output among vegetarian participants. The pattern makes intuitive sense: a fuller tank helps most when the tank started emptiest.
The International Society of Sports Nutrition, in its position stand authored by Kreider and colleagues, concludes that creatine monohydrate is the most effective nutritional supplement available for increasing high intensity exercise capacity and lean body mass during training. Regulators have been more conservative but still supportive. The European Food Safety Authority assessed the evidence in 2011 and authorized the claim that creatine increases physical performance in successive bursts of short duration, high intensity exercise, at a daily intake of 3 g. Batzler mentions this claim in his talk. He does not mention that a second EU claim was later approved, covering creatine combined with resistance training for muscle strength in adults over 55, while eleven other proposed claims, including improved mental attentiveness, were rejected for insufficient evidence. That regulatory scorecard is a useful reality check: the exercise performance effect is established; many of the broader claims are not, at least not yet to a regulator’s standard.
How Much to Take, and Whether Loading Matters
Batzler recommends 3 to 5 g per day and states that no loading dose is required, which matches the mainstream scientific position. Older protocols used a loading week of around 20 g per day to saturate muscle quickly, and that works, but the ISSN notes that a steady 3 to 5 g daily reaches the same saturation point over roughly four weeks. For anyone not facing a competition deadline, the simple daily dose is enough. People with lower starting stores, including vegans and vegetarians, may simply notice the benefits somewhat sooner or more strongly.
He also states that creatine does not accumulate in the body because it is excreted through urine. That is broadly right but worth phrasing precisely: muscle stores do rise with supplementation and then plateau at a saturation ceiling, and surplus creatine is converted to creatinine and passed out in urine. On safety, the evidence base is unusually deep for a supplement. The ISSN position stand reports that studies using up to 30 g per day for as long as five years found supplementation safe and well tolerated in healthy people and in a range of patient populations. Creatine monohydrate is synthesized rather than animal derived, so standard creatine monohydrate powder is itself suitable for vegans, though anyone buying capsules should check that the shell is not gelatin.
Creatine and the Brain: Promising, Not Proven
The most commercially exciting territory for creatine right now is cognition, and it is also where honesty matters most. Batzler lists improved cognition, protection of the central nervous system, reduced fatigue, and even a reduced need for sleep among creatine’s benefits. The research supports some of this, partially, and not all of it.
On memory and reasoning, a 2018 systematic review of randomized controlled trials by Avgerinos and colleagues concluded that creatine may improve short term memory and intelligence or reasoning in healthy people, while effects on other cognitive domains remain unclear. Notably for this article, the review found vegetarians responded better than meat eaters on memory tasks. A 2024 meta analysis in Frontiers in Nutrition pooled the trials and found a statistically significant improvement in memory, though the effect size was modest. Individual studies fill in the picture: Benton and Donohoe gave 128 young women creatine or placebo and found memory improvements in the vegetarians but no effect on verbal fluency or vigilance, and the well known trial by Rae and colleagues found working memory and abstract reasoning gains in young vegetarian adults.
At the same time, a 2024 systematic review in Behavioural Brain Research concluded that the overall cognitive evidence is equivocal, noting that brain creatine rises only modestly with supplementation and that many trials are small. So the fair summary is this: creatine for cognition is promising, with the clearest signals in memory, in older adults, in people under physiological stress, and possibly in vegetarians, but it is not an established effect the way the muscle performance benefit is. Remember too that vegetarians do not appear to have depleted brain creatine in the first place, which may explain why cognitive findings are less consistent than muscle findings.
The sleep and fatigue claims deserve their own scrutiny. A striking 2024 study by Gordji-Nejad and colleagues in Scientific Reports gave participants a single large dose of creatine, 0.35 g per kilogram of body weight, during 21 hours of sleep deprivation. Brain scans showed better preserved high energy phosphate levels, and participants performed better on processing speed and memory tasks than those on placebo. A 2025 follow up found similar cognitive protection at a lower dose of 0.2 g per kilogram. This is genuinely interesting evidence that creatine can buffer some of the cognitive cost of a sleepless night. It is not evidence that creatine reduces the need for sleep, as the phrasing in Batzler’s talk suggests, and no study supports using it as a sleep replacement. On mood, the evidence remains preliminary.
Creatine and Healthy Aging
Batzler argues that creatine can help people live better as they age, framing the goal as bending the aging curve to extend healthy lifespan. Strip away the marketing language and there is solid science underneath, with one crucial condition attached: the strongest aging evidence involves creatine combined with resistance training, not creatine alone.
Muscle mass and strength decline with age, a process that can progress to sarcopenia, with real consequences for independence and fall risk. A meta analysis by Chilibeck and colleagues covering 22 randomized trials and 721 older participants found that adding creatine to a resistance training program produced about 1.37 kg more lean tissue mass and greater upper and lower body strength than training with placebo. A 2021 meta analysis in Nutrients and subsequent reviews broadly confirm the effect, while noting the gains are small to moderate and that dosing strategy may matter. This body of evidence is what persuaded EFSA to approve the over 55 claim, which specifies at least 3 g daily alongside resistance training performed at least three times a week at moderate intensity.
For older vegetarians and vegans, the logic compounds: they enter later life with lower muscle creatine stores and stand to gain the most from restoring them, but the training component is not optional if the goal is stronger muscles. Beyond muscle, Batzler mentions emerging areas including glucose management, heart metabolism, immune cell activity, and skin health. These are best described as early stage research. Creatine’s role in immune cell energy metabolism is mechanistically plausible and under active study, but human outcome trials are lacking. For skin, small studies of topical creatine formulations have reported increased collagen synthesis and reduced wrinkle measures, and a 2025 review in the Journal of Clinical and Aesthetic Dermatology found the clinical evidence limited, often industry linked, and in need of independent replication. None of these areas justifies health claims today, and Batzler himself notes that several such claims remain only in the regulatory pipeline.
Creatine in Food: The Functional Food Frontier
The most distinctive part of Batzler’s presentation concerns where creatine will live on the shelf. His prediction is that creatine will move beyond tubs of powder into everyday foods, especially foods aimed at vegetarians and vegans, and that shoppers will see creatine enriched products in grocery stores in the near future. He describes adding creatine to yogurt, cereals, muesli, bars, confectionery, baked goods, and, most pointedly, plant based burger patties, where a vegetable protein matrix is built with texturizers, spices, and flavor and then enriched with creatine to bring its nutritional profile closer to meat.
He supports this with stability data from his company’s laboratories: in yogurt, creatine content held up through fermentation, heating, and days of storage with only around a ten percent loss, and in burger patties, high creatine content survived a two step cooking process of pre frying followed by steam oven cooking. These findings are plausible, but they are internal company studies presented at a conference, and I found no independent peer reviewed replication, so they should be read as a manufacturer’s data rather than settled food science.
The sustainability argument he attaches to this trend does check out at the headline level. Batzler states that the food system is responsible for up to 35 percent of global emissions, with animal products contributing up to 15 percent. The landmark analysis by Crippa and colleagues in Nature Food estimated that food systems generated 34 percent of global anthropogenic greenhouse gas emissions in 2015, with a plausible range of 25 to 42 percent, which matches his figure. The connective logic is straightforward: if more people shift toward plant based eating for climate reasons, more people will have near zero dietary creatine intake, and fortified foods or supplements become the practical way to close the gap. It is worth being transparent that this is also a commercial thesis. Batzler represents AlzChem, which trade press confirms is the only creatine monohydrate producer outside China, manufacturing its Creapure brand in Trostberg, Germany, and which announced an expansion of its creatine capacity scheduled to come online in 2022 precisely because of this anticipated demand. The market interest does not make the underlying science wrong, but readers should know the vantage point.
The Bottom Line for Plant Based Eaters
Pulling the verified evidence together: vegans and vegetarians reliably carry lower creatine stores in muscle and blood than omnivores, because food creatine comes only from animal products and internal synthesis does not fully compensate. Supplementing 3 to 5 g of creatine monohydrate daily restores those stores, is exceptionally well studied for safety, and produces meaningful gains in high intensity exercise performance, strength, and lean mass, with vegetarians often responding more strongly than meat eaters. For older adults, creatine amplifies the benefits of resistance training on muscle and strength, an effect solid enough to earn EU regulatory approval.
The brain story is more tentative. Vegetarians do not appear to have depleted brain creatine, and while trials suggest possible memory and reasoning benefits, especially under stress or sleep deprivation, the cognitive evidence remains mixed and the effects modest. Claims about immunity, skin, glucose, heart health, or reduced sleep need run well ahead of the data. Creatine is not a requirement for health on a plant based diet; the body’s own production prevents outright deficiency. It is better understood as a low cost, low risk way for plant based eaters to reclaim a performance and possibly cognitive resource that their diet, for good ethical and environmental reasons, leaves off the plate.
