Creatine monohydrate, 3 to 5 grams daily, is one of the safest and best-studied supplements available. Its benefits for muscle are well established; its effects on memory, mood, and the menopausal transition are promising but modest and still being defined. In my Echo Park practice, creatine comes up most often with three groups: patients recovering from brain fog or post-viral fatigue, women in perimenopause, and people eating plant-forward diets who start with lower creatine stores. Below, I lay out what the research supports, where it falls short, and who should talk to their physician before starting.
Key Takeaways
Creatine is synthesized in the liver, kidneys, and pancreas from three amino acids and is obtained primarily from animal-based foods; those eating plant-forward tend to have measurably lower stores
Its core mechanism is ATP regeneration, a process relevant to both skeletal muscle and the brain, which has high energy demands and limited local creatine synthesis
A 2024 meta-analysis of 16 RCTs found small but statistically significant improvements in memory and information processing speed in adults taking creatine monohydrate (Xu et al., 2024)
Women tend to have lower baseline creatine stores relative to men, and hormone-driven changes throughout female reproductive life stages alter creatine synthesis, transport, and kinase activity, suggesting supplementation may be of particular importance during menses and the menopausal transition (Smith-Ryan et al., 2021)
Early studies on creatine in women often overlooked menstrual cycle variability; recent research has begun to account for these hormonal fluctuations, meaningfully expanding the clinical picture (Smith-Ryan et al., 2025)
Creatine monohydrate, third-party tested and additive-free, remains the most evidence-supported form; alternative forms carry higher price tags with no demonstrated efficacy advantage
Supplementation is broadly safe in healthy individuals; those with complex medical presentations, such as kidney disease, psychiatric conditions, pregnancy, or multiple medications, should consult a physician before starting
What is Creatine and How Does the Body Utilize It?
Creatine is a naturally occurring compound synthesized primarily in the liver, kidneys, and pancreas from three amino acids: arginine, glycine, and methionine. Approximately 95% of the body's creatine is stored in skeletal muscle, with the remainder distributed in the brain, heart, and other high-energy tissues.
Dietary creatine comes almost exclusively from animal sources, with red meat and fish carrying the highest concentrations. Vegetarians and vegans consistently show measurably lower baseline creatine stores in the published literature, with direct implications for both physical and cognitive supplementation response (Kaviani et al., 2020).
During high-energy demand, the phosphocreatine system regenerates adenosine triphosphate, the cell's primary energy currency, at a rate that other metabolic pathways cannot match. This rapid buffering function is creatine's core value.
In muscle tissue, creatine replenishes ATP faster than other metabolic pathways, sustaining output through high-intensity effort. Because the brain operates under similar energetic pressure and produces creatine locally at limited capacity, researchers are now asking whether the same buffering mechanism produces meaningful effects for its cognitive functions and metabolism.
Performance, Recovery, and Brain Function
The performance literature on creatine is among the most robust in sports nutrition. Creatine supplementation reliably improves output in high-intensity, short-duration efforts, including repeated sprints, resistance training sets, and anaerobic work, by maintaining phosphocreatine availability across efforts. When combined with resistance training, it supports lean mass accrual and improvements in body composition.
Is it Safe?
The safety profile of creatine monohydrate in healthy adults is well-established over decades of research. Kidney damage concerns are not supported by the evidence in healthy individuals. Creatine can temporarily raise serum creatinine, a lab marker often used to estimate kidney function, but a 2025 meta-analysis found no change in glomerular filtration rate, the more direct measure of kidney health (Kabiri Naeini et al., 2025).
Hair-loss concerns trace to a single small 2009 study in rugby players that found a rise in DHT (dihydrotestosterone, a testosterone-derived hormone that can shrink scalp follicles in genetically susceptible people) but never measured hair. A 2025 randomized controlled trial in 38 resistance-trained men, the first to examine hair follicles directly, found no difference between creatine and placebo in DHT levels or hair growth over 12 weeks (Lak et al., 2025). Hair loss should not be presented as an established risk.
Cognitive Performance Under Stress
Emerging research increasingly supports the efficacy of creatine supplementation in enhancing cognitive performance under metabolic strain. By elevating brain creatine concentrations, supplementation bolsters energy homeostasis during states of sleep deprivation or hypoxia (Forbes et al., 2022). A single high dose has even been shown to improve cognitive performance and shift cerebral energy markers during a night of sleep deprivation (Gordji-Nejad et al., 2024). Benefits may be larger in people who start with lower stores, such as vegetarians and vegans.
Creatine and Brain Health
Why the Brain May Benefit from Creatine Supplementation
The brain is an energy-hungry organ that depends on a steady supply of ATP for synaptic function, yet its ability to produce its own creatine is limited. While supplementing can help, the brain is protected by a "gatekeeper" (the blood-brain barrier) that only allows creatine to pass through slowly. Because uptake is slow and tightly regulated, you cannot "load" brain creatine overnight; it requires consistent supplementation over several weeks to see a measurable increase in neural energy stores.
Memory and Processing Speed
A 2024 systematic review and meta-analysis of 16 randomized controlled trials found that creatine monohydrate supplementation produced small but statistically significant positive effects on memory and attention time, as well as improvements in information processing speed. Subgroup analyses found that effects were more pronounced in individuals with underlying health conditions, those aged 18 to 60, and females (Xu et al., 2024). These findings are consistent across a diverse participant pool, though effect sizes are modest and larger trials are needed to confirm them.
Mood and Depression: Mixed but Encouraging Early Evidence
Depression has been linked to disrupted brain energy metabolism, oxidative stress, and neuroinflammation, leading researchers to consider creatine as an add-on to standard treatment (Juneja et al., 2024). Early clinical results are mixed, but two of five small randomized trials in a 2026 review found benefits in specific treatment settings (Jeryous Fares et al., 2026). In one, women with major depression who added 5 grams of creatine daily to escitalopram, a commonly prescribed antidepressant, improved more than those taking escitalopram with a placebo. In another, patients receiving cognitive behavioral therapy improved more when they also took creatine than when they took a placebo (Sherpa et al., 2025). Three other trials, involving treatment-resistant depression, adolescents, and bipolar depression, found no meaningful benefit, and two participants with bipolar disorder developed hypomania or mania, an important safety signal. Creatine should not replace standard treatment, and anyone considering it alongside antidepressants or other psychiatric medication should first consult their prescriber. The evidence is not yet strong enough to recommend creatine for depression, but the positive findings support larger, longer trials into whether it can enhance established therapies for some patients.
Alzheimer's Disease and Brain Injury: An Emerging Area of Research
Both Alzheimer's disease and traumatic brain injury can place substantial demands on the brain's energy systems, making creatine a logical candidate for further study. In the first small clinical trial in Alzheimer's disease, eight weeks of creatine supplementation increased brain creatine levels by approximately 11%, demonstrating that supplementation can alter brain creatine stores in people with the condition (Smith et al., 2025). Whether this translates into improvements in cognition, daily function, or disease progression remains unknown, and the study had no placebo group. Research on traumatic brain injury is at an earlier stage, with much of the evidence coming from animal studies. These findings provide a rationale for further clinical research, but creatine is not an established treatment for either condition. Anyone managing Alzheimer's disease or recovering from a concussion should consult their physician before considering supplementation.
If you've read my article on brain fog and neuroinflammation, creatine offers a natural next step in exploring brain health from a different angle. Acupuncture focuses on regulation, including sleep, stress, and the nervous system's capacity to recover. Creatine is being studied for its role in cellular energy, including the energy demands of the brain. These are different but complementary areas of interest, neither a substitute for appropriate medical care.
Creatine for Women: Hormones, Menstrual Cycle, and Lifespan
Historically, creatine research centered on male athletes, leaving a significant data gap that is only now being corrected. On average, women synthesize about 20% less creatine than men and get 30 to 40% less from their diets (Smith-Ryan et al., 2025). Whether that translates into a larger benefit from supplementation is still an open question, though some early data suggest women may see larger cognitive effects (Xu et al., 2024).
The menstrual cycle adds a layer of biological complexity; fluctuating levels of estrogen and progesterone appear to modulate how the body moves and uses creatine. These hormones influence the expression of arginine-glycine aminotransferase, the "bottleneck" enzyme for creatine production, as well as the activity of creatine transporters (Smith-Ryan et al., 2021). While human trials are still ongoing, the research is promising.
A randomized, double-blind crossover study in 39 women found a significant phase-by-supplement interaction for fatigue index during repeated sprint testing, with the greatest improvement seen in the high-hormone luteal phase among those taking creatine monohydrate compared to placebo. The data suggest creatine monohydrate may help counteract some performance decrements associated with the high-hormone phase (Cabre et al., 2023). Practical phase-specific dosing protocols are not yet standardized, but this is an active and evolving area of inquiry.
Population data from NHANES has also linked creatine intake to menstrual health. Women whose diets met or exceeded recommended creatine intake had 25% lower odds of irregular periods (odds ratio 0.75) than those with lower intake (Ostojic et al., 2024). Because the study was observational and relied on diet recall, it shows an association worth further study, not proof that creatine regulates the cycle.
Perimenopause and Menopause
Dr. Abbie Smith-Ryan (UNC Applied Physiology Laboratory) and colleagues describe perimenopause as a critical period in which creatine may offer meaningful benefits, with potential support for muscle, bone (when paired with resistance training), and cognition (Smith-Ryan et al., 2025). In the CONCRET-MENOPA trial, 36 perimenopausal and menopausal women aged 40 to 60 took one of three low-dose creatine formulations or a placebo for eight weeks. Women taking 1.5 grams daily of creatine hydrochloride showed faster reaction times, and all creatine groups showed higher brain creatine levels. Lipid markers improved in the group taking creatine hydrochloride combined with creatine ethyl ester (Korovljev et al., 2025). The trial was small and did not use creatine monohydrate, so it is an encouraging early signal rather than settled evidence. A placebo-controlled trial in Australia, MENOCOG, is now testing creatine for memory and mood in postmenopausal women experiencing cognitive changes.
Creatine During Pregnancy
Pregnancy represents a distinct clinical context. Animal model data and early human research suggest potential neuroprotective roles for the developing fetus, but this area requires direct obstetric guidance. Supplementation should not be initiated independently during pregnancy.
How to Choose the Best Creatine Supplement and Use It Effectively
Creatine Monohydrate Is the Best-Supported Form
Creatine monohydrate is the most widely studied form of creatine and has been used in the large majority of randomized controlled trials. It carries the longest safety record and costs a fraction of what proprietary blends charge for no demonstrated benefit. Creatine HCl and buffered forms such as Kre-Alkalyn are marketed on claims of superior absorption and reduced GI load; neither advantage is supported by head-to-head efficacy data.
High-Quality, Third-Party Tested Creatine
NSF Certified for Sport, Informed Sport, and USP verification each confirm label accuracy and screen for contaminants and banned substances. Products without independent certification offer no verifiable quality assurance regardless of label language. This standard is non-negotiable for any supplement entering a clinical or performance context.
What to Avoid
Proprietary blends where the creatine dose is undisclosed, formulas stacking creatine with stimulants or undisclosed performance compounds, and products with artificial dyes or excessive additives all warrant skepticism. Complexity in a creatine product rarely signals quality.
How Much Creatine to Take and When to Take It
The standard maintenance dose is 3 to 5 grams daily. While a "loading phase" (20 grams per day for 5–7 days) was once considered the gold standard for saturating muscles quickly, it is optional and can sometimes lead to digestive upset. Ultimately, consistency is the most critical factor; daily intake at any time will lead to full tissue saturation over a period of weeks. Because creatine draws water into the cells, maintaining proper hydration is essential for efficacy.
Because creatine crosses the blood-brain barrier less readily than it enters muscle, brain-targeted dosing may require higher or more sustained intake to produce meaningful cognitive benefits (Candow et al., 2021). Researchers are still working out the right dose for the brain, and no standard has been established yet (Candow et al., 2026). What is clear is that creatine is not a quick fix; consistent daily use over weeks to months is what allows brain levels to build.
Creatine and other supplements can interact with prescription medications. Always discuss any supplement protocol with a prescribing physician before beginning, particularly for those taking diuretics, nephrotoxic medications, anticoagulants, or any medication with a narrow therapeutic window.
Clinical Considerations: Who Should Consult a Professional?
While creatine is among the most well-tolerated supplements for healthy adults and baseline laboratory work is generally unnecessary, certain clinical presentations warrant a prior consultation with a healthcare provider.
Populations Requiring Medical Oversight
Specific individuals should discuss supplementation with their physician or specialist before beginning a protocol. This includes anyone with existing kidney disease or a single-kidney presentation, as well as individuals currently prescribed diuretics or other nephrotoxic medications. Individuals with bipolar disorder should involve their prescriber before starting creatine, as hypomania and mania have been reported in a clinical trial of bipolar depression (Jeryous Fares et al., 2026). Because clinical data remains more limited in these specific populations, those who are pregnant or breastfeeding should also seek medical guidance. Individuals with an active cancer diagnosis or a history of cancer should consult their oncologist first, as laboratory and animal research suggests some tumors may use creatine as an energy source, though this has not been demonstrated in humans (Zhang & Bu, 2022; Rashidi et al., 2024). Finally, a prior consultation is essential for those with a history of disordered eating. In this context, "supplement culture" can serve as a meaningful clinical trigger, and the conversation requires a nuanced, trauma-informed approach to ensure the patient's psychological well-being is prioritized alongside their physical health.
How Creatine Fits Into an Integrative Health Approach
At Golden Mean, creatine may come up as part of a broader nutritional guidance conversation, integrated alongside herbal medicine, acupuncture, and mind-body support based on the individual clinical picture. It is never offered as a standalone recommendation, because substrates do not work in isolation. The system they are entering determines everything.
For patients in Echo Park, Silver Lake, Los Feliz, and the surrounding neighborhoods with questions about supplementation, hormonal health, or cognitive resilience, a formal intake is the right starting point.

FAQ
-
The safety profile of creatine monohydrate in healthy adults, including women, is among the most well-established in the dietary supplement literature. A 2020 systematic review found no meaningful adverse outcomes in female populations across available trials (De Guingand et al., 2020). Long-term use at standard doses is considered low-risk in healthy individuals without contraindications.
-
Creatine draws water into muscle cells, which can produce a modest scale increase during the initial weeks of supplementation.
-
Consistency of daily intake matters considerably more than timing. Creatine taken at any point in the day produces equivalent tissue saturation over time. Daily use without interruption is the primary variable that determines efficacy.
-
Vegans and vegetarians, who lack dietary creatine due to the absence of animal-based foods, may benefit more significantly from supplementation as it restores depleted muscle creatine levels, with potential additional benefits for both physical and cognitive performance (Kaviani et al., 2020). The baseline deficit is consistent and well-documented in the literature.
-
Early research suggests creatine may help buffer some of the energy and performance decrements associated with the luteal phase, and the depression literature, particularly in female populations, shows early promise as an adjunctive approach. These are not yet established clinical protocols. A clinician familiar with the current research can help contextualize individual circumstances.
