TL;DR
Creatine monohydrate is the most researched sports supplement in existence, with over 500 peer-reviewed studies. The effective dose is 3–5 grams per day, taken consistently. It increases strength, lean mass, and high-intensity performance by roughly 5–15% on average, is safe at standard doses in healthy adults, and does not cause hair loss or kidney damage in the research.
What is creatine monohydrate?
Creatine is a naturally occurring compound made from three amino acids — arginine, glycine, and methionine — and stored primarily in skeletal muscle as phosphocreatine. It acts as a rapid energy shuttle, regenerating ATP during short, high-intensity efforts. Creatine monohydrate is the form used in the vast majority of studies showing benefit.
Your body produces roughly 1 gram of creatine per day on its own, and you get another 1–2 grams from meat and fish if you eat them. Supplementing 3–5 grams daily saturates muscle stores above what diet alone typically achieves, and that saturation is what drives the performance and body composition benefits seen in the research.
Vegetarians and vegans typically have lower baseline muscle creatine stores and tend to see larger relative benefits from supplementation than omnivores. Pairing creatine with adequate dietary protein — see our complete guide to whey protein isolate — supports the full muscle-building stack.
How creatine works: the phosphocreatine system
During short, intense efforts lasting under about 10 seconds — a heavy set, a sprint, a jump — your muscles use stored phosphocreatine to regenerate ATP, the body's immediate energy currency. Supplementing creatine increases muscle phosphocreatine stores, extending the duration of peak output and accelerating recovery between efforts.

Creatine dosage: how much per day?
The standard evidence-backed dose is 3–5 grams of creatine monohydrate per day, taken at any time, with or without food. A loading phase of 20 grams per day (split into four 5-gram servings) for 5–7 days will saturate muscle stores faster, but daily 5-gram dosing reaches the same endpoint within about 28 days.
Timing is largely irrelevant for long-term adaptation — what matters is consistency. Missing a day here or there has no meaningful impact once your stores are saturated.
Larger individuals (over roughly 200 lbs) may benefit from the upper end of the range (5 grams) rather than 3 grams, since total muscle mass determines storage capacity. There is no meaningful additional benefit above 5 grams per day for maintenance.
Forms of creatine: monohydrate vs. the alternatives
Creatine monohydrate is the form used in nearly every study showing benefit and remains the gold standard. Alternative forms — HCl, buffered (Kre-Alkalyn), ethyl ester, magnesium chelate, nitrate — are typically marketed as having better absorption or fewer side effects, but no peer-reviewed head-to-head study has shown any alternative form to be more effective than monohydrate.

What micronization actually does
Micronized creatine monohydrate is physically identical to standard monohydrate — same molecule, same absorption — but the particle size is reduced to roughly 1/20th of normal. The practical effect is better solubility in water, less settling at the bottom of your shaker, and fewer reports of GI discomfort in people sensitive to the larger particles. It's the same compound, just easier to drink.
Benefits of creatine: what the research shows
Creatine supplementation consistently improves strength (roughly 5–15%), lean mass (1–2 kg over 4–12 weeks of training), and high-intensity exercise performance. Emerging research also supports benefits for cognition, recovery from injury, and healthy aging, though effect sizes vary and not every outcome is as well-established as the performance data.

Cognition and the brain
The brain, like muscle, relies on phosphocreatine for energy, and growing research suggests creatine supplementation can support cognitive performance — particularly under conditions of sleep deprivation, aging, or mental fatigue. A 2018 systematic review found short-term memory and intelligence/reasoning benefits most consistently. Effects on well-rested young adults in normal conditions are smaller and less consistent.
Aging and sarcopenia
Older adults combining creatine with resistance training show greater gains in lean mass and strength than training alone, which has meaningful implications for preserving independence and reducing fall risk with age. The ISSN position stand lists healthy aging as a well-supported indication for creatine supplementation.
Side effects and safety
Creatine monohydrate is one of the most extensively studied supplements in existence, and at standard doses (3–5 grams per day) in healthy adults, it has not been shown to cause clinically significant side effects in long-term trials. The International Society of Sports Nutrition and multi-year studies lasting up to 5 years confirm its safety profile.
The most commonly reported minor side effects are mild GI discomfort and water retention during the first week of use — both typically resolve or are avoided entirely with micronized monohydrate and taking the dose with food or water.
Does creatine cause hair loss?
There is no direct evidence that creatine causes hair loss. The concern traces back to a single 2009 study in college rugby players that showed a 56% increase in DHT levels after a loading phase — but DHT remained within the normal physiological range, no hair loss was measured in the study, and no subsequent research has replicated the DHT finding or demonstrated hair loss in creatine users.
This is a case where one headline-friendly result has been repeated in supplement discourse for over a decade without replication or any actual outcome data on hair. See our full evidence review on creatine and hair loss for the complete breakdown. If you are genetically predisposed to male pattern baldness, your baseline risk is driven by factors far larger than any plausible creatine effect. The honest summary: the evidence does not support the claim.
Does creatine damage the kidneys?
In healthy individuals, long-term creatine supplementation at standard doses does not harm kidney function. Creatine does raise serum creatinine (a byproduct used to estimate kidney function), which can cause a false alarm on a lab test, but this reflects increased creatine turnover, not kidney damage. People with pre-existing kidney disease should consult a physician before supplementing.
If you are getting routine bloodwork, let your doctor know you supplement creatine so they can interpret your creatinine reading in context, or pause supplementation for a week before the draw.
Who should take creatine?
Anyone doing resistance training who wants to improve strength and lean mass over time.
High-intensity athletes — see our guides for CrossFit and Hyrox athletes — where repeated short efforts are the demand.
Vegetarians and vegans, who have lower baseline muscle creatine stores and often see larger benefits.
Adults over 50 looking to preserve lean mass, strength, and cognitive function.
Women, who typically have lower baseline stores and benefit similarly to men.
People who should check with a physician first: anyone with pre-existing kidney disease, pregnant or breastfeeding women (not because of known risk, but because safety data is limited in these populations), and anyone on medications affecting kidney function.
Frequently asked questions
When is the best time to take creatine?
Timing does not meaningfully affect long-term results. Take it at whatever time you will consistently remember — morning coffee, post-workout shake, with dinner. Consistency matters far more than timing.
Do I need to cycle creatine?
No. There is no physiological reason to cycle creatine. Your body does not downregulate its use, and stopping simply returns muscle stores to baseline over several weeks. Take it continuously.
Does creatine cause weight gain?
Creatine causes a small increase in intracellular water (1–2 kg in the first few weeks), which registers on a scale but is not fat gain. This hydration is a normal and beneficial part of how creatine works in muscle tissue.
Should I take creatine on rest days?
Yes. Creatine works by maintaining saturated muscle stores, not by producing an acute effect around training. Take it every day, including rest days.
Can I take creatine with caffeine?
Yes. Early studies suggested a possible interaction, but more recent research has not replicated any meaningful interference. Taking creatine alongside a pre-workout containing caffeine is fine — and XWERKS Ignite is a clinically dosed option if you want one.
