5 grams of creatine per day is the effective dose for improving muscle mass, strength, power, and endurance across all ages.
A 6-week creatine study showed only 0.86 kg average increase in mass, the majority of which was lean mass, not fat.
Bone benefits from creatine require 8–12 grams per day combined with exercise; creatine without exercise has never been shown to improve bone health.
On average, sedentary people lose about 1% of muscle mass per year after age 40, with strength declining even faster at 1–3% per year.
A study giving 30g of creatine to volunteers sleep-deprived for 21 hours showed it increased brain creatine levels and offset cognitive decline.
The brain weighs about 2 kilograms but consumes 20% of the body's total daily energy at rest.
Vegans and vegetarians respond better to creatine supplementation than meat-eaters because they start with lower baseline creatine stores from their diet.
After stopping creatine, elevated brain creatine levels can persist for 5 weeks to 3 months, while muscle levels take about a month to return to baseline.
Adding 5g of creatine daily to standard antidepressant treatment doubled remission rates in women with major depression over 8 weeks.
The body stores 95% of its total creatine in skeletal muscle, even though creatine is only synthesized in the liver and brain.
Getting just 3 grams of dietary creatine requires consuming a large amount of red meat or seafood, making supplementation a practical alternative.
As little as 3 grams of creatine per day is the lowest effective dose, and taking it consistently for one month will fully saturate skeletal muscle stores.
A study in young female athletes found they slept an average of 1 hour longer on training days when taking creatine compared to a placebo.
Testing of off-the-shelf creatine products found that approximately 90% contained little to no actual creatine, underscoring the importance of third-party testing.
A 2024 study reviewing over 25,000 cases confirmed creatine is safe and effective even at doses above 10 grams per day taken over many years.
Creatine doesn't damage kidneys, cause hair loss, make you bloated long-term, or cramp your muscles. It's not only for men. Every one of these widely-held myths is contradicted by randomised controlled trial evidence.
A rested brain makes enough creatine on its own. But sleep deprivation, time zone shifts, exam pressure, and high-stakes performance all create metabolic stress that depletes brain creatine faster than it can be synthesised. At 20–30g acutely, supplementation crosses the blood-brain barrier and partially restores cognitive performance.
Adding 5g of creatine to a standard antidepressant doubled remission rates in women with major depression over 8 weeks. People with depression consistently show lower baseline brain creatine, and supplementation appears to restore the bioenergetics that underlie mood regulation.
Muscle needs 5g, bone needs 8–12g with exercise, and a stressed brain may need up to 20–30g acutely. Taking 10g daily covers muscle and bone and provides a reasonable buffer for the brain — making it the practical all-round dose for most people.
Twenty Alzheimer's patients who took 20g of creatine daily for 8 weeks showed an 11% increase in brain creatine levels and significantly improved cognitive test scores. Creatine reduced inflammation, improved brain bioenergetics, and may offer neuroprotective effects.
Creatine is found exclusively in animal flesh. Vegans and vegetarians synthesise about 1–3g daily through amino acids but get none from food, meaning they start with the lowest stores and respond the most dramatically to supplementation.
In a landmark study, participants given 20g of creatine before a 90-minute Stroop test — where you must name ink colours while reading conflicting colour words — showed statistically significant improvements in both speed and accuracy. The Stroop test is one of the most cognitively fatiguing tasks used in creatine research.
Weight training provides almost all the cardiovascular benefits of aerobic exercise while additionally building muscle mass, improving VO2 max, and boosting mitochondrial health. If you have to choose one, choose resistance training — but do both.
On average, people lose 1% of muscle mass per year after 40, and strength declines even faster at 1–3% annually. Resistance training is the only proven modality that halts this progression. Without it, the slope becomes catastrophic by age 80.
20 grams of creatine for 5 days before long-duration events like Ironman triathlons reduced inflammation markers in participants. This anti-inflammatory and anti-catabolic effect may allow faster recovery and better subsequent performance.
Animal studies show that taking creatine before head trauma significantly speeds up concussion recovery. Dr. Candow argues anyone in contact sports — boxers, UFC fighters, rugby players — should be taking creatine as a prophylactic neuroprotective measure.
In a study from Dr. Candow's lab, healthy young female athletes slept an average of 1 hour longer on training days when taking creatine versus placebo. If replicated in males, this could be one of creatine's most universally appealing benefits.
Taking creatine in smaller doses spread throughout the day eliminates GI discomfort, dizziness, and water retention issues that can occur with large single doses. One study showed that 1 gram every 30 minutes up to 20 grams retained more creatine in the body.
Estrogen is directly involved in the enzymes that synthesise creatine and in both brain and muscle bioenergetics. As estrogen falls during perimenopause and menopause, creatine supplementation may help offset accelerated losses in muscle, bone, and cognitive function.
A YouTuber's product testing found 90% of off-the-shelf creatine products contained little or no creatine. Dr. Candow's three-point checklist: look for creatine monohydrate, CreaPure certification from Germany, and an NSF or third-party certification logo.
