Creatine monohydrate helps regenerate ATP during brief, high-energy work. In this clip from Dr. Rhonda Patrick's appearance on The Dan Bongino Show, she explains how increased phosphocreatine availability can support training volume, strength, and lean-mass adaptations. A daily dose of 3 to 5 grams generally raises muscle creatine stores over three to four weeks, while an optional loading phase of approximately 0.3 grams per kilogram per day can accelerate saturation. [1]
Brain uptake is smaller and more variable than muscle uptake. In a small spectroscopy study, six healthy adults who took 20 grams per day for four weeks had an average increase in measured brain creatine across selected regions. Research in healthy, rested adults has produced mixed cognitive results, which makes energetic stress an important setting for studying whether creatine's support for cellular energy becomes more noticeable. [2] [3]
Severe sleep deprivation offers one such model. In a randomized crossover study of 15 healthy young adults, a single dose of 0.35 grams per kilogram changed brain-energy measures and reduced deterioration on selected cognitive tasks during about 21 hours awake. A later 29-person study using 0.2 grams per kilogram found its clearest benefit in reasoning, with mixed results across other measures. These acute research doses inform the study of brain energy under sleep loss, while 3 to 5 grams remains the best-established routine dose for muscle benefits. [4] [5]

Dr. Rhonda Patrick: Creatine monohydrate is best established for repeated high-intensity exercise and resistance-training adaptations. Without a loading phase, three to five grams per day generally raises muscle creatine stores over about three to four weeks. Loading at approximately 0.3 grams per kilogram per day for five to seven days only speeds the process and is optional.
Phosphocreatine helps regenerate ATP during brief, high-energy work. This can support more training volume and improve strength and lean-mass adaptations. Creatine does not replace resistance exercise.
Dan Bongino: I notice a large performance difference when I stop taking creatine, sometimes about two repetitions in a set.
Dr. Rhonda Patrick: I have noticed a similar personal change, but an individual's short-term experience is not a controlled result. Elevated muscle stores usually wash out over weeks.
Brain effects are promising but less certain. Small spectroscopy studies show that high-dose supplementation can modestly increase creatine in several brain regions. The classic German study used 20 grams per day in only six healthy adults. It did not compare five with 10 grams or show that muscle consumes all of a five-gram dose before creatine can reach the brain.
Evidence for cognition in healthy, rested adults is mixed. Some small trials and meta-analyses suggest benefits for memory in selected older adults or people with low dietary creatine, while a larger preregistered trial found no convincing benefit from five grams per day on its primary working-memory or reasoning outcomes.
Ten grams per day is not an established cognitive threshold or treatment for mild cognitive impairment. The idea that creatine works best in a “stressed brain” is a useful hypothesis, not a validated clinical rule.
The clearest stress model is severe laboratory sleep deprivation. In a randomized crossover study of 15 healthy young adults, one dose of 0.35 grams per kilogram—about 24.5 grams for a 70-kilogram person—partially improved selected cognitive tasks and brain-energy measures during 21 hours awake. A later 29-person study used 0.2 grams per kilogram and found benefits in several tasks, with reasoning the clearest result.
These studies did not show that creatine makes a person feel as though they slept eight hours. They did not reliably restore sleepiness or fatigue, replace the biological functions of sleep, or establish a daily high-dose rescue protocol.
A separate six-week trial in 21 naturally menstruating women found greater sleep duration after resistance-training days. The intervention contained five grams of creatine plus five grams of maltodextrin, not 10 grams of creatine. It did not improve chronic sleep or global sleep quality.
My own report of more mental endurance and less afternoon fatigue at 10 grams per day is an anecdote and may include a placebo effect. Intense learning has not been shown to create the same state as total sleep deprivation or neurodegeneration.
Conventional doses are generally well tolerated in healthy adults. Early water-weight gain and gastrointestinal symptoms can occur, especially with large single doses. Creatine can raise serum creatinine without reducing true kidney filtration, which can complicate creatinine-based kidney tests. People with kidney disease, pregnancy, relevant medicines, or unexplained abnormal kidney results should discuss use with a clinician.
High acute doses remain research protocols. Creatine should never be used to justify driving, operating equipment, or doing other safety-critical work while sleep deprived.
