Expert Answer
Does creatine help with brain function?
Quick Answer
Yes - and dose matters. Experts agree on 5g/day of creatine monohydrate for cognitive benefits; Attia and Patrick suggest 10g, up to 10-20g during acute high-stress periods or sleep deprivation. The brain uses 20% of the body's energy, and creatine helps recycle ATP for cognitive processing. Huberman covers high-dose (0.4g/kg) creatine for TBI recovery.

“creatine supplementation of five grams per day, that's creatine monohydrate, has been shown to improve cognition”

Lists creatine among his 6 essential supplements specifically for cognitive function as we age.
Detailed Answer
Creatine's cognitive benefits are one of the strongest areas of expert agreement. The brain consumes 20% of the body's energy, and supplemental creatine helps recycle ATP more efficiently - especially during sleep deprivation, stress, and aging.
Attia and Patrick explored this in a dedicated discussion, suggesting 10-20g during high-stress periods for enhanced cognitive benefits. At standard doses (5g/day), Attia calls creatine monohydrate the "gold standard" for both strength and cognitive benefits.
Huberman recommends 5g daily across 19 videos for cognitive function and covers high-dose creatine (0.4g/kg body weight) for reducing headache frequency, dizziness, and fatigue following traumatic brain injury.
Hyman lists creatine among his six essential supplements specifically for cognitive function as we age, alongside a multivitamin, omega-3s, polyphenols, vitamin D, and magnesium.
Vegans and vegetarians may benefit most from creatine supplementation for brain health due to lower dietary intake from the absence of meat (Patrick, Candow).
Related Questions
How much creatine should I take for brain benefits?
5g/day of monohydrate is the baseline all five experts agree on. Attia and Patrick suggest 10g - up to 10-20g during acute high-stress periods or sleep deprivation - for enhanced cognitive benefit.
How long does creatine take to work for brain benefits?
Muscle saturation takes about 4 weeks at 5g/day. Brain benefits may take a similar timeframe. Higher doses (10g+) may produce cognitive effects more quickly.
