Creatine Monohydrate for Brain Health
Creatine Monohydrate: the brain fuel everyone forgot
Pure pharmaceutical-grade creatine monohydrate from a global research-grade manufacturer. No flavoring, no fillers, no proprietary blend. The version that has 700+ controlled trials behind it, including the cognitive ones.
Why Action Potential Supplements exists
The brain uses roughly 20% of the body's energy. When you ask it to think hard, learn quickly, or stay sharp through a fatigue load, that energy demand spikes. Most of the people I worked with had no idea their cognitive symptoms were a fuel-supply problem.
I'm Dr. Sean Orr. I trained as a neurologist, and for years I watched the same pattern repeat in clinic. High-functioning adults arriving with brain fog, slowed mental processing, mid-afternoon collapse, and the sense that their thinking wasn't as sharp as it used to be. Their imaging was clean. Their labs were "normal." Pharmaceutical options were thin. The deficit, in many cases, was metabolic. Their neurons weren't producing ATP fast enough to keep up with what they were demanding of themselves.
Action Potential Supplements was built around that clinical observation. When you give the nervous system the raw materials it needs to run cleanly, the neuronutrients, the brain often follows. Creatine is one of the cleanest examples in the entire supplement category, and it has been criminally under-prescribed for cognitive support for the last 30 years because the cultural label on the jar said "gym bro."
Every product in our catalog starts from that premise. We are not selling commodity supplements. We are selling the inputs we wished the people we worked with had been getting all along.
The case for creatine, made for the brain
Creatine is a small molecule the body makes in tiny quantities in the liver and kidneys, then ships out to tissues with high energy demand. The classic textbook tissue is skeletal muscle. The less-appreciated tissue is the brain. Neurons run on ATP. ATP comes from glucose oxidation and from the phosphocreatine shuttle. When the shuttle is well-stocked, neurons can sustain firing rates that they otherwise can't.
The catch is that endogenous synthesis plus a typical Western diet does not get most adults to the saturation level used in the cognitive literature. The classic loading protocol of 20 g/day for 5 days, then 3-5 g/day maintenance, is what nearly every controlled trial uses. Hitting that from food alone requires about a pound of red meat per day, which neither I nor any reasonable person is going to do.
What this product is, mechanically: 250 grams of pure creatine monohydrate from a manufacturer whose material is used in the published studies. No flavoring, no proprietary fairy dust, no questionable filler. One ingredient, dosed at the level the trials actually used.
What the research actually says
Creatine for cognitive performance under sleep deprivation
A 2024 randomized crossover trial in Scientific Reports gave 15 healthy adults a single 0.35 g/kg dose of creatine monohydrate before a night of total sleep deprivation. Cognitive performance and reaction time were measurably preserved versus placebo, with effects detectable as early as 90 minutes post-dose. The mechanistic interpretation is that creatine buffers the ATP drop that sleep deprivation imposes on the cortex.

Creatine and memory in older adults
A 2023 systematic review and meta-analysis in Nutrition Reviews pooled 16 randomized trials covering creatine supplementation and cognitive outcomes. The signal was strongest for memory tasks in older adults, particularly for measures of short-term memory and reasoning. The authors specifically called out 5 g/day for at least 4 weeks as the minimum effective protocol.

Why vegetarians may notice the most
Dietary creatine comes almost exclusively from animal flesh. Vegetarians have measurably lower intramuscular and intracerebral creatine stores than omnivores. A landmark 2003 study in the Proceedings of the Royal Society B showed vegetarians given creatine for 6 weeks showed larger gains on working memory and intelligence testing than omnivore controls receiving the same dose. The interpretation is straightforward: they were starting further from saturation.

Safety and the kidney question
Creatine is one of the most-studied supplements in existence. A 2021 position paper from the International Society of Sports Nutrition reviewed 50+ years of safety data and concluded creatine monohydrate at recommended doses is safe in healthy individuals, including older adults, with no evidence of kidney damage. The myth about kidney harm traces to a single elevated creatinine measurement, which is a downstream metabolite of creatine and not a marker of renal injury in this context. If you have existing kidney disease, talk to your nephrologist before starting.

Stack it for the full cognitive package
Creatine handles the energy substrate. For the neurotransmitter and signaling layer, our Brain Focus Nootropic Formula adds DMAE, L-Tyrosine, Bacopa monnieri, and phosphatidylserine. Many customers running both report a noticeable difference in afternoon stamina and the ability to hold complex thinking later in the day.
Brain Focus Nootropic Formula
DMAE + Bacopa + L-Tyrosine + phosphatidylserine. The signaling layer that sits on top of creatine's energy layer. $29.81 · 60 caps.

Do I have to do a loading phase?
No. Loading (20 g/day for 5 days) gets you to saturation faster, in about a week. Skipping the load and taking 5 g/day still gets you to the same place, just slower, in roughly 3-4 weeks. The cognitive trials use both protocols. If you're prone to GI sensitivity, skip the load.
Will it make me gain weight?
Creatine pulls water into muscle cells. Some people see 1-3 pounds of scale weight gain in the first 2 weeks. That is intramuscular water, not fat. If you're tracking the scale closely, expect the bump and don't read it as fat gain.
Can I mix it with anything?
Yes. Water is fine. Juice is fine. Coffee is fine despite the persistent internet folklore about caffeine interfering with creatine (the original 1996 study has been challenged repeatedly and most newer work shows no meaningful interaction). The only thing I'd avoid is hot liquids over time, which can degrade creatine to creatinine.
Subscribe and save?
Yes. Subscription drops the per-tub cost and ships every 30 days. Pause, change cadence, or cancel from your account at any time. Most customers running the maintenance protocol prefer it because creatine works best when taken daily, and the subscription removes the "did I run out?" failure mode.
