Creatine for the brain

Your brain uses creatine too So we built around it

Creatine supports the brain's cellular energy system. The creatine phosphocreatine system helps regenerate ATP during periods of increased energy demand.

Brain creatine is tightly regulated. Creatine enters the brain through regulated transport mechanisms, and brain creatine responds differently to supplementation than muscle creatine.

A broader formulation, not creatine alone. Micronised creatine plus ten supporting nutrients, selected around creatine metabolism, methylation and cellular energy.

Marius, founder of Brainstein

The founder

I built this for my mum. And my grandmother

My grandmother lost her memory in her sixties. My mum, earlier. At 38 I started feeling the same fog roll in, so I went looking for something that fights back, and when I could not find it, I built it. Two years on my own kitchen counter, tested on myself, every ingredient earning its place.

Peer reviewed

What research shows about creatine for the brain

16 RCTs. What the evidence suggests. A 2024 systematic review reported improvements in certain measures of memory, attention, and processing speed following creatine supplementation.¹ Research suggests context matters. Some studies report more noticeable effects under stress, fatigue, and sleep loss.

In one published study, brain creatine rose after several weeks of creatine supplementation, reaching up to approximately 8.7% in measured regions.² Published creatine studies helped shape Brainstein's multi week approach. Build first. Maintain after.

In a 2024 study, a high single dose of creatine improved certain cognitive measures during sleep deprivation, with effects observed for several hours.³ The study used a high experimental dose and investigated creatine, not Brainstein.

Research on this page describes creatine supplementation generally, not Brainstein. Unless stated otherwise, these studies did not test Brainstein as a finished product. Results varied across studies and cognitive domains.

Questions, answered

  • What is Brainstein?

    A brain creatine drink. 11 ingredients. 1 sachet. Zero stimulants. A daily formula built around creatine, cellular energy and cognitive support.

  • Why not just take regular creatine?

    Regular creatine provides creatine alone. Brainstein combines 10g of creatine monohydrate with 10 additional nutrients selected around creatine metabolism, methylation, cellular energy and cognitive support. It comes pre portioned into a daily sachet with no caffeine or stimulants. Same creatine molecule. A broader daily formula.

  • Who is this actually for?

    Anyone whose job is thinking. Students, knowledge workers, athletes, founders, parents. If your brain has to perform under load, you're the target.

  • When do I actually feel it?

    Brainstein is a daily protocol, not a stimulant style instant hit. Creatine supplementation is generally studied over repeated use, and individual responses vary. Consistency matters more than chasing a same day sensation.

  • Is creatine safe to take every day?

    Creatine monohydrate is one of the most extensively studied sports nutrition ingredients, evaluated across both short and longer term supplementation studies in healthy adults. As with any supplement, follow the label directions and speak with a healthcare professional if you are pregnant, nursing, taking medication, managing a medical condition, or have questions about whether Brainstein is right for you.

  • Can I stack this with other stuff?

    Brainstein already contains creatine, vitamins, minerals and other active ingredients, so check your total daily intake when combining supplements. Skip a second creatine product, you are already at a full dose. If you take medication or use several supplements, speak with a qualified healthcare professional before combining them.

  • When can I actually buy it?

    We're shipping to the founding cohort first. Public launch comes after. Join the waitlist and you'll be first to know when boxes start moving.

  • How much will it cost?

    Founder pricing is locked in for waitlist members. Forever. Public pricing lands later and it won't be this kind. Get on the list now.

  • Does it have caffeine?

    Zero. No caffeine. No stimulants. Built as a daily formula, not a buzz that fades by 3pm.

  • How do I take it?

    One sachet a day, mixed with water. That's it. No loading, no cycling, no complicated schedule.
