Read the originalThe Brain Creatine Bottleneck
Your brain runs on creatine Most supplements don't deliver it
Creatine is the brain's primary energy currency. It recycles ATP fast enough to keep neurons firing under demanding cognitive load.
But getting creatine into the brain is harder than getting it into muscle. The blood-brain barrier filters most of what you swallow, and brain creatine stores rebuild slowly. Standard creatine powders weren't built with this in mind.
Brainstein is engineered around that bottleneck. Micronised creatine for absorption, plus ten supporting cofactors that boost natural creatine synthesis, support delivery across the blood-brain barrier, and keep the energy system running.

What research shows about creatine for the brain
16 RCTs. One verdict. Creatine sharpens memory, attention, and processing speed.¹ The kicker: it hits hardest when your brain is on the ropes. Stress. Fatigue. Zero sleep. Exactly when winning matters most.
Brain creatine isn't a marketing word. Scientists watch it climb after weeks of dosing at clinical levels.² That climb is the whole reason IGNITE exists. Saturate first. Sustain after.
One dose. Nine hours of cognitive lift while sleep deprived, plus real shifts in brain energy chemistry.³ Fuel for the muscle that runs your entire life.

Questions, answered
-
What is Brainstein?
A brain creatine drink. 11 ingredients. 1 sachet. Zero stimulants. Built around how brain creatine actually accumulates: load hard for 4 weeks, sustain forever with one daily dose.
-
Why not just take regular creatine?
Regular creatine works for muscles. Most of it never reaches your brain. We added the cofactors that drag it across the blood brain barrier and the methyl donors that build more from the inside. Same molecule. Way more brain.
-
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?
Some people feel sharper within days. Real saturation takes 3 to 4 weeks. That's why loading exists. Load fast. Sustain forever.
-
Is creatine safe to take every day?
Creatine is one of the most studied supplements on the planet. Hundreds of trials. Decades of safety data. Yes.
-
Can I stack this with other stuff?
Yes. Brainstein plays nice with whey, multivitamins, omega 3, magnesium, and most stacks. Skip a second creatine product though. You're already at clinical dose.
-
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. No crash. Brain energy from the inside, not a buzz that fades by 3pm.
-
How do I take it?
Loading phase, weeks 1 to 4, two sachets a day. Maintenance, week 5 onwards, one sachet a day. That's the whole protocol.
