We didn’t guess. We proved it.
Numin is built on a specific neuroscientific mechanism and validated in a peer-reviewed clinical trial. This page is everything we know, everything we tested, and everything we found.
Why your thinking degrades by mid-afternoon.
Every decision you make — from morning emails to afternoon meetings — produces glutamate in your lateral prefrontal cortex.
As glutamate accumulates, neural signalling becomes less efficient. The result: slower thinking, weaker focus, and worse decisions — not because you’re lazy, but because your brain chemistry has shifted.
Double-blind. Placebo-controlled. Crossover. Published.
Design:
Randomised, placebo-controlled, crossover
Participants:
Healthy adults under sustained cognitive load (13-hour protocol, 10 competitive matches)
Duration:
Two 13-hour sessions with 7-day washout between arms
Published:
Frontiers in Nutrition, 2025
Conducted:
Phoenix, AZ
"While the placebo group showed a statistically significant decline in cognitive efficiency after 4 hours, the Numin group maintained baseline performance until the end of the observation window."
43% fewer decision errors
Under sustained cognitive load compared to placebo.
Performance held stable
Across a 13-hour session. Numin users maintained tactical execution from morning to evening.
Improved strategic communication
Strategic communication measured in real-time during competitive play.
Five ingredients. Each one does a specific job.
Standardised to 3% rosavins and 2% salidrosides. Rosavins support stress resilience; salidrosides protect against excitotoxic neural injury. Research in human cortical neurons shows significant protection against glutamate-induced cell death.
Ten times the potency of standard turmeric, engineered for bioavailability. Supports mood stability and reduces neural inflammation under load.
Neurotransmitter support. Supports working memory and cognitive flexibility when reserves deplete under stress.
Crosses the blood-brain barrier. Suppresses oxidative stress to preserve the signalling environment your decisions depend on.
Supports glucose uptake to the prefrontal cortex so your brain maintains its preferred fuel source during sustained work.
Made in the USA.
