How Methylene Blue Works
Acts as alternative electron carrier in mitochondrial respiratory chain, improving energy production and reducing oxidative stress
Methylene Blue accepts electrons from NADH and transfers them directly to cytochrome c, bypassing damaged segments of the electron transport chain. This improves mitochondrial efficiency, reduces reactive oxygen species, and enhances ATP production. It also inhibits monoamine oxidase at low doses, contributing to mood and cognitive benefits.
Evidence Base
Preclinical Evidence
Extensive animal data showing neuroprotection, memory enhancement, and lifespan extension.
Human Evidence
Controlled trials confirm cognitive improvements at low doses with excellent safety profile.
Anecdotal Evidence
Users report sharper focus, improved memory, and elevated mood within hours of dosing.
