Methylene Blue
Also known as: Methylthioninium Chloride · MB · ProvayBlue
A century-old pharmaceutical with remarkable mitochondrial-enhancing and neuroprotective properties, acting as an alternative electron carrier in the mitochondrial ETC.
Overview
Methylene Blue is one of the oldest synthetic drugs in medicine, first synthesized in 1876, with a remarkable range of therapeutic applications that are being rediscovered in the longevity and health optimization space. At low doses, methylene blue acts as an alternative electron carrier in the mitochondrial electron transport chain, accepting electrons from NADH and transferring them directly to cytochrome c, effectively bypassing Complex I and III blockades. This unique mechanism improves mitochondrial efficiency, increases ATP production, and reduces reactive oxygen species generation. Methylene blue has demonstrated neuroprotective effects in models of Alzheimer's, Parkinson's, and traumatic brain injury.
It also enhances memory consolidation, improves cognitive function, and has antimicrobial properties. Its ability to cross the blood-brain barrier and concentrate in neural tissue makes it particularly valuable for brain health optimization.
Mechanism of Action
Acts as an alternative electron carrier in the mitochondrial ETC, cycling between oxidized (MB+) and reduced (leucomethylene blue) forms. Accepts electrons from NADH and transfers them to cytochrome c, bypassing Complex I/III. At low doses, reduces ROS production and increases ATP synthesis. Also inhibits tau aggregation and monoamine oxidase A.

Known Interactions
The following interactions have been documented for Methylene Blue. Always consult a healthcare professional before combining compounds.
Use Caution (1)
Both affect dopaminergic and mitochondrial systems. Combined use may cause excessive dopamine modulation. 9-ME-BC also has MAO-inhibiting properties — use caution.
Synergistic (1)
Methylene blue acts as an alternative electron carrier in mitochondria while NAD+/NMN replenishes the primary coenzyme. Complementary mitochondrial support.
