Why methylene blue might help brain cells but its cousin azure I doesn't
The Effect of Methylene Blue and Its Metabolite—Azure I—on Bioenergetic Parameters of Intact Mouse Brain Mitochondria
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Surprising Findings
Azure I, despite being a more potent monoamine oxidase inhibitor and better tissue penetrator, cannot bypass complex I or restore mitochondrial membrane potential.
People assumed azure I, as a metabolite of methylene blue, would be at least as effective—if not better—at mitochondrial rescue, but it fails completely at this key function.
Practical Takeaways
If considering methylene blue supplements for brain health, be aware it may boost energy but also increase oxidative stress—consider pairing with antioxidants like NAC or vitamin C.

Methylene blue helps mitochondria, the energy factories in our cells, move electrons more smoothly so they don’t accidentally create harmful waste molecules called reactive oxygen species.
In a lab test with mouse brain cells, a chemical called methylene blue makes the energy-producing parts of the cells work harder without using energy to make ATP, while another chemical called azure I doesn’t do anything. This suggests methylene blue might be messing with how the cells normally control their energy production.
Scientists found that a blue dye called methylene blue can help fix a broken energy system in mouse brain cells, but a related chemical called azure I can't — meaning only the original dye can jump over a specific energy block.
A chemical called Azure I, which comes from methylene blue, doesn’t fix the energy power plants in mouse brain cells—even though it’s better at blocking certain brain enzymes. This means it might work in other ways, not by helping cells make energy.
In lab tests on mouse brain cells, methylene blue makes more hydrogen peroxide than azure I, but azure I is more efficient—it creates more of this chemical per bit of oxygen it uses. So even though it makes less overall, it’s more wasteful with oxygen.
