The Claim

In isolated mouse brain mitochondria inhibited by rotenone, methylene blue partially restores mitochondrial membrane potential, while its metabolite azure I does not, indicating that only methylene blue can bypass complex I of the electron transport chain under these in vitro conditions.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

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.

  1. Study: The Effect of Methylene Blue and Its Metabolite—Azure I—on Bioenergetic Parameters of Intact Mouse Brain Mitochondria

    Methylene blue can help mitochondria make energy even when a key part (complex I) is broken, but its cousin azure I can't do this. So only methylene blue works as a backup energy path in these brain cells.
