The Claim

In isolated mouse brain mitochondria, methylene blue increases hydrogen peroxide production more than azure I (290% vs. 230%), but when normalized to oxygen consumption, azure I produces a higher proportion of H₂O₂ per oxygen molecule used, indicating differential efficiency in reactive oxygen species generation between the two compounds.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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

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.

See the scientific wording

In isolated mouse brain mitochondria, methylene blue increases hydrogen peroxide production more than azure I (290% vs. 230%), but when normalized to oxygen consumption, azure I produces a higher proportion of H₂O₂ per oxygen molecule used, suggesting differential efficiency in ROS generation.

What the research says

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

    Both dyes make brain mitochondria produce more hydrogen peroxide, but azure I does it without helping the mitochondria breathe better—so it’s less efficient and makes more harmful molecules per bit of oxygen used.
