Methylene Blue

Methylene blue may improve energy production when there is a genuine electron transport block. The recommended dosage of methylene blue is 10 drops for children and 20 drops for adults in water, consumed with a straw to avoid staining teeth. Feeling better after methylene blue does not necessarily prove mitochondrial improvement because MAO-A inhibition can produce antidepressant-like effects. Methylene blue can interact with SSRIs or other serotonergic agents and contribute to serotonin toxicity. Methylene blue is described as having three primary mechanisms: hydrogen peroxide generation, MAO-A inhibition, and mitochondrial respiratory-chain rerouting. Methylene blue reduces oxidative stress specifically within mitochondria. Methylene blue's mechanism is distinct from dietary antioxidants — it works within the mitochondrial electron transport chain to reduce electron leakage and free radical generation. Methylene blue may reduce efficiency when the respiratory chain is already functioning well. Hydrogen peroxide generation from methylene blue is described as dose-sensitive and potentially concerning at antidepressant-level doses.
