How does methylene blue work?
Methylene blue acts as an electron carrier in mitochondria in laboratory studies. It is a prescription medication, not a supplement. These laboratory effects have not been shown to improve energy, cognition or aging in people.
Methylene blue also inhibits monoamine oxidase A (MAO-A), the enzyme that breaks down serotonin. That is why it can cause serious or fatal serotonin syndrome when combined with SSRIs, SNRIs, MAOIs and some other medications. Side effects are possible, so your provider reviews your history and medications before prescribing and monitors you during treatment.
