What is Methylene Blue?
Methylene blue is a blue compound that has been used in medicine and laboratories for well over a century. A prescription injectable form is approved for a specific blood condition and carries a boxed warning about serotonin syndrome when combined with certain medicines.
Why does it show up in memory and focus supplements?
It appears in some brain-support products because it is discussed in general wellness conversations. Evidence for supplement-sized amounts supporting memory or focus is limited, and the prescription form is not the same as a supplement.
What does the research say?
General background is available from the NIH Office of Dietary Supplements overview of supplements. Research on this ingredient in finished supplements is limited, and nothing here suggests it improves memory on its own or treats memory loss, dementia, depression or any other condition.

Safety considerations
Methylene blue can interact with SSRIs, SNRIs, tricyclic antidepressants, MAOIs and other medicines that affect serotonin, and it may be unsuitable for people with G6PD deficiency. It can also turn urine blue or green. It is not for anyone who is pregnant or nursing. Ask a healthcare professional first.
