Methylene Blue

Evidence: ★★★☆☆ · Status: Prescription, OTC Supplement

💡 Did you know? Methylene blue began life as the first synthetic dye and became one of medicine's first synthetic drugs — at low doses it shuttles electrons for your mitochondria. (Yes, it turns your pee blue-green.)

In plain English

A blue dye that acts like a backup wire in your cellular power plants, keeping energy flowing, and gently raises mood chemicals. Low dose only — and it turns your pee green.

How it works

At low dose, an alternative electron carrier in the mitochondrial electron-transport chain (bypasses damaged complexes to sustain ATP) and a reversible MAO inhibitor; antioxidant at low dose, pro-oxidant high. FDA-approved (high dose) for methemoglobinemia.
