Cognitive EnhancementMethylene Blue: Cognitive Enhancement & Mitochondria
Methylene blue is an old dye and medication gaining biohacking attention as a mitochondrial enhancer and nootropic at micro-doses (0.5–4mg). It accepts electrons in the electron transport chain, potentially improving ATP production and brain oxygen utilization. The hype exceeds the evidence — but the mechanism is real and human safety data exists at low doses.
