Classification: Other › Methylene Blue
Key Takeaway
Methylene blue has legitimate medical uses and a growing interest in mitochondrial and cognitive support. Quality grade (pharmaceutical vs industrial) is critical.
Why This Matters
Methylene blue was one of the first synthetic drugs and has a long history in medicine, including use against methemoglobinemia and malaria. More recently, it has been studied for its effects on mitochondrial electron transport, which may support energy production at low doses. In higher doses it can interact with serotonergic medications dangerously. Only pharmaceutical-grade methylene blue should be used for any internal application; industrial or aquarium-grade products contain contaminants and are not safe.
