What Is It?
A 150-year-old medicine. Synthesized in 1876 as a textile dye. Repurposed for malaria in 1891 — making it the first fully synthetic drug in human medicine. FDA-approved for methemoglobinemia. On the WHO Essential Medicines List.
How Does It Work?
Your mitochondria are an assembly line — passing electrons down four stations to make energy. When a station breaks, the line stops. Methylene blue is the understudy that knows every part. It picks up electrons from the broken stations and delivers them past the gap. An alternative electron carrier that bypasses Complex I/III damage in the mitochondrial electron transport chain. Crosses the blood-brain barrier.
Primary Benefits (research suggests)
- Cellular oxygen consumption up to 70% increase
- ATP up approximately 30%
- Inverted U-shaped dose curve — low doses help, high doses hurt
