How It Works
Methylene blue acts as an electron carrier, activating the enzyme NADPH-methemoglobin reductase. This process reduces methemoglobin — an abnormal form of hemoglobin that cannot carry oxygen — back to its functional form, restoring the blood’s oxygen-carrying capacity quickly and effectively.
