Methylene blue use

Methylene blue has gained attention for its potential health benefits, particularly its effects on cognitive function and mitochondrial activity. Historically, methylene blue was the first pharmaceutical ever prescribed in the United States, commonly used to treat carbon monoxide poisoning by helping red blood cells displace carbon monoxide with oxygen, effectively acting as an oxygenator 1.

In recent years, methylene blue has been explored for its cognitive-enhancing properties. It is thought to improve brain function by enhancing mitochondrial performance and has been linked with cognitive stimulation. A commonly recommended dosage is around 10 mg taken in the morning, often combined with other agents like caffeine and B vitamins to boost brain function. However, methylene blue is known to cause the urine to turn green or blue 2.

It's important to be aware that while methylene blue is available as a prescription drug, it can also be found as an over-the-counter supplement. There are cautions around its use, especially in high doses or when introduced intravenously, as it can cause vein spasms and other discomforts 3. As with any supplement, it's advisable to consult with a healthcare provider before starting its use to ensure safety and appropriate dosage.
