What is Methylene blue?
Methylene blue is a phenothiazine dye first made in 1876. It accepts and donates electrons, and at low concentrations it can feed electrons into the mitochondrial chain.
It’s an approved drug for methemoglobinemia.

Using Methylene blue in spray form
This is Methylene blue in a ready-made liquid, sold in a bottle with a metered spray pump. Each full press releases close to the same volume, so counting presses is a simple way to measure.
Prime the pump with a few presses before the first use, until you get a fine, even mist. Keep the nozzle clean and capped between uses, and note the number of sprays you use in your records.
Choosing a Methylene blue spray size
The spray comes in 30mL bottle (200mg) and 15mL bottle (100mg). Pick the size that matches how fast you’ll use it, since an opened bottle is best used within a few weeks.
Methylene blue quality and testing
Every batch of Methylene blue is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storing your Methylene blue
Keep it in a cool, dry place away from direct sunlight. Keep the bottle upright with the cap on, and wipe the nozzle after use. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
