Shortly after its discovery in 1876 by Heinrich Caro, methylene blue made its way into the world of dyes. Originally developed for textile colouring, it quickly became known for its rich, deep blue luminosity. Cotton or wool fabrics could be dyed evenly and vibrantly with it. But this dye wasn’t limited to the fashion world: chemists, medical professionals, and microbiologists began using the deep blue compound to stain tissue samples, making cell structures more visible under the microscope. Even today, methylene blue is used wherever visibility is key – whether in test tubes, laboratory experiments, or creative projects. Thanks to its intense colouring power, just a few drops are enough to turn solutions into a vibrant blue.

Why is methylene blue not a dietary supplement?
