Why Concentration and Grade Matter

Not all methylene blue sold online is the same. The two variables that matter most are concentration and grade — and both directly affect what you're actually getting.

Concentration: Our 2% solution (20 mg/mL) is the most practical concentration for measured oral use. At this percentage, 1 drop from a standard dropper equals approximately 1 mg — no scale required. Products sold at 0.1%, 1%, or unlabeled concentrations require either much larger volumes or much smaller, harder-to-measure drops. Some products on the market do not disclose concentration at all.

Grade: USP-grade means the raw material meets the purity specifications set out in the United States Pharmacopeia monograph for methylene blue. That monograph specifies assay limits, heavy metal maximums, and residual solvent controls. Our product is additionally third-party tested against these parameters before it ships.
