What is Methylene Blue?

MetBlu was established with one goal: to provide high-purity, lab-grade methylene blue solution backed by transparency, trust, and consistent quality.

Our 1% USP-grade solution is made in the UK under strict quality control protocols, using purified water and pharmaceutical-grade methylene blue. We supply researchers, hobbyists, aquarists, and professionals who value reliable sourcing and clear labelling.

We understand the importance of knowing what’s in your bottle. That’s why:
We clearly state concentration and grade.
We supply batch-tested products only.
We package with care and dispatch promptly.
As a small, independent supplier, we also take pride in our responsive customer service. Whether you’re a researcher, home user, or institution, we’re here to help you get what you need — quickly and reliably.
