5,000 drops of pharmaceutical-grade purity — crafted in small batches in Byron Bay.
Our 250ml Methylene Blue is our most popular size for good reason. It's the choice of people who've tried MB, loved it, and want a larger supply without constantly reordering.
Every bottle is made in small batches using pharmaceutical-grade base material, independently tested by the Environmental Analysis Laboratory (EAL) at Charles Sturt University for purity and concentration, and bottled in UV-protective glass to preserve the integrity of the solution.
No fillers. No additives. Just pure 1% Methylene Blue in purified water — exactly what it says on the label.
We have the certificate of analysis on hand at your request — because quality should be something you can verify, not just something we claim.
WHY THE 250ML?
- 5,000 precisely measured drops per bottle
- Best cost-per-drop of all our sizes
- Less frequent reordering than our smaller bottles
- UV-protective cobalt glass bottle preserves the solution
- Includes our guidance card with every order

FREQUENTLY ASKED QUESTIONS
What is pharmaceutical-grade Methylene Blue?
Pharmaceutical-grade Methylene Blue is manufactured to a high purity standard appropriate for human-facing products, distinct from industrial or reagent grades sometimes sold for aquarium or laboratory use, which aren't manufactured to the same standard and can contain contaminants. Our 250ml is pharmaceutical-grade and independently verified by the EAL at Charles Sturt University.
How do I know this Methylene Blue is pure?
Every batch is independently tested by the Environmental Analysis Laboratory (EAL) at Charles Sturt University, an accredited Australian analytical laboratory. We hold a Certificate of Analysis for every batch we sell, confirming purity and concentration — and we publish it, because quality should be something you can verify.
Is this safe?
We can tell you about our product's quality — pharmaceutical-grade Methylene Blue, independently tested by the EAL at Charles Sturt University for purity and concentration. What we can't do is tell you whether it's right for you. Methylene Blue can interact with certain medications, particularly some antidepressants, and isn't suitable for everyone. Please speak with a qualified healthcare professional before use, especially if you have any health conditions or take medication.
How do I use it?
Each bottle includes a dropper for easy handling. Methylene Blue is typically diluted in a glass of water before use — we recommend adding your drops to water rather than taking it directly, both for taste and to reduce staining. A guidance card is included with every order with clear handling instructions. Beyond that, we always recommend speaking with a healthcare professional about what's right for you.
Will it stain my skin or teeth?
Methylene Blue is a strong pigment and can temporarily stain. Diluting it in water before use reduces this significantly. If you have a spill, our Blue Rescue spray is specifically designed to remove MB stains from skin, surfaces and fabrics.
Why is it blue?
That's exactly what you want to see. The blue colour is the compound itself — it means your solution is pure and correctly concentrated.
How long will the 250ml last?
That depends entirely on how you use it, and everyone's approach is different. The 250ml is our best-value size per drop, designed for anyone who's already decided MB is right for them and wants to reorder less often.
Do you ship internationally?
Yes. We ship regularly to New Zealand, and we're happy to send to other countries where we can.
If your country is available at checkout, you can order as usual — delivery options and costs are shown before you pay. If it isn't listed, get in touch and we'll let you know what's possible for your location.
Import rules for products like ours vary from country to country. Please check that you're able to receive it where you live before ordering. Any customs duties or local taxes are the responsibility of the buyer.
What if I spill it?
Don't panic — grab our Blue Rescue spray, which is specifically formulated to remove Methylene Blue stains from skin, surfaces and fabrics.
