The blue all-round dye

Our methylene blue in a 1 % concentration in an aqueous solution is a dye with a deep blue colour. The solution consists of purified water and high-quality methylene blue with 99.8 % purity, free of heavy metals.

What is methylene blue?

Methylene blue (methylthioninium chloride) is a synthetic dye, a derivative of phenothiazine. It was first synthesized in 1876 by Heinrich Caro and patented as the first aniline dye. Paul Ehrlich did additional research on this substance. Methylene blue is manufactured particularly for use as a dye and for applications in various scientific disciplines.

We offer methylene blue to dye fibres, cotton, silk and paper.

Each bottle contains 100 ml methylene blue solution.

IMPORTANT: If medical attention is needed, keep the packaging/identification label. If feeling unwell after swallowing, call the poisons centre or consult a doctor. Not approved for internal use.

Positive effects in a short time
I rarely write reviews, but in this case it is very important to me :-). I have been taking the product for about 1.5 weeks at a dose of 10 drops (with orange juice) in the morning and evening. I can definitely say that I have seen the first positive effect. As I have a lot to do with deadlines in my job, my stress levels can be relatively high and I was very easily upset in the past few months. Now that I take Methylene Blue regularly, my mood has absolutely brightened. My high level of irritability has completely disappeared, I feel more clarity in my head again, which makes it easier for me to prioritise things. I am so excited to see what other effects I will see in the longer term :-).

Effective
I've been having a stroke for a year now, and over the last few months I've been suffering from asthenia, which is physically and mentally exhausting. I've been taking methylene blue since 16 September 2025. I started with 4 drops, then 5, then 10, then 15, then 20, for 4 days until today, when I gave my opinion. After 3 days, I felt a little less tired, then my energy took over again. My walk has become energetic again and I'm no longer brooding. My joy returned "what JOY and what happiness". After a month, I'll stop for 1 to 3 weeks and then resume the treatment. I will observe during the 3 weeks without taking and I will come back to share my second opinion.

Higher performance
I am over 60 and still exercise regularly. I started with 10 drops in the first week. Now I'm on 20 drops. Even in the first week I had the impression that my performance had increased and I was finding it easier.

Methylene blue
Hello, I was waiting to see the effects before leaving a review. I'm very satisfied, it has been very effective on my weak point, my lungs. It has enabled me to clean up my lungs, to get rid of a persistent cough and stuck lung secretions and to feel much better oxygenated, my mitochondria tell me. Thank you!

The benefits of methylene blue
Thank you for everything, your site is great and so are your products. The reception of the products was perfect, everything was well packed. For information, I advise future buyers of methylene blue to read the book by Dr. Laurent Schwartz, to fully understand its use and all the virtues of the product.
