Is your Methylene Blue safe?
Our Methylene Blue is USP (Pharmaceutical) Grade. Every batch is tested by an independent laboratory; the current Bilacon report covers heavy metals and microbiology and describes the results as unremarkable. You can see the full report on our lab results page. No fillers are added.
We place a lot of importance on the purity of our products and the quality of our ingredients, and use the highest quality suppliers and manufacturers in Europe.
Before you buy however, please do refer to our health disclaimer.

Is Methylene Blue FDA-approved?
Methylene blue is FDA-approved in one specific form: a prescription injection (ProvayBlue®) used in hospitals to treat acquired methaemoglobinaemia. VitaBlue products are not that medicine, are not FDA-approved and are sold for research use only. Methylene blue itself has been the subject of more than 18,000 published studies.
Do you have a risk-free guarantee?
If you do not feel our products helped or are unhappy in any way, please Contact Us, and we will make it right. That's a promise.
How much Methylene Blue should I start with?
Studies show doses between 5 mg - 15 mg are effective and 90% of people report 5 mg to be their go-to dose, however we would recommend to start with a much smaller dose of 1mg.
Please start small, and consult our blog post on proper dosages and administration, as well as our Health Disclaimer.
Does Methylene Blue break a fast?
Methylene blue itself contains no calories. Research in cells and animals suggests it may interact with fasting-related processes such as mitophagy; this has not been established in people. We covered the research on our blog post.
Will Methylene Blue make my pee green and my tongue blue?
Yes! This is normal (and temporary!). It will vary from day to day depending on the dose, hydration levels, micronutrients in your food intake and how you administer it. Methylene Blue is a very strong blue dye and should be treated carefully, we covered everything on safe handling, doses, administration and even taste in our blog post.
Will Methylene Blue make my brain blue?
No, if you've heard this thrown around, it's nothing but fear-mongering. This has only happened with extremely high dosages in very specific circumstances (i.e MB was used to try revive people in a state of septic shock, in a very high IV dose, and it wasn't metabolised properly as organs weren't functioning. PMID: 32940886). See here an explanation from Dr. Scott on the issue.
