What Is Methylene Blue and Why Is It Gaining Attention for Health?
Methylene blue (MB) is a bright blue liquid that has been used in medicine since the 1980s. While it may look unusual, it has caught the attention of scientists, doctors, and even biohackers for its unique properties. But what exactly is methylene blue, and is it something you should consider for your health and wellbeing?
Let’s explore what it is, how it works, and why some people are talking about it — backed by science and explained in simple terms.
Important Note: Methylene blue is not a cure or treatment for any illness unless prescribed by a doctor. This article is for informational purposes only and does not substitute professional medical advice.
1. What Is Methylene Blue?
Methylene blue was first created in 1876 as a fabric dye (Berneth, 2008). But scientists like Robert Koch and Paul Ehrlich quickly realised it had powerful medical potential. It was one of the first dyes used in microscopes to stain bacteria, which helped doctors better study infections (Ehrlich, 1881; Oz et al., 2011).
Soon after, methylene blue was used to treat malaria — making it one of the first synthetic medicines ever used in humans (Guttmann & Ehrlich, 1891). Before antibiotics like penicillin, methylene blue was commonly used as an antiseptic in medical care (Oz et al., 2011).
Today, researchers are exploring other uses for methylene blue in the brain, cells, and even energy production. It is often sold in purified forms — like the USP-grade methylene blue solution — which is safe for human use when taken appropriately and with guidance.
2. Why Is Methylene Blue Making a Comeback?
Methylene blue has gone viral—and not just for its vibrant blue hue. Its recent surge in popularity ramped up when Robert F. Kennedy Jr. was seen mid-flight adding a bright-blue liquid to his drink. That moment exploded online, igniting a wave of conversations. Soon, Google searches for “methylene blue” skyrocketed, and TikTok influencers began touting its benefits for brain support, focus, and healthy aging.
But the biggest spike came after The Joe Rogan Experience featured episodes with Mel Gibson and Chase Hughes - revealing that they personally, or others close to them, experienced profound health benefits from Methylene Blue. Following those episodes, searches for medical-grade methylene blue exploded—Blootropic emerged as the go-to Australian brand.
3. How Does Methylene Blue Work in the Body?
Your body’s cells create energy in little structures called mitochondria. Think of mitochondria like tiny power plants inside your cells. Methylene blue helps these power plants work better.
It does this by:
- Helping your cells use oxygen more efficiently
- Reducing stress from harmful molecules called “free radicals”
- Supporting cell repair and energy production
This is why researchers believe methylene blue may
- Help mitochondria work more efficiently
- Support energy production (ATP)
- Protect cells from stress caused by oxidation
- Cross the blood–brain barrier to support brain cells
These effects are still being studied, but researchers believe this may be why some people report better focus and energy after using it.
4. Medical Uses of Methylene Blue
Methylene blue is approved for treating:
- Methemoglobinemia (a condition where blood can't carry oxygen properly)
- Cyanide poisoning (in emergency care)
- Used during some surgeries to help doctors see tissues better
It is also being studied for:
- Alzheimer’s disease
- Parkinson’s disease
- Infections and inflammation
Note: These studies are early-stage, and methylene blue should not be used to treat these conditions without medical advice.
5. Why Biohackers and Wellness Seekers Use Methylene Blue
In the biohacking world, people are always looking for ways to boost their brain and body performance. Methylene blue has gained popularity because of its potential to:
- Improve focus and memory
- Reduce brain fog
- Increase energy
Some users combine it with light therapy or other nootropic supplements. However, these uses are not officially approved by health authorities. Always speak with a health professional before trying it.
6. What Do Studies Say About Methylene Blue?
Research shows that methylene blue can:
- Help cells make more energy (ATP)
- Cross the blood–brain barrier (meaning it can enter brain tissue)
- Act as a strong antioxidant, protecting brain and nerve cells
A 2021 review published in the Journal of Neural Transmission highlighted that low doses may support brain function. However, the Therapeutic Goods Administration (TGA) has not yet reviewed methylene blue for cognitive enhancement or mental health in Australia.
7. Forms of Methylene Blue: What Should You Use?
Not all methylene blue products are the same. Some are made for industrial use and are Not all methylene blue products are created equal. Some are made for industrial purposes, while others—like certain aquatic versions—are intended for fish tank treatments. These types are not safe for human consumption.

Only purchase USP-grade or pharmaceutical-grade methylene blue that is labelled for human use. Industrial or lab-grade versions may contain harmful impurities like:
- Heavy metals
- Solvents
- Dyes not meant for human consumption

B. It Can Interact With Medicines and Supplements
Methylene blue affects the way your brain and body use chemicals like serotonin, which means it can be dangerous when combined with certain medications.
Do not use methylene blue if you are taking:
- SSRI antidepressants (like sertraline/Zoloft, fluoxetine/Prozac, escitalopram/Lexapro)
- MAO inhibitors (like phenelzine or tranylcypromine)
- Stimulants (like methylphenidate/Ritalin or dextroamphetamine)
- Parkinson’s medications (like selegiline)
- Antipsychotics
- Opioid pain medications combined with antidepressants (e.g. tramadol + SSRIs)
Mixing methylene blue with these can lead to a serious condition called serotonin syndrome, which can be life-threatening if not treated.
C. Caution With Supplements
If you're already taking other supplements that affect brain chemistry or blood pressure, be cautious. Examples include:
- St. John’s Wort
- 5-HTP
- L-tryptophan
- Ginkgo biloba
- High-dose B vitamins
These may interact or amplify effects in unpredictable ways.
D. Speak to a Health Professional First
Because methylene blue can affect your brain and cell function, it’s important to:
- Get advice from a GP or health practitioner
- Mention all the medicines and supplements you're taking
- Start with a trial dose and track how your body reacts
E. Not Suitable for Certain Groups
Avoid methylene blue if you:
- Are pregnant or breastfeeding
- Have kidney or liver conditions
- Are under 18 without medical guidance
- Have G6PD deficiency, a rare enzyme disorder that can cause serious side effects when exposed to certain drugs, including methylene blue
F. Choosing the Right Product
