Ultra Pure Liquid Methylene Blue

Liquid Blue (1.3%)

Methylene blue is a potent mitochondrial enhancer used to boost mental clarity, mood, and cellular energy. Just a few drops a day can supports optimal brain performance and resilience, helping you think sharper, feel brighter, and recover faster.

Blue Tung is one of Australia's leading and trusted sources for liquid MB since 2022. Ultra pure, USP grade and COA certified which means it's been tested for heavy metals and impurities.

How do I use it?

Dilute into a small amount (approx 50ml) of water or juice. * Pro-tip, citrus can help neutralize the bitterness. Avoid holding it in your mouth for long, unless you want to resemble the iconic blue-tongued skink (it's our logo for a reason!)

If you have dentures or veneers, use extra caution as it can cause permanent staining.

Please handle with care in general, it is a very potent pigment.

It can be consumed on an empty stomach.

Everyone has a different threshold, so we recommend starting with a trial dose (1 to 3 drops) to assess your individual response. Most people will take 10-15 drops comfortably, however some are very sensitive and will stick to 1-3 drops. Take the time to find your personal range.

Please note that all dosage information is a general guide only and not medical advice. We encourage you to do your own research and seek professional medical advice to make the best choice for your health.

PS: the higher the dose, you will notice a blue/green tinge to your urine after use. This is completely normal, and is in fact a benefit to your urinary tract system. MB has been used successfully in treating UTIs for decades.

Methylene Blue has the potential to interact with some medications and is not suitable for certain medical conditions. Please consult your healthcare provider if you're unsure before use.

Potentially serious interactions can occur when taken in conjunction with SSRIs (antidepressants), SNRIs, or MAOIs. Any medications that affect dopamine or serotonin, should not be taken with Methylene Blue.

Do not use if you are: pregnant, breastfeeding, have any type of renal impairment or have a G6PD deficiency.

Blue Tung products are not intended to treat medical conditions, are not evaluated by the TGA/FDA and are not for therapeutic use.

Can be stored at room temperature, but keep out of direct sunlight. Use within 24 months of opening. Keep out of reach from children, and be mindful when handling as it is a very potent pigment and stains very easily.

Brightness of mind

I’m an allied health professional in Australia. I’ve worked in mental health and physical therapy. I’m very aware of my mental state and physical health. I came across Blue Tung after looking into m-blue as a supplement. The best way to sum my experience is a brightness of mind and an increase in clarity of cognition. It sort of adds an extra layer of resilience to the mental load of my day. I didn’t have any m-blue for about a month and really noticed the difference. I love this brand, I love their product. Give it a go, there isn’t anything to lose, just don’t spill it!! Hope you enjoy and value this product as much as I do.

Better health, highly recommended biohack

I agree it is hard to find a good source of MB, so I'm glad we found you guys. Love the brand and love the product. Going slow first since we do eat a bit of food with tyramine in it, but since we are microdosing it shouldn't matter too much. Feeling good so far! I love the benefits this gives you, it's kind of wild that it's not more known about

Best Methylene Blue On The Market

OMG ... I've tried several Meth Blue but this one is the BOMB!!! I'm now on my third week taking the Blue - first two weeks I was feeling a bit off ... really tired, couldn't think straight, struggled putting sentences together - basically the worst brain fog I've ever had since menopause. Start of this week 15/09/2025 the Blue kicked in and put the pep back in my step and well and truly kicked in. Highly recommend ... my next purchase is going to be the Parasite Protocol if its as good as the Blue and I'm sure it is, I'm really looking forward to taking the protocol

Best I've used!

I've tried a number of Methylene Blue providers with varying results. No doubt the most consistently high performing product is that offered by Blue Tung.
A great product, fast delivery and good customer service.
Highly recommend!

Don't know what you've got 'til it's gone

I'm 50.
I knew Methylene Blue was making a difference for me. Cognitively. But I didn't realise how much of a difference until I ran out last week and hadn't ordered more.
I have gone a week now without having methylene blue and I can really feel the difference.
Lethargic. Not on point. Weary by mid afternoon. Back to how I used to be before I started taking methylene blue. The difference now, is I really notice the change methylene blue had made for me.
This stuff really works!

UTI's be gone

My mother has had chronic UTI’s for years, the only treatment being antibiotics, which caused their own problems. The longest time she had been asymptomatic is three weeks after a hospital admission. I started her on 3 drops of MB and reduced to 1 drop per day as a maintenance dose. It is 2 months now and no UTI. Her sinus infections (also chronic) cleared up as well. Thanks!

Experiencing Better Focus

I started taking BlueTung on 22 June, so it's been about four weeks now. I began with just 2 drops and gradually increased to 10 drops. While I haven’t noticed any dramatic changes, I have definitely experienced an improvement in my focus and find it easier to stay concentrated for longer periods. Looking forward to seeing how things progress with continued use.
