In recent months, the internet has been awash with a peculiar blue hue. TikTok users, podcasters, and even high-profile figures like Robert F. Kennedy Jr. have been seen dripping a vivid blue liquid—methylene blue—into their water, claiming cognitive enhancement, mood boosting, and even anti-aging effects. These dramatic ‘blue video’ moments have sparked curiosity and concern in equal measure. Yet, while the visual effect is captivating, experts warn that the claims surrounding this chemical are far from scientifically substantiated.
The Truth About the Blue Video Trend
The term “blue video” has become synonymous with viral clips showing individuals with azure tongues and water glasses tainted blue by a compound originally used in textile dyeing: methylene blue. This chemical was first synthesized in the late 1800s and was repurposed for scientific and medical uses, including malaria treatment and microscopic staining of bacteria. Its current trend on social media, however, highlights its use far beyond intended boundaries.
Methylene blue is, in fact, a recognized treatment for methemoglobinemia, a rare blood disorder where oxygen delivery is compromised. In hospitals, it plays a vital role in restoring the balance of hemoglobin. But its use as a supplement or cognitive enhancer is not only unsupported by robust research—it can be dangerous, especially when consumed unsupervised or in combination with antidepressants like SSRIs.
Understanding Methylene Blue’s Real Uses and Dangers
Medical professionals are unified in their stance: methylene blue is not a cure-all. According to Dr. Emily Austin of the Ontario Poison Centre, its proper use is limited to highly specific scenarios—primarily the treatment of methemoglobinemia, which can arise due to exposure to chemicals found in fertilizers or drugs like dapsone and amyl nitrites. Symptoms can include blue-tinted lips, confusion, and oxygen deprivation.
Yet, social media has blurred the lines between clinical treatment and casual usage. Influencers tout methylene blue as a mental clarity booster and even a cancer treatment, largely based on anecdotal evidence and early-stage animal studies. Dr. Joe Schwarcz from McGill University clarifies that while methylene blue and its derivatives showed early promise in Alzheimer’s-related tau protein research, the chemical taken orally has little impact on disease progression in humans. Moreover, combining it with SSRIs can trigger serotonin toxicity—an often-overlooked danger that can be life-threatening.

Why the ‘Blue Tongue’ Fad Needs a Reality Check
One of the biggest attractions of methylene blue on platforms like TikTok is its visual effect. Users proudly display their ‘blue tongue’ in videos, claiming instant clarity or improved energy. However, there’s a stark gap between appearance and efficacy. The claim that methylene blue can rejuvenate the mind, reduce oxidative stress, or reverse aging is not grounded in long-term, peer-reviewed scientific studies.
According to a 2023 systematic review of clinical trials, while methylene blue and its derivatives hold “potential” in reducing oxidative stress and neurodegeneration, the findings are preliminary. Issues with dosage, safety, and side effects remain. Furthermore, the commercially available version used in these blue videos lacks the modifications applied in medical research trials, weakening any comparison.
Combating Health Misinformation in the Digital Age
The blue video phenomenon is a textbook example of how compelling visuals and influencer culture can distort public perception. Joe Schwarcz remarks that a combination of scientific illiteracy and influential misinformation contributes significantly to such trends gaining traction. Many users fail to distinguish between a lab-based pilot study and clinically approved treatments.
It’s a reminder that viewers must scrutinize online health claims critically. Methylene blue is not approved by health authorities like Health Canada or the FDA for mood or cognitive enhancement. Health misinformation can not only waste money but endanger lives, particularly when it leads users to self-medicate without medical supervision.

What You Should Know Before Trying Viral Health Hacks
Before dipping into the latest social media health trend, users must do their research. Methylene blue has real medical applications, but its off-label usage can be harmful. It’s essential to consult healthcare professionals before experimenting with any chemical compounds touted as supplements. The blue video craze may be trendy, but it’s not a ticket to better health or cognition.
Ultimately, the blue video trend underscores a growing problem—viral misinformation overshadowing verified science. While methylene blue dazzles visually, its benefits do not match the online buzz. Users should proceed with caution and rely on expert medical advice rather than influencer-endorsed shortcuts.
FAQs about the Blue Video and Methylene Blue
Is methylene blue safe to consume?
When administered by a healthcare provider in controlled doses, methylene blue can treat specific medical conditions like methemoglobinemia. However, unsupervised use may lead to side effects including serotonin toxicity.
Can methylene blue improve memory or cognition?
There’s limited and inconclusive evidence supporting cognitive benefits from oral methylene blue. Early studies suggest some promise in altered forms, but further research is necessary.
Why are people posting blue tongue videos?
These videos showcase methylene blue’s striking visual effect, turning the tongue blue. Influencers use it to claim mood or brain benefits, though these effects aren’t supported by science.
Is methylene blue FDA approved for brain enhancement?
No. Methylene blue is not FDA approved for mood, brain function, or anti-aging purposes. Its medical use is strictly limited to certain conditions like methemoglobinemia.
Are there risks in combining methylene blue with other medications?
Yes. Combining it with SSRIs or similar medications may cause serotonin syndrome—a dangerous condition affecting heart rate, temperature, and muscle function.
What should I do before trying health supplements I see online?
Always consult a qualified healthcare provider. Even seemingly harmless supplements can interact dangerously with medications or underlying conditions.
