Wellness trends come and go, and today, one that’s making waves is methylene blue. This bright blue dye has a deep history—originating in the 1870s as a textile dye before being used as a treatment for malaria and cyanide poisoning. It’s even FDA-approved for treating methemoglobinemia, a rare blood condition.
Recently, however, online influencers have popularized it for supposed health benefits, positioning it as a “biohacking” tool for those wanting to enhance their well-being. Users claim it can boost energy, improve mood, and sharpen cognitive function. Some even suggest it helps with jet lag.
Lorne Hofseth from the University of South Carolina has researched methylene blue, explaining that it can aid cells in energy production. “It offers mitochondria a way to function better, especially under stress,” he notes. Animal studies show potential benefits, especially in reducing inflammation and protecting the brain. Yet, Hofseth urges caution, as benefits seen in the lab don’t always translate to humans.
While some small studies suggest methylene blue can lift mood or enhance cognition, results are tentative. Hofseth warns people not to rely on it as a supplement because the risks, like serotonin toxicity, can outweigh the potential rewards. He calls it “a waste of money” for most.
Nicole Brandt from the University of Maryland points out that cognitive experiences can feel very personal. Good days and bad days can sway how we feel about our mental sharpness.
The risks are significant. Methylene blue can have severe side effects, particularly for people taking certain antidepressants. It may also pose dangers for those with specific genetic disorders.
Furthermore, the supplement market is largely unregulated. Unlike drugs, supplements like methylene blue don’t require FDA approval before hitting the shelves. This lack of oversight raises concerns about product safety and authenticity.
Dr. Joshua Sharfstein from Johns Hopkins adds that buyers should be careful. “The internet is full of unregulated products,” he says.
In summary, if you’re considering methylene blue for health reasons, it’s crucial to consult a healthcare provider first. If you choose to proceed, be ready for the side effect of bright blue urine and teeth!
For those curious about getting the most from supplements, exploring reputable sources like Harvard Health can provide guidance on safe practices and reliable products.
