RFK Jr. Seen Adding Blue Liquid to Drink on Flight, Internet Speculates on Substance

The viral video of Robert F. Kennedy Jr., Health Secretary nominee, prompts speculation that the liquid may be methylene blue, a controversial compound with unproven health claims.

A video showing Robert F. Kennedy Jr. adding a mysterious blue liquid to his drink on a flight has gone viral, amassing millions of views on social media platforms like X and Reddit.
The leading theory among internet users suggests the liquid is methylene blue, a dye with medical uses but also touted in some circles for unverified health benefits such as cognitive enhancement and radiation protection.
Methylene blue is officially used to treat methemoglobinemia, a rare blood disorder, but its broader health claims remain scientifically unproven and require further research.
The video surfaced as RFK Jr., a controversial figure known for vaccine skepticism, awaits Senate confirmation for his nomination as Secretary of Health and Human Services by President Donald Trump.
The incident has sparked renewed scrutiny of RFK Jr.'s health-related views and practices, with critics questioning his reliance on alternative health methods over established science.
