Robert F. Kennedy Jr. touts methylene blue for health and longevity

U.S. Health and Human Services Secretary Robert F. Kennedy Jr. sparked online interest after a video showed him taking methylene blue on a flight. The century‑old dye, approved for treating methemoglobinemia, is being promoted for off‑label uses such as boosting cellular energy, reducing oxidative stress, and supporting brain health. Preliminary studies suggest possible benefits for neurodegenerative conditions like Alzheimer’s and Parkinson’s, as well as for chronic fatigue and long‑COVID symptoms, though scientific evidence remains limited.

Kennedy’s advocates market a supplement called RECHARGE, combining methylene blue with urolithin A, claiming it enhances mitochondrial function, cognition, and overall cellular health. The product is positioned for anti‑aging and metabolic support, despite the lack of robust clinical validation.
