A journalist tested methylene blue, a supplement promoted for jet lag relief, on a long flight from New York to Sydney. While some, including Robert F. Kennedy Jr., reportedly use it, its efficacy for jet lag lacks clinical trials. The journalist experienced increased energy and better sleep but also side effects like taste loss and pins and needles. Methylene blue is FDA-approved only for a rare blood disorder. The journalist ultimately felt the benefits outweighed the side effects, but noted potential risks and the need for further research.
