About This Episode

This week, Emily and Perry examine methylene blue—the synthetic dye beloved by wellness influencers that promises to energize your mitochondria, boost your mood, and improve your memory. They dig into the biology of the electron transport chain, the history of methylene blue’s real medical uses, and the surprisingly interesting MAO-inhibitor angle.

Plus: Driscoll’s strawberries and pesticide panic, an Ebola outbreak in the DRC, and the FDA’s tanning bed reversal. And in the mailbag: does cracking your knuckles really cause arthritis?
