Remember when you could casually toss a tub of protein powder into your carry-on? Those days are over. 2026 rules limit powdered substances to 12 ounces (350ml) per container—unless you want a special pat-down that feels less like security and more like a very awkward hug. This includes everything from baby formula to your emergency stash of matcha.
And here’s a surprising fact: the TSA actually confiscates more protein powder than weapons now. Apparently, the gym bros are a bigger threat than the terrorists. If you must travel with powders, keep them in their original containers or risk having your pre-workout mistaken for cocaine. Yes, that happened to a guy in Denver, and yes, he had to explain to his boss why he was late.
