Caffeine in this category is a label question, not a marketing one: browse kombucha on Amazon and read the nutrition panel before you buy a case.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
