The guy next to me seems enamored with his effervesce. He’s dropping some high-dose vitamin C powder into a cup of water he requested from the flight attendant, and looks to be enjoying it like it was a rare, 25-year-old Scotch.
“I take this every flight,” he says to the no people who asked him. “That’s my secret. Hundred-thousand miles a year and I never get sick. I swear by this stuff.”
I asked him what he did for a living, and he was not, in fact, a dietitian or a medical professional. He was just a guy in a field that required a lot of travel, which got me wondering: Was there anything in that little fizzy cup that was proven to work better? Or are vitamin C supplements a whole lot of anecdotal evidence and placebo with a nice marketing package attached?
