Does it seem like the supplement section of your grocery store gets bigger every time you go in? Or that all television commercials these days seem to be advertising dietary supplements that promise to improve your concentration, help you lose weight, make you happier, healthier, smarter, stronger, cooler, poop better or some mix of those? You’re not imagining things. The explosion of the US dietary supplement industry over the past few years is very real, and when you’re inundated with ads for supplements everywhere you turn, it can be very difficult to navigate whether these things actually do what they say and how much they’re allowed to say without actually doing anything. That’s where this episode comes in. We take you through what supplements actually are, how their regulation in the US has changed over the past century, what dietary supplements can and cannot claim on their label, and how the supplement market has fared since the Covid pandemic (spoilers: it’s thriving).
