You probably heard of Vital Proteins.

They're the number one brand of collagen peptides in the U.S., and for good reason, a lot of people, myself included, take it pretty much daily to support things like healthy hair, skin, nails, bones, joints, all the good stuff. That starts to matter more the longer you've been walking around on this planet. But now, Vital Proteins is shaking things up. literally, you can tell a dad wrote this copy, with a brand new collagen and protein shake,

and this isn't your average protein shake that tastes like chalk and sadness. This one's light, chocolatey, super smooth, and it's got something pretty unique going for it, high quality protein, 30 grams of it plus collagen, that's pretty good ROI. Usually you're choosing one or the other, but Vital Proteins gives you both a ready-to-drink shake you can toss in your bag or fridge, zero added sugar, no artificial sweeteners, and no carogenin. And I don't know what that is, or if that's even how you say it, but you're supposed to avoid that. If you're already taking collagen or you're just curious about how it might support your hair, skin, nails, joints, and you don't want any carogenin, this is a super easy, tasty way to try it.

I'm your host, Jordan Harbinger.

Today I'm here with Skeptical Sunday co-host writer and researcher Jessica Wynn.

On the Jordan Harbinger show, we decode the stories, secrets, and skills of the world's most fascinating people

Our mission is to help you become a better informed, more critical thinker,

and during the week we have long-form conversations with a variety of amazing folks,

skeptical Sunday. A rotating guest co-host and I will break down a topic you may have never

thought about and debunk common misconceptions about that topic. Topics like acupuncture,

astrology, homeopathy, hypnosis, targeted advertising, fast fashion,

and more. If you're new to the show or you want to tell your friends about the show,
