Hank Green in 2018 joked that everyone should take Metamucil, the fiber-rich powder that is supposed to help with your BMs. But is he right? Well . . . “should” is a strong word. Dr. Sydnee goes through the history of the supplement itself, made of psyllium, as well as our understanding of fiber and its use in human nutrition. And yeah, you probably aren’t getting enough of it.
