Unrelated but Metamucil is actually pretty awesome. I love spicy food but my stomach isn't so good at it, but if I take fiber beforehand I'm usually okay. Although since it's just fiber you can usually just get the store brand to do the same thing.
So, obviously research this yourself and don't listen to some dumbass on the Internet. As I understand it, there's a difference between soluble fiber and insoluble fiber. Soluble fiber is good for your cholesterol and blood sugar. Insoluble fiber is good for digestion. It's very likely that any fiber gummies are gonna be soluble fiber. I take the metamucil capsules for insoluble and fiber gummies for soluble.
Yeah, this whole ordeal really took the wind out of that and the RNC. The conspiratorial part of my brain says that this was planned weeks ago to do that.
