<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone know the truth about glycerin? I have read so many conflicting things. Some say it contains MSG and Celiacs should not have MSG (right?). I've been trying to be GF since my diagnosis a year and a half ago and I keep finding out different things that I really shouldn't be eating. I am supposed to be taking supplements right now, but they are glycerin gel caps. Help! Debbie/Arizona
