@CassieK Well, techically is in the sugar family but, again, it isn't going to be a huge issue. They use it much more in candy to make it shiny and it would be a bigger problem there!! More important, always that you take the meds you need.
Hmmm, I wouldn't think there would be a problem with glycerin on W30 as it is a non-digestible ingredient. It literally goes right through you. It's purpose in supplements is to hold onto the active ingredients and slow release them as they travel through your system so you get maximum benefit from them. Most absorption of nutrients takes place in the intestines so the nuttrients themselves have to get through the firebath of acid that is our stomachs first. Glycerin helps them do that.
And @CassieK if what is doing is helping you retain your hair so that you have enough left over to pull out running after 4 kids then you better take it!!
