I just contacted Nature's Sunshine about their gelatin capsules. There is definitely NO MSG in their capsules. Nature's Sunshine capsules are made solely from bovine gelatin.

With my sensitivity to MSG, I would certainly be able to tell if there was any in the NSP gelatin capsules, because I take a lot of encapsulated supplements. As such, I've never had any reactions whatsoever.

I believe the type of "gelatin" referred to in the earlier list is "jell-o" type gelatin. However, it would be a good idea for you to check with your company and make sure they don't use any "additives" in the vegetarian capsules to make them stronger. I, too, have heard that vegetarian capsules are more brittle, so it might be good to find out what is used to create them.
