Monkfruit doesn't come in a nice, familiar crystal form, and monkfruit extract is much sweeter per gram than sugar. For this reason, manufacturers bulk it up with some kind of sugar alcohol to make it easier to use. GP is saying they use erythritol for this purpose because the other options (e.g. xylitol) are toxic to pets.
