Glycerin is one of the trivial names for propane-1,2,3-triol. It's found in fats and oils, so it can be derived from any (dietary) fat or oil.It's a co-product (or biproduct) of making soaps and some biofuels, so while it can be made "from pigs" (specifically, from pig fat, or lard), certainly not all of it is. If you specifically want glycerin to be made from lard (or, more likely, want glycerin that is definitely not made from lard), you'd need to find a supplier willing to certify that no pig fat was used in the production.
