CJLS (Rabbi Isaac Klein) on gelatin
Gelatin is so thoroughly transformed from its source that it is no longer considered the forbidden substance. The CJLS accepts gelatin from any source as kosher and pareve.

How this shows up in a verdict
When the Conservative lens is selected and a product’s label touches gelatin, the verdict cites this record. The verdict reads “permitted” and names this ruling.
Other traditions on gelatin
Gelatin from a pig is from an unclean animal. Gelatin whose source is not stated is usually porcine or bovine, so we ask you to check the source rather than guess.
Leviticus 11:7-8 applied to derivatives
Gelatin of unstated source and other animal derivatives are marked for a closer look until the MJRC states a position. Porcine gelatin is treated as unclean.
