gel·a·tin
noun \ˈje-lə-tən\
: a clear substance that is made by boiling animal bones or tissues and that is used in making jelly
: a food made with gelatin
Unfortunately many herbal supplements and medicines contain gelatin. With medicine, one may need to inquire with a doctor or the drug manufacturer. With herbal supplements, gelatin shows up in the small print under "other ingredients." Site's like www.SwansonVitamins.com clearly highlight many (but not all) of the supplements which are vegetarian, vegan, and organic which usually means GMO free and is always virtually GMO free.
