Nerds is not a vegan candy product if you are a strict vegan. Some flavors use an ingredient called carmine to give them their bright colors, which comes from insects. However, some flavors of Nerds are vegan including grape, which is not made with carmine. Read the product ingredients very carefully if you are on a strict vegan diet or you are concerned about which flavors of Nerds are truly vegan and which ones are not.
