Brominated vegetable oil (BVO) is a food additive used to keep flavoring oils well-blended in beverages, especially citrus-flavored ones. BVO is a controversial ingredient because it contains bromine, which can cause health issues when consumed in large quantities. The FDA has proposed a ban on BVO, and California has already banned it. Many large beverage brands, including Coca-Cola and Pepsi, have stopped using BVO, but it can still be found in some smaller grocery store brands and regional beverages. Here is a list of some sodas that contain BVO:

• Sun Drop citrus soda
• Some Food Lion-brand sodas
• Some Great Value-brand sodas
• Mountain Dew Throwback (original formula)
• Squirt
• Fresca Original Citrus
• Powerade in Fruit Punch and Strawberry Lemonade flavors
• Some generic citrus sodas, including "Mountain Lightning"/Walmart sodas, "Clover Valley"/Dollar General sodas, "Orangette," and Stars & Stripes

However, many beverage makers have reformulated their products to replace BVO with an alternative ingredient.
