While technically not a juice, sports drinks are often situated near juice products in convenience and grocery store aisles. Scientists have linked a flame-retardant ingredient, brominated vegetable oil (BVO), to bromine poisoning in people who drink large amounts of certain sports drinks and sodas. BVO is found in Gatorade Thirst Quencher Orange, Powerade Strawberry lemonade, and sodas like Mountain Dew. The ingredient isn't necessary, but is used for cosmetic reasons because it keeps the artificial flavors from separating in the bottle.
