The ingredient, brominated vegetable oil, had been the target of a petition by a Mississippi teenager, who questioned why it was being used in a drink marketed toward health-conscious athletes. The petition on Change.org noted that the ingredient is linked to a flame retardant and is not approved for use in Japan or the European Union.
In response to customer feedback, PepsiCo said last year it would drop the ingredient from Gatorade. At the time, Coca-Cola declined to say whether it would remove the ingredient from the two flavors of Powerade that contain it as well.
The Food and Drug Administration says brominated vegetable oil is used as a stabilizer for flavoring oils in fruit-flavored drinks. Coca-Cola has said in the past that it uses it to "improve stability and prevent certain ingredients from separating."
