PepsiCo announced on Friday that it would no longer use an ingredient in Gatorade after consumers complained.
The ingredient, brominated vegetable oil, which was used in citrus versions of the sports drink to prevent the flavorings from separating, was the object of a petition started on Change.org by Sarah Kavanagh, a 15-year-old from Hattiesburg, Miss., who became concerned about the ingredient after reading about it online. Studies have suggested there are possible side effects, including neurological disorders and altered thyroid hormones.
The petition attracted more than 200,000 signatures, and this week, Ms. Kavanagh was in New York City to tape a segment for “The Dr. Oz Show.” She visited The New York Times on Wednesday and while there said, “I just don’t understand why they can’t use something else instead of B.V.O.”
“I was in algebra class and one of my friends kicked me and said, ‘Have you seen this on Twitter?’ ” Ms. Kavanagh said in a phone interview on Friday evening. “I asked the teacher if I could slip out to the bathroom, and I called my mom and said, ‘Mom, we won.’ ”
Molly Carter, a spokeswoman for Gatorade, said the company had been testing alternatives to the chemical for roughly a year “due to customer feedback.” She said Gatorade initially was not going to make an announcement, “since we don’t find a health and safety risk with B.V.O.”
Because of the petition, though, Ms. Carter said the company had changed its mind, and an unidentified executive there gave Beverage Digest, a trade publication, the news for its Jan. 25 issue.
Previously, a spokesman for PepsiCo had said in an e-mail, “We appreciate Sarah as a fan of Gatorade, and her concern has been heard.”
Brominated vegetable oil will be replaced by sucrose acetate isobutyrate, an emulsifier that is “generally recognized as safe” as a food additive by the Food and Drug Administration. The new ingredient will be added to orange, citrus cooler and lemonade Gatorade, as well Gatorade X-Factor orange, Gatorade Xtremo citrus cooler and a powdered form of the drink called “glacier freeze.”
Ms. Carter said consumers would start seeing the new ingredient over the next few months as existing supplies of Gatorade sell out and are replaced.
Health advocates applauded the company’s move. “Kudos to PepsiCo for doing the responsible thing on its own and not waiting for the F.D.A. to force it to,” said Michael Jacobson, executive director of the Center for Science in the Public Interest.
Mr. Jacobson has championed the removal of brominated vegetable oil from foods and beverages for the last several decades, but the F.D.A. has left it in a sort of limbo, citing budgetary constraints that it says keep it from going through the process needed to formally ban the chemical or declare it safe once and for all.
Brominated vegetable oil is banned as a food ingredient in Japan and the European Union. About 10 percent of drinks sold in the United States contain it, including Mountain Dew, which is also made by PepsiCo; some flavors of Powerade and Fresca from Coca-Cola; and Squirt and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.
PepsiCo said it had no plans to remove the ingredient from Mountain Dew and Diet Mountain Dew, both of which generate more than $1 billion in annual sales.
Heather White, executive director at the Environmental Working Group, said of PepsiCo’s decision, “We can only hope that other companies will follow suit.” She added, “We need to overhaul how F.D.A. keeps up with the latest science on food additives to better protect public health.”
Ms. Kavanagh agreed. “I’ve been thinking about ways to take this to the next level, and I’m thinking about taking it to the F.D.A. and asking them why they aren’t doing something about it,” she said. “I’m not sure yet, but I think that’s where I’d like to go with this.”

Correction: January 26, 2013
An earlier version of this article misspelled the surname of the 15-year-old who started a petition on Change.org to end the use of brominated vegetable oil in Gatorade. She is Sarah Kavanagh, not Kavanaugh.
