A 15-Year-Old's Petition Got BVO Out of Gatorade in 2013. The FDA Didn't Finish the Job Until 2024.

In 2012, a ninth grader in Hattiesburg, Mississippi read the ingredient list on a bottle of orange Gatorade and stopped at three words: brominated vegetable oil. She'd seen that same chemical described somewhere else, in a patent for flame-retardant foam. Same compound, different bottle. Sarah Kavanagh started a petition asking PepsiCo to take it out of her favorite drink, and within a year, it was gone from every bottle of Gatorade sold in the U.S.

The federal government took another eleven years to ban that same ingredient from everything else on the shelf. That gap, between one company changing its formula under pressure and the government changing the law for everyone, is where most of the real fight over food additives actually happens. Here's what brominated vegetable oil was doing in your soda, how a teenager beat federal regulators to the punch by over a decade, and what the slow-motion ban after her petition says about who moves first when an ingredient turns out to be a problem.

What BVO Was Actually Doing in Your Soda

Brominated vegetable oil is vegetable oil bonded with bromine atoms, which makes it dense enough to stay mixed into water instead of floating to the surface. Beverage makers started adding it to citrus-flavored drinks in the 1930s to keep the citrus flavoring oils suspended evenly through the liquid, instead of separating into a greasy layer at the neck of the bottle.

It showed up in Gatorade's orange and citrus flavors, in Mountain Dew, Fresca, Squirt, and Powerade. The amount in any single can was small, but bromine builds up in body fat and tissue over time, and animal studies linked high doses to thyroid problems and neurological effects. The FDA never fully approved BVO. Since 1970, it sat in a regulatory holding pattern called interim status, cleared for use while the agency supposedly kept studying it. That interim status lasted 54 years.

Sports drinks matter here specifically because of who drinks them and how much. A ten-year-old finishing a bottle of orange Gatorade after practice takes in the same dose of bromine as an adult would, in a body that weighs a third as much. The FDA's original safety assessments for BVO, done in the 1970s, were built around adult body weight and adult consumption patterns, not a kid restocking a water bottle from a vending machine three times a week.

The Petition That Moved Faster Than the FDA

Kavanagh's petition on Change.org didn't cite a peer-reviewed toxicology study. It pointed out that the U.S. Patent and Trademark Office had BVO on file as a flame retardant for plastics, and asked why an ingredient with that use anywhere was showing up in a sports drink teenagers pack for practice. The petition passed 200,000 signatures within months, and national news picked up the story.

PepsiCo announced it would remove BVO from Gatorade in January 2013, without the FDA requiring anything. Coca-Cola followed in 2014, pulling it from Powerade. Both companies said the ingredient wasn't unsafe at the levels they used and framed the change as responding to what customers wanted. Neither company touched Mountain Dew, Fresca, or Squirt. BVO stayed in all three for another ten years.

Why the Federal Ban Took Until 2024

A company dropping one ingredient from one product line is a decision it can make on its own timeline, in a press release, with no legal process attached. Banning an ingredient outright is different. The FDA has to formally determine it's no longer safe under federal law, which means new toxicology data, a public comment period, and a rule written to survive a legal challenge from the industry it affects.

That evidence came from a study the FDA co-funded with the National Institutes of Health, which found that BVO accumulates in human tissue at levels the agency hadn't accounted for and can affect thyroid hormone levels at exposures closer to what people actually drink. The FDA proposed revoking BVO's approval in November 2023 and finalized the rule in July 2024. It took effect August 2, 2024, with a one-year window for manufacturers to reformulate, relabel, and sell through existing inventory before enforcement began.

California Didn't Wait Either

Seven months before the FDA's final rule, California had already gone further. The California Food Safety Act, signed in October 2023, bans BVO along with potassium bromate, propylparaben, and Red dye 3 starting January 1, 2027, regardless of what the FDA allows in the meantime. Lawmakers pointed out that the European Union, Japan, and India had restricted or banned these same additives years, sometimes decades, earlier.

Whole Foods, Aldi, and Panera had already dropped all four additives from their private-label products and menus before the law passed. The pattern keeps repeating: a company or a state moves first under public pressure, and the FDA's own review process follows years behind, only after enough evidence and enough political weight pile up on top of it.

Read the Label, Then Do Something About It

BVO is off U.S. shelves as of last year, but the ingredients replacing it, mostly ester gum and sucrose acetate isobutyrate, have thinner safety records than you'd want for something standing in for a banned flame-retardant chemical. An ingredient list that no longer says brominated vegetable oil isn't automatically a clean one, and it's worth checking what actually replaced it before assuming the fix is real. Nationally, the compliance deadline already passed in August 2025, so any BVO-labeled product still sitting on a shelf right now is a straight-up violation, not just an outdated formula, and worth flagging directly to whoever runs your school's food service.

Kavanagh wasn't a chemist or a lobbyist when she started reading labels. She was a ninth grader with a petition, and it worked faster than the federal government did. If your cafeteria's vending machines still stock citrus sodas or sports drinks, check the ingredient label yourself and ask your food service director what's actually in this year's formula.
