What is Brominated Vegetable Oil (BVO)?
Brominated vegetable oil (BVO) is a food additive used to stabilize and emulsify flavorings in beverages, particularly those with a citrus base. BVO prevents flavor oils from separating from the water and rising to the surface, ensuring a consistent, cloudy appearance. It is made by modifying vegetable oil with bromine. Though once considered 'Generally Recognized As Safe' (GRAS) by the FDA, concerns about its safety have persisted for decades, leading to international restrictions and, ultimately, a ban in the United States.
The Health Concerns Associated with BVO
Concerns about the safety of BVO have been growing for decades, primarily because bromine can accumulate in body fat, liver, heart, and brain tissue. While the risk from moderate consumption is considered low, excessive intake has been linked to potential health issues. Animal studies have shown that high levels of exposure can cause damage to the thyroid gland. Some of the potential negative health effects linked to overexposure include:
- Damage to the central nervous system
- Memory loss
- Headaches
- Nausea
- Loss of muscle coordination
- Irritation of the skin and mucous membranes
These concerns, coupled with increasing pressure from advocacy groups and public awareness, prompted regulatory action by the FDA and individual states.
Which Drinks Historically Contained BVO?
Historically, BVO was most prevalent in citrus-flavored soft drinks and sports drinks, with many major brands phasing it out over the years. Some of the most well-known examples include:
- Mountain Dew: PepsiCo removed BVO from this product in 2020 after a public petition gained significant attention.
- Gatorade: PepsiCo phased BVO out of Gatorade products in 2013.
- Powerade and Fanta: Coca-Cola announced the removal of BVO from all its products, including Powerade and Fanta, in 2014.
- Sun Drop: This brand, made by Keurig Dr Pepper, was one of the last major products to contain BVO. A company spokesperson announced they were actively reformulating the product, with completion expected by the end of 2024 to comply with the new federal ban.
- Store Brands: Smaller grocery store brands and regional sodas, including certain varieties from Great Value (Walmart), Food Lion, and Giant, have historically listed BVO as an ingredient.
How to Check for BVO
With the nationwide ban in effect, identifying BVO in new products should be a thing of the past. However, because manufacturers have a one-year compliance period (until August 2025), older inventory containing BVO might still be on store shelves.
- Read the ingredient list: The most reliable method is to check the ingredient label. BVO must be explicitly listed as "brominated vegetable oil" or a brominated version of a specific oil, such as "brominated soybean oil".
- Check for citrus flavor: BVO was most commonly used in citrus-flavored beverages, so these are the products to scrutinize most carefully.
- Note product appearance: While not foolproof, some drinks with BVO have a characteristic cloudy appearance due to the emulsification. If a citrus-flavored drink is particularly opaque, it's worth checking the label.
Comparison of BVO-Containing and BVO-Free Drinks
| Feature | Drinks Containing BVO (Historically) | BVO-Free Drinks (Modern) |
|---|---|---|
| Primary Function | Emulsifier to prevent flavor separation | Often use alternative emulsifiers or have different formulations |
| Appearance | Often appears cloudy and consistent | Appearance varies; may be clear or have different stabilizers |
| Key Brands | Sun Drop, some store-brand orange sodas | Major brands like Coca-Cola, Pepsi, most Gatorade and Fanta products |
| Regulatory Status | FDA banned nationwide as of 2024 (compliance 2025) | Widely compliant with global and national food safety standards |
| Health Concerns | Linked to thyroid and neurological issues in animal studies | Not associated with BVO-related health risks |
| Labeling | Explicitly lists "Brominated Vegetable Oil" | Lists alternative, approved ingredients like glycerol ester of wood rosin |
What to Choose Instead of BVO Drinks
For consumers looking to avoid BVO and other controversial food additives, there are plenty of healthy and flavorful alternatives:
- Water with fresh fruit: Infusing water with fresh citrus fruits, berries, or cucumber is a simple, delicious, and healthy alternative to flavored sodas.
- Seltzer or sparkling water: Mixing unflavored seltzer with a splash of 100% fruit juice offers a fizzy drink without added chemicals.
- Unsweetened tea or coffee: These offer flavor variety without the need for synthetic additives or excessive sugar.
- Homemade sodas: Using a SodaStream or similar machine, you can create your own carbonated beverages with natural flavorings.
The Path to the Ban: A Timeline of BVO Regulation
The FDA's final rule revoking authorization for BVO's use in food, which was finalized on July 3, 2024, marks the culmination of decades of regulatory review.
- 1958: The FDA initially designates BVO as "Generally Recognized As Safe" (GRAS).
- 1970: Toxicity studies raise concerns, leading the FDA to remove BVO from the GRAS list and reclassify it as a food additive with interim authorization at limited levels.
- 2014: Public pressure and growing health evidence prompt the FDA to re-evaluate BVO's safety and commission new studies.
- 2022: A study co-conducted by the FDA and NIH reveals potential adverse health effects on rodents at realistic exposure levels.
- 2023: California passes the California Food Safety Act, banning BVO and three other additives, effective 2027.
- July 2024: The FDA issues a final rule banning BVO nationwide, effective August 2, 2024, with a one-year compliance period.
Conclusion
The landscape of beverages is changing, with brominated vegetable oil (BVO) officially banned by the FDA due to safety concerns identified in recent animal studies. While major brands like Pepsi and Coca-Cola removed BVO from their products years ago, some smaller, store-brand citrus drinks may still exist on shelves until the August 2025 compliance date. Consumers should practice due diligence by checking ingredient lists for the term "brominated vegetable oil" to ensure they are purchasing products free of this controversial additive. For long-term health, opting for water or naturally flavored drinks remains the safest choice.
