The Controversy Behind Brominated Vegetable Oil (BVO)
Brominated vegetable oil, or BVO, is a food additive used to keep citrus flavorings from separating and rising to the surface in drinks. In the United States, its use was granted "interim status" by the FDA in 1977. However, in several other countries, including those in the European Union, India, and Japan, BVO was banned from food products long ago due to safety concerns.
The ingredient came under intense scrutiny in 2012 when a teenager’s online petition brought it to the public's attention. The petition highlighted that BVO is patented as a flame retardant and pointed to research suggesting potential health risks associated with high consumption.
Health Concerns Associated with BVO
While research on the health effects of BVO is not extensive, some studies and case reports have raised concerns. Concerns include:
- Bromide Intoxication: There are at least two documented cases of heavy drinkers of BVO-laced beverages experiencing bromide intoxication, which can cause neurological symptoms like memory loss.
- Accumulation in Tissue: Studies, including animal trials, showed that bromine from BVO accumulates in human and animal tissue, particularly in fat and the thyroid gland, raising long-term health questions.
- Potential Thyroid Impacts: An animal study published by the FDA in 2022 confirmed that at high exposure levels, the thyroid is a target organ for potential negative health effects in rodents.
How Gatorade Changed Its Formula
In response to mounting public pressure from the 2012 petition and a shift in consumer perception toward more natural ingredients, PepsiCo announced in January 2013 that it would remove BVO from its Gatorade sports drinks. The company had already been working on a replacement for some time, and within months, the reformulated product began to appear on store shelves.
This move by Gatorade's parent company was a significant win for consumer activism. It led to a broader industry shift, with Coca-Cola following suit in 2014 by removing BVO from its products, including Powerade and Fanta.
BVO Regulations: A Timeline of Change
The removal of BVO from sports drinks like Gatorade was an important industry development, but regulatory changes have since codified the end of its use in the U.S.
- 2013: PepsiCo announces BVO removal from Gatorade in response to a public petition.
- 2014: Both PepsiCo and Coca-Cola announce plans to remove BVO from all their products.
- 2023: California passes the California Food Safety Act, becoming the first state to ban BVO, along with three other additives, starting in 2027.
- 2024: Following a proposal in November 2023, the FDA officially revokes its authorization for the use of BVO in food, with the ban taking effect on August 2, 2024.
The FDA's Official Stance
In a news release accompanying the final ban, the FDA stated it had concluded that "the intended use of BVO in food is no longer considered safe" based on studies showing potential for adverse health effects in humans. This action provides a clear regulatory framework, removing BVO from the food supply altogether, regardless of individual company policies.
Comparison: BVO-Era Gatorade vs. Modern Gatorade
Here is a comparison of older Gatorade formulations that contained BVO and the product found on shelves today:
| Feature | BVO-Era Gatorade (Pre-2013) | Modern Gatorade (Post-2013) |
|---|---|---|
| Emulsifier | Brominated Vegetable Oil (BVO) | Sucrose Acetate Isobutyrate, or gum arabic and glycerol ester of rosin. |
| Bromine Source | Contained BVO, a source of bromine. | Does not contain BVO; no added bromine. |
| Public Perception | Gaining negative perception due to BVO concerns. | Improved perception as a cleaner label sports drink. |
| Regulatory Status | Allowed by FDA with 'interim status'. | BVO is now banned by the FDA. |
| Flavors Affected | Primarily citrus flavors like Orange and Lemonade. | No flavors contain BVO. |
Hydration Beyond Sports Drinks
For most people engaged in light exercise or daily activity, plain water is the best and most effective method of hydration. Sports drinks like Gatorade are specifically formulated for athletes engaged in intense, prolonged physical exertion, providing carbohydrates for energy and electrolytes like sodium and potassium lost through sweat. Their high sugar content can be detrimental to those who are not replenishing electrolytes lost during vigorous exercise and are not part of a healthy daily diet.
If you are looking to supplement your hydration beyond water, consider these options:
- Plain water: Still the best choice for everyday hydration and most exercise.
- Electrolyte water: Often contains electrolytes but with minimal to no sugar, suitable for less intense rehydration needs.
- Coconut water: A natural source of electrolytes, particularly high in potassium.
- Homemade electrolyte drink: Mix water with a pinch of salt and a small amount of fruit juice for a simple, natural alternative.

Conclusion
The question "Is bromine in Gatorade?" now has a definitive "no." The ingredient brominated vegetable oil (BVO), which contained bromine, was removed by PepsiCo in 2013 due to consumer pressure. This decision anticipated broader regulatory changes, culminating in the FDA’s official ban on BVO in August 2024. While the removal of this controversial additive improves the product's safety profile, it doesn’t change the fact that sports drinks are designed for specific athletic needs due to their high sugar and electrolyte content. For general hydration and a balanced nutritional diet, most people are better served by water and a diet rich in fruits, vegetables, and whole foods.
