Why the FDA Finally Banned Brominated Vegetable Oil and How Iodine Can Help Detox Your Body

For decades, brominated vegetable oil (BVO) was a common ingredient in citrus-flavored sodas, silently ensuring the tangy taste was perfectly distributed in every sip. However, scientific disfavor has finally caught up with this controversial compound. This year, the FDA officially banned BVO in the United States following mounting evidence of its potential harm.

But here's the kicker — while BVO may now be eliminated from most sodas, its effects could still linger in our bodies. Fortunately, there's a way to detoxify and protect ourselves from these and other harmful halides. Enter iodine, a critical mineral with powerful detoxifying abilities.

What is BVO and Why Was it Used?

BVO, short for brominated vegetable oil, is a modified vegetable oil containing bromine atoms. Since the 1930s, it has been used as an emulsifying agent in citrus-flavored sodas to keep the flavor evenly mixed, preventing it from separating or floating to the top. But while it earned a spot as a "useful" additive in beverages, its safety was always in question.

The Risks of BVO

Studies show that BVO can accumulate in the body's fat tissues. Bromine, a key component of BVO, is known to interfere with iodine’s essential role in the thyroid gland. Iodine supports thyroid hormone production, which regulates metabolism, energy, and many other bodily functions. Bromine’s competition with iodine in the body may contribute to thyroid dysfunction and other endocrine issues.

Early studies found bromine residues in human tissues, raising concerns about long-term exposure. Subsequent animal studies linked high concentrations of BVO to heart issues and behavioral problems. Despite these alarming findings, it took decades for the FDA to collect enough evidence from more recent studies to justify a nationwide ban.

Before the ban, BVO had already been prohibited in several countries, including Japan, India, and the European Union. Companies like PepsiCo and Coca-Cola, anticipating regulatory action, had phased out BVO from their products over the past decade. Although the ban aims to protect public health moving forward, traces of bromine could remain stored in your body if you've consumed BVO-laden sodas or foods in the past.

Understanding Endocrine Disruptors and Halides

The issues with BVO aren’t limited to bromine alone. Bromine is part of a group of chemicals called halides, which include fluoride (commonly found in tap water) and chlorine. These substances are notorious endocrine disruptors, meaning they can interfere with hormonal balance in the body.

Halides often attach to the same receptor sites as iodine in crucial areas such as the thyroid, breasts, and ovaries. When halides occupy these sites, they block iodine from performing its vital functions. Over time, high halide levels have been associated with health problems like ovarian cysts, uterine fibroids, fibrocystic breast disease, and even certain cancers, such as breast and prostate cancer.

But there’s good news—iodine can help displace harmful halides and restore balance (1). 

Iodine Can Help Your Body Detox from Halides (Fluoride, Bromide, and Chlorine)

Iodine isn’t just crucial for thyroid health; it’s also a detoxifying powerhouse. By competing for the same receptor sites as halides, iodine helps flush them out of the body. This detoxification process is essential for reducing the harmful effects of halides and promoting overall hormonal health.

Studies suggest that sufficient iodine intake can:

• Displace bromide, fluoride, and chlorine from their receptor sites in the body.
• Help combat conditions linked to halide exposure, such as thyroid disorders, ovarian cysts, and fibrocystic breast disease.
• Reduce the risk of cancers associated with high halide levels, such as breast, ovarian, and prostate cancer.

Xenoestrogens

It can also help the body eliminate xenoestrogens—synthetic compounds that mimic estrogen in the body. These chemicals, such as BPA (commonly found in plastics), have been linked to breast cancer and other hormonal imbalances. They also include any agent that interferes with the production, transport or metabolism of hormones in the body. As noted by Gupta and Gupta, "Metallo-estrogen, an entirely new class of cancer-causing estrogens...bind to cellular estrogen receptors and can mimic actions of physiological estrogens" (3). 

By binding to xenoestrogens, iodine aids their elimination, supporting hormonal stability and reducing the risk of estrogen-related health issues.

Iodine’s Role in Chelating Heavy Metals Like Mercury and Aluminum

Heavy metals—including mercury, lead, cadmium, and aluminum—are dangerous pollutants linked to serious health concerns. These metals can accumulate in the body, leading to toxicity. Fortunately, iodine supplementation may help by acting as a chelating agent. Chelation is the process in which certain substances bind to heavy metals, aiding their elimination from the body.

Renowned iodine expert Dr. David Brownstein has highlighted iodine's ability to bind with mercury, stating, “Iodine is a chelator of mercury. It will bind with mercury and allow the body to release [it].” This is backed by research indicating that iodine supplementation can significantly enhance the excretion of harmful metals like mercury, lead, and cadmium through urine. While further studies are needed to solidify these findings, anecdotal evidence and initial research suggest exciting possibilities for iodine as a detoxifier.

Iodine may also bind with aluminum, though this process appears to occur more gradually. Supporting this claim, studies like those from the Journal of Environmental and Public Health suggest that iodine plays a valuable role in mobilizing and excreting these toxins. Together, these findings position iodine as a promising tool for reducing heavy metal toxicity.

Iodine as a Detoxifier for Vaccine-Related Toxins

Some individuals have explored iodine’s potential for helping remove toxins from vaccines, including residual heavy metals like mercury and aluminum. For those concerned about the possible side effects of certain vaccines, iodine could offer a pathway for detoxification. By binding to toxic substances, it may assist the body in eliminating harmful residues often implicated in inflammatory processes. While more scientific evidence is necessary for this specific application, early insights are encouraging.

Interestingly, during the global vaccination drive following the COVID-19 pandemic, discussions around iodine’s detoxifying properties gained traction. A 2021 article in Frontiers in Pharmacology discussed nutritional support during vaccine-related inflammatory responses. Although iodine wasn’t the primary focus, its role in supporting organs like the liver and kidneys for toxin removal further emphasizes its detoxifying benefits.

Iodine’s Support for Detox Organs

The body relies on essential organs like the liver, kidneys, lymphatic system, and skin to process toxins. Iodine plays an integral role in supporting these systems, ensuring they function optimally to remove harmful substances:

• Lymphatic System: A deficiency in iodine can cause lymphatic congestion, which hampers detoxification. An adequate intake of iodine keeps the lymphatic system functioning effectively. 

• Liver Health: The liver processes thyroxine (T4), a thyroid hormone containing iodine, into its active form, tri-iodothyronine (T3). This conversion is vital for maintaining energy production and metabolic health. Without sufficient iodine, this process slows down, affecting the liver's detoxification efficiency (2). 
• Kidney Function: The kidneys are closely tied to thyroid health, and iodine is crucial for thyroid function. Research published in Seminars in Nephrology highlights that hypothyroidism—often due to iodine deficiency—commonly coexists with chronic kidney disease (CKD). Supplementing with iodine may help optimize thyroid function and, by extension, kidney health.

What Can You Do?

If you’re concerned about lingering BVO or other halides in your system, focusing on iodine intake is a proactive first step. Here’s how you can incorporate more iodine into your diet and lifestyle:

1. Eat Iodine-Rich Foods

Include foods like seaweed, fish, dairy, and iodized salt in your diet to boost iodine levels. Seaweed, in particular, is one of the best sources of natural iodine.

2. Consider Iodine Supplements

If dietary intake doesn’t suffice, high-quality iodine supplements can help ensure you’re meeting your daily requirements. However, consult a healthcare provider before starting any new supplement.

3. Filter Your Water

Install a water filtration system to remove fluoride and chlorine from your drinking water—two halides that can compete with iodine in your body.

4. Avoid Excess Bromine Exposure

Stay vigilant about products that may still contain bromine. Check labels on food, beverages, and even personal care items for potential sources of this harmful chemical.

5. Get Regular Checkups

Talk to your healthcare provider about hormone testing if you suspect iodine deficiency or endocrine issues.

Moving Forward Without BVO

With BVO finally banned across the U.S., consumers can breathe a sigh of relief knowing one less harmful additive hides in their food. Major beverage manufacturers have already replaced BVO with safer alternatives, ensuring citrus-flavored drinks remain tangy and enjoyable.

But the conversation doesn’t end here. Protecting your health goes beyond eliminating single ingredients like BVO. By understanding the broader issue of toxic minerals, such as the use of bromine, and fluoride in food products, and leveraging the detoxifying power of iodine, you can take control of your hormonal health and well-being.

Your body deserves balance—and now’s the time to start restoring it. Take action today by incorporating iodine into your routine and seeing the difference it can make for your health.
