Supplement Shows Promise in Removing Persistent PFAS Chemicals

Fiber Supplements Show Promise in Reducing ‘Forever Chemicals’ in the Body, BU Researcher Finds

BOSTON, MA – A Boston University researcher is making headway in the fight against PFAS – per- and polyfluoroalkyl substances, often called “forever chemicals” – with a surprisingly simple potential solution: fiber supplements. Dr. Caroline Schlezinger, a research assistant professor at BU’s School of Public Health, has been investigating whether gel-forming fibers can bind to PFAS in the digestive system and help the body eliminate them.

Initial pilot studies focused on cholestyramine, a medication typically used to lower cholesterol, showed promising results in reducing PFAS levels. Though, Schlezinger’s team is now expanding the research to explore more accessible options.

“We want to figure out if we’re right: Is the hypothesis correct when we are testing it in a very controlled scenario?” Schlezinger stated.

The current research involves testing seven different diets and gel-forming fibers, including psyllium – a key ingredient in Metamucil – to determine the most effective approach. Schlezinger emphasizes that a supplement is a more practical solution than drastically altering one’s diet.

“What is exciting about this potential intervention is its accessibility,” she explained. “It’s feasible. I bought every single supplement, every single fiber that I’m testing, on Amazon.”

PFAS are widespread environmental contaminants found in everything from non-stick cookware to firefighting foam.Exposure has been linked to a range of health problems, and concerns are growing, particularly for populations near military bases – identified as a potential risk factor for higher PFAS levels. schlezinger is collaborating with Chelsea simone, an Army veteran and nurse practitioner, to address the specific concerns of veterans.

The research comes at a critical time, as the Trump administration recently announced rollbacks on limits for PFAS in drinking water. Schlezinger calls the move a “mistake,” but notes the process is ongoing.

While acknowledging the research is still in its early stages, Schlezinger is optimistic. She cautions against expecting a rapid fix, but highlights the potential for a simple, affordable intervention. She and her husband have been personally testing oat beta-glucan for over two years, reporting positive effects on cholesterol levels.

“I don’t want to imply that you’re going to take a fiber supplement for a few months and the PFAS are going to be gone,” Schlezinger clarified.”But it’s doable.”

Significant Note: Individuals should consult with a doctor before considerably increasing their fiber intake.

understanding PFAS and the Growing Concern

PFAS (per- and polyfluorinated alkyl substances), also historically known as PFCs, are a group of man-made chemicals that have gained significant attention due to their persistence in the environment and potential health effects.These “forever chemicals” don’t break down easily and accumulate in our bodies and the environment. Exposure to PFAS contamination is widespread, found in drinking water, food packaging, and various consumer products. Common PFAS chemicals include PFOS, PFOA, and GenX.

The health concerns associated with PFAS exposure are numerous,ranging from immune system suppression and increased cholesterol levels to certain types of cancer. This has driven research into effective methods for PFAS removal and mitigation.

The Role of Chlorella in PFAS Detoxification

Emerging research suggests that certain supplements, particularly chlorella, a single-celled green algae, may offer a promising avenue for reducing PFAS levels in the body. Several studies indicate chlorella’s ability to bind to PFAS compounds in the digestive tract,preventing their absorption and promoting their excretion.

How chlorella Works: A Deep Dive

Chlorella’s unique cellular structure and composition contribute to its potential detoxifying properties:

Cell Wall Binding: The porous cell wall of chlorella acts like a sponge, effectively binding to PFAS molecules.

Enhanced excretion: By binding to PFAS, chlorella facilitates their removal from the body through regular bowel movements.

Antioxidant Properties: Chlorella is rich in antioxidants, which can help mitigate the oxidative stress potentially caused by PFAS exposure.

Gut Health Support: A healthy gut microbiome is crucial for overall detoxification. Chlorella can contribute to gut health, indirectly supporting PFAS elimination.

Research findings on Chlorella and PFAS Reduction

while research is ongoing, initial findings are encouraging.

Human Studies: A pilot study published in environmental Health Perspectives demonstrated that chlorella supplementation substantially reduced serum PFAS concentrations in participants with detectable levels of these chemicals. Participants consumed a specific dosage of chlorella for a defined period, and blood samples were analyzed before and after supplementation.

Animal Models: Studies using animal models have shown similar results,with chlorella management leading to decreased PFAS accumulation in tissues.

Specific PFAS Targeted: Research suggests chlorella may be particularly effective at binding to certain PFAS compounds, like PFOA and PFOS, but further investigation is needed to determine its efficacy against the entire spectrum of PFAS chemicals.

Choosing a high-Quality Chlorella Supplement

Not all chlorella supplements are created equal. To maximize potential benefits, consider these factors:

1. Source: Opt for chlorella grown in a controlled environment, away from potential sources of contamination.
2. Cell Wall Integrity: Look for “broken cell wall” chlorella, as this enhances bioavailability and allows for better absorption of nutrients and binding capacity.
3. Purity Testing: Choose supplements that have been independently tested for heavy metals, pesticides, and other contaminants. Third-party certifications (like USP or NSF) can provide assurance of quality.
4. Dosage: Follow the dosage recommendations provided by the manufacturer or a healthcare professional. Typical dosages range from 2-5 grams per day.

Practical Tips for Reducing PFAS Exposure

Supplementation with chlorella can be a supportive strategy, but reducing overall exposure to PFAS is equally important. Here are some practical steps you can take:

Water Filtration: Invest in a high-quality water filter certified to remove PFAS. Activated carbon filters and reverse osmosis systems are effective options.

Food Choices: Limit consumption of processed foods and fast food, as these often contain PFAS in their packaging.Choose fresh, whole foods whenever possible.

Non-Stick Cookware: Replace non-stick cookware with alternatives like stainless steel, cast iron, or ceramic.

Stain-Resistant Products: Be mindful of stain-resistant treatments on carpets, furniture, and clothing.

Regular Testing: If you live in an area with known PFAS contamination, consider getting your drinking water and blood levels tested.

Potential Side Effects and Precautions

Chlorella is generally considered safe for most people, but some individuals may experience mild side effects, such as:

Digestive Upset: Gas, bloating, or diarrhea can occur, especially when starting supplementation.

Allergic Reactions: Even though rare, allergic reactions are possible.

Medication Interactions: Chlorella may interact with certain medications, such as blood thinners and immunosuppressants.

Important Disclaimer: Always consult with a healthcare professional before starting any new supplement regimen, especially if you have underlying health conditions or are taking medications. This article is for informational purposes only and should not be considered medical advice.
