You have probably heard the term “forever chemicals” in the news. Maybe you caught a headline about contaminated drinking water, or a story about PFAS being found in rain falling over the Arctic. You might have thought: that sounds bad, but surely it does not apply to me.
Here is the reality. According to data released by the EPA in 2025, approximately 165 million Americans — more than half the country — are drinking water contaminated with PFAS. A U.S. Geological Survey study found PFAS in nearly half of all tap water samples tested nationwide. These chemicals have been detected in the blood of 97% of Americans who have been tested. They have been found in Arctic ice, in the deepest ocean trenches, in rainwater on every continent, and in the umbilical cord blood of newborns. They are called “forever chemicals” because they do not break down. Not in the environment. Not in your body.
And yet, most people have never had a single conversation with a doctor about their PFAS exposure. There is no standard screening. There is no conventional protocol. The conventional medical system has largely treated this as an environmental policy problem rather than a personal health problem — which means that millions of people are carrying a significant chemical burden that is quietly driving inflammation, hormonal disruption, immune dysfunction, and increased cancer risk, with no awareness and no support.
That is what this article is about. Not to alarm you — but to actually explain what PFAS are, what they do inside the body, how you can find out what your personal burden looks like, and what you can do to support your body’s ability to clear them. Because the body can clear them. It just needs the right support and the right conditions.
What Are PFAS — and Why Are They Called “Forever Chemicals”?
PFAS stands for per- and polyfluoroalkyl substances. It is an umbrella term for a family of more than 15,000 synthetic chemical compounds that have been manufactured and used in industrial and consumer products since the 1940s. The defining characteristic of all PFAS is the carbon-fluorine bond — one of the strongest chemical bonds in nature. This bond is so stable that it resists heat, water, oil, and biological degradation. It does not break down under normal environmental conditions. It does not break down in the human body. This is precisely what made PFAS so commercially valuable — and precisely what makes them so dangerous.
PFAS were engineered to make things non-stick, water-resistant, stain-resistant, and heat-resistant. They work exceptionally well for these purposes. The problem is that their stability means they persist indefinitely wherever they end up — in soil, water, air, wildlife, and human tissue.
The most well-studied PFAS are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid) — the long-chain varieties used in Teflon non-stick coatings and Scotchgard fabric protector, respectively. Both have been phased out in the United States due to regulatory pressure, but they remain in the environment and in human bodies because they accumulated over decades. The chemical industry replaced them with shorter-chain PFAS (such as GenX and PFBS), which were initially marketed as safer alternatives — but emerging research suggests they carry similar health risks and may be even more mobile in the environment.
Common sources of PFAS exposure include:
- Drinking water — the primary route for most Americans; contamination is widespread near military bases, airports, and industrial sites that used PFAS-containing firefighting foam (AFFF), but also in municipal water systems far from obvious point sources
- Non-stick cookware — Teflon and similar coatings release PFAS when scratched or heated above 500°F; even lower temperatures can cause off-gassing
- Food packaging — fast food wrappers, microwave popcorn bags, pizza boxes, and takeout containers are often coated with PFAS to resist grease and moisture
- Stain-resistant carpets, upholstery, and clothing — PFAS-treated fabrics shed particles and off-gas over time, particularly in indoor environments
- Personal care products — waterproof mascara, long-wear foundation, dental floss, and some sunscreens contain PFAS compounds
- Firefighting foam (AFFF) — communities near military bases and airports have some of the highest documented PFAS contamination levels in the country
- Contaminated food — produce grown in PFAS-contaminated soil, fish from contaminated water, and meat from animals raised near contaminated sites all carry measurable PFAS levels
What PFAS Do Inside the Body
Once PFAS enter the body — primarily through drinking water and food — they are absorbed through the gut and distributed throughout the body via the bloodstream. They bind preferentially to proteins in the blood and accumulate in organs that are rich in these proteins: the liver, kidneys, thyroid gland, and immune tissues. They also accumulate in the lungs, bones, and reproductive organs.
Unlike many fat-soluble toxins that store primarily in adipose (fat) tissue, PFAS are protein-binding. This means they circulate in the blood and accumulate in organs that are actively working — the liver, the thyroid, the immune system — rather than being sequestered in fat. This is part of what makes them so disruptive to active physiological processes.
The biological half-life of long-chain PFAS in the human body ranges from approximately 3.5 years (for PFOA) to 5.4 years (for PFOS). This means that even if you completely eliminated all new exposure today, it would take years for your body to naturally reduce its existing burden by half — and only if the elimination pathways are functioning optimally. Most people are not eliminating efficiently, and most people are continuing to be exposed daily. The result is a slow, steady accumulation over a lifetime.
The Thyroid Connection
The thyroid gland is one of the most vulnerable organs to PFAS disruption. PFAS structurally resemble thyroid hormones — specifically, they share a similar molecular shape that allows them to interfere with thyroid hormone transport proteins. Research published in Frontiers in Endocrinology and multiple subsequent studies have shown that PFAS can displace thyroid hormones from their transport proteins, alter the conversion of T4 to the active T3 form, and interfere with thyroid hormone receptor signaling at the cellular level.
The clinical result is a pattern that many people in the functional health space will recognize: thyroid labs that look “normal” by conventional standards while the person continues to experience fatigue, weight gain, brain fog, cold intolerance, hair loss, and constipation — the classic symptoms of thyroid dysfunction. Because PFAS disrupt hormone signaling rather than hormone production, standard TSH and T4 tests may not capture the full picture of what is happening at the cellular level.
A 2024 study in Science of the Total Environment found that higher PFAS exposure was associated with significantly increased risk of thyroid cancer — adding to a growing body of evidence linking PFAS to thyroid pathology beyond functional disruption.
Immune Dysfunction and Vaccine Response
One of the most well-documented effects of PFAS exposure is immune suppression. Multiple large epidemiological studies — including research cited by the National Institute of Environmental Health Sciences (NIEHS) — have found that children with higher PFAS blood levels show significantly reduced antibody responses to vaccines. This means PFAS exposure may be literally undermining the immune system’s ability to mount protective responses.
Beyond vaccine response, PFAS have been shown to alter the balance of immune cell populations, increase inflammatory cytokine production, and impair the immune system’s ability to identify and clear abnormal cells — which is one of the proposed mechanisms linking PFAS to cancer risk. The immune system is the body’s primary surveillance and defense system; when it is chronically dysregulated by chemical exposure, the downstream consequences affect virtually every organ system.
Cancer Risk
The International Agency for Research on Cancer (IARC) classified PFOA as a Group 1 carcinogen (known human carcinogen) in 2023, and PFOS as a Group 2A carcinogen (probably carcinogenic to humans). The cancers most strongly associated with PFAS exposure include kidney cancer, testicular cancer, bladder cancer, prostate cancer, and non-Hodgkin lymphoma. Breast cancer and ovarian cancer associations are also being actively studied.
As Dr. Jill Carnahan — who has extensively researched PFAS and co-presented the Vibrant Wellness PFAS panel — has noted, the cancer risk from PFAS is not simply a matter of high-dose industrial exposure. The research increasingly shows that chronic low-level exposure, accumulated over years, is sufficient to meaningfully elevate cancer risk in the general population.
Hormonal and Reproductive Effects
PFAS are classified as endocrine-disrupting chemicals (EDCs) — compounds that interfere with the body’s hormonal signaling systems. Beyond the thyroid, PFAS have been shown to disrupt estrogen and androgen signaling, alter the timing of puberty (with studies showing earlier puberty onset in girls with higher PFAS exposure), reduce fertility in both men and women, and interfere with fetal development during pregnancy.
PFAS cross the placenta and accumulate in breast milk, meaning that PFAS burden is transferred from mother to child both in utero and during breastfeeding. Research has linked prenatal PFAS exposure to low birth weight, altered immune development, and increased risk of metabolic dysfunction in children.
Liver and Metabolic Disruption
The liver is the primary organ for processing and eliminating PFAS, and it bears a significant burden from this work. PFAS accumulate in liver tissue and have been shown to disrupt lipid metabolism — specifically, they interfere with the same pathways that regulate cholesterol and triglycerides. This is why PFAS exposure is consistently associated with elevated LDL cholesterol and triglycerides in epidemiological studies. It is also why PFAS exposure is linked to non-alcoholic fatty liver disease (NAFLD) and insulin resistance.
The liver’s detoxification capacity — its ability to process and eliminate other toxins — is also compromised by PFAS accumulation. This creates a compounding problem: PFAS burden impairs the very organ that is responsible for clearing it, as well as other environmental toxins the body is simultaneously trying to process.

Free Masterclass
Understanding Your Toxic Burden — and What to Do About It
In this free masterclass, Jacob walks through the root-cause framework for understanding environmental chemical burden — including PFAS, heavy metals, mycotoxins, and microplastics — and the step-by-step approach to opening drainage pathways and supporting your body’s natural clearing capacity.
The Industry Cover-Up: What Was Known and When
One of the most important — and most underreported — aspects of the PFAS story is that the health risks were known by the manufacturers decades before they became public knowledge. Internal documents from 3M and DuPont, revealed through litigation and investigative journalism, show that both companies had data indicating PFAS were accumulating in human blood and causing organ damage as early as the 1970s. They chose to suppress this information, continue manufacturing, and lobby against regulation for decades.
This is not a conspiracy theory. It is a matter of public record, documented in court proceedings and reported by outlets including the New York Times, The Intercept, and ProPublica. The pattern is strikingly similar to what happened with tobacco and lead — industries with internal knowledge of harm that prioritized profit over public health, and regulatory systems that were too slow to respond.
The EPA did not set enforceable limits on PFAS in drinking water until April 2024, when it established maximum contaminant levels (MCLs) for six PFAS compounds. These limits are now under political pressure and may be weakened or delayed. The point is not to generate despair about the regulatory system — it is to underscore why waiting for the conventional system to protect you from PFAS is not a viable personal health strategy. The burden of awareness and action falls on the individual, because the system has consistently failed to act in time.
How to Know Your PFAS Burden: Testing That Actually Measures It
This is where the conversation shifts from alarming to empowering. Because unlike many environmental health concerns where you are left guessing, PFAS exposure can be measured. You can actually find out what your personal burden looks like — which specific compounds are elevated, at what levels, and what that means for your health priorities.
The Vibrant Wellness PFAS Chemicals Test is one of the most comprehensive PFAS panels available to practitioners and individuals. As Dr. Jill Carnahan discussed in her presentation on the test, it measures 21 different PFAS biomarkers in urine — including both long-chain varieties (PFOA, PFOS, PFNA, PFDA) and the newer short-chain replacement compounds (GenX, PFBS, PFHxS) that are increasingly prevalent in the environment but less commonly tested. Urine testing captures the PFAS that the body is actively excreting, giving a real-time picture of your current burden and your body’s elimination capacity.
The panel is particularly valuable because it goes beyond just measuring total PFAS exposure. By identifying which specific compounds are elevated, it allows for more targeted support. Different PFAS have different biological half-lives, different organ affinities, and different mechanisms of harm — knowing which ones are most elevated helps prioritize the approach.
The Vibrant Wellness Total Tox Burden Test provides an even broader picture by combining environmental chemicals (including PFAS) with mycotoxins and heavy metals in a single comprehensive panel. Because PFAS, heavy metals, and mycotoxins often co-occur and compound each other’s effects — all three impair liver function, all three drive inflammation, all three disrupt hormones — understanding the full toxic landscape is essential for designing an effective support approach. This is the panel I run with most clients who are dealing with complex, multi-system chronic health challenges.
Your Body Can Clear PFAS — Here Is How to Support That Process
The half-life data on PFAS can feel discouraging at first glance. Three to five years for the body to naturally reduce its burden by half — that sounds like a long time. But that figure assumes no active support, no optimization of elimination pathways, and continued ongoing exposure. When you reduce exposure, open drainage pathways, and use targeted binders and liver support, the timeline improves significantly. And the body’s burden can be meaningfully reduced.
The key insight — one that Dr. Carnahan and other functional practitioners consistently emphasize — is that PFAS elimination is primarily a bile-mediated process. The liver processes PFAS and packages them into bile, which is then released into the small intestine. From there, PFAS can either be excreted in stool or reabsorbed back into the bloodstream through a process called enterohepatic recirculation. This is the same cycle that makes many toxins so persistent in the body. Breaking this cycle — by intercepting PFAS in the gut before they can be reabsorbed — is the most direct and well-supported strategy for accelerating their elimination.
Step 1: Reduce Ongoing Exposure
Before focusing on clearance, reducing the daily input of new PFAS is essential. The highest-impact changes include:
- Filter your drinking water — a high-quality reverse osmosis (RO) system or solid carbon block filter removes the vast majority of PFAS from tap water; this is the single highest-impact exposure reduction step for most people
- Replace non-stick cookware — switch to cast iron, stainless steel, or ceramic; never use scratched or damaged non-stick pans
- Avoid PFAS-treated food packaging — minimize fast food, microwave popcorn, and greasy takeout in coated containers; choose uncoated paper or glass where possible
- Choose PFAS-free personal care products — check labels for “fluoro” ingredients in cosmetics, dental floss, and waterproof products; the Environmental Working Group’s Skin Deep database is a useful reference
- Wash hands before eating — PFAS from treated surfaces, dust, and packaging accumulate on hands and are a significant oral exposure route
Step 2: Support Bile Flow and Liver Function
Because PFAS are primarily eliminated through bile, supporting the liver’s bile production and flow is foundational. The liver needs adequate nutrients to run its Phase I and Phase II detoxification pathways — the two-step process by which fat-soluble toxins are converted into water-soluble forms that can be excreted. Key nutrients include: N-acetyl cysteine (NAC) and glycine as glutathione precursors, B vitamins (particularly B6, B12, and folate) for methylation, magnesium, and antioxidants including vitamin C and resveratrol — both of which were specifically highlighted in the Vibrant Wellness PFAS presentation for their role in supporting the liver’s processing of PFAS.
Choline is particularly important for PFAS clearance. Choline is required for the production of phosphatidylcholine, a key component of bile. Research has shown that PFAS disrupt choline metabolism and bile acid synthesis — meaning that PFAS burden itself impairs the primary mechanism for PFAS elimination. Supplementing choline and supporting bile flow directly addresses this bottleneck.
Step 3: Use Targeted Binders to Interrupt Enterohepatic Recirculation
This is the most direct and evidence-supported strategy for accelerating PFAS elimination. A 2025 study published in Environment International by researchers at the University of Gothenburg found that bile acid sequestrants — specifically cholestyramine and colesevelam — reduced serum PFAS levels by 20–60% in highly exposed individuals over the study period, compared to only about 3% reduction in the untreated group. This is a significant finding: it confirms that intercepting PFAS in the gut before they can be reabsorbed is a viable and effective strategy.
Natural binders work through the same mechanism — they bind to PFAS in the gut and carry them out in stool, preventing reabsorption. The most relevant natural binders for PFAS include:
Activated charcoal — a broad-spectrum binder with a large surface area that adsorbs a wide range of toxins in the gut lumen, including PFAS. Most effective when taken away from food and other supplements to avoid binding nutrients.
Bentonite clay — a negatively charged mineral clay that attracts and binds positively charged toxins and some PFAS compounds. Has been used in traditional medicine for centuries as a gut-clearing agent.
Citrus pectin (modified) — a soluble fiber derived from citrus peel that has been shown to bind to PFAS and other environmental chemicals in the gut. A 2025 Boston University study found that soluble fiber supplementation with meals significantly reduced PFAS levels in participants over four weeks. Modified citrus pectin also feeds beneficial gut bacteria, supporting microbiome recovery.
Fulvic and humic acids (BioActive Carbon Technology) — unlike surface-acting binders that work only in the gut lumen, fulvic and humic acid complexes are bioavailable and can bind toxins at the cellular level. They also support mitochondrial function and cellular repair — important because PFAS generate oxidative stress that damages cells and mitochondria.
Chlorella — a green algae with a fibrous cell wall that binds to heavy metals and some organic toxins including PFAS. Also provides chlorophyll, which supports liver detoxification pathways.
Step 4: Support Elimination Through Sweat and Bowel Regularity
Sweat is a meaningful elimination route for some PFAS compounds. Research published in Public Health (Genuis et al., 2010) found measurable PFAS in sweat samples from individuals using saunas, confirming that the sweat pathway is active for PFAS excretion. Regular sauna use — particularly infrared sauna, which promotes deeper sweating at lower temperatures — is a well-supported adjunct to any PFAS clearance approach.
Bowel regularity is equally important. Since PFAS are primarily excreted through bile into stool, constipation is a significant obstacle to clearance. When stool transit time is slow, PFAS that have been packaged in bile have more time to be reabsorbed before they can be excreted. Adequate hydration, dietary fiber, magnesium, and movement all support regular bowel function and faster transit time.
Step 5: Address the Gut Microbiome
Emerging research suggests that the gut microbiome plays a role in PFAS metabolism and elimination. Certain gut bacteria are capable of biotransforming some PFAS compounds, while PFAS exposure itself disrupts the microbiome — reducing beneficial species and increasing dysbiosis. Rebuilding a diverse, resilient microbiome through targeted probiotics and prebiotic fiber supports both gut barrier integrity (reducing PFAS reabsorption through a leaky gut) and the microbiome’s own contribution to toxin processing.
🌿 Recommended Tools & Resources
These are the specific supplements, protocols, labs, and tools Jacob recommends in connection with the topics covered in this article. All are available through the Beyondetox store or lab portal.
From the Supplement Store
The foundational binder I recommend for anyone beginning to address environmental chemical burden, including PFAS. Powered by BioActive Carbon Technology — a fulvic and humic acid complex — BioToxin Binder works not just in the gut but at the cellular level, binding toxins and supporting cellular repair simultaneously. It is the ideal starting point before progressing to more targeted binders, and it is included in both the Foundation Protocol and the Comprehensive Protocol.
Designed for the intermediate stages of detox support, HM-ET Binder specifically targets heavy metals and environmental toxins — including the PFAS and co-toxins that accumulate alongside them. It combines BioActive Carbon Technology with additional agents targeted at the environmental chemical spectrum. I recommend introducing this after establishing a foundation with BioToxin Binder.
Kidney and liver drainage support is the essential first step before any binder protocol. KL Support provides targeted nutritional support for both organs — the liver’s Phase I and II detox pathways and the kidneys’ filtration function — ensuring that the toxins mobilized by binders have a clear exit route. Because PFAS specifically impair liver function and bile production, supporting these pathways is particularly important in a PFAS clearance approach.
Glutathione is the body’s master antioxidant and the primary molecule used by the liver to conjugate and neutralize environmental toxins including PFAS. PFAS exposure depletes glutathione reserves — which is why replenishing it is a core part of any environmental chemical clearance protocol. Quicksilver Scientific’s liposomal delivery system ensures the glutathione is actually absorbed and utilized at the cellular level, rather than being degraded in the digestive tract as with most oral glutathione supplements.
Recommended Lab Testing
Measures 21 different PFAS biomarkers in urine — including both long-chain varieties (PFOA, PFOS, PFNA, PFDA) and the newer short-chain replacement compounds (GenX, PFBS, PFHxS) that are increasingly prevalent but less commonly tested.

Available through the Beyondetox functional lab portal with practitioner review.
Combines environmental chemicals (including PFAS), mycotoxins, and heavy metals in a single comprehensive panel. Because PFAS, heavy metals, and mycotoxins frequently co-occur and compound each other’s effects — all three impair liver function, all three drive inflammation, all three disrupt hormones — understanding the full toxic landscape is essential for designing a truly effective support approach. This is the panel I run with most clients dealing with complex, multi-system chronic health challenges.
Work One-on-One with Jacob
The protocols and binders in this article are excellent starting points for reducing your PFAS burden. But if you are dealing with complex, chronic symptoms — thyroid dysfunction, immune challenges, hormonal disruption, elevated cancer markers, or cardiovascular concerns — a personalized approach that accounts for your specific lab results, your history, and your body’s unique response will go much further than any fixed protocol. Working one-on-one means your protocol adapts as you do — not a one-size-fits-all supplement schedule, but a dynamic, practitioner-guided process that addresses your actual burden in the right sequence.
- 165 million Americans are drinking PFAS-contaminated water; 97% of Americans tested have PFAS in their blood — this is a population-wide exposure, not a niche concern
