How to Remove Microplastics From Blood: Can Therapeutic Plasma Exchange Help?

There is no proven, everyday intervention for removing microplastics from human blood. Researchers are still working out what microplastic accumulation in tissue means clinically, let alone how to address it. Therapeutic plasma exchange (TPE) is discussed in this context because it physically removes and replaces the plasma portion of blood, but no published human trial has measured microplastic particle counts before and after TPE. The closest data comes from Extension Health, which reported a 77% reduction in BPA, a plastic-derived chemical, after TPE. That is a different measurement. Here is what the science shows and where it falls short.

For longevity-focused TPE in NYC, this is an elective, self-pay procedure, distinct from established medical uses of plasmapheresis such as myasthenia gravis, Guillain-Barre syndrome and CIDP. If you are considering it for microplastic or inflammatory burden, start with a physician consultation and baseline labs. Our therapeutic plasma exchange service page explains the program.

Why Microplastics in Blood Are a Real Medical Concern

Microplastics were first reported in human blood in a 2022 study published in Environment International. Since then, researchers have reported microplastic particles in other human tissues, including placenta and, more recently, brain tissue. Detection relies on specialized analytical methods, and the measurement techniques themselves are still debated, so concentrations and their clinical significance remain uncertain.

Laboratory and cell-model studies link microplastic exposure to oxidative stress and inflammatory responses. Whether those findings translate to the inflammatory burden we measure in patients is still being worked out. But the concern is not hypothetical: these particles are in human tissue, and asking what to do about them is legitimate. It is also fair to say no one can currently tell you a safe or unsafe blood level, and that no validated clinical test exists to give an individual patient a reliable number.

What TPE Actually Does to Your Plasma

Plasma is the liquid portion of blood, roughly 55% of its volume. Blood cells are suspended in it, and it carries proteins, hormones, lipids, waste products and, it turns out, environmental contaminants such as plasticizers.

During TPE, blood is drawn continuously into an apheresis machine, which separates plasma from your blood cells. The plasma, along with whatever it carries, is discarded and replaced with an albumin-based solution. Your cells are returned to you. For more than 50 years the procedure has been used to remove antibodies causing autoimmune damage and abnormal proteins causing blood viscosity problems. The longevity application extends the same principle: remove accumulated plasma burden and replace it with clean fluid.

For microplastics, the reasoning goes like this. If some portion circulates in the plasma fraction, and TPE removes and replaces plasma, then TPE may reduce circulating levels. That is mechanistically reasonable. But it is a hypothesis, and there is a real complication: it is not established how particles distribute between plasma and the cellular fraction of blood, which affects how much any plasma-based procedure could remove. That distinction matters for anyone making a $10,000-plus decision. For the full picture of how sessions work, see our guide to TPE clinics and what to ask in NYC.

The Evidence Gap: What Is Proven and What Isn’t

No published human trial has directly measured microplastic particle counts before and after TPE. That study needs to be done. I will not tell you it has been proven when it has not.

The closest data is a BPA result. Extension Health, one of the NYC clinics offering TPE for longevity, reported a 77% reduction in BPA (bisphenol A) after TPE. BPA is an endocrine-disrupting chemical that leaches from plastics. It is a small molecule, not a microplastic particle, so the result is directionally interesting but not the same measurement.

The 2025 Aging Cell trial measured something else. The Buck Institute and Circulate Health trial, a randomized, placebo-controlled study of 42 healthy adults over 50, measured biological age with epigenetic clocks. TPE with IVIG produced an average 2.61-year reduction, and TPE alone produced 1.32 years. It was not a microplastics study. It shows that removing and replacing plasma can shift aging biomarkers, which is consistent with, but does not prove, the idea that accumulated circulating burden contributes to biological aging. Our analysis of the 2025 clinical trial covers what it did and did not show.

A microplastics-specific study is still needed. I want that on the record.

Why Diet and Lifestyle Cannot Remove Microplastics Already in Your Bloodstream

Most online advice on microplastics is exposure reduction: filter your water, avoid heating food in plastic, choose glass or stainless steel and eat less ultra-processed food. That advice is reasonable. It works on intake, reducing what enters your body going forward, and it does nothing about particles already circulating.

The liver and kidneys are built to handle small molecules and water-soluble compounds, not particles suspended in plasma, which do not metabolize the way many toxins do. Fiber supports excretion of certain compounds through the gut, but that is a different mechanism from clearing particles from blood plasma.

Lifestyle changes are non-negotiable, and they address a different problem than TPE does. They are not competing approaches. If you have spent years eating clean, filtering water and minimizing plastic exposure, and you still have elevated inflammatory markers or unexplained oxidative burden, the question of what is already circulating is worth asking, ideally with data.

What About Sauna, Supplements and “Detox” Protocols?

No human trial shows that saunas, supplements, chelation or general cleanses remove microplastics from blood, and marketing that implies otherwise is ahead of the evidence. TPE belongs to a different category from a detox cleanse: it is a regulated medical procedure with a long clinical history in serious autoimmune and neurological conditions. That category difference is about mechanism and medical oversight, not proof of benefit for this use. Whether it reduces microplastics remains unproven.

Who Might Reasonably Consider TPE for Toxin or Inflammatory Burden

Not everyone concerned about microplastics is a reasonable TPE candidate. The patients I would consider are:

• Adults over 50 with documented elevated inflammatory markers that have not resolved with lifestyle optimization
• Patients with a known high environmental exposure history, such as occupational chemical exposure or documented water contamination
• People who have already optimized sleep, diet, exercise and stress and still have residual inflammatory or oxidative burden their labs cannot explain
• Patients willing to measure: a baseline panel before the first session and tracked markers after each one

The patients who are not good candidates for this reason are young, healthy people looking for a precautionary shortcut, or anyone unwilling to do baseline lab work. TPE without measurement is an expensive guess. With measurement, it becomes a tracked clinical intervention. Screening also matters for safety, so read who should and should not have TPE.

What We Do at Liondale

Before a first session, we run a baseline panel covering CRP, IL-6, fibrinogen, metabolic markers and lipids. Where clinically relevant, we include toxin burden assessments. TPE at Liondale is performed under Dr. Bissoon’s direct oversight with a trained apheresis nurse, taking two to three hours per session. Post-treatment labs run after each session to show what changed.

Validated clinical microplastic testing for individual patients is not yet available at scale. If that changes, we will add it. Meanwhile we track markers that microplastic accumulation is hypothesized to worsen: inflammatory burden, oxidative stress indicators and metabolic health. Changes in those markers are useful clinical signals, but they are indirect indicators, not proof that microplastics specifically were reduced, and we discuss them that way. The full approach is described in how Liondale tracks TPE results.

Patients who raise this concern often describe ongoing fatigue that has not responded to clean eating or better sleep, brain fog, slower exercise recovery and a sense that their baseline shifted without explanation. Those are nonspecific symptoms with many possible causes, which is exactly why the first step is a history and baseline labs, not a procedure. We are a Circulate Health partner, and our protocols are informed by the methodology used in the 2025 Buck Institute trial. If you are deciding among approaches, see TPE compared with NAD+, ozone, stem cells and peptides.

What to Bring to a Consultation

Bring recent bloodwork if you have it, particularly inflammatory markers, a metabolic panel and any toxin or heavy metal testing. Bring a list of your current medications and supplements, and describe your specific concerns, including any known exposure history. The consultation is a clinical conversation, not a sales presentation. To understand cost before you book, see TPE cost in NYC.

How to Read Claims About Microplastic Removal

Because this topic is new, it attracts confident claims that go beyond the data. A few questions help you evaluate them. Was microplastic actually measured, or was something else measured, such as a chemical or a symptom score? Was the measurement made before and after treatment in the same people? Was the method validated, and by whom? Were the results published where others can examine them? Be cautious when a clinic implies certainty about removal, and equally cautious when someone dismisses the question entirely. The honest position today is that the idea is plausible, the direct evidence is missing and the most useful thing a patient can do is measure what is measurable. That means tracking inflammatory, oxidative and metabolic markers, reducing everyday exposure and revisiting the question as research develops. We will update this page as better data becomes available, and patience is a reasonable position until then. In the meantime, our TPE service page describes what the procedure involves.

Frequently Asked Questions

Can plasma exchange remove microplastics?

It is biologically plausible but unproven. Microplastics have been detected in blood, and TPE removes and replaces the plasma portion of blood, so circulating levels might decrease. No published human study has measured particle counts before and after TPE. The closest data is Extension Health’s 77% BPA reduction, and BPA is a chemical, not a particle.

Is TPE a detox?

It is more accurately described as a medical procedure that removes and replaces plasma. It is not a cleanse or supplement. Whether it lowers specific environmental contaminants is being studied, and we do not promise specific detoxification outcomes.

How is this different from a detox cleanse or supplement?

TPE physically removes and replaces the plasma portion of your blood under physician supervision, and has been used in hospital medicine for over 50 years for serious autoimmune and neurological conditions. No supplement, cleanse or chelation protocol works by that mechanism.

What about the BPA data from Extension Health?

It is relevant and directionally supportive. BPA is an endocrine disruptor that leaches from certain plastics and circulates in plasma, and the clinic reported a 77% reduction after TPE. The gap between BPA reduction and microplastic particle reduction is real, because BPA is a small molecule and microplastics are particles.

Can I test my blood for microplastics?

Validated clinical microplastic testing for individual patients is not yet widely available. Research methods exist, but they are not standardized for routine care, so we track inflammatory, oxidative and metabolic markers as indirect indicators instead.

Can lifestyle changes remove microplastics already in my body?

Exposure reduction lowers future intake and is worth doing. No human evidence shows that diet, sauna or supplements clear particles already circulating in blood.

How much does TPE cost?

A single session runs between $6,000 and $15,000 depending on the clinic and protocol, and ongoing programs commonly cost $12,000 to $36,000 or more per year. It is not covered by insurance for longevity use. See the TPE cost page and our NYC provider comparison.

How often would I need treatment for this purpose?

Most patients start with an initial series of three to six sessions, then move to monthly or quarterly maintenance based on their markers. There is no published protocol specifically for microplastics reduction, because that study has not been done.

Is TPE safe?

It has a strong safety record in medical settings, with serious adverse events reported in roughly 0.12% of procedures in large retrospective studies, but it is still a real procedure with real risks. Patients with bleeding disorders, clotting factor deficiencies, hemodynamic instability or albumin allergy are not candidates.

What should I bring to a consultation?

Recent bloodwork, a list of current medications and supplements, and your specific health concerns, including any exposure history.

If you are concerned about microplastic burden or circulating inflammatory load, schedule a consultation. You can also read more about therapeutic plasma exchange at Liondale Medical.
