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

There is no proven everyday intervention for removing microplastics from blood. The honest answer is that researchers are still working out what microplastic accumulation in human tissue means clinically, let alone how to address it. Therapeutic plasma exchange is being discussed in this context because it physically removes and replaces the plasma fraction of blood - where microplastics circulate - but a direct human trial measuring microplastic particle counts before and after TPE has not been published. The closest evidence comes from Extension Health, which documented a 77% reduction in BPA (a plastic-derived chemical) after TPE. That is not the same measurement. Here is what the science actually shows, and where it still falls short.

For longevity-focused TPE in NYC: This is an elective, self-pay procedure, distinct from FDA-approved uses of plasmapheresis (myasthenia gravis, Guillain-Barre syndrome, CIDP). If you are considering it for microplastic or inflammatory burden, start with a physician consultation and baseline labs.

Why Microplastics in Blood Are a Real Medical Concern

Microplastics were first detected in human blood in 2022, documented in a study published in Environmental International. That was the first confirmed finding. Since then, researchers have found them in human placenta (2023), brain tissue (2023), and cardiac tissue (2024). Researchers have detected microplastics in these tissues using specialized analytic methods. The concentrations and their clinical significance are still being studied - what this means for long-term health is not yet established, though the research direction is being taken seriously by the scientific community.

What the emerging research suggests about their effects is still early. There is evidence linking microplastic accumulation to oxidative stress and inflammatory responses in cell models. Whether those laboratory findings translate to the clinical inflammatory burden we measure in patients is a question still being worked out. But the concern is not hypothetical. These particles are in human tissue. The question of what to do about them is legitimate.

What TPE Actually Does to Your Plasma

Plasma is the liquid fraction of blood. It makes up roughly 55% of blood volume. Red blood cells, white blood cells, and platelets are suspended in it - but plasma itself is a complex fluid carrying proteins, hormones, lipids, waste products, and, it turns out, environmental contaminants including plasticizers and microplastic particles.

During TPE, your blood is drawn out continuously. An apheresis machine separates the plasma from your blood cells using centrifugation. The plasma - along with everything it is carrying - is discarded. Fresh albumin solution replaces it. Your blood cells are returned to you with the new albumin-based fluid.

The procedure was developed to remove unwanted circulating factors from plasma. For 50-plus years, it has been used clinically to remove antibodies causing autoimmune damage, toxins causing neurological injury, and abnormal proteins causing blood viscosity problems. The anti-aging application is an extension of the same mechanism - remove accumulated plasma burden, replace with clean fluid, let the body's repopulation of that plasma produce a younger-profile fluid over time.

For microplastics specifically: if some portion circulates in the plasma fraction (which is plausible given their detection in blood), and TPE removes and replaces plasma, then TPE may reduce circulating microplastic levels. That hypothesis is mechanistically reasonable. It has not been confirmed in a published human study, and that distinction matters for anyone making a $10,000+ decision.

The Evidence Gap: What's Proven and What Isn't

Let me be clear about what we know and what we do not.

No published human trial has directly measured microplastic particle counts before and after TPE. That study needs to be done. When it is, the results will either support or complicate the mechanistic hypothesis. I am not going to tell you it has been proven when it has not.

The closest data: Extension Health, one of the NYC clinics offering TPE for longevity, published results showing a 77% reduction in BPA following TPE. BPA is bisphenol A, an endocrine-disrupting chemical that leaches from plastics. It is not a microplastic particle - it is a small molecule. But it is a plastic-derived environmental contaminant that circulates in plasma, and TPE removed 77% of it. That is mechanistically consistent with what we would expect for microplastics as well, though direct confirmation is still needed.

The 2025 Aging Cell trial from the Buck Institute and Circulate Health measured something different: biological age, using epigenetic clocks. Forty-two healthy adults over 50, randomized and placebo-controlled. TPE plus IVIG produced an average 2.61-year reduction in biological age. TPE alone produced 1.32 years. That trial was not measuring microplastics - it was measuring the overall anti-aging effect of plasma clearance and replacement. But it demonstrates that removing and replacing plasma produces measurable changes in aging biomarkers, which is consistent with the hypothesis that accumulated circulating burden (including contaminants) contributes to biological aging.

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

Why Diet and Lifestyle Can't Remove Microplastics Already in Your Bloodstream

Most of the advice you will find online for microplastics is exposure reduction: filter your water, avoid heating food in plastic containers, choose glass or stainless steel, eat less processed food. That advice is correct. It is also limited.

Exposure reduction works on intake. It reduces how much microplastic enters your body going forward. It does nothing about what is already in your circulation.

The liver and kidneys filter small molecules and water-soluble compounds. They are not designed to filter plastic particles suspended in plasma. These particles do not metabolize the way toxins do. They do not dissolve. Fiber supports excretion of certain compounds through the gut, but again - that is a different mechanism than clearing particles already circulating in blood plasma.

Lifestyle changes are non-negotiable. But they address intake - what goes in from this point forward. TPE, by removing and replacing plasma, addresses what is already circulating. Whether that includes microplastics specifically remains unproven, but the strategies target different problems. They are not competing approaches. If you have spent years eating clean, filtering your water, and minimizing plastic exposure - and you still have elevated inflammatory markers or oxidative stress burden - the question of what is already in your circulation is worth asking.

Who Might Reasonably Consider This

Not every patient is a reasonable candidate for TPE as a response to microplastics concern. The patients I would consider are:

• Adults over 50 with documented elevated inflammatory markers that have not resolved with lifestyle optimization
• Patients with known high environmental exposure history - occupational chemical exposure, long-term high-plastic-use environments, or locations with documented water contamination
• People who have already optimized sleep, diet, exercise, and stress management and still have residual inflammatory or oxidative burden their labs can't explain
• Patients willing to measure - get a baseline panel before the first session, track markers after each session, and use the data to determine whether they are responding

The patients who are not good candidates for this reason: young, healthy people looking for a precautionary shortcut, or anyone unwilling to do the baseline lab work that tells us whether the intervention is moving anything. TPE without measurement is an expensive guess. With measurement, it becomes a tracked clinical intervention.

What We Do at Liondale

Before a patient's first session, we run a baseline lab panel covering CRP, IL-6, fibrinogen, metabolic markers, and lipids. Where clinically relevant, we include toxin burden assessments. That baseline is what we measure your response against.

TPE at Liondale is performed under Dr. Bissoon's direct oversight, with a trained apheresis nurse. Two to three hours per session. Post-treatment labs run after each session to track what changed. If the inflammatory markers are not moving, we discuss why and whether protocol adjustment is warranted. If they are moving, we have data confirming it.

If microplastics-specific testing becomes clinically standardized and accessible, we will add it to our panel. Currently, validated clinical microplastic testing for individual patients is not yet available at scale. But the markers we do track - inflammatory burden, oxidative stress indicators, metabolic health - are among the downstream effects that microplastic accumulation is hypothesized to worsen. Changes in those markers are useful clinical signals. They are not proof that microplastics specifically were reduced, so we discuss them as indirect indicators, not confirmation.

We are a Circulate Health partner, which means our TPE protocols align with the clinical methodology used in the 2025 Buck Institute trial.

The patients who come to us with this concern typically describe: ongoing fatigue that hasn't responded to clean eating or better sleep, persistent brain fog, slower recovery from exercise, a general sense that their baseline shifted and they cannot explain why. These are the downstream effects that inflammatory and toxin burden are hypothesized to produce. Whether microplastics are contributing specifically is something we cannot yet measure directly - but we can track the markers that would be affected.

In Circulate Health's post-procedure surveys, 90% of patients reported satisfaction with their TPE results. Circulate's research has been covered by the New York Times, Fortune, CNET, the Washington Post, and Axios. Liondale is a Circulate partner.

If you are concerned about microplastic burden or circulating inflammatory load, schedule a consultation. The consultation starts with your history and baseline labs. You can also read more about how we approach TPE at Liondale on our TPE service page.

Safety and Candidacy for TPE in NYC

TPE has been used in hospital medicine for over 50 years. In large retrospective studies, serious adverse reactions occur in roughly 0.12% of procedures. Common temporary side effects include fatigue, mild lightheadedness, tingling from calcium shifts during the session, and bruising at the IV site. These typically resolve within a day.

For elective longevity use - as opposed to FDA-approved indications like myasthenia gravis or Guillain-Barre syndrome - the procedure is self-pay and requires careful pre-treatment screening. Patients with bleeding disorders, clotting factor deficiencies, hemodynamic instability, or albumin allergy are not candidates. Those on anticoagulants or certain immunosuppressants need individualized review. At Liondale, the consultation and baseline labs are the first step before any TPE is scheduled.

Frequently Asked Questions

Can plasma exchange remove microplastics?

It is biologically plausible. Microplastics have been detected in blood, TPE removes and replaces the plasma fraction of blood, so circulating microplastic levels may decrease. But that hypothesis has not been tested in a published human study measuring particle counts before and after TPE. The closest data is Extension Health's 77% BPA reduction - BPA is a plastic-derived chemical, not a particle. The mechanism is similar, but the evidence gap is real. I will not overstate it.

How is this different from a detox cleanse or supplement?

Completely different category. TPE is a regulated medical procedure that has been used in hospital medicine for over 50 years to treat serious autoimmune and neurological conditions. It physically removes and replaces the plasma fraction of your blood under physician supervision. No supplement, cleanse, or chelation protocol operates by that mechanism. The comparison is roughly like comparing a surgical procedure to taking a multivitamin - both may have health value, but they are not the same kind of intervention.

What about the BPA data from Extension Health?

It is relevant and directionally supportive. Extension Health published data showing 77% reduction in BPA (bisphenol A) following TPE in their patients. BPA is an endocrine disruptor that leaches from certain plastics and circulates in blood plasma. TPE removes it. That is the closest published provider dataset suggesting TPE may reduce at least one plastic-derived chemical in circulation. The gap between "BPA reduction" and "microplastic particle reduction" is real - BPA is a small molecule, microplastics are particles - but the mechanism of plasma removal applies to both.

How much does TPE cost?

A single session runs between $6,000 and $15,000 depending on the clinic and protocol. Most patients doing an ongoing program invest $12,000 to $36,000 or more annually. It is not covered by insurance for longevity or anti-aging purposes. For detailed pricing information, see our TPE cost page. For information on the three NYC providers and how to compare them, see our NYC provider guide.

How often would I need treatment for this purpose?

For an initial series, most patients do three to six sessions. After that, maintenance frequency is determined by how your biomarkers are tracking - typically monthly or quarterly. There is no published protocol specifically for microplastics reduction, because that study has not been done. The protocol we use is based on the clinical trial methodology and adjusted based on individual lab response.

What should I bring to a consultation?

Recent bloodwork if you have it - particularly inflammatory markers, metabolic panel, and any toxin or heavy metal testing you have done. A list of your current medications and supplements. And your specific health concerns, including any known exposure history. The consultation is a clinical conversation, not a sales presentation. The more information you bring, the more useful it is.
