Clinical Observations

Does Any of This Sound Like You?

Treatment-Resistant Inflammation

  • Autoimmune flares that won’t quit — no matter what you try
  • Chronic fatigue that robs you of the life you used to have
  • Brain fog so thick you can’t think clearly or make decisions
  • Joint pain that has quietly taken over your daily movement
  • Skin conditions that cycle through flares and false recoveries
  • Symptoms that return the moment you stop managing them

You’ve Tried Everything — and Failed

  • Seen multiple specialists — left with more prescriptions, fewer answers
  • Medications that mask symptoms while the root cause continues untouched
  • Side effects that became their own problem to manage
  • Dismissed with “your labs are normal” while your body says otherwise
  • Told to simply “manage your condition for life”
  • Starting to lose hope that real healing is even possible

You’ve Done the Gut Work — Still Sick

  • Cleaned up your diet — still inflamed
  • Healed your gut lining — symptoms persist
  • Taken every supplement — no lasting change
  • Completed detox protocols — still exhausted
  • The problem runs deeper than digestion alone

Here’s what most doctors won’t tell you:

Sometimes the inflammatory triggers keeping you sick aren’t hiding in your gut, your food, or your environment. They’re circulating in your bloodstream and your body simply cannot clear them on its own.

That’s exactly what Therapeutic Plasma Exchange was designed to address.

Medical-Grade Extraction

A Sophisticated Filter For Your Bloodstream

Think of your blood as a river. In autoimmune disease, chronic systemic inflammation, and accelerated biological aging, that river becomes polluted carrying antibodies attacking your own tissues, inflammatory cytokines driving widespread damage, and accumulated biological waste your body cannot clear alone.

No medication can clean that river. Therapeutic Plasma Exchange can.

During the procedure, your blood passes through a specialized medical device that separates your plasma (the liquid component carrying the harmful substances) from your healthy blood cells. The old plasma is discarded. Your blood cells are then recombined with fresh albumin solution and returned to your body.

At The Real Gut Doctor, we enhance this clinically proven, hospital-grade procedure with our proprietary RPRP® (Regenerative Plasma Renewal Protocol) — a personalized regenerative medicine system built around your specific inflammatory profile, diagnosis, and healing goals.

“TPE physically removes the contaminated portion of your plasma and replaces it with a fresh, medical-grade solution taking out the substances that are actively keeping you sick, at the source.”

— Dr. Jeffrey C.G. Mark, M.D.
Clinical Application

How The Procedure Works

01

Blood Draw

Blood is gently drawn from your arm through a small, standard needle no surgery required.

02

Plasma Separation

A specialized apheresis device separates your plasma from your healthy blood cells.

03

Plasma Removal

The old plasma containing inflammatory antibodies, cytokines, and toxins is permanently removed and discarded.

04

Clean Return

Your blood cells are recombined with fresh, medical-grade albumin solution and returned to your body.

05

Personalized RPRP®

Immediately following your exchange, your customized Regenerative Plasma Renewal Protocol is applied optimizing your body’s healing and regenerative response.

Comparative Efficacy

Why TPE Works When Other Treatments Don’t

Approach Standard Protocol TPE + RPRP®
Methodology Suppress symptoms Remove root cause
Mechanism Medication / lifestyle Physical plasma filtration
Evidence Variable FDA-cleared, hospital use
Personalization Generic protocols Custom biological profiling
Post-Care None RPRP® regenerative system
Measurability Subjective Lab-verified reductions

This isn’t another treatment that manages your symptoms.
TPE + RPRP® gives your body the clean slate it needs to finally heal.

Clinical Outcomes

Post-Exchange Restoration

Mental Clarity

As neuroinflammation decreases, patients report dramatic improvements in brain fog and cognitive performance.

Restored Energy

When your immune system stops fighting a constant burden, your energy returns to you fully.

Reduced Flares

Measurable reductions in autoimmune flare frequency across Hashimoto’s, Rheumatoid Arthritis, and Lupus.

Pain Relief

Clearing systemic inflammatory load translates to real reductions in joint and whole-body pain.

Deep Sleep

As the nervous system calms, sleep architecture improves and mood stabilizes.

Real Data

Progress tracked via comprehensive testing showing lab-verified reductions in CRP, ESR, and autoantibodies.

The RPRP® Precision Difference

No two protocols are identical. Dr. Mark designs your post-exchange regenerative treatment around your specific diagnosis, inflammatory profile, and long-term health objectives. It’s not just feeling better—it’s getting your life back securely.

This Isn’t Just Feeling Better. It’s Getting Your Life Back.

Our patients don’t only report fewer symptoms. They report returning to who they were—the energy to pursue what they love, the clarity to lead, and the vitality to live fully rather than just manage illness.

Advanced Therapy Stack

Beyond TPE + RPRP®, Dr. Mark offers a comprehensive suite of advanced regenerative treatments, meaning your care is systematically layered across multiple biological modalities:

EBOO Ozonation PEMF Therapy AWT Wave PRP Plasma Peptides Signaling Exosome Repair

While most doctors respond to treatment-resistant inflammation by adding another medication, Dr. Mark responded by asking a different question: What if we removed what’s keeping them sick, instead of just suppressing how it feels?

That question led to the development of RPRP®.

“When conventional medicine tells you to ‘just manage your symptoms,’ I see an opportunity to remove the very substances causing those symptoms. TPE isn’t suppression, it’s elimination. We’re physically taking the inflammatory triggers out of your body.”

— Dr. Jeffrey C.G. Mark, M.D.
Clinical Innovation

The Origin of RPRP®

Dr. Mark and Dr. Frances Mark, Pharm.D. developed the protocol because standard TPE stops at the mechanical exchange itself.

RPRP® immediately applies a personalized regenerative signal post-exchange to accelerate immune stabilization—closing the gap standard hospitals overlook.

Every RPRP® protocol is customized. No two patients receive the same plan.

Clinical Answers

Frequently Asked Questions

Is Therapeutic Plasma Exchange safe? +

Yes. TPE is a well-established, FDA-cleared medical procedure performed safely in hospital and clinical settings for decades. At The Real Gut Doctor, every session is administered by our specialized clinical team under the direct supervision of Dr. Mark.

Who is a good candidate for RPRP®? +

RPRP® is most appropriate for adults who have not achieved satisfactory results through conventional treatments — including those with autoimmune conditions (Hashimoto’s, RA, Lupus, MS), lab-confirmed chronic systemic inflammation, chronic fatigue or brain fog, and adults over 40 pursuing biological age optimization or peak performance.

How long does a session take? +

A typical RPRP® session takes between 2 and 3 hours, depending on the volume of plasma exchanged and the personalized post-exchange protocol applied.

How many sessions will I need? +

This is determined individually. Before your first session, you will complete a comprehensive medical intake. Dr. Mark will review your full history, lab work, and medications to design a multi-session protocol tailored to your condition.

Is TPE covered by insurance? +

TPE for standard FDA-approved medical indications may carry some insurance coverage. The RPRP® regenerative protocol is typically a self-pay service. Our team will help clarify your coverage during your consultation.

Does TPE help with aging and longevity? +

Yes. Emerging longevity research indicates that replacing older, cytokine-rich plasma with fresh albumin solution dilutes pro-aging factors and creates a more favorable environment for cellular repair. Many of our RPRP® patients pursue the protocol specifically for biological age optimization.
