1. What Is the Base Spike Detox?

The Base Spike Detox is a clinical protocol developed by Dr. Peter McCullough — internist, cardiologist, and one of the most-published physicians in the United States — designed to help the body degrade and clear persistent SARS-CoV-2 spike protein.

In a widely shared post on X (formerly Twitter), Dr. McCullough explained the rationale:

"Base Spike Detox is what I am currently using in my practice for those who have had COVID-19 multiple times, one or more of the COVID-19 vaccines, or both, and believe persistent SARS-CoV-2 Spike protein could be causing problems in their body. I have arrived, based on the emerging scientific literature and my clinical observation, that three OTC products are essential as a triple base combination." — Dr. Peter McCullough, MD, MPH

The protocol targets a specific problem: spike protein — introduced by either natural SARS-CoV-2 infection or mRNA vaccination — appears to persist in some individuals, potentially driving ongoing inflammation, clotting abnormalities, and immune dysregulation associated with long COVID and post-vaccine syndromes.

The three core supplements are all available over the counter, making this a self-initiation protocol that patients can begin while arranging a physician consultation. However, physician oversight is strongly recommended.

2. Protocol: Ingredients, Doses & Timing

Base Spike Detox — Core Triple Combination

All three ingredients are over-the-counter. Minimum duration: 3 months. See Section 3 for full duration guidance.

Nattokinase2,000 FU (100 mg) — twice daily ⚠ Take on an empty stomach. Do not take with anticoagulants without physician guidance.
2

Bromelain500 mg — once daily ⚠ Take on an empty stomach. Avoid if allergic to pineapple or latex.
3

Nano / Liposomal Curcumin500 mg — twice daily ✓ Take with food. Nano or liposomal form required for adequate absorption.

Quick-Reference Dosing Table

Nattokinase: 2000 FU (100 mg) twice daily (on an empty stomach).
Bromelain: 500 mg once daily (on an empty stomach).
Curcumin (preferably nano or liposomal form for better absorption): 500 mg twice daily (with food).

Ready-Made OptionThe Wellness Company's Base Spike Detox Trio combines all three ingredients at these exact doses. It is the first spike detox formulation to appear in the US medical literature and was developed in collaboration with Dr. McCullough.

3. How Long Should You Take the Base Spike Detox?

This is the most frequently asked question about the protocol. Dr. McCullough's guidance, drawn from his 2023 Cureus publication and subsequent clinical updates, is as follows:

Minimum duration: 3 months
Typical duration: 6–12 months, depending on symptom burden and laboratory response
Severe or persistent cases: More than one year may be required
Ongoing use: If well tolerated, the protocol can be continued indefinitely to prevent recurrence from reinfection or re-exposure

"Don't expect instant results, be patient. Three months is a minimum duration, and some require more than a year." — Dr. Peter McCullough

Progress can be tracked objectively using spike protein antibody testing (see Section 6). Symptom improvement is the primary clinical endpoint when testing is unavailable.

4. The Science Behind Each Ingredient

Nattokinase: Direct Spike Protein Degradation

Nattokinase is a serine protease derived from fermented soybeans (natto). It is best known as a fibrinolytic — an enzyme that breaks down fibrin clots — and has over 250 published studies on PubMed.

In a 2022 study, Tanikawa and colleagues demonstrated that nattokinase degrades the SARS-CoV-2 spike protein in a time- and dose-dependent manner, both in cell lysate preparations (analogous to the environment in a vaccine recipient) and in SARS-CoV-2-infected cells.⁴ This was independently reproduced by Oba and colleagues.

In human pharmacokinetic studies, Kurosawa et al. found that a single oral dose of 2,000 FU significantly elevated D-dimer at six and eight hours post-administration and elevated fibrin/fibrinogen degradation products at four hours — confirming meaningful systemic fibrinolytic activity after oral intake.

Editor's Note on Fact-Checks: We are aware of an AFP fact-check article titled "Experts rubbish Covid vaccine 'detoxification' supplement," which states there is "no evidence that nattokinase dissolves the spike protein of SARS-CoV-2 in the human body." It is important to note that the Tanikawa study cited in that same article is a laboratory study — the standard starting point before larger human trials. We agree nattokinase is not a miracle drug, and further clinical research is needed. More than 250 nattokinase studies are indexed on PubMed. We encourage readers to review the evidence and consult their physician.

Bromelain: Fragment Clearance & Anti-Inflammation

Bromelain is a mixture of proteolytic enzymes derived from pineapple (Ananas comosus). It has well-documented anti-inflammatory, fibrinolytic, and mucolytic properties. In the context of spike protein pathology, bromelain is hypothesized to assist in degrading spike protein fragments that nattokinase leaves behind, while simultaneously reducing the systemic inflammation those fragments provoke.

Bromelain also prolongs prothrombin time, contributing to the protocol's overall anticoagulant effect — which is relevant to its potential benefit in patients with spike-induced microclotting.

Curcumin (Nano/Liposomal): Inflammation Reduction & Immune Modulation

Curcumin, the active polyphenol in turmeric, has potent NF-κB inhibitory and antioxidant properties. Standard curcumin has poor bioavailability; nano- or liposomal formulations are essential to achieve the tissue concentrations needed for meaningful anti-inflammatory effect.

In the context of this protocol, curcumin complements nattokinase and bromelain by addressing the downstream inflammatory cascade triggered by circulating spike protein and its fragments.

Ivermectin: Reversing Spike-Induced Hemagglutination

Former NIH researcher David Scheim, PhD, proposed early in the pandemic that SARS-CoV-2 spike protein acts like a grappling hook, pulling circulating red blood cells (RBCs) into chains and clumps — a process called hemagglutination (HA) — impairing oxygen delivery and contributing to microclotting in the lungs.

Boschi et al.⁶ subsequently demonstrated that ivermectin reverses this effect:

"Ivermectin blocked hemagglutination when added to RBCs prior to spike protein and reversed HA when added afterwards."

Stone et al.⁷ documented a 62% normalization in oxygen saturation within 24 hours of ivermectin-based combination treatment in severe COVID-19 patients — a rate of improvement that, given its speed, points to a direct anti-spike protein mechanism rather than an antiviral effect alone.

5. Add-On Agents: Beyond the Base Combination

Dr. McCullough notes that additional agents can be incorporated based on a clinical evaluation and the specific syndrome present. These are not universally recommended and generally require physician prescription and oversight:

N-acetylcysteine (NAC) for further detoxification.
Ivermectin (prescription) for reversing spike-induced blood clumping.
Others like hydroxychloroquine, low-dose naltrexone, or blood thinners if specific risks (e.g., clotting) are present.

Overlap with FLCCC I-RECOVER ProtocolThe Base Spike Detox shares significant overlap with the FLCCC Alliance's I-RECOVER Post-Vaccine Treatment Protocol, which addresses the broader management of post-vaccine and long-COVID syndromes. For detailed treatment strategies — particularly for complex, multi-system cases — the I-RECOVER protocol is recommended as a complementary reference.

6. How to Monitor Your Progress

Dr. McCullough recommends objective laboratory monitoring to guide treatment duration and assess response:

Spike Protein Antibody Testing

The Labcorp Semi-Quantitative Spike Protein Antibody Test (available in most US states directly through Labcorp's website without a physician order) can establish a baseline level of spike protein antibody and track reductions over time. Several patients have documented marked reductions — for example, Dr. Robert Enzenauer reported his spike antibody falling from 1:25,000 to 1:740 over six months on the protocol.

Healthlabs.com also offers a COVID-19 antibody test that can be ordered online and completed at a local lab.

Symptom Tracking

In the absence of laboratory testing, symptom improvement is the primary marker. Common targets include: resolution of fatigue, brain fog, exercise intolerance, dyspnea, and musculoskeletal pain.

Coagulation Monitoring

Given the significant fibrinolytic and anticoagulant activity of this combination, patients and clinicians should monitor for:

Easy bruising
Nasal mucosal bleeding
Gastrointestinal bleeding symptoms
Prolonged bleeding from minor cuts

These are signals to reduce the dose or temporarily suspend the protocol, with physician guidance.

7. Safety Warnings & Contraindications

🚫 Absolute Contraindications

Active bleeding disorder (e.g., hemophilia)
Pregnancy (without physician direction)
Breastfeeding (without physician direction)
Known soy allergy (nattokinase)
Known pineapple or latex allergy (bromelain)
Children under 18 (without physician direction)

⚠️ Use with Caution / Physician Oversight Required

Concurrent anticoagulants (warfarin, apixaban, rivaroxaban, dabigatran)
Concurrent antiplatelet drugs (aspirin, clopidogrel)
History of GI bleeding or peptic ulcer disease
Women of childbearing potential without contraception
Gastrointestinal intolerance or sensitivity

Using the Protocol with Anticoagulants

This is among the most common patient questions. Dr. McCullough addressed it directly in 2025:

"As an internist and cardiologist, the answer is yes [it can be used with anticoagulants], but this must be done with doctor's guidance. Nattokinase is an oral thrombolytic. Bromelain is an anticoagulant that prolongs prothrombin time... On anticoagulants? Bring your doctors in the loop." — Dr. Peter McCullough, X/Twitter, 2025

In clinical practice, Dr. McCullough has used full-dose Ultimate Spike Detox alongside apixaban, rivaroxaban, dabigatran, and warfarin in patients with thrombotic complications. The primary safety signal is bleeding — excessive mucosal bleeding or unusual bruising indicates a dose reduction of either the detox supplement or the anticoagulant, per physician judgment.

8. Clinical Observations & Patient Stories

Note on Anecdotal ReportsThe following accounts are patient- and physician-reported observations, not peer-reviewed clinical outcomes. They are included as illustrative examples consistent with the proposed mechanism of action. Individual results will vary. Large randomized controlled trials are not yet available.

Dr. Robert W. Enzenauer, MD, MPH (Physician, September 2024)

"I am a physician who got Pfizer [vaccine in] 2020, 2021 and 2021 to keep working at a hospital in Colorado. I am happy to report: March 2024 spike antibody 1:25,000. Using the McCullough protocol now six months, my spike antibody [is] down to 1:740 in September 2024. Thank you."— Dr. Robert W. Enzenauer, MD, MPH, via The Focal Points, September 2024

Dr. Bruce Boros, MD (Internist & Cardiologist, Florida Keys)

Dr. Boros, age 75 and unvaccinated, developed symptoms consistent with long-COVID syndrome — loss of mental clarity, cognitive fog, and profound fatigue — that threatened his active medical practice. After discussing the science of the McCullough protocol, he initiated Ultimate Spike Detox from The Wellness Company. Built on a prior regimen that included ivermectin for acute COVID treatment, Dr. Boros reported resolution of his symptoms within weeks, with similar improvements observed in his long-COVID patients.

Dr. McCullough notes that a detoxification protocol should be followed for at least one year to prevent symptom recurrence, which may occur with reinfection or re-exposure. If well tolerated, these products can be continued indefinitely.

Patient: Taste and Smell Restoration (Long COVID, March 2025)

"I had a mild case of COVID in May 2020 and subsequently endured long COVID for 3 years. It affected my taste and smell severely. I followed this protocol for about 2–3 months and am very ecstatic to say my taste and smell are back to normal."— Anonymous patient, blog comment, March 2025

Patient: Leg Swelling Resolution (Vaccine Injury, February 2025)

"I took one shot and my leg swelled up three times its normal size. It didn't go away until I found McCullough's bromelain-based spike detox regimen, and it was gone within a week."— The Human Condition, X/Twitter, February 2025

Patient: Blood Clot in the Eye (Nurse, November 2024)

"I woke up one morning before work and couldn't see out of my left eye [blood clot near optic nerve/retina]. Nothing seemed to work to dissolve it — until I started taking Spike Detox by The Wellness Company. About a week after starting, I noticed vision slightly improving. Vision was completely back to normal — clot dissolved — in about three weeks."— Keith (RN), Substack comment, November 2024

Long COVID: Leg Swelling with Protocol + Ivermectin (September 2025)

"I did not get the vax but I did get COVID at least twice. About 6 weeks [after the second infection] my right knee/leg started swelling... I contacted Dr. Kory's clinic and got on this protocol (which also included ivermectin 0.4 mg/kg). My leg swelling resolved after about 6 weeks."— Anonymous patient, blog comment, September 2025

9. COVID-19 Vaccine Myocarditis Research

Dr. Peter McCullough co-authored a study on vaccine-induced myocarditis that was awarded first place on Preprints.org in the Medicine and Pharmacology category (Cardiac & Cardiovascular Systems) for 2023.

The paper — Autopsy Proven Fatal COVID-19 Vaccine-Induced Myocarditis³ — examined fatal outcomes of myocarditis following COVID-19 vaccination, providing histopathological evidence from autopsy cases. It was subsequently published in the European Journal of Heart Failure.

This body of research forms part of the broader scientific context motivating the development of post-vaccine syndrome management protocols, including the Base Spike Detox.

10. Frequently Asked Questions

What is the McCullough Base Spike Detox Protocol?

It is a regimen developed by Dr. Peter McCullough to help the body degrade and clear persistent SARS-CoV-2 spike protein from either natural infection or vaccination. The core regimen uses three OTC supplements — nattokinase (for direct spike protein degradation), bromelain (for fragment clearance and anti-inflammation), and nano/liposomal curcumin (for inflammation reduction and immune support). Additional prescription agents may be added based on clinical evaluation.

What are the recommended doses, and when do I take each supplement?

Nattokinase: 2,000 FU (100 mg) twice daily — on an empty stomach
Bromelain: 500 mg once daily — on an empty stomach
Curcumin (nano/liposomal): 500 mg twice daily — with food

Taking nattokinase and bromelain on an empty stomach maximizes absorption. Curcumin is fat-soluble and better absorbed with a meal.

How long should I take the Base Spike Detox?

A minimum of 3 months is recommended, with most patients requiring 6–12 months depending on symptom severity, spike protein antibody levels, and whether reinfections occur. Some patients require more than a year. The protocol can be continued indefinitely if well tolerated, to guard against recurrence.

Who may benefit from this protocol?

Individuals who may consider this protocol include those experiencing:

Long COVID symptoms (fatigue, brain fog, dyspnea, musculoskeletal pain)
Post-vaccine syndrome symptoms
Multiple SARS-CoV-2 infections with persistent symptoms
Elevated spike protein antibody levels on laboratory testing

Always discuss with a physician to determine appropriateness for your individual situation.

Can I take this protocol while on blood thinners (Eliquis, Xarelto, warfarin, etc.)?

Yes, but only under physician supervision. Dr. McCullough has used full-dose Ultimate Spike Detox alongside apixaban, rivaroxaban, dabigatran, and warfarin in patients with spike protein-related thrombotic complications. The key risk is bleeding. Monitor for:

Unusual bruising or skin bleeding
Nasal or gum bleeding
GI symptoms suggesting internal bleeding

If these occur, reduce the dose of the detox supplement or the anticoagulant per your doctor's guidance. Do not combine these without telling your physician.

Can I take the protocol if I am on aspirin?

Aspirin is an antiplatelet agent with blood-thinning activity, not a traditional anticoagulant. Because nattokinase and bromelain both have fibrinolytic/anticoagulant effects, combining them with aspirin increases bleeding risk. Physician review is recommended before combining. Some patients who are using aspirin therapeutically (e.g., cardiovascular prevention) may consider whether their aspirin dose can be temporarily adjusted — this must be a physician-guided decision.

Is there an alternative to nattokinase if I can't take it (e.g., soy allergy, low blood pressure)?

Serrapeptase is a proteolytic enzyme sometimes discussed as an alternative fibrinolytic. However, it has not been specifically studied for spike protein degradation in the same manner as nattokinase, and Dr. McCullough has not formally endorsed it as a substitute. If nattokinase is contraindicated for you, consult a physician familiar with this protocol for personalized guidance. The FLCCC's I-RECOVER protocol includes additional agents that may be appropriate alternatives.

Can children take this protocol?

The standard Base Spike Detox protocol is not recommended for children without direct physician supervision. Dosing must be adjusted by weight and age, and the safety profile in pediatric populations has not been formally established. Parents of children with suspected spike protein-related symptoms should consult a physician — ideally one familiar with this protocol, such as those available through The Wellness Company's virtual care platform.

What about pregnancy or breastfeeding?

This protocol is not recommended during pregnancy or breastfeeding without physician direction. Both nattokinase (fibrinolytic activity) and bromelain (potential uterotonic effects at high doses) carry theoretical risks. Women of childbearing potential who are not using contraception should also consult a physician before starting. There is no established pediatric dosing for infants exposed through breast milk.

Can I add ivermectin? What is the dose?

Yes, ivermectin can be added as an adjunct based on clinical evaluation, particularly for patients with respiratory symptoms or suspected hemagglutination-related oxygen impairment. The suggested dose range is 0.2–0.3 mg/kg daily (some long-COVID protocols use up to 0.4 mg/kg). Ivermectin requires a prescription in most countries. The FLCCC I-RECOVER protocol provides detailed guidance on ivermectin use in post-COVID/post-vaccine syndromes.

How do I monitor whether the protocol is working?

Two approaches:

Laboratory: The Labcorp Semi-Quantitative Spike Protein Antibody Test (available directly through Labcorp without a physician order in most US states) can establish a baseline before starting and track reductions over months. Healthlabs.com also offers a COVID-19 antibody test.
Clinical: Symptom improvement — particularly resolution of fatigue, brain fog, dyspnea, and exercise intolerance — is the primary real-world marker.

Dr. McCullough considers laboratory monitoring useful in guiding both the response to treatment and the duration of treatment.

Is there scientific evidence supporting this protocol?

The protocol is supported by:

In vitro evidence: Tanikawa et al. (2022) demonstrated nattokinase degrades SARS-CoV-2 spike protein in cell preparations — replicated independently by Oba et al.
Human pharmacokinetic data: Kurosawa et al. confirmed meaningful systemic fibrinolytic activity after oral nattokinase dosing.
Clinical publication: McCullough et al. (2023, Cureus) describe the clinical rationale and proposed regimen.
Ivermectin mechanism: Boschi et al. and Stone et al. provide mechanistic and clinical support for ivermectin's anti-spike hemagglutination effects.
Clinical observation: Multiple physician reports including documented spike antibody reductions.

What is lacking: Large, randomized placebo-controlled trials — which Dr. McCullough acknowledges are 5 or more years away. The protocol is grounded in the best available evidence for patients who need options now.

Will I experience side effects or a "detox reaction" when starting?

Some patients report temporary symptom flares in the first weeks of the protocol — including fatigue, tingling, or mild GI discomfort. Whether this represents a genuine Herxheimer-type reaction (systemic response to spike protein clearance products) or an adverse response is not established. If symptoms are significant or worsen, pause the protocol and consult a physician. Never push through severe symptoms without medical review.

I never took the vaccine but had COVID. Does this protocol apply to me?

Yes. The protocol is indicated for spike protein persistence from either natural infection or vaccination. SARS-CoV-2 infection itself results in spike protein production, and long COVID is increasingly understood as a consequence of persistent spike protein and its fragments — not solely a vaccine-related phenomenon. Patients with long COVID following natural infection have reported benefit from this protocol.
