Should I Detox With Mast Cell Activation Syndrome? Why Stability Comes First, with Dr. Bruce Hoffman (Part 2)
Updated: 4 hours ago
This is Part 2 of a two-part conversation. Part 1 is here: Why Am I Reacting to Everything? How Total Load Sets Off the Mast Cells.
Not at first. With mast cell activation syndrome, Dr. Bruce Hoffman held off on binders, chelation and antimicrobials for the first three to six months and stabilized the body first: safety and support, natural rhythms, self-regulation, POTS, and then the mast cells themselves, often with medication.
When the body reacts to more and more, the instinct is to find every cause and get rid of it. A mycotoxin test comes back positive, and the next step is a binder. A metals test comes back high, and the next step is chelation.
For a body that is already reacting to everything, that starting point can make things worse. The question this episode asks is a different one: if your body is reacting to everything, where do you actually start?
Dr. Bruce Hoffman, MSc, MBChB, FAARM, IFMCP, practiced integrative and functional medicine in Calgary for 30 years and directed the Hoffman Centre for Integrative Medicine. He treated the most complex patients: mold illness, mast cell activation, autoimmunity and Lyme disease. He is a co-author of the global Consensus-2 paper on diagnosing mast cell activation syndrome.
Dr. Hoffman did not start with detox for his most reactive patients. He started with safety and a group where people were seen and heard, then circadian biology and time outdoors, then self-regulation, then POTS, then mast cell stabilizing medication. He held off on binders, chelation and antimicrobials for the first three to six months, whatever the labs said, because a body in a spiral has to stabilize before it can tolerate them.
HOW DO YOU STABILIZE MAST CELLS?
Dr. Hoffman found that four steps, in sequence, changed outcomes for his most reactive patients: the health cycle principles, self-regulation, POTS, and then the mast cells themselves.
"I never approached the toxic load until I've got them stabilized in the health cycle principles, self-regulation, POTS, and mast cells," he says. After those came diet, then hormones, then cell membrane stability. Toxins, mold and Lyme came last, and he did not touch them for the first three months unless there was something acute, such as acute Lyme.
Dr. Aimie puts it plainly: "But for someone in a spiral, stabilization is the first step."
WHY DOES SAFETY COME FIRST FOR A BODY THAT REACTS TO EVERYTHING?
Because many of these patients arrive in dorsal vagal shutdown, and safety is what moves them out of it.
Dr. Aimie opens the conversation with the chronic functional freeze: living with a sense of danger for so long that it becomes normal, pushing through each day under a heaviness, not wanting the day to start. That internal state keeps the loop between the mast cells and the nervous system going.
Dr. Hoffman saw it in patients who came to his Calgary clinic "shutdown, dorsal vagal collapse and shutdown, dissociated, reactive." He found that he could not approach it at the level of the problem. What helped most was a group, his nurses and his neurofeedback team, and a place where patients could communicate, exchange what they knew and be seen and heard. Many had lost trust in their own bodies and in the medical system.
Chronic functional freeze: a long-term shutdown state in which a person keeps functioning and pushing through, while the body stays in a sense of danger underneath.
WHAT ARE THE HEALTH CYCLE PRINCIPLES?
They are the basics of natural living that Dr. Hoffman borrowed from Dr. Robert Naviaux's model of the healing cycle: circadian biology, grounding, sunlight, and in some cases relocation.
Dr. Naviaux's diagram lays out the stages a cell moves through as it recovers from the cell danger response. Dr. Hoffman tells patients to put it on the fridge. Practicing the health cycle principles helped them stop over-identifying with their collapse and with a long list of pathologies.
At the end of his practice, when the UVB index in Calgary dropped below 1 or 2, he sent many patients south to Mexico, Costa Rica or El Salvador to get back into daylight, early nights and time outdoors. He found that more effective than the functional medicine work, which he still did.
Health cycle: Dr. Robert Naviaux's model of the stages a cell moves through as it heals after the cell danger response, and the conditions that let it complete them.
WHERE DO SELF-REGULATION AND POTS FIT?
Self-regulation came second, and POTS came third. Without self-regulation, Dr. Hoffman found, patients stayed upregulated and kept spinning out, and teaching it was "very, very effective in calming down mast cell activation."
POTS and dysautonomia had to be diagnosed and treated next. "If we didn't treat POTS first up front, you couldn't get you couldn't get anywhere," he says.
WHICH MEDICATIONS CALM MAST CELLS?
H1 and H2 blockers, cromolyn, leukotriene blockers and ketotifen, each acting on different mast cell chemicals. They come fourth in his sequence, though for someone in a spiral he started them early.
H1 and H2 blockers. Two kinds of antihistamine. H1 blockers are the kind many people take for allergies; H2 blockers are often used for stomach acid. Dr. Hoffman finds that the pair calms more than histamine.
Cromolyn. Keeps mast cells in the gut from releasing their chemicals. He uses it for gut symptoms and food sensitivities.
Leukotriene blockers. He used montelukast (Singulair) particularly for gut and lung symptoms. Montelukast carries an FDA boxed warning for serious mental health side effects, so it is a decision for a prescribing physician.
Ketotifen. His go-to first-generation H1 blocker when sleep is a problem, compounded.
He compounds everything for reactive patients because of reactions to fillers and dyes, which Part 1 covers.
CAN SUPPLEMENTS STABILIZE MAST CELLS?
They help, but in Dr. Hoffman's experience very few people get out of a spiral with supplements alone. "I found the medication route far more effective than supplements," he says.
He used luteolin, quercetin, black cumin seed and non-citrus vitamin C. For someone spiraling, he used IV and oral mast cell medications first. "I had to use heavy guns in the beginning and then get them off the meds as soon as possible." Many people could come off after a year or two.
SHOULD I START WITH BINDERS OR A DETOX?
Not at the start, in Dr. Hoffman's view. He does use them later. What he objects to is going straight to binders, herbals or antibiotics for someone who is not yet stable.
He spent the last five years of his practice seeing very sick patients arrive with a urine mycotoxin test or a Lyme panel, already on binders or antibiotics, with no mention of safety, self-regulation or mast cells. "It's not that you don't do those things you do," he says, "but not when you just met the person half an hour."
He singles out cholestyramine, a binder often used in mold protocols. In his clinical opinion it strips lipids the cell membranes need. It binds bile acids and can lower fat-soluble vitamins over time, which is one reason timing matters.
His alternative is a relationship first. "Doctor as healer, not as hero," built on mutual trust, with a toolkit wide enough to work at every layer.
HERXHEIMER OR MAST CELL REACTION: HOW CAN I TELL?
By timing, by the kind of symptoms, and by whether mast cell treatment helps.
A Herxheimer reaction follows antimicrobial treatment, as organisms die off, and brings fever, chills and headache. Dr. Hoffman describes it following within a day or two; the medical literature describes onset within 24 hours, often within hours. A mast cell reaction tends to bring itching, hives, rashes and asthma, and in his experience comes 30 to 120 minutes after an exposure. The difference that settles it is response: mast cell reactions calm with mast cell stabilization.
A fast, severe reaction with throat swelling or trouble breathing is an emergency whatever its cause.
Herxheimer reaction: a short-term flare of fever, chills and inflammation after antimicrobial treatment, caused by the body's response to organisms dying off.
WHY IS MAST CELL ACTIVATION SO HARD TO TEST FOR?
Because the samples are fragile and the most familiar test is often normal.
Mast cell labs have to stay cold, be spun in a chilled centrifuge and be shipped on dry ice. Handled any other way, they can come back normal when they are not. Tryptase, often the first test a doctor orders, is "very seldom positive" in mast cell activation in Dr. Hoffman's experience.
The earlier consensus criteria lean on tryptase; the Consensus-2 paper he co-authored takes a broader view based on symptoms, response to treatment and labs together. Allergists and immunologists continue to debate the two approaches.
WHAT IS A THERAPEUTIC TRIAL?
A trial of a medication or supplement that calms mast cells, to see whether the symptoms respond.
"So if a person has a flare you try and catch the labs and then you try mast cell stabilizing meds. And if they stabilize you've got your diagnosis," Dr. Hoffman says. Dr. Aimie adds that a result either way is useful. If symptoms do not calm down, that points to something other than mast cells, and that is what to look for next. "So a therapeutic trial helps us be more precise with knowing what are we targeting, rather than throwing everything at the problem, but not really knowing what the problem is yet."
WHEN IS IT TIME TO ADDRESS HEAVY METALS AND TOXINS?
After the first three to six months. "Do not go near a patient in the first 3 to 6 months with chelation," Dr. Hoffman says, even with a high red cell mercury result, because chelating agents also strip cell membranes.
What he did early, alongside the sequence, was membrane support: oral and IV phosphatidylcholine and glutathione, sauna, nutrition, dietary change and self-regulation. He describes a detailed mitochondrial and toxin panel, from a German lab that no longer offers it, going from mostly abnormal to mostly normal within six months in the large majority of his patients. Adding circadian biology improved results again. These are his clinical observations, not a published trial.
WHAT DOES DR. HOFFMAN SEE AS THE FUTURE OF MEDICINE?
Talking to the healthy side of the patient, and returning people to natural rhythms.
He is inspired by a move away from treating patients as broken and toward a roadmap from despair to hope. At its center is "taking us out of our zoo-like existence and making sure we are rewilding back into natural felt sensations like the elephants and the trees and the sun."
Dr. Aimie turns it into a first step for today: "Just spend a little more time outside today. Spend a little more time being in the wild. Find that wild side of you again."
Key Takeaways
For a body that reacts to everything, the order of care matters as much as the care itself.
Dr. Hoffman's sequence: health cycle principles, self-regulation, POTS, mast cells, then diet, hormones and cell membranes, then toxins, mold and Lyme.
Safety came first: a group, a team and a place to be seen and heard helped patients out of dorsal vagal shutdown.
Circadian biology, sunlight and time outdoors were among the most effective steps he used.
Calming mast cells directly often means H1 and H2 blockers, cromolyn and leukotriene blockers, prescribed and compounded.
In his experience, supplements help but rarely pull someone out of a spiral on their own.
He held off on binders, chelation and antimicrobials for the first three to six months.
Herxheimer and mast cell reactions differ in timing, symptoms and response to mast cell treatment.
Mast cell labs are fragile, and tryptase is often normal, so a therapeutic trial can help clarify the picture.
A relationship built on trust, doctor as healer rather than hero, is part of treatment.

Episode Takeaway
When the body is reacting to everything, the instinct is to find every cause and remove it. A test comes back with mycotoxins, so we reach for a binder. A metals panel comes back high, so we reach for chelation. It feels like action, and it feels like progress.
I wanted this conversation because I see what happens when people start there. The body that is already reacting to everything gets one more thing to react to. What looked like the solution becomes part of the problem.
Dr. Hoffman spent his career with the most complex patients, and what he offers here is an order. First, safety. His patients came to him in shutdown, having lost trust in their bodies and in medicine. What moved them first was a place to be seen and heard, a team around them, and a group of people who understood. Then the basics of natural living: daylight, darkness at night, time outdoors, the rhythms our biology expects. Then self-regulation. Then POTS. Then calming the mast cells directly, with medication when that is what it takes. Only after all of that did he turn to the toxins, the mold and the Lyme.
This is the part I most want you to hold. Those later treatments have their place, and their place is later. A body in a spiral does not have the capacity to handle them yet, and pushing them early can deepen the very reactivity we are trying to calm.
It also changes how we think about what is happening. So many of the people I work with live in a chronic functional freeze. They push through every day under a heaviness. They wake up wishing the day was not starting. That internal state keeps the loop going between the nervous system and the mast cells, and no binder reaches it.
I also loved Dr. Hoffman's point about the therapeutic trial. When the labs are hard to get right and the most familiar test is often normal, trying a treatment that calms the mast cells tells us something either way. If the symptoms settle, we know where to focus. If they do not, that is useful too, because now we know to look somewhere else. That is precision, and it is kinder to the body than throwing everything at it at once.
For today, start small. Spend a little more time outside. Let your body feel the sun and the ground. That is part of the work too.
In the Biology of Trauma® framework, the work follows an order: safety, then support, then expansion. What Dr. Hoffman found with his patients follows the same sequence. Chapter 12 of the book lays out that biology lens step by step.
If you recognize yourself in the spiral he describes, stabilization is where you start, and it starts with your internal state and your nervous system. The Foundational Journey is the clear path for that stabilization. It builds the safety and capacity everything else depends on, so that when it is time for the next layer, your body can hold it.
Frequently Asked Questions
How do you stabilize mast cells?
Work in order. Dr. Bruce Hoffman starts with safety, circadian biology and time outdoors, then self-regulation, then treating POTS, then mast cell medications such as H1 and H2 blockers and cromolyn. Binders, chelation and treatment for mold, Lyme and metals come later.
Should I do a mold or heavy metal detox first if I have mast cell activation?
Dr. Hoffman does not start there. He holds off on binders, chelation and antimicrobials for the first three to six months while the person stabilizes, unless something acute needs treatment.
Do supplements work for mast cell activation?
They can help, and he uses luteolin, quercetin, black cumin seed and non-citrus vitamin C. In his experience, very few people get out of a spiral on supplements alone, so he uses medication first and tapers when possible.
How can I tell a Herxheimer reaction from a mast cell reaction?
A Herxheimer reaction follows antimicrobial treatment and brings fever, chills and headache. A mast cell reaction brings itching, hives, rashes or asthma soon after an exposure and calms with mast cell stabilization.
Can you have mast cell activation syndrome with a normal tryptase?
Yes. Dr. Hoffman finds tryptase very seldom positive in mast cell activation, and mast cell labs can read normal if the sample is not kept cold. The Consensus-2 approach looks at symptoms, response to treatment and labs together.
What is a therapeutic trial for mast cells?
A trial of a mast cell stabilizing treatment to see whether symptoms respond. If they do, that points to mast cells. If they do not, it points elsewhere.
Why does POTS need treatment before mast cells?
In Dr. Hoffman's sequence, untreated POTS and dysautonomia kept patients from making progress with anything else, so he diagnosed and treated them before stabilizing the mast cells.
