When Dave Asprey came on my show to talk about mold toxicity, I knew it would resonate. What I didn't anticipate was just how deeply it would land.
The episode has now surpassed 800,000 views on YouTube, and with Dave's 1.3 million Instagram followers, the response has been overwhelming. That's because mold toxicity isn't fringe. It's misunderstood, underdiagnosed, and quietly driving chronic inflammation, neurological dysfunction, hormonal disruption, and immune dysregulation in millions of people.
This blog distills our long-form conversation into a clear, actionable narrative—grounded in Dave's personal journey, emerging science, and what I see every day in clinical practice.
Dave Asprey's Mold Story: A Lifetime in the Making
Dave grew up in a flooded basement in the 1970s and 80s—long before mold toxicity was understood. As a child and young adult, he experienced:
- Chronic asthma and arthritis by age 14
- OCD, oppositional defiant disorder, and Asperger-like symptoms
- Recurrent strep throat requiring 15 years of antibiotics
- Severe weight gain (over 300 lbs by his early 20s)
- Hormonal collapse (testosterone levels lower than his mother's)
- Chronic fatigue, fibromyalgia, and cognitive dysfunction
By age 30, Dave had nearly every diagnosis except the correct one.
The missing piece? Mold toxicity and mycotoxins.
Mold doesn't just live on walls. It produces mycotoxins—tiny, biologically active molecules that disrupt mitochondria, hormones, immune signaling, and the nervous system. These toxins are small enough to bypass many of the body's defenses, yet potent enough to derail energy production at the cellular level.
Mold Is a Mitochondrial Toxin (And That Changes Everything)
One of the most important takeaways from our conversation is this:
Most mycotoxins directly poison mitochondria.
Mitochondria are ancient bacteria. Mold produces compounds that function like antibiotics. When you breathe or ingest them, you're essentially exposing your mitochondria to a biochemical attack.
This explains why mold toxicity presents as:
- Brain fog
- Crushing fatigue
- Exercise intolerance
- Hormonal imbalance
- Mood instability and rage
- Dysautonomia and low blood pressure
Dave described it perfectly: "Everything in life feels like walking uphill."
The Symptoms That Are Commonly Missed
Mold toxicity is often misdiagnosed because symptoms are diffuse and systemic. Red flags include:
- Unexplained weight gain or estrogen dominance
- Autoimmune-like symptoms without clear labs
- Chronic UTIs or interstitial cystitis
- Frequent bruising or balance issues
- Nightmares or vivid, threatening dreams
- Sudden rage, anxiety, or emotional volatility
- Chemical sensitivities or "multiple chemical sensitivity"
Many patients—especially women—know something is wrong long before labs validate it.
That intuition matters.

Air Quality: The Fastest Win No One Talks About
If there's one actionable step Dave and I agree on immediately, it's this:
Fix your air first.
You breathe 30+ pounds of air per day. Mycotoxins are often bound to dust and easily inhaled.
Start here:
- High-quality air purifier in the bedroom (non-negotiable)
- Control bathroom humidity (exhaust fans, continuous airflow)
- Vacuum and dust regularly
- Be mindful of cars—AC systems frequently harbor mold
Most people filter their water obsessively and ignore the air they breathe all night.
Coffee, Food, and Hidden Mycotoxins
One of the more eye-opening parts of our discussion centered on ochratoxin A, a common mycotoxin found in:
- Coffee
- Wine
- Beer
- Grains
- Nuts
Unlike Europe, the U.S. has no regulatory limits on ochratoxin in coffee. Moldy beans rejected overseas often end up here.
Signs your coffee may be the problem:
- Jittery + exhausted feeling
- Urgent urination without a full bladder
- Brain fog an hour or two later
This is why Dave stopped drinking conventional coffee for years—and why food quality matters as much as air quality when addressing mold burden.
Oxalates, Mold, and Chronic Pain Syndromes
Another underappreciated connection is between mold and oxalates—microscopic calcium crystals that behave like shards of glass in tissues.
Oxalates contribute to:
- Joint pain
- Brain fog
- Vulvodynia
- Interstitial cystitis
- Kidney and bladder irritation
Mold exposure can increase endogenous oxalate production, compounding dietary sources from spinach, nuts, almonds, and grains.
Why "Just Detoxing" Isn't Enough
One of the most important clinical insights Dave shared is that mold recovery has phases:
- Remove exposure (environment matters)
- Support energy production (mitochondria first)
- Bind and eliminate toxins
- Address internal fungal burden when present
- Retrain the nervous system
Many people get stuck because they attempt detox while their nervous system is in constant fight-or-flight. When energy is depleted, detox makes people worse—not better.
Mold, Trauma, and the Nervous System
Here's the part most conversations miss.
Mold exposure can create a PTSD-like response in the nervous system. Even after toxins are addressed, the body may remain hypervigilant—reacting before the conscious mind can intervene.
Dave's new book, Heavily Meditated, explores this deeply, introducing concepts like:
- Nervous system re-patterning
- Dopamine restoration through brief stress exposure (BICEP)
- Forgiveness as a biological—not psychological—process
Healing from mold isn't just biochemical. It's neurological.
What I Tell My Patients Every Day
If you're overwhelmed, here's where to start—today:
- Improve air quality
- Improve food quality
- Improve water quality
- Protect sleep
These four levers alone can dramatically reduce inflammatory load and restore resilience.
And if you suspect mold—but no one believes you—trust your intuition. As Dave said:
"You're not crazy. You're actually plugged in."
