What a Functional Medicine Doctor Wants You to Know About Mold and Mercury Detox

When conversations about detox hit social media, they tend to swing to extremes—either everything is toxic, or nothing is worth worrying about. 

On a recent Ask Me Anything episode ofThe Art of Being Well, Dr. Will Cole and his clinical team field listener questions on topics ranging from dental health to supplements and environmental toxins. But one concern clearly stood out: mold. As conversations about “toxic burden” continue to flood social media, mold exposure has become a growing source of anxiety, leaving many people unsure of what actually matters and what’s just noise.

Mold exposure is about your total load, not just one building.

“Mold is everywhere,” Cole explains, which means exposure alone isn’t the issue. What actually matters is how much mold you’re around, how often, and how your body handles it.

Genetics, immune response, gut health, and overall stress levels all influence whether mold becomes a problem or stays manageable. “We have to look at the bioindividuality here,” he says, pointing to the interplay between genetics, epigenetics, and the environment. For some people, brief exposure may barely register. For others, even moderate levels can trigger symptoms like allergies, migraines, fatigue, brain fog, or histamine reactions.

Why proper testing matters more than guesswork

Mold exposure is often dismissed based on assumption rather than data. Many people believe they’re safe because they don’t see visible mold or notice a smell. But Cole pushes back hard: “Just because you can’t smell it and see it doesn’t mean it doesn’t exist.”

The team stresses that testing needs to be intentional. A quick air sample in a foyer or living room isn’t enough. Instead, testing should focus on where people spend the most time—especially bedrooms and HVAC systems. “You spend a third of your life sleeping in your bedroom,” Cole notes, making it one of the most important areas to assess. 

The team shares cases where mold was found behind walls, near windows, or inside ventilation systems—places no one would think to check without proper testing. In several examples, people were living in newer or visually “clean” homes while ongoing exposure kept their labs from improving.

Detox support can help, but panic makes it worse

When it comes to supporting the body through mold exposure, tools like binders and glutathione can be useful, especially for people who can’t immediately remove themselves from an exposure. But Cole stresses that detox only works when it’s paired with perspective. He’s especially cautious about fear-driven responses, noting that sometimes, obsessing over every possible toxin can overload the nervous system in ways that mirror the physical stress people are trying to avoid.

Rather than chasing perfection, the team focuses on practicality—reducing exposure where possible, supporting detox pathways, and accepting what can’t immediately be changed. “Sometimes the stress and anxiety is worse than the actual mold exposure,” he says, reminding listeners that hypervigilance can add to the body’s burden rather than reduce it.

Mercury detox starts with safe removal, not shortcuts

When the conversation shifts to mercury detox, Cole emphasizes that the most important step is how mercury exposure is handled in the first place. Specifically, the team addresses mercury amalgam (silver) fillings and warns against rushing into removal without proper safeguards.

“It’s safer for most people to keep that amalgam silver filling, mercury filling in your mouth unless you’re going to remove it safely,” Cole states. Improper removal can increase mercury exposure rather than reduce it, especially if vapor is inhaled or swallowed during the process.

Cole consistently recommends working with a trained biological dentist who follows SMART (safe mercury amalgam removal technique) protocols. These methods use protective barriers, high-volume suction, and filtration to limit exposure during removal. Once the source is addressed safely, detox support can actually do its job.

But, as with mold, Cole urges listeners not to turn mercury detox into a fear-based project. Supporting detox is about helping the body clear stressors efficiently—not assuming damage or chasing aggressive interventions without context.
