The Common Mold: Your Guide to Toxicity, Symptoms and Treatments – Dr. Neil Nathan with Dave Asprey – #733

Dave Asprey
What you must know about mold’s toxic effects on your body, brain and environment—and what you can do about it.

In this episode of Bulletproof Radio, my guest is one of the leading experts treating people who have medical problems related to mold exposure.

Over the past 25 years, Neil Nathan, M.D., has become a researcher, complex medical problem-solver and healer—especially of mold toxicity. He treats patients who become too toxic and sensitive, and don’t tolerate usual medical treatments.

“It’s currently thought that there are 10 million people in this country who have some degree of mold toxicity,” Dr. Nathan says. “So, we’re not talking about a rare condition that no one would have any connection to whatsoever. It’s common. And it comes from moldy buildings, which are ubiquitous in this country.”

“Mold symptoms are all over the place,” he says, “because mold toxicity affects inflammation in the body. And every area of the body can be inflamed by mold toxicity.”

There’s a basic biology to all mold dysfunction, explains Dr. Nathan. “Mold toxin enters the cells and begins to interfere with certain types of metabolism. That type of interference affects all parts of the body, including the brain and brain chemistry.”

Dr. Nathan has been practicing medicine for close to 50 years. He’s board certified in Family Practice and Pain Management and currently has a medical practice in Northern California. He has been working to bring an awareness that mold toxicity is a major contributing factor for patients with chronic illness.

In our conversation, we talk about mold’s effect on people, what doctors are getting wrong, and promising new treatments.

“Mold toxicity is something we can diagnose, and we can treat,” Dr. Nathan says. “So if you have yourself, a loved one, a friend, a neighbor, and they’re suffering with a host of conditions and their doctors are scratching their heads and they don’t know what they can do about it—the implication being it’s in your head, but it’s not—tell them about mold toxicity, because it is common and it’s curable.”
