70% of Your Immune System Lives in Your Gut | Dr. Will Bulsiewicz
About this episode
Dr. Will Bulsiewicz reveals a profound connection between your gut and your total well-being: 70% of your immune system resides in your gut lining.
The quiet enemy? Chronic inflammation, which is silently eroding your energy, focus, and long-term health. You aren't just drained from a busy life; you're inflamed because your gut microbiome is compromised. This inflammation triggers a cascade of symptoms that many have come to view as "normal."
What sets this conversation apart is Dr. Will's deeply personal journey. He shares how unresolved trauma, including a decade-long estrangement from his father, sabotaged his health even with a perfect diet.
You will discover the specific foods that fortify your gut barrier and calm the immune system. Crucially, you'll also learn why spiritual healing and processing past wounds might be the critical missing link in your health equation.
This is much more than a guide to better digestion—it's a path to finally feeling truly alive again.
