Episode Details

For decades, gut health was reduced to yogurt commercials and vague promises from probiotics that barely worked. But what if we’ve been targeting the wrong bugs, using the wrong delivery, and ignoring the true source of chronic inflammation and accelerated aging? 

In this thought-provoking episode, Dave sits down with Hannah Kleinfeld, a leader in microbiome innovation, to expose why most probiotics fail—and how one company’s scientifically validated approach could redefine your gut, brain, immune system, and even your metabolism. 

You’ll learn how dysbiosis may be wrecking your brain without you knowing it, why your probiotic likely died in your stomach acid, and the secret to rebooting your microbiome after antibiotics, GLP-1 drugs, or years of toxic exposure. This isn’t just about digestion—your gut controls your cravings, energy, sleep, mood, and aging trajectory. 

So what’s the one upgrade that can actually reset your gut… for good?
