The Shocking Reason Your Anxiety, Brain Fog & Bloating May Start in Your Gut

In this episode, Dr. Josh Axe breaks down the science of the gut microbiome — the hidden ecosystem of bacteria, fungi, and microbes that may influence digestion, nutrient absorption, immune health, mood, cravings, inflammation, hormones, and longevity. He explains why your gut is often called your “second brain,” how the gut-brain connection works through the vagus nerve, and why 90% of serotonin is connected to the gut.
