In this fast-paced 90s explainer we break down science-backed facts: 500 million ENS neurons, 90% of serotonin made in the gut, and how prebiotic fiber fuels microbes that protect your gut lining and calm your brain. Perfect for wellness seekers curious about gut health, mental health, and lifestyle hacks to improve mood and focus.
