Meet Vita —

Ask anything about your body. Get an answer backed by actual peer-reviewed research — with the study, the authors, and the mechanism explained clearly.
Your gut and brain maintain a constant two-way dialogue through the vagus nerve. This isn't metaphorical: your gut produces roughly 90–95% of the body's serotonin — not your brain. The enterochromaffin cells lining your intestinal wall synthesise serotonin in response to the microbial environment around them. When your microbiome is disrupted, that production shifts — and your mood follows.
