Gut-Brain Foundations

Explore the science of the gut-brain axis and how your digestive system communicates with your brain. Learn about the microbiome, short-chain fatty acids, neurotransmitter nutrition, inflammation, blood sugar, and key nutrients that influence mental health, grounded in 2023-2026 research.

12 Lessons 9-10 hours RCT-Supported

Course Overview

Explore the science of the gut-brain axis and how your digestive system communicates with your brain. Learn about the microbiome, short-chain fatty acids, neurotransmitter nutrition, inflammation, blood sugar, and key nutrients that influence mental health, grounded in 2023-2026 research.

What You'll Learn

  • Understand the bidirectional gut-brain axis and vagus nerve communication
  • Learn how short-chain fatty acids (SCFAs) influence brain function and mood
  • Recognize the role of intestinal permeability (leaky gut) in mental health
  • Learn how tryptophan metabolism and the kynurenine pathway affect serotonin
  • Identify key nutrients (omega-3s, vitamin D, magnesium, B vitamins) for brain health

Evidence & Clinical Approach

Built on Nutritional Psychiatry and taught at a deliberately high evidence bar: it separates well-supported practice from popular-but-contested theory, and is psychoeducation designed to support, not replace, professional care.

Frequently Asked Questions

How is this different from The Food-Mood Connection course?

The Food-Mood Connection is the practical introduction to eating for mood. Gut-Brain Foundations goes deeper into the underlying science: the vagus nerve, short-chain fatty acids, intestinal permeability, the kynurenine pathway, and the specific nutrients (omega-3s, vitamin D, magnesium, B vitamins) with the strongest research behind them. It is RCT-supported nutritional psychiatry, not general wellness advice.

Is this course a replacement for therapy?

No. It provides psychoeducation and skill-building based on evidence-based frameworks, but it is not a substitute for individualized professional treatment. It works best alongside care, as structured learning between sessions.

What if I'm currently in crisis?

If you're experiencing a mental health crisis, contact emergency services (988 Suicide & Crisis Lifeline, 911) or go to your nearest emergency room. The platform includes safety monitoring that alerts assigned providers when distress is detected.

How is this different from self-help content?

Structured, sequential lessons with interactive exercises, progress tracking, and provider oversight. Your assigned provider can see your progress and tailor sessions to what you are learning.
