Your Microbiome Explained

Your gut bacteria aren't just passengers—they're active participants in your health:

1. DIGESTION

• Break down fiber into short-chain fatty acids (SCFAs)
• Produce enzymes you lack
• Synthesize vitamins (K, B12, folate)

2. IMMUNE FUNCTION

• Train immune system to recognize threats
• Produce antimicrobial compounds
• Maintain gut barrier integrity
• 70% of immune system lives in gut!

3. METABOLISM

• Influence calorie extraction from food
• Regulate fat storage
• Affect insulin sensitivity

4. BRAIN & MOOD

• Produce neurotransmitters (90% of serotonin made in gut)
• Communicate via vagus nerve
• Influence stress response

5. PROTECTION

• Compete with pathogens for space/nutrients
• Produce acids that inhibit harmful bacteria
• Break down toxins

When this system is balanced, you thrive. When it's disrupted, problems emerge.
