Probiotics: The Microbial Workforce
• Compete with harmful bacteria for space and resources
• Strengthen gut lining to prevent leaky gut
• Train immune system responses via GALT Gut Associated Lymphoid Tissue
• Produce vitamins B vitamins Vitamin K
• Influence gut brain axis communication

Prebiotics: The Nourishment
• Selectively fermented by beneficial bacteria in colon
• Fuel growth of good bacteria bifidobacteria lactobacilli
• Produce Short Chain Fatty Acids SCFAs with critical functions:
