The Microbiome Map
Your digestive tract is a complex ecosystem. Each region has unique pH levels and bacterial populations with specialized roles.
Stomach
pH 1.5-3.5 (Highly Acidic)
Predominant Bacteria:
- • Helicobacter pylori
- • Lactobacillus
Harsh acidic environment that kills most bacteria and begins protein digestion.

Colon
pH 5.5-7 (Slightly Acidic to Neutral)
Predominant Bacteria:
- • Bacteroidetes
