Gut Health and Nutrient Absorption
You can eat perfectly and still be deficient. Poor gut health blocks nutrient absorption — and most people never find out. Here's what's actually happening
Key Findings
- Up to 70% of your immune system resides in your gut
- Leaky gut syndrome can reduce nutrient absorption by up to 50%
- 90% of serotonin (the 'happiness chemical') is produced in the gut, not the brain
- Antibiotics can disrupt gut bacteria for up to 12 months after a single course
Key Nutrients
- Probiotics — Restores beneficial gut bacteria that aid nutrient absorption and immune function
- L-Glutamine — Repairs intestinal lining and reduces gut permeability ('leaky gut')
- Zinc — Essential for gut lining integrity and immune function within the gut
- Vitamin A — Maintains the mucosal barrier of the intestinal wall
- Digestive Enzymes — Breaks down food more efficiently for better nutrient extraction
- Methylcobalamin (Active B12) — B12 absorption depends entirely on intrinsic factor in the gut — compromised gut health directly causes B12 deficiency even with adequate dietary intake
- Magnesium — Frequently low with gut dysfunction; required for 300+ enzymatic reactions and often poorly absorbed when gut lining is compromised
The Bottom Line
You're not just what you eat — you're what you absorb. If your gut health is compromised, even the best diet and supplements won't fully work. Prioritizing gut repair through fermented foods, targeted nutrients, and reducing gut irritants is often the missing step in any health improvement plan.
