Gut Health Protocol.
Support digestive wellness routines with microbiome, mucosal, and meal-tolerance support without disease-care framing.
The gut health protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Gut Health Protocol is an intermediate stack of 5 supplements aimed at gut health: Probiotics, L-Glutamine, Digestive Enzymes, Berberine, and Zinc Carnosine. 2 are core and the rest are optional add-ons, at roughly $35-55/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the gut health protocol.
Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.
| Supplement | Dose | Timing | Role | Evidence |
|---|---|---|---|---|
| Probiotics | 1 cap (10B+ CFU) | Morning, empty stomach | Core | Strong |
| L-Glutamine | 5 g | Morning, empty stomach | Core | Moderate |
| Digestive Enzymes | 1 cap | With meals | Optional | Moderate |
| Berberine | 500 mg | With meals | Optional | Moderate |
| Zinc Carnosine | 75 mg | With food | Optional | Moderate |
Multi-strain formulas are studied for microbiome and digestive-symptom contexts; effects depend on strain, dose, and condition.
Primary fuel source for enterocytes and studied for gut-barrier biology; human benefit depends on population and clinical context.
Broad-spectrum enzymes may support meal tolerance in selected users; persistent digestive symptoms need clinical evaluation.
Studied for gut-microbiome and metabolic markers; antimicrobial claims are context-dependent and not a substitute for clinical care.
Clinically studied for gastric mucosal-support markers; H. pylori or ulcer symptoms require medical evaluation.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- L-Glutamine and probiotics are often paired for gut-barrier and microbiome support, with response depending on context
- Berberine and probiotics should be positioned as microbiome-support tools, not infection care
- Zinc carnosine is best framed as gastric mucosal support rather than stomach-lining restoration
