BPC-157 for Food Sensitivities Research: Protocol Comparison
BPC-157 (Injectable) Tight junction repair via FAK/VEGF pathways + TNF-α/IL-6 suppression 250–500 µg SQ daily (human-equivalent from rodent data) Intestinal permeability (lactulose/mannitol), serum zonulin, cytokine panels, symptom scores 7–14 days for barrier
This comparison does not assign a generated winner or score.
- BPC-157 (Injectable)
- Tight junction repair via FAK/VEGF pathways + TNF-α/IL-6 suppression
- 250–500 µg SQ daily (human-equivalent from rodent data)
- Intestinal permeability (lactulose/mannitol), serum zonulin, cytokine panels, symptom scores
- 7–14 days for barrier markers; 21–28 days for symptom reduction
- Most mechanistically targeted for structural repair; limited human clinical data; requires precise peptide purity
- L-Glutamine (5–15g daily)
- Enterocyte fuel source; supports tight junction protein synthesis
- 5–15g oral powder daily
- Symptom questionnaires, subjective tolerance improvements
- 4–8 weeks
- Well-tolerated, affordable; effect size modest; doesn't address inflammatory cytokines
- Elimination Diet (IgG-guided)
- Antigen avoidance to reduce immune activation
- Remove reactive foods 6–12 weeks, structured reintroduction
- Symptom resolution, IgG antibody titers (unreliable marker)
- 6–12 weeks symptom improvement; indefinite for tolerance
- Symptom control effective; doesn't repair underlying permeability; reintroduction often fails
- Probiotic Therapy (Multi-strain)
- Microbial modulation; possible zonulin downregulation
- 25–100 billion CFU daily
- Stool microbiome analysis, symptom scores
- 8–12 weeks
- Indirect mechanism; strain-dependent; synergistic with barrier repair but insufficient alone
- Low-FODMAP Diet
- Reduces osmotic load and bacterial fermentation byproducts
- Strict 4–6 weeks, gradual reintroduction
- Symptom scores (bloating, pain, transit time)
- 2–4 weeks symptom improvement
- Addresses fermentation triggers, not immune reactivity; restrictive; doesn't restore tolerance
- Quercetin + Vitamin C
- Mast cell stabilisation; histamine metabolism support
- 500mg quercetin + 1000mg vitamin C twice daily
- Histamine symptom scores, DAO enzyme activity
- 4–6 weeks
- Useful for histamine intolerance subset; doesn't address tight junction defects
