- Simultaneous dosing
- 1 × 10^10 CFU L. plantarum
- Probiotic + peptide taken together
- 8–12% vs peptide-only
- Minimal benefit. Bacterial metabolites haven't accumulated; proteolytic enzymes remain active during peptide exposure
- 30-minute pre-dose
- Probiotic 30 min before peptide
- 18–22% vs peptide-only
- Partial benefit. Some SCFA accumulation but tight junction remodeling incomplete; absorption window opens too late
- 60–90 minute pre-dose
- 1 × 10^10 CFU L. plantarum or B. longum
- Probiotic 60–90 min before peptide
- 35–40% vs peptide-only
- Optimal timing. Claudin-2 upregulation peaks at 75–90 min; DPP-IV inhibition maximized; peptide arrives during full permeability window
- 120-minute pre-dose
- Probiotic 120 min before peptide
- 15–20% vs peptide-only
- Declining benefit. Tight junction remodeling begins reverting to baseline; metabolite concentrations dropping as bacterial fermentation slows
- Post-peptide probiotic
- Peptide first, probiotic 60 min later
- 0–5% vs peptide-only
- No measurable benefit. Peptide degraded before barrier modulation occurs; reverse timing negates the mechanism entirely
