Intelligent Delivery of Probiotics and Postbiotics: Shaping Microbial Therapies
A narrative review maps encapsulation and controlled-release strategies for probiotics and postbiotics aimed at overcoming gastrointestinal barriers.
Context
Probiotic viability in the gastrointestinal tract is compromised by pH, bile salts, and heat. Smart delivery systems are proposed to protect bioactive agents and improve therapeutic outcomes.
What the study showed
The abstract describes current encapsulation platforms — hydrogels, nanoparticles, and stimulus-responsive materials — applied to probiotics and postbiotics. Site-specific intestinal release mechanisms are discussed. No primary data, clinical trial results, or quantitative outcomes are reported.
How it was done
Narrative review published in Biomolecules (2025). No study population, no defined sample size, no follow-up period. Analysis is based solely on the available abstract.
Limitations
Narrative reviews lack systematic synthesis and meta-analytic rigor; without explicit inclusion criteria, selection bias cannot be assessed. Analysis is limited to the abstract — full-text conclusions may differ.
In clinical practice
No direct clinical recommendation is supported by this study type. The paper provides a landscape of emerging technologies, not a basis for practice change.
