Probiotics, gut microbiota and health

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The human gut hosts a complex ecosystem of microbiota, nutrients, and host cells essential for homeostasis and development.
• Gut microbiota performs vital metabolic, barrier, and trophic functions; dysbiosis is linked to negative health outcomes and diseases.
• The intricate relationship between gut microbiota, health, and disease drives interest in probiotics and prebiotics for modulation.

Purpose of the Study:

• This review focuses on probiotics, examining their mechanisms of action, safety profile, and significant health benefits.
• To consolidate current knowledge on the therapeutic potential of probiotics in modulating gut microbiota.

Main Methods:

• Literature review of scientific studies on probiotics and gut microbiota.
• Analysis of mechanisms of action, safety data, and reported health benefits of probiotic interventions.
• Synthesis of evidence regarding the role of probiotics in preventing or treating diseases associated with gut dysbiosis.

Main Results:

• Probiotics, as live micro-organisms, offer potential benefits by positively modulating the gut microbiota.
• Identified mechanisms include metabolic contributions, enhancement of the gut barrier function, and trophic support.
• While promising, definitive health benefits require further substantiation for specific indications.

Conclusions:

• Probiotic administration shows considerable potential for improving host health through gut microbiota modulation.
• Further research is crucial to determine optimal probiotic strains, dosages, and administration protocols for various health conditions.
• Continued investigation into probiotics is warranted given their potential therapeutic applications in managing gut health and disease.
