Unveiling The Therapeutic Potential of Probiotics: A Review

Abstract

Probiotics, live microorganisms conferring health benefits, have emerged as a vital consideration in managing various human diseases. Since Élie Metchnikoff introduced the concept in the early 20th century, research has extensively explored probiotics' therapeutic utility in immune modulation, gut microbiota balance, and gut barrier integrity. Notable strains, such as Lactobacillus acidophilus, Bifidobacterium breve , and Saccharomyces boulardii , have demonstrated anti-inflammatory, antimicrobial, and immune-modulating effects. Probiotics have shown promise in preventing and managing dental caries, periodontitis, gingivitis, halitosis, and gastrointestinal diseases like irritable bowel syndrome and inflammatory bowel disease. Randomized controlled trials have revealed significant improvements in periodontal health and reductions in volatile sulfur compounds. Probiotics' mechanisms include gut microbiota modulation, intestinal inflammation reduction, and gut barrier restoration. Probiotics have potential in cancer prevention and treatment, influencing colorectal cancer outcomes and exhibiting adjunct therapeutic effects for oral cancer. Beyond gastrointestinal and oral diseases, probiotics have systemic effects on metabolic, allergic, neurological, and psychiatric disorders. Future trends include selective and genetically tailored probiotics for specific diseases, leveraging advancements in omics technologies. The multifunctional nature of probiotics holds great promise for individualized disease treatment and health optimization, aligning with the principle of precision medicine.
