Abstract

Probiotics are living microorganisms known for their beneficial properties and have been extensively researched and utilized in various products worldwide. These microorganisms have essential nutritional needs and exhibit significant functional qualities. Probiotics have been employed to enhance the well-being of both animals and humans by influencing the balance of microorganisms in the intestines. Several probiotic strains, such as Bifidobacterium and Lactobacilli, became identified and studied for their potential to mitigate the incidence of gastrointestinal (GI) infections or as a therapeutic approach for treating such infections. With the rise of microbiota displaying resistance and tolerance to traditional medications and antibiotics, the effectiveness of drugs has diminished. Several probiotic strains have been identified to possess notable properties, including potent anti-inflammatory and anti-allergic effects. Consequently, introducing beneficial bacterial species into the GI tract offers an appealing approach to restoring microbial balance and preventing diseases. Furthermore, probiotics have demonstrated the capacity to inhibit the action of intestinal bacterial enzymes responsible being synthesizing colonic carcinogens. Probiotics offer a promising preventive and therapeutic advancement, but further research is required to better understand their specific impact on intestinal health. Probiotics can also exert a direct influence on other microorganisms, including pathogens, which is crucial in preventing and treating infections and restoring the balance of microorganisms in the GI tract. The present review deals with probiotic formulations, their mechanisms, and their role in human health.
