One strain of L. reuteri implies many options. Important issues in pediatrics

Probiotics are living organisms that favor human health if administered in adequate amounts. In recent years, mechanisms of action of probiotics have been described. Moreover, strong evidence of their efficacy for preventing intestinal and respiratory infections, managing allergic and gastrointestinal disorders, and other pathologic conditions in children of different years was retrieved. Complex, physiological effects probiotics (if microbial strains are to be carefully selected and monitored for safety) contributed to the emergence of many probiotic preparations on the market. Lactobacillus reuteri, a well-known species of Lactobacillus, modulates immune response modulation, prevents infections and diseases, and is beneficial to human health. This paper addresses critical evidence of the efficacy of L. reuteri in children. Numerous clinical studies established its safety and tolerability. L. reuteri is effective for preventing and treating many diseases, including infantile colic, diarrhea, functional abdominal pain, atopic dermatitis, and allergy. L. reuteri is considered one of the available and effective medications for colic and other functional gastrointestinal disorders in children.
