 This comprehensive review summarizes the clinical studies in infants and children, including the safety studies, to evaluate the efficacy of Probiokid®, a specific probiotic for pediatric indications combining Lactobacillus helveticus Rosell®-52, Bifidobacterium infantis Rosell®-33, Bifidobacterium bifidum Rosell®-71 and fructooligosaccharides. With a total of 28 clinical studies, Probiokid® is one of Lallemand Health Solutions most documented probiotic formulation which can be marketed under different product categories, for different uses, depending on applicable regulatory provisions. The main evidence comprises:

  • In eight studies, the probiotic enhanced immune defenses, assessed by levels of various immune competence and mucosal immunity markers (six studies), and reduced the incidence of common infections (two studies).
  • The probiotic improved iron deficiency anemia treatment efficacy (three studies), reducing the risk of unresolved anemia by 49% (RR 0.51 [0.28; 0.92]; p= 0.0263) and significantly reducing treatment side effects by 47% (RR 0.53 [0.37; 0.77]; p = 0.0009).
  • Other studies support further investigation into this probiotic for oral candidiasis, eczema, feeding intolerance in premature babies, or hyperbilirubinemia in newborns.
