Evaluation of clinical safety and tolerance of a Lactobacillus reuteri NCIMB 30242 supplement capsule: a randomized control trial.
A significant number of human clinical trials have reported no adverse effects associated with consumption of Lactobacillus reuteri ( L. reuteri ) . In the present study , the clinical safety and toxicology of oral ingestion of supplement capsules containing L. reuteri NCIMB 30242 was investigated . A r and omized group of 131 subjects received a dose of 2.9 × 10⁹ CFU L. reuteri NCIMB 30242 capsules ( n=67 ) or placebo capsules ( n=64 ) twice daily for 9 weeks . Clinical chemistry and hematological parameters of safety were analyzed . The frequency , duration and intensity of adverse events (AE)s and clinical significance of safety parameters were recorded for both groups . No clinical ly significant differences between the probiotic capsule and placebo capsule treated groups were detected in either the blood clinical chemistry or hematology results . The frequency and intensity of AEs was similar in the two groups . These results demonstrate that administration of a twice daily dose of 2.9 × 10⁹ CFU was safe and well tolerated in the population evaluated over 9 weeks
