Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical trial is to evaluate the safety and effectiveness of 12-week probiotic supplementation on the incidence and duration of infectious episodes in infants aged 6 to 12 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Probiotics are live bacteria that offer a health benefit to the host when administered via the diet in adequate amounts. Probiotic supplementation is safe for use in infants to the elderly and has demonstrated beneficial effects for a wide variety of health conditions such as acute diarrhea, antibiotic-associated diarrhea, allergies, and inflammatory bowel disease. The immune-enhancing benefits of probiotics are attractive, particularly for infants, a group that is particularly prone to a variety of infections, e.g. respiratory tract infection, strep throat, and diarrhea. Probiotic supplementation has been utilized in previous studies of childhood infections with promising results.

In this study, the safety and effectiveness of 12-week probiotic supplementation on the incidence and duration of infectious episodes in infants aged 6 to 12 months will be determined. The subjects will receive follow-on formula containing 1 million CFU/g Lactobacillus rhamnosus HN001 (trademarked DR20), 1 million CFU/g Bifidobacterium animalis subsp. lactis HN019 (trademarked DR10), or placebo formula for at least three feeds per day for 12 weeks.
