Probiotic Supplement May Help Boost Immune System Function in Children in Daycare
Children in daycare tend to get sick more often, particularly when it comes to the common cold, upper respiratory infections, or pink eye. Taking a supplement containing Lactobacillus plantarum HEAL9 and Lactobacillus paracasei 8700:2 may lessen the severity of upper respiratory infections and reduce the number of absences from daycare.
Participants in the study included 106 children between the ages of 1 and 6 who attended daycare during the study period. Half of them were given 109 CFU of the probiotic supplement or a placebo daily for 3 months. The participants’ guardians completed an electronic study diary every day that recorded the participants’ health and whether they had attended daycare or not.
Participants in the probiotic group saw significantly reduced severity of the symptoms labeled nasal congestion/runny nose and crying more than usual, compared to the placebo group. They also had a reduction in absences from daycare, 1.7 days compared to 2.4 days for the placebo group.
The study was conducted by researchers from Probi AB. It was published online ahead of print on November 16, 2019 in the European Journal of Nutrition.
