Findings from OLL1073R-1 and OLS3059 lactic acid bacteria research(7)

Yogurt fermented with OLL1073R-1 and OLS3059 lactic acid bacteria has been confirmed to reduce school absenteeism and improve learning motivation in elementary school students (human study conducted in boys and girls attending 6 elementary schools in Hachioji City, Tokyo, from 2022 to 2023).

This study was a non-consumption-controlled crossover study involving 2,179 boys and girls attending 6 elementary schools in Hachioji City. The effects of consuming yogurt fermented with OLL1073R-1 and OLS3059 lactic acid bacteria for 8 weeks on the number of days absent from school, motivation to learn, and interpersonal relationships were analyzed.

The results suggested that consuming yogurt fermented with OLL1073R-1 and OLS3059 lactic acid bacteria may reduce symptoms in students who are absent from school.
