Effects of Dietary Taurine-Containing Jelly Supplementation on Academic-Related Characteristics and Academic Achievement in Korean College Entrance Examinees: A Pilot Study.

Taurine is known to play roles in fatigue recovery and relief of anxiety and stress. This pilot study was conducted to evaluate the effects of dietary taurine-containing jelly supplementation on the academic-related characteristics of Korean college entrance examinees. The jelly contained 3 g of taurine in a packet and was provided to the subjects with one packet per day for 2 weeks. The academic-related characteristics of subjects were evaluated by academic-related attitude (using School Attitude Assessment Survey-R; SAAS-R), CEES (college entrance examination stress), and SRL (self-regulated learning) and academic achievement and were conducted using a self-administered questionnaire. The total number of subjects in this study was 17, and they were divided into taurine supplementation group (n = 9, TSG) and placebo group (n = 8, PG) by randomization. The results were compared before and after 2 weeks of dietary taurine-containing jelly supplementation for each group. Statistical analysis was performed using SPSS 25.0. The total score (p = 0.069) and motivation/self-regulation score (p = 0.060) in SAAS-R tended to be significantly higher in the TSG after 2 weeks of supplementation compared to before supplementation. The score change of academic achievement in TSG was positively correlated with a total score change of SRL. In addition, as a result of simple regression analysis, a total score changes of SRL had a positive effect on a change of academic achievement score in TSG (explanatory power: 42.9%). The results of this pilot study showed that dietary taurine-containing jelly supplementation may have some effects on academic-related characteristics with a positive change in SRL. Therefore, it may be beneficial to supplement dietary taurine-containing jelly to improve academic-related characteristics such as self-regulated learning of students preparing for the college entrance exam.
