Brief Summary

The purpose of this study is to determine the effect of Bacopa Monnieri on working memory and cognitive processing in student.

Detailed Description

Learning and working memory are two of the key role for studying and work successful for student particular the high school student who study hard and preparing themselves for the graduate study. The consumption of brain booster product or functional food for improving memory has gained much attention. It has been reported that Bacopa Monnieri could improve learning and working memory in elderly subject by improving the N100 and P300 event related potential. Therefore, Bacopa Monnieri might be the potential product for improving the learning and working memory in student particular high school student.
