Researchers from Chulalongkorn University in Bangkok, Thailand, recently conducted the largest ever clinical study on Essence of Chicken (EC). In this study, Essence of Chicken was compared against a placebo protein drink. The study, published in Nutrients*, a peer-reviewed open access journal of human nutrition, concluded that consumption of Essence of Chicken improves working memory among healthy adults. Furthermore, healthy people with higher levels of everyday stress experience greater benefit in memory improvement.
Essence of Chicken Improves Working Memory in Healthy Adults
Essence of Chicken consumption was shown to improve working memory in healthy adults, particularly in challenging memory tasks. Figure 1 shows that study participants consuming Essence of Chicken improved by 8.5% from their baseline scores, with benefits seen within the first week of daily consumption.
Working memory is the ability to remember new information while using it in some way and it is crucial to everyday function. For example, for students answering a multiple choice question, working memory is used to remember the question and all options while deciding on the correct answer. For executives, workinig memory is used during meetings to remember facts and figures presented for decision-making.
Hence, consumption of Essence of Chicken can help healthy adults hold and process information better in their daily life with an enhanced working memory performance.
Participants with Higher Stress Levels See Greater Memory Benefit with Essence of Chicken Consumption
Researchers also found that in participants with higher stress levels, Essence of Chicken consumption improved memory performance even in simple memory tasks, in addition to the challenging tasks. Thus, people who have higher levels of stress may experience greater benefits from Essence of Chicken consumption.
Figure 2(a) shows that moderately stressed participants consuming Essence of Chicken improved memory by 10% from their baseline scores in the simple memory task. Figure 2(b) shows an even larger improvement of 20% among severely stressed participants.
“These study findings support that Essence of Chicken consumption can improve working memory in healthy adults and particularly when there is a higher level of daily life stress,” concluded the researchers from Chulalongkorn University who conducted the study.
To date, this is the largest clinical study ever done to measure the effectiveness of Essence of Chicken on cognitive function improvement. In this study, participants consumed 2 bottles of Essence of Chicken per day. Three earlier Essence of Chicken studies have used 1 bottle per day dosage and have similarly shown improved working memory as well.# As cognition comprises many different functions, e.g. memory, planning, creativity, the sponsors of this study intend to continue to explore the potential beneficial enhancement effects of Essence of Chicken.

This is the largest clinical study conducted on the effectiveness of Essence of Chicken to date, with 235 participants. Of the 235 healthy adults from the Asian population who completed the study, there were 117 participants in the Essence of Chicken Group and 118 participants in the placebo group. In this study, participants drank 2 bottles of Essence of Chicken per day.
