Efficacy:

BRAND'S^® Essence of Chicken is able to reduce mental fatigue and thus improve concentration on mental work.

Method:

A group of healthy, non-BRAND'S^® Essence of Chicken users (male students) were divided into 2 groups: the BRAND'S^® Essence of Chicken group and the Placebo group. 2 bottles of BRAND'S^® Essence of Chicken or Placebo were taken every morning for 1 week. On the final day, the subjects' task performance and mood states were studied. The 2 mental workload tests performed were a mental arithmetic test (MAT) and a short-term memory test (SMT), correlated to a substance in the body called cortisol.

Findings:

The task performance of subjects performing the MAT and SMT improved with BRAND'S^® Essence of Chicken consumption. The error rate of the BRAND'S^® Essence of Chicken group was less than the rate in the Placebo group. Subjects also felt more active and less fatigued during the workload. It was therefore concluded that BRAND'S^® Essence of Chicken has the potential to metabolise cortisol (a stress-related substance) in blood and to promote recovery from mental fatigue.

Implication to consumers:

When we are mentally overworked, our mind gets tired easily and our level of concentration is reduced, affecting work efficiency. On top of that, we get stressed easily when we cannot cope with work, upsetting our systems and affecting our moods. BRAND'S^® Essence of Chicken is proven to reduce mental fatigue. It is very helpful for students studying for exams and for anybody who needs to think hard at the office.
