Abstract

Background: Fatigue is attributable to physical and psychological stress. Fatigue is also a common symptom which occurs in both sick and healthy individuals. Although its mechanism of cause is complex, fatigue from stress is known to affect the existing equilibrium of the immune system. However, nutrition, such as beta-1,3/1,6 glucan, has been reported to play an important role in regulating stress and fatigue states, via modulating a weakened immune system. In this study, a popular and healthy beverage in Okinawa, Japan, containing a soluble baker’s yeast in black koji vinegar (Moromisu), was provided to healthy subjects with a non-strenuous daily lifestyle.

Results: By performing statistical analysis on the results of the Profile of Mood States (POMS) survey, we observed that overall study results (n=14) demonstrated significant differences in fatigue and confusion in the POMS factors.

Conclusions: In this study we confirmed that beta-1,3/1,6 glucan improved some of the factors related to stress and fatigue, as indicated by evaluation of POMS survey results.

Key Words: Beta-1,3/1,6-glucan, vinegar, POMS, stress
