Study shows Wellmune® reduces duration of cold/flu symptoms for highly stressed adults.
Study: Medical Students
Lifestyle stress has been shown to suppress the immune system, putting otherwise healthy individuals at risk—especially during cold-and-flu season. In this study, Wellmune demonstrated a strong trend towards reducing the duration of upper respiratory tract infection (URTI) symptoms for medical students.
|Study Site||University of Southampton School of Medicine, UK|
|Population||97 fourth-year medical school students|
|Age||18-65 (average 21 years)|
|Design||Randomized, double-blinded, placebo-controlled, parallel arm study|
Participants were split into two groups, and consumed one of the following once daily:
Participants completed a daily health diary recording presence or absence of URTI symptoms. Two or more reported symptoms for two consecutive days triggered a medical assessment and cytokine analysis within 24 hours.
24 episodes of URTIs were medically confirmed; 12 in each group.
- Participants taking Wellmune experienced a significant reduction in URTI symptoms.
- Wellmune did not stimulate the immune system with inflammatory cytokines when subjects were not experiencing a URTI.
Participants taking Wellmune had an 18% reduction in the total days with URTI symptoms compared to placebo.
