This study investigates the effects of a dietary supplement - a cocktail of vitamins and minerals - on the incidence of common cold in a cohort of middle management employees.The primary outcome is defined as the number of duty days lost due to common cold/flu. Further, immune parameters and markers of redox biology/oxidative stress will be determined. The wellbeing in the cohort will be evaluated via questionnaires.

Condition Intervention
Immune System Diseases Dietary Supplement: vitamines and minerals Dietary Supplement: placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: Influence of Micronutrient Supplementation on Duty Days Lost Due to Flu/Common Cold, Immune System, Oxidative Stress and Wellbeing in a Cohort of Middle Management Employees

Further study details as provided by Lamprecht Manfred PhD, PhD, Green Beat:

Primary Outcome Measures:
  • Incidence of common cold [ Time Frame: 24 weeks ]
    vitamins and minerals might influence the incidence of common cold in middle aged management employees

Secondary Outcome Measures:
  • change in immune markers [ Time Frame: 24 weeks ]
    cytokine levels and expression of cytokine receptors in leucocytes may change over time due to micronutrient intervention

Other Outcome Measures:
  • change in redox biology [ Time Frame: 24 weeks ]
    micronutrients may influence redox biology of subjects

Enrollment: 82
Study Start Date: April 2014
