Detailed description

Common cold is the most frequent acute illness in industrialised societies. Though it is usually benign, it is a leading cause of absence from work and doctor visits, causing an enormous economic burden including lost productivity and treatment costs. Common cold is caused by a variety of viruses, with rhinoviruses and corona viruses as the most common. There is currently no treatment for common cold, thus therapy is focussed on symptom relief only. Prevention strategies for common cold include lifestyle measures such as avoiding infected people and regular hand washing during cold season. Dietary supplements including herbs and vitamins have been suggested as preventive strategies for common cold. Juice Plus+® is a dietary supplement composed primarily of juice powder concentrate and pulp from fruits and vegetables. It contains several antioxidants including vitamin C, vitamin E, beta-carotene and folate. One randomized study reported reduction in work days lost to illness in the Juice Plus+® group compared to the placebo group. However, the clinical benefit for preventing common cold symptoms has not yet been tested in a large adult population.
