Research Demonstrating Wellmune Boosts the Immune Health of Medical Students Published in Nutrition

Students reading outsideWellmune® boosted the immune systems of medical students in a new clinical study published in the peer-reviewed journal Nutrition. The research provides further evidence of this natural food, beverage and supplement ingredient’s ability to support the health of people under high stress.

Wellmune is scientifically proven to activate innate immune cells that help keep the body healthy.  Specifically, Wellmune primes neutrophils, the largest population of immune cells in the body and an important part of the body’s natural defenses.  This award-winning functional ingredient is contained in numerous foods, beverages and supplements in more than 30 countries.

“Medical students working long hours in hospitals are placing tremendous stress on their immune systems,” said Richard Fuller, M.D., of The Dove Clinic for Integrated Medicine and principal investigator for the study. “Wellmune activates innate immune cells to help protect against the harmful effects of stress.”

Study Design & Results

The study was conducted during the peak of the 2010 cold-flu season. During the 90-day, double-blind, placebo-controlled study among 100 healthy medical students, participants taking 250 mgs of Wellmune daily reported 43 fewer days of upper respiratory tract infection symptoms than their classmates who received a placebo. The results are a strong statistical trend (p=0.06). The findings were originally presented at a British Society for Immunology conference in Liverpool, UK, in 2010.

While the authors note that larger studies are needed, results of this study demonstrated that Wellmune provided real immune health benefits to the students. Specifically:

  • There was a reduction (18%) in the total number of days with self-reported URTI symptoms in Wellmune group compared to placebo.
  • In total, 24 episodes of URTI were medically confirmed, 12 episodes in each group.
  • Wellmune did not induce inflammatory cytokines. No cytokine change was seen during symptomatic URTI between study groups.

“The results are consistent with eight other clinical studies regarding the immune support effects of Wellmune,” said Don Cox, Ph.D., senior vice president of research and development at Biothera.

Biothera and its research collaborators have previously conducted clinical studies involving marathon runners, wildland firefighters, women and other individuals with high lifestyle stress. To learn more, go to
