Poplar-type Propolis Dry Extract ESIT12 : Immunomodulation Efficacy Study

February 23, 2024 updated by: Fytexia

Evaluation of the Immunomodulation Effect of ESIT12, a Poplar-type Propolis Dry Extract and Its Efficacy in Subjects at Risk of Contracting Upper Respiratory Tract Infections (URTIs)

The aim of the present investigation is to evaluate the immunomodulation effect of ESIT12, a poplar-type propolis dry extract standardized in polyphenols, and its efficacy in subjects at risk of contracting upper respiratory tract infections (URTIs), during a 12-week supplementation period plus 4-week follow-up.

The number of onset of upper respiratory tract infections, the symptoms severity and lasting and interferences with well-being will be assessed with WURSS-24 questionnaire. The quality of life will be assessed with the SF-36 questionnaire and a testimonial. Blood immune markers will also be assessed. Finally, long lasting benefits will additionally be evaluated 4 weeks after end of the supplementation period. The design of the study is double-blind, randomized, parallel and placebo controlled.
