Poplar-type Propolis Dry Extract ESIT12 : Immunomodulation Efficacy Study
- Conditions
- Upper Respiratory Tract Infection (URTI)
- Interventions
- Dietary Supplement: PlaceboDietary Supplement: Verum
- Registration Number
- NCT05598749
- Lead Sponsor
- Fytexia
- Brief Summary
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.
