Summary
The goal of this clinical trial is to learn if taking probiotics, vitamin D, or both together can help lower symptoms of allergic rhinitis (AR) and improve quality of life in adults. Allergic rhinitis is a condition that causes sneezing, nasal congestion, and itchy or watery eyes.
The main questions this study aims to answer are:
Do these supplements improve the quality of life for people with AR?
Researchers will compare four groups:
* People taking probiotics and vitamin D
* People receiving standard treatment only (control group)
Participants will:
* Take a probiotic capsule daily and/or a vitamin D tablet (based on blood levels) for 12 weeks
* Continue standard allergic rhinitis treatment (like antihistamines or nasal sprays)
* Visit the clinic for checkups and lab tests
* Complete surveys about their symptoms and quality of life
This study will help researchers understand if adding probiotics and/or vitamin D to standard care can help people with allergic rhinitis feel better.
