Probiotics and Vitamin D for Reducing Allergy Symptoms

This trial is investigating whether combining probiotics and vitamin D supplements can help reduce symptoms of allergic rhinitis — the common condition that causes sneezing, runny nose, congestion, and itchy eyes. Researchers believe that these two supplements together may work better than either one alone or standard treatment by helping balance your gut bacteria and supporting your immune system. You would take the medication for 12 weeks and be compared with people receiving standard care only.

While probiotics and vitamin D have been studied separately for allergic rhinitis, nobody knows yet whether combining them works even better. This trial aims to find a safe, affordable, and accessible way to help people manage allergy symptoms more effectively.
