Probiotics and vitamin D for hay fever relief
Part of Ear, nose & throat, Hormones & metabolism, Immune system & allergy, Lungs & breathing clinical trials.
This study tests whether taking a combination of probiotics (good bacteria) and vitamin D can help reduce hay fever symptoms. It may be a good option if your vitamin D is low and you haven't used probiotics recently.
