Therapeutic effect of vitamin D supplementation on allergic rhinitis.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Who Took Part

By PubMed's age tags, the people studied were adults, both men and women.

A randomized double-blind placebo-controlled clinical trial was performed on allergic rhinitis patients with vitamin D deficiency from Nov. 2017-2018. 80 cases with allergic rhinitis and vitamin D deficiency were divided into two groups and vitamin D plus routine antihistamine medication (cetirizine) was prescribed for the study group, whereas the control group received cetirizine plus placebo.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

The subject headings attached to it are Cetirizine, Histamine H1 Antagonists, Rhinitis, Allergic, Vitamin D, Vitamin D Deficiency and Vitamins.

Author keywords: Allergic rhinitis and Serum level of vitamin D.
