Vitamin D reduces eosinophilic airway inflammation in nonatopic asthma.

What Was Tested

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

The researchers sought to evaluate the effect of vitamin D supplementation on eosinophilic and neutrophilic airway inflammation in patients with nonatopic asthma.

Who Took Part

According to the abstract, 44 patients were involved.

PubMed indexes the participants as adults, middle-aged adults and older adults, both men and women.

Other measurements included questionnaires, blood samples, and pulmonary function.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

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.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

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

What Was Measured

Topics PubMed links to this paper include Asthma, Cholecalciferol, Eosinophils, Neutrophils, Pulmonary Eosinophilia, Respiratory Function Tests and Respiratory System.

The authors tagged it with the keywords airway inflammation, nonatopic and vitamin D.
