Effect of Vitamin D Supplementation on Glycemic Control in Patients With Type 2 Diabetes (SUNNY Trial): A Randomized Placebo-Controlled Trial.

What Was Tested

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

The purpose of their study was to evaluate the effect of vitamin D supplementation on glycemic control in patients with type 2 diabetes.

To assess the primary outcome of the study, change in HbA(1c), the researchers performed a linear regression analysis.

Who Took Part

The study group was 275 patients.

The age groups tagged for this paper are middle-aged adults and older adults, both men and women.

This randomized, double-blind, placebo-controlled trial was conducted in 275 adult patients with type 2 diabetes without insulin treatment.

How the Study Was Run

The researchers set it up as 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.

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

Some patients received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

PubMed files the paper under topics including Blood Glucose, Diabetes Mellitus, Type 2, Dietary Supplements, Hypoglycemic Agents and Vitamin D.
