Effects of vitamin D supplementation on metabolic and endocrine parameters in healthy premenopausal women: A randomized controlled trial.

What Was Tested

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

Vitamin D supplementation may affect glycemic as well as hormonal regulation.

Primary outcome measure was the plasma glucose area under the curve (AUCgluc).

Who Took Part

The age groups tagged for this paper are adults, women only.

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.

Blinding on both sides kept the participants and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

The current study was a single-center, double-blind, randomized placebo-controlled trial that was conducted at the Medical University of Graz, Austria, between March 2013 and October 2017.

What Was Measured

PubMed files the paper under topics including Austria, Blood Glucose, Dietary Supplements, Premenopause, Vitamin D and Vitamins.

The authors tagged it with the keywords Insulin resistance, Premenopausal, RCT and Vitamin D supplementation.
