Calcifediol versus vitamin D3 effects on gait speed and trunk sway in young postmenopausal women: a double-blind randomized controlled trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

The aim of this study is to test the effect of calcifediol compared with vitamin D3 on gait speed and trunk sway.

Who Took Part

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

At baseline and at 4 months of follow-up, the same physiotherapist blinded to treatment allocation tested 8-m gait speed and a body sway test battery (Sway star pitch and roll angle plus velocity while walking 8 m, and standing on both legs on a hard and soft surface).

All analyses adjusted for baseline measurement, age, and body mass index.

How the Study Was Run

The design is described as randomized and double-blind.

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.

What Was Measured

PubMed files the paper under topics including Calcifediol, Calcitriol, Cholecalciferol, Dietary Supplements, Gait, Parathyroid Hormone and Postmenopause.
