What This Study Did, in Plain Language
What Was Tested
The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.
Aim: The aim of this study was to examine the effect of whey protein and vitamin D supplementation on body composition and skeletal muscle in older adults living in long-term care facilities.
Why It Was Studied
Methods: This study is a double-blind randomized controlled trial.
Who Took Part
PubMed indexes the participants as middle-aged adults and older adults.
Thirty older adults (>60 years old) were randomized and allocated in three groups: group receiving resistance training and supplementation receiving resistance training, whey protein and vitamin D; group received resistance and placebo training receiving resistance training and placebo, and control group without any intervention.
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.
Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.
Body composition was measured by dual-energy X-ray absorptiometry at baseline, 12 weeks, and 24 weeks.
What Was Measured
PubMed files the paper under topics including Whey Proteins, Muscle Strength, Dietary Supplements, Muscle, Skeletal, Vitamins, Vitamin D and Resistance Training.
The authors tagged it with the keywords Elderly and body composition.
What This Means in Plain Language
The paper is a randomized, double-blind and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc.
The publication is from 2023 (Nutrition and health), a journal based in England.
