Effect of zinc supplementation on quality of life and sleep quality in young women with premenstrual syndrome: a randomized, double-blind, placebo-controlled trial.

What Was Tested

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

The aim of this study was to evaluate the effects of zinc supplementation on quality of life and sleep quality of young women diagnosed with premenstrual syndrome.

Why It Was Studied

Premenstrual syndrome is a prevalent disorder affecting a large number of women in their reproductive ages.

Who Took Part

The study group was 60 women.

PubMed indexes the participants as teenagers, young adults and adults, women only.

Pre- and post-intervention, participants completed the questionnaires of quality of life and Pittsburgh sleep quality.

How the Study Was Run

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

The women were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

Neither the women nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

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

What Was Measured

Topics PubMed links to this paper include Dietary Supplements, Premenstrual Syndrome, Quality of Life, Sleep and Zinc.

The authors tagged it with the keywords Zinc supplement.
