Effect of Vitamin D Therapy on Sexual Function in Women with Sexual Dysfunction and Vitamin D Deficiency: A Randomized, Double-Blind, Placebo Controlled Clinical Trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc in the context of sexual function & libido (women and men), published as a randomized controlled trial.

The researchers investigated the effect of vitamin D therapy on sexual function in women with low vitamin D levels and sexual dysfunction.

Who Took Part

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

The researchers performed this randomized, double-blind, placebo controlled trial in women 18 to 45 years old with sexual dysfunction, defined as a FSFI (Female Sexual Functioning Index) score less than 26.55, and serum 25[OH]D less than 30 ng/ml.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

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

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.

Sexual function was evaluated with the FSFI at baseline, and 4 and 8 weeks.

The serum level of 25[OH]D was measured and depression symptoms were evaluated by the BDI (Beck Depression Inventory) at baseline and 8 weeks.

What Was Measured

PubMed files the paper under topics including Dietary Supplements, Risk Assessment, Sexual Dysfunction, Physiological, Vitamin D and Vitamin D Deficiency.

The authors tagged it with the keywords depression, psychological, sexual dysfunctions and women's health.
