Effects of Daily Intake of Calcium and Vitamin D-Enriched Milk in Healthy Postmenopausal Women: A Randomized, Controlled, Double-Blind Nutritional Study.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

Who Took Part

The abstract describes 500 women taking part.

By PubMed's age tags, the people studied were middle-aged adults and older adults, women only.

How the Study Was Run

In design terms this was a randomized and double-blind study.

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.

The researchers evaluated serum 25(OH)D, bone mineral density (BMD) by Dual Energy X-ray Absorptiometry, and biochemical data of glucose and lipid metabolism.

What Was Measured

Topics PubMed links to this paper include Absorptiometry, Photon, Anthropometry, Biomarkers, Bone Density, Calcium, Dietary, Cardiovascular Diseases and Food, Fortified.

The authors tagged it with the keywords nutritional intervention, postmenopausal and vitamin D.

What This Means in Plain Language

The paper is a randomized and double-blind study of Vitamin D, K2, Magnesium and Zinc in 500 women.

With several hundred people or more, it is a fairly large study for this kind of research.
