Effects of sunlight exposure and vitamin D supplementation on vitamin D levels in postmenopausal women in rural Thailand: A randomized controlled trial.

What Was Tested

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

Despite the abundant sunlight in Thailand, vitamin D deficiency is common in premenopausal and postmenopausal Thai women.

Who Took Part

The abstract describes 52 women taking part.

The age groups tagged for this paper are middle-aged adults and older adults, women only.

A 12-week randomized controlled trial was conducted in 52 postmenopausal women, age 50-70 years.

The participants were randomized to either the sunlight exposure group or the sunlight exposure with vitamin D supplementation group.

How the Study Was Run

The design is described as randomized.

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.

Serum 25(OH)D concentration and parathyroid hormone (PTH) were measured using standard assays at baseline and 12 weeks.

What Was Measured

PubMed files the paper under topics including Dietary Supplements, Postmenopause, Rural Population, Sunlight, Thailand, Vitamin D and Vitamin D Deficiency.

The authors tagged it with the keywords Postmenopausal women and Vitamin D2.
