Evolution of Serum 25OHD in Response to Vitamin D3-Fortified Yogurts Consumed by Healthy Menopausal Women: A 6-Month Randomized Controlled Trial Assessing the Interactions between Doses, Baseline Vitamin D Status, and Seasonality.

What Was Tested

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

Using fortified yogurt, the researchers investigated in one randomized controlled trial how both baseline status, as assessed by measuring s25OHD prior the onset of the trial, and the season of enrollment quantitatively influenced the response to the supplemented (Suppl.) of vitamin D3 (VitD3) in healthy community-dwelling women.

Who Took Part

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

A 24-week controlled trial was conducted in menopausal women (mean age: 61.5).

How the Study Was Run

The researchers set it up as a randomized study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

The 16 intervention weeks lasted from early January to mid-August, the 8 follow-up weeks, without product, from late August to mid-October.

What Was Measured

Topics PubMed links to this paper include Cholecalciferol, Food, Fortified, Menopause, Seasons, Vitamin D, Vitamin D Deficiency and Yogurt.

The authors tagged it with the keywords Nutritional intervention, menopausal women, seasonality interaction and vitamin D3–fortified yogurts.
