A Vitamin D-Calcium-Fortified Yogurt Drink Decreased Serum PTH but did not Affect Osteocalcin in Subjects with Type 2 Diabetes.

What Was Tested

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

Who Took Part

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

Ninety women and men aged 30 - 50 years old with type 2 diabetes were randomly divided into three groups in a double-blind manner.

Anthropometric and biochemical assessments were made, including 25(OH), intact parathyroid hormone (iPTH), osteocalcin, and calcium.

How the Study Was Run

The design is described as randomized and double-blind.

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.

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

Group 1 (PD), the control group, received a plain yogurt drink.

What Was Measured

The subject headings attached to it are Beverages, Calcium, Dietary, Cholecalciferol, Diabetes Mellitus, Type 2, Food, Fortified, Nutritional Status and Osteocalcin.

Author keywords: bone, fortified yogurt drink and vitamin D.
