The effects of consuming a low-fat yogurt fortified with nano encapsulated vitamin D on serum pro-oxidant-antioxidant balance (PAB) in adults with metabolic syndrome; a randomized control trial.

What Was Tested

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

The current study aimed to assess the effect of fortified yogurt with nano-encapsulated vitamin D on serum pro-oxidant anti-oxidant balance (PAB) in adults with or without metabolic syndrome.

Before and after the intervention period, blood sample was taken to determine the serum levels of vitamin D, pro-oxidant-antioxidant balance (PAB), and high-sensitivity C-reactive protein (hs-CRP).

Who Took Part

The abstract describes 139 adults taking part.

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

The laboratory tests were checked at baseline and at the end of the treatment.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled 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.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

Topics PubMed links to this paper include Antioxidants, Diet, Fat-Restricted, Food, Fortified, Metabolic Syndrome, Nanocapsules, Oxidants and Reactive Oxygen Species.

The authors tagged it with the keywords Fortification, Nano encapsulation, Prooxidant-antioxidant balance and Vitamin D.
