Low-Dose Omega-3 Fatty Acid and Vitamin D for Anthropometric, Biochemical Blood Indices and Respiratory Function. Does it work?

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Who Took Part

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

How the Study Was Run

The researchers set it up as a randomized, double-blind, placebo-controlled and parallel-group study.

The participants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

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.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

The Vitamin D, K2, Magnesium and Zinc group and the comparison group ran side by side rather than switching.

Anthropometric, biochemical blood and respiratory indices were measured at 12 and 16 weeks.

What Was Measured

Topics PubMed links to this paper include Cholecalciferol, Dietary Supplements, Fatty Acids, Omega-3 and Vitamin D.

The authors tagged it with the keywords VO2max, anthropometric indices, blood lipids, glucose and omega-3 fatty acids.

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc.

The publication is from 2020 (International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin- und Ernahrungsforschung. Journal international de vitaminologie et de nutrition), a journal based in Singapore.
