Kinetics and concentrations of circulating 25-hydroxyvitamin D using different vitamin D repletion regimens.

What Was Tested

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

Vitamin D deficiency is common throughout the world.

While guidelines for vitamin D replacement exist, they have not been tested in Armenia.

Why It Was Studied

Vitamin D repletion guidelines in Armenia were untested.

Providers may determine the replacement strategy based on patient variables.

Who Took Part

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

The researchers recruited community-dwelling adults in Yerevan, Armenia, who were found to be deficient in vitamin D.

How the Study Was Run

The design is described as randomized.

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

Circulating levels of 25(OH)D were measured at baseline, and at weeks 4, 8, 12, 24, and 36.

What Was Measured

Vitamin D repletion guidelines in Armenia were untested.

The subject headings attached to it are Vitamin D, Vitamin D Deficiency and Dietary Supplements.

The authors tagged it with the keywords Armenia, Repletion and Supplementation.
