The effect of vitamin D3 supplementation on fracture incidence in an aging population - The Finnish vitamin D trial.

What Was Tested

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

In this study, the researchers evaluated the impact of vitamin D₃ supplementation on fracture risk among an aging population in Finland.

Who Took Part

According to the abstract, 2495 participants were involved.

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

How the Study Was Run

The design is described as randomized and placebo-controlled.

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

Fracture diagnoses were retrieved from two national care notification registers.

What Was Measured

In this study, the researchers evaluated the impact of vitamin D₃ supplementation on fracture risk among an aging population in Finland.

Topics PubMed links to this paper include Fractures, Bone, Finland, Cholecalciferol, Dietary Supplements, Incidence and Aging.

The authors tagged it with the keywords Elderly, Supplementation and Vitamin D.

What This Means in Plain Language

The paper is a randomized and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc in 2495 participants.
