Effect of vitamin D supplementation, directly or via breast milk for term infants, on serum 25 hydroxyvitamin D and related biochemistry, and propensity to infection: a randomised placebo-controlled trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc and Parathyroid Hormone (PTH 1-84), published as a randomized controlled trial.

The researchers assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant.

All babies received 15 min of sun exposure (unclothed) during massage.

Who Took Part

By PubMed's age tags, the people studied were infants, both men and women.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

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

Blinding on both sides kept the participants and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

The researchers assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant.
