Plasma zinc concentration responds to short-term zinc supplementation, but not zinc fortification, in young children in Senegal1,2.

What Was Tested

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

Simple, low-cost methods are needed to evaluate the effect of zinc-fortification programs.

The objective was to compare the change in plasma zinc concentrations in young children who received zinc from either a liquid supplement or a zinc-fortified complementary food.

Why It Was Studied

Plasma zinc concentration is a useful biomarker of zinc intake from supplementation, but responses to zinc fortification are inconsistent.

Who Took Part

The abstract describes 137 children taking part.

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

How the Study Was Run

In design terms this was a randomized and double-blind study.

The children 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 children and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

What Was Measured

The subject headings attached to it are Biomarkers, Dietary Supplements, Edible Grain, Food, Fortified, Infant Nutritional Physiological Phenomena, Senegal and Zinc.
