Effects of Zinc Supplementation on Metabolomic Profiles in Tanzanian Infants: A Randomized Trial.

What Was Tested

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

This study aimed to examine the effect of zinc supplementation on metabolic profiles in Tanzanian infants aged 6 wk and 6 mo.

Two-way repeated measures analysis of variance with compound symmetry covariance structures were used to compare metabolome levels over time between infants in the 2 treatment arms.

Why It Was Studied

However, the metabolic pathways underlying these outcomes are unclear, and metabolomic data from humans undergoing zinc supplementation, particularly infants, are generally lacking.

Who Took Part

The abstract describes 50 infants taking part.

By PubMed's age tags, the people studied were infants, young children and children.

How the Study Was Run

The design is described as randomized, double-blind 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.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

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

Principal component analysis (PCA) was used to summarize metabolomic data from all samples.

What Was Measured

However, the metabolic pathways underlying these outcomes are unclear, and metabolomic data from humans undergoing zinc supplementation, particularly infants, are generally lacking.

PubMed files the paper under topics including Zinc, Tanzania, Dietary Supplements and Morbidity.

The authors tagged it with the keywords infants, metabolomic analysis, randomized controlled trial and zinc supplementation.
