Weekly iron supplementation does not block increases in serum zinc due to weekly zinc supplementation in Bangladeshi infants.

What Was Tested

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

Because infants and young children in many developing countries are deficient in both iron and zinc, and zinc can affect iron metabolism, evaluation of optimum strategies to simultaneously supplement iron and zinc is an important public health priority.

Who Took Part

PubMed indexes the participants as infants, both men and women.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

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

Hemoglobin, serum ferritin, transferrin receptor, zinc, and copper concentrations were measured at baseline and at the end of intervention.

What Was Measured

Because infants and young children in many developing countries are deficient in both iron and zinc, and zinc can affect iron metabolism, evaluation of optimum strategies to simultaneously supplement iron and zinc is an important public health priority.

What This Means in Plain Language

The paper is a randomized and double-blind study of Vitamin D, K2, Magnesium and Zinc and Copper (Supplement).

The publication is from 2005 (The Journal of nutrition), a journal based in United States.
