The effects of iron supplementation on serum copper and zinc levels in pregnant women with high-normal hemoglobin.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc and Copper (Supplement).

To evaluate the effect of iron supplementation on serum copper and zinc levels.

Who Took Part

According to the abstract, 66 women were involved.

PubMed tags the participants as women only.

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.

Neither the women nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

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

Hemoglobin, ferritin, copper, and zinc levels at 24-28 and 32-36 weeks of pregnancy were measured and compared.

What Was Measured

The subject headings attached to it are Copper, Ferrous Compounds, Hematinics, Hemoglobins and Zinc.
