Short Report: Influence of Dark Chocolate Intake on Magnesium Status in Hemodialysis Patients.

What Was Tested

This clinical trial looks at Vitamin D, K2, Magnesium and Zinc.

Dark chocolate is an excellent source of Mg2+.

Who Took Part

The study group was 59 patients.

PubMed indexes the participants as adults and middle-aged adults, both men and women.

The study included 59 patients undergoing HD.

Patients were allocated into 2 groups: dark chocolate and the control group.

How the Study Was Run

The researchers set it up as a pilot study.

It is described as a pilot, a small early test of whether a larger Vitamin D, K2, Magnesium and Zinc study would be practical.

These are secondary analyses from a previous controlled pilot study.

The control group did not receive any intervention.

Mg2+ was evaluated by a colorimetric test using a commercial kit (Bioclin®).

NCT04600258 on March 1, 2020, retrospectively registered.

What Was Measured

PubMed files the paper under topics including Chocolate, Magnesium, Magnesium Deficiency, Pilot Projects, Renal Dialysis and Renal Insufficiency, Chronic.

The authors tagged it with the keywords bioactive compounds, chronic kidney disease, dark chocolate and hemodialysis.
