Magnesium supplementation did not reduce serum calciprotein crystallization and arterial stiffness in individuals with type 2 diabetes: a randomized, double-blind, placebo-controlled trial.

What Was Tested

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

This study aimed to evaluate the effect of 6-mo oral magnesium citrate supplementation on calciprotein crystallization (T50) and carotid-femoral pulse wave velocity (cfPWV) in individuals with T2DM and peripheral MAC.

Who Took Part

The abstract describes 74 participants taking part.

PubMed indexes the participants as older adults, both men and women.

Nephelometry-based T50 measurements, cfPWV measurements, and 24-h urine collections were obtained at baseline, 3 and 6 mo.

Longitudinal analysis of covariance adjusted for baseline T50 and cfPWV was used to study the treatment effects on T50 and cfPWV.

How the Study Was Run

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

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 participants nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

What Was Measured

Topics PubMed links to this paper include Diabetes Mellitus, Type 2, Vascular Stiffness, Dietary Supplements, Magnesium, Crystallization, Citric Acid and Pulse Wave Analysis.

The authors tagged it with the keywords T(50), arterial calcification, arterial stiffness, calciprotein crystallization, carotid-femoral pulse wave velocity and diabetes mellitus type 2.
