What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial paper looks at Vitamin D, K2, Magnesium and Zinc in the context of low blood pressure and orthostatic hypotension.

The aim of the post hoc analysis of this one-year study is to investigate the effects of MK-7 supplementation on the vascular parameters in pre-, peri-, and post-menopausal women.

Why It Was Studied

Menaquinone-7 (MK-7) is a fat-soluble vitamin involved in coagulation and maintaining vascular health.

Pre-, peri-, and post-menopausal women were subdivided according to arterial stiffness, with a high b-stiffness index defined as being greater than the overall median of 9.83.

Who Took Part

The study group was 165 women.

PubMed indexes the participants as middle-aged adults and older adults, women only.

Established vascular parameters were measured before and after one year of vitamin K2 supplementation.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

The women were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

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.

The timeline in the abstract includes one year.

What Was Measured

The subject headings attached to it are Vitamin K 2, Postmenopause, Vascular Stiffness, Dietary Supplements, Blood Pressure, Calcium-Binding Proteins and Matrix Gla Protein.

Author keywords: post-menopause, pre/peri-menopause and vitamin k homeostasis.

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc in 165 women in people with low blood pressure and orthostatic hypotension over one year.

The publication is from 2025 (Nutrients), a journal based in Switzerland.
