Magnesium intake modulates vitamin D status

Nutrients can often interact in our bodies in complex ways. This study found that magnesium intake influences vitamin D levels in complex ways that depend on baseline vitamin D status.

Study under review: Magnesium status and supplementation influence vitamin D status and metabolism: results from a randomized trial.

Introduction

Vitamin D plays many important roles[1] in the human body besides its well-known effect on bone health. Most cells, including those from the immune system, express the vitamin D receptor, highlighting the multiple roles of this vitamin for human health.

In humans, vitamin D is synthesized[2] from exposure to sunshine. Ultraviolet B radiation converts 7-dehydrocholesterol to previtamin D3, which is then rapidly converted to vitamin D3. Vitamin D can also be obtained through natural (fish, egg yolks, etc.) or fortified food sources (dairy, etc.) or supplements containing either D3 or D2.
