Magnesium Regulates Vitamin D Levels, Vanderbilt Study Finds
Table of Contents
New research from Vanderbilt-Ingram Cancer Center reveals magnesium’s crucial role in maintaining healthy vitamin D levels, potentially resolving inconsistencies in prior studies linking vitamin D to disease.
Key Findings: Magnesium as a Vitamin D Regulator
Researchers at vanderbilt-Ingram Cancer Center have discovered that magnesium plays a key role in regulating vitamin D levels within the body. A randomized clinical trial showed that magnesium supplementation increased vitamin D levels in participants who were deficient, while simultaneously reducing levels in those who already had sufficient or high amounts. This finding, published in The American Journal of Clinical Nutrition, suggests magnesium doesn’t simply boost vitamin D, but actively works to maintain levels within a healthy range.

This research adds clarity to long-standing debates surrounding vitamin D’s connection to colorectal cancer and other diseases. Previous large-scale studies, including the VITAL trial, have yielded mixed results, fueling uncertainty about vitamin D’s protective effects. The Vanderbilt team’s work offers a potential explanation for these inconsistencies.
The study builds upon earlier research conducted by the same team in 2013, which observed a correlation between low magnesium intake and low vitamin D levels.

How Magnesium regulates Vitamin D: A Novel Insight
The trial’s most significant finding was magnesium’s ability to act as a regulator. Instead of universally increasing vitamin D, magnesium appeared to normalize levels, lowering them in participants who already had sufficient amounts. This suggests a more sophisticated interaction between the two nutrients than previously understood.
This regulatory function is crucial because both vitamin D deficiency and vitamin D toxicity can pose health risks. maintaining optimal levels is key, and magnesium appears to be a critical component of this process. The researchers hypothesize that magnesium influences the enzymes involved in vitamin D metabolism,thereby controlling its activation and breakdown.
Implications for Health and Supplementation
The findings have significant implications for public health and dietary recommendations. Many individuals may be focusing solely on vitamin D supplementation without considering their magnesium intake. This study suggests that ensuring adequate magnesium levels could be just as important for optimizing vitamin D status.
Foods rich in magnesium include:
- Greens (spinach, kale)
- Beans (black beans, kidney beans)
- Whole grains (brown rice, quinoa)
- Dark chocolate
- Fatty fish (salmon, mackerel)
- Nuts (almonds
