Why Vitamin D & Magnesium Should Be Taken Together
How Vitamin D Levels Are Affected By Low Magnesium

Magnesium aids in both vitamin D production and use. It is also needed to activate the enzymes that help the body metabolize vitamin D. A study proved using magnesium supplements alongside vitamin D supplements was more effective at remedying vitamin D deficiency than using vitamin D alone. Not only does magnesium play a key role in the proper function of vitamin D, but it also helps calcium balance.
If a patient is low in magnesium and decides to supplement vitamin D, they may be at a higher risk of obtaining calcium deposits in their arteries. However, magnesium can prevent the calcification of arteries.
Vitamin D Deficiency

Statistics indicate between forty and fifty percent of healthy individuals don’t meet their vitamin D requirements. Some of the symptoms of vitamin D deficiency include bone pain, muscle weakness, asthma in children, cognitive impairment, and an increased risk of cardiovascular disease.
The causes of vitamin D deficiency vary and include not having enough exposure to sunlight, not consuming enough vitamin D (which is likely on a vegan diet), having darker skin, kidneys unable to convert vitamin D to its active form, a digestive tract that cannot absorb vitamin D properly, and obesity. The only treatment is to get more vitamin D from diet and supplements.
