The effects of vitamin D3 and magnesium on the body are deeply interconnected to each other. Emerging research suggests that in order to understand how vitamin D works on health, wellness, and diseases, it's important to focus on the ways magnesium works on the body. However, it’s clear so far that the discussion on vitamin D is incomplete without taking into consideration the role of magnesium. 

In this article, we’ll be discussing the correlation between vitamin D3 and magnesium in little detail. But before we get into the role of magnesium in vitamin D3 absorption, it’s important to learn the basics of vitamin D3 and magnesium a little bit more. So, let’s get started.

What is vitamin D3 and what does it do in the human body? 

Vitamin D3 or otherwise called cholecalciferol is a potent form of vitamin D, a fat-soluble group of vitamins, often considered as hormone due to its crucial role in many bodily functions. It is naturally found in many animal foods such as fatty fish, beef liver, fish oil, and various poultry and dairy products like egg yolks, yogurt, and cheese. Very few plants also contain vitamin D3 but in negligible amounts. 

People who are unable to get enough vitamin D from their foods and sun exposure, particularly those who are vegans, vegetarians, or otherwise do not take animal foods, may consider taking vitamin D3 supplements. 

Since each and every human cell has VDR or vitamin D receptors, vitamin D3 plays an essential role in many different bodily systems. Studies suggest that it can impact several cellular processes that are crucial for human health. Let’s take a look at some of the most common effects of vitamin D3 on the body:   

Beneficial effects of vitamin D3 on the body 

Vitamin D3 has been shown to have beneficial effects on a range of bodily functions. Some of the most common of them include: 

  • Stronger bones
  • Better heart health
  • Lower blood pressure
  • Healthy insulin levels
  • More stable mental health and mood
  • Lower tendency to cancer

What is magnesium and what does it do in the body? 

Magnesium is a mineral that is symbolized by “Mg” in the periodic table. It’s actually an earth metal that is alkaline in nature. Like other metals in the human body such as calcium, iron, and zinc, magnesium also does a lot for a whole variety of bodily functions ranging from the skeletal to neurological to brain functions. 

Studies revealed that magnesium has an important role in more than 600 cellular reactions and more than 300 enzymatic reactions that have a huge impact on human health. 

Magnesium is considered an essential mineral, which means the human body cannot make it on its own and it must be obtained through foods or dietary supplements to maintain optimal health. 

Magnesium is widely found in foods like whole grains, seeds, nuts, legumes, and leafy greens. But a large number of people do not get the required amount from foods alone and might want to consider magnesium supplements.  

Beneficial effects of magnesium on the body

The human body needs an adequate level of magnesium for: 

  • Bone health 
  • Heart health 
  • Muscle health 
  • Brain Health
  • A healthy sleep cycle
  • Insulin metabolism and sugar control 
  • Managing blood pressure 
  • Managing symptoms of PMS 
  • Managing mental conditions like anxiety and depression 
  • Managing migraine headaches  

The correlation between vitamin D3 and magnesium 

The human body functions cohesively as a whole and uses its vitamins and minerals in a very systematic way. The proper utilization of one substance often depends on the activity or availability of another. 

There is a deep relationship between the performance of vitamin D3 and magnesium. The pathways that activate vitamin D3 in the body involve several enzymatic reactions where magnesium plays a crucial role as a cofactor. 

There are more than 300 enzyme systems that require magnesium to work properly and obviously those that convert vitamin D3 into its usable form in the body. This form of vitamin D3 is required to help the body absorb calcium, phosphorus, as well as other important minerals.  

A 2018 review published in the Journal of the American Osteopathic Association concluded that consuming the required amount of magnesium is essential to attain the maximum benefits of vitamin D.

Should you be taking vitamin D3 and magnesium supplements together? 

In order to get optimal health, getting enough of both vitamin D and magnesium is crucial. Deficiencies or insufficiencies of vitamin D and magnesium have been found involved in developing a range of health conditions, including skeletal deformities, metabolic disorders, and cardiovascular diseases. 

Most clinicians recommend 1000 IU to 2000 IU of vitamin D3 supplements per day to fix vitamin D deficiency in average adults. But doses can be raised up to 6000 IU a day depending on the specific health conditions. Clinicians can check the vitamin D levels with a blood test to determine the exact dose. 

People who are short in dietary magnesium, which eventually affects their vitamin D status, should consider taking magnesium supplements. In general, 200 mg to 400 mg of magnesium per day is mostly recommended. Both vitamin D3 and magnesium are considered very safe supplements and can be used together safely at same time. 

Final words 

Getting enough vitamin D is critical for optimal human health and vitamin D3 supplements are the easiest option available to rectify deficiency and maintain a healthy level. But magnesium is equally important to help enzymes to transform vitamin D into a form that is usable in the body. 

If you are concerned about your magnesium level and feel your regular diet doesn’t contain sufficient magnesium-rich foods, then considering magnesium supplements along with vitamin D3 might be the best move. And, magnesium bisglycinate is one of the most effective and safest magnesium supplements.
