The Magnesium Factor

In my last post, I talked about the relationship among magnesium, calcium, Vitamin D, and Vitamin K. Today, I’m going to share my thoughts on why supplementing magnesium is important, what magnesium’s role in the synergy is, and when and how to supplement magnesium.

PLEASE NOTE: In my 2017 Edition of The Magnesium Miracle, I recommend using ReMag for its absorption, Natural Calm for constipation only, and Epsom salts for baths and footbaths. These are the only magnesium supplement recommendations I currently make.

Why Should I Supplement Magnesium?

In my post, How Do I Know I Am Magnesium Deficient, I detail some of the reasons why magnesium is so important:

Magnesium is a co-factor for more than 1,000 enzyme reactions that provide vital metabolic functions in the body. Additionally, magnesium regulates genomic stability, energy status and antioxidant capacity of the cell. Moreover, magnesium and calcium have similar chemical properties, but their role in biological systems is counterintuitively antagonistic. This antagonism drives functions such as relaxing (magnesium) and contracting (calcium) muscles. Think of your heart beating, your knee bending and straightening, and you’ll understand the relationship between magnesium and calcium.

Since many magnesium experts, including me, believe that more than 80% of the world’s population is magnesium deficient, magnesium supplementation only makes sense.

What Role Does Magnesium Play?

As mentioned above, the antagonistic relationship between magnesium and calcium drive muscle functions. Additionally, in my show, Magnesium Deficiency – Things Your Doctor May Not Know to Tell You, I share magnesium’s role as a master nutrient:

One of the little-known reasons that magnesium deficiency may be a contributing factor to such a variety of health issues is that this ‘Master Nutrient’ is utilized as an enzyme by a multitude of nutrients in a variety of cellular processes. Magnesium is such an important nutrient that taking it by itself, in many cases, actually raises blood levels of calcium, potassium, and Vitamin D.

I also say that:

While it’s fairly well known that magnesium is required for calcium to be absorbed in the intestinal tract, it’s less well known that magnesium helps calcium dissolve into solution in the bloodstream. (Natural calcium is an insoluble mineral.)


While magnesium is vital for the utilization of calcium, it also plays unique roles in the uptake of potassium and the transformation of Vitamin D. In the case of potassium, there are several studies showing that magnesium alone can improve low potassium levels.

Vitamin D, too, requires magnesium for several reasons. First, it’s needed in order to convert vitamin D into its active form in the bloodstream. You can be taking enough Vitamin D, but if you are magnesium deficient you may not be able to increase your blood levels.

How Do I Know I Am Magnesium Deficient?

I have listed 65 magnesium deficiencies in my eBook, Total Body Meltdown and the 65 Reasons Why. (You can click here for a free PDF of the eBook.) One way you can use the list of 65 magnesium deficiencies is to read them carefully and checkmark any that apply to your situation. For example, if you have restless legs and/or leg cramps every night (which I say in many of my articles and recordings is a sign of magnesium deficiency unless proven otherwise), you would place a check by that deficiency. Once you understand that your experience could very well be a magnesium deficiency and not a symptom of a health challenge, then the next step would be to self-experiment with magnesium. In the case of leg cramps, for example, you can try using ReMag Lotion. Slather your legs and feet at night with ReMag Lotion and see whether your cramps improve. When they do, then you’ll know you dealt with your magnesium deficiency.

How Much ReMag Should I Use?

The FDA regulates what we print on our labels. So, when you read the ReMag label, the suggested use is the maintenance dose of magnesium for people who are saturated (300 mg per day). By the way, that is their RDA for magnesium. If you want to saturate with magnesium because you are experiencing deficiencies, click here for my suggestions on how to use ReMag.

Just remember that your body will excrete whatever magnesium it can’t use. So, there is no “overdosing” on ReMag. Additionally, I’ve found that most customer’s saturation dose ranges between 2 and 4 teaspoons per day.

What’s Next?

Now that you understand that magnesium, calcium, Vitamin D and Vitamin K work synergistically and why, when, and how to supplement magnesium, I’ll talk about calcium in my next post. Please remember that my archives discuss these nutrients in depth. You can continue your research at:
