Magnesium Deficiency & Fatal Arrhythmias: Two Videos with Dr. Carolyn Dean
Mineral deficiencies like magnesium (Mg) can force the heart into fatal arrhythmias. Magnesium is one of the most common nutritional deficiencies. It’s chronically lacking in most diets. Almost everyone with A-Fib is magnesium deficient.
Two Videos About Magnesium Deficiency with Dr. Dean

C. Dean, MD
We have two videos in our A-Fib Video Library featuring Dr. Carolyn Dean, author of The Magnesium Miracle, talking about magnesium deficiency and calcium overload:
“The Best Way to Supplement Magnesium” with Dr. Carolyn Dean. Getting nutrients through food is not always possible; discusses side effects of too much Mg and how you can tell if you have a deficiency.(3:39) Go to video.
“Importance of Balancing Calcium & Magnesium”. Dr. Dean discusses the importance of balancing your intake of magnesium and calcium (2:1); the benefits of both and why you need to have both in the body; the problem of ‘calcium overload’. (2:30) Go to video.
Should You Take Magnesium Supplements?
As Dr. Carolyn Dean states, it’s hard to get enough magnesium from today’s food. Magnesium has been depleted from the soil by industrial scale farming. Therefore, A-Fib patients should consider taking magnesium supplements. (Note: it takes about 6 months of magnesium supplements to build up healthy level of Mg.)
For more about magnesium, see my article: Cardiovascular Benefits of Magnesium: Insights for Atrial Fibrillation Patients.
