Magnesium is as essential to us as air.
If you are depleted in magnesium your body responds with many different symptoms. Some of the major ones are heart disease, diabetes, osteoporosis, arthritis, insomnia, anxiety and endocrine imbalances.
You get magnesium from your food. The argument is that our food sources and dietary choices are so depleted in magnesium that people don't get enough.
For myself I feel these explanations and theories evolve and develop as people research more. I am more interested in results.
Magnesium is used in large doses in emergency situations for heart attacks. It causes the heart muscle and vascular system to stop spasming and to start to function regularly. Supplementing with magnesium can prevent heart disease and stop palpitations.
Magnesium is necessary for the production and transport of hormones in the body including insulin, cholesterol (you do need it) and estrogen and testosterone.
Magnesium is necessary for the absorption and management of Calcium in the body. If you do not have enough magnesium, calcium will leech out of your bones.
The list goes on.
My personal story has been that daily use of magnesium has cleared my psoriasis (a persistent problem I have had for several years) and also the fine lines on my face.
Try transdermal magnesium and prevent (or treat) serious illness.
You cannot overdose on magnesium. Excess magnesium will be excreted via your kidney (unless you have kidney diease).
Best wishes in health
