"The wish for healing has always been the half for health"
Lucius Annaeus Seneca

Magnesium is essential for calcium absorption.

Magnesium, the essential mineral to calcium uptake

I have often found with Hair Mineral Analysis that the patient presents with calcium levels that exceed the highest range of the chart. This indicator shows that they have levels of circulating calcium in their blood but that they have an impediment to absorbing it. This revelation always comes as a shock, because most people on an average Western diet, pride themselves on getting enough calcium which they know to be good for them. It is good for them, but only when it is absorbed, otherwise it becomes an excess and causes many health issues like osteo-arthritis, fatigue, depression, loss of appetite, increased thirst and need to urinate, kidney stones and so on.

A simple addition of magnesium to the diet can alleviate many or all of these problems. Since it's become increasing difficult to get magnesium through the food that we eat, it might mean taking a supplement every day.

How would you know if you have a magnesium deficiency?

The first symptoms of magnesium deficiency can be subtle. Most magnesium is stored in the tissues, so leg cramps, foot pain or muscle ‘twitches’ are usually the first signs. Insomnia, migraine headaches are also very common magnesium deficiency symptoms. 

Magnesium is one of the most important minerals in the human body and is essential to good health. It is critical in over 350 essential biochemical reactions in the body including digestion, energy production, muscle function, bone formation, creation of new cells, activation of B vitamins, relaxation of muscles, and also assists in the proper functioning of the heart, kidneys, adrenals, brain and nervous system.

In fact, Magnesium is the fourth most abundant mineral in the body—it can be found in human bones, teeth and red blood cells, and activates more enzyme systems than both Iron and Zinc combined

A surplus of calcium in the blood can also be a sign that the parathyroids are not functioning well, a condition known as hyperparathyroidism. This happens when the tiny glands in the thyroid secrete too much hormone and may be caused by a benign tumor called an adenoma forming on one of the parathyroid glands, causing it to become overactive. Benign tumors are noncancerous, fortunately, but this should be checked if there is any doubt.

What is so sad is that on many web sites with a medical background or influence, the reason for hyperparathyroidism is given as 'not known'.

A chronic magnesium deficiency is never suggested as the possible cause.
