Magnesium

Why do we need magnesium?

Magnesium is one of the most abundant minerals in the body, with about 25g being present for normal functioning. It is vital for normal bone and tooth growth and is involved in a wide range of biochemical reactions, ranging from protein synthesis to blood pressure regulation and muscle contraction.

The benefits of magnesium in healing wounds were first observed in cows in 1619. It is now commonly used in dealing with aches and pains, particularly muscle cramping and restless leg syndrome.

Magnesium has also been found to have effects on the nervous system, reducing symptoms of muscle spasms and twitches. The relaxation effects it has on muscles are also seen to affect mood, reducing symptoms of anxiety and promoting good sleep.

Natural sources of magnesium

The current recommended daily allowance of magnesium is 300mg, though many health professionals believe that this level is too low, and at least double should be consumed daily.

Magnesium is available naturally in many food sources, such a leafy green vegetables and fibrous foods. However, the amount of magnesium in foods has greatly depleted over the last hundred years with increased use of herbicides blocking the uptake of minerals in many foods.

Food source Magnesium content (milligrams, mg)
Pumpkin seeds, 50g 267
Mackerel, 100g 97
Spinach, 100g 79
Fig, 100g 68
Brown rice, 100g 44
Quinoa, 100g 37.6
Avocado, 100g 29
Banana, 100g 27

 

Magnesium deficiency

Magnesium deficiency is a far more common problem than many people realise, and a wide range of mild symptoms can often be traced back to this deficiency. It can be difficult to measure levels of magnesium as over half the magnesium is stored in the bones, and only 1% of magnesium is distributed in the blood, making blood tests for the condition not very useful.

Symptoms of magnesium deficiency tend to be mild and not specific to the condition, making it difficult to diagnose. Muscle spasms and cramps are common physical symptoms, developing into muscle weakness and impaired muscle co-ordination. Headaches and migraines are also often found to be linked with depleted levels of magnesium. Emotional symptoms include fatigue, low mood and attention disorders.

Magnesium deficiency is particularly common among menopausal women, or those who experience symptoms of PMS. This is because hormonal changes can cause the body to excrete more magnesium than normal. Woman often find that simply restoring an adequate level of magnesium dramatically improves their PMS or menopause symptoms.

Too much magnesium

Overdosing on magnesium through natural dietary sources is difficult as the kidneys naturally filter excess magnesium out of the blood. However, it is more likely if taking too many dietary supplements, particularly if already suffering from impaired renal function. Symptoms of magnesium toxicity would usually begin with an upset stomach, nausea or diarrhoea. This could develop into a drop in blood pressure, slowed heart rate and difficulty breathing.

      Hi Lesley, a magnesium spray would be better absorbed than an oral supplement as the mineral gets delivered straight to your bloodstream, however, the dose of magnesium can vary from brand to brand. The minimum amount you should be getting each day is around 300mg so hopefully this gives you an idea as to whether to product you are using is supplying you with an adequate amount of magnesium. As I mentioned, overdosing on magnesium is difficult, but given your health complaints, it might be worth speaking to you doctor to get an idea about how much magnesium you, as an individual, should be getting.
