Using Transdermal Magnesium

Posted on 16 January 2017 by Leonie Satori

Magnesium is a critical nutrient for cellular health and energy manufacture and using transdermal magnesium is one of the best ways to increase levels of this essential nutrient.

Using Transdermal Magnesium

One of our most readily depleted electrolytes, magnesium, like potassium, sodium and calcium is excreted when we sweat, it can be affected by pharmaceutical medications, coffee and alcohol and is readily depleted from foods with processing. Magnesium is absorbed through the walls of the small intestines and concentrated in the bones, teeth, muscle, liver and pancreas. 

Magnesium is a co-factor for many enzymatic reactions in the body, it is required for cellular energy manufacture, works with calcium for muscle relaxation after exercise, nourishes the nervous system and plays a role in blood sugar regulation. With these far-reaching uses in the body, it makes sense that supplementation through oral or topical magnesium may be necessary to replenish magnesium levels.

How Do I Know If I am Magnesium Deficient?

It is estimated that approximately 49%* of the population is at risk of being magnesium deficient. Genetics, lifestyle and digestive capacity can influence the risks of being deficient in this essential nutrient, however, for most people deficiency presents itself in muscular complaints. Cramps, muscular spasms or twitches and restless legs are common in those with magnesium deficiency as are pain, inflammation of the joints or arthritic symptoms. Magnesium deficiency may also present as lethargy, sugar cravings, irritability, anxiety or nervousness. Those on pharmaceutical medications, using excessive amounts of coffee, alcohol or with ongoing digestive complains may also be at risk of magnesium deficiency.

What is Transdermal Magnesium?

Composed of magnesium chloride from natural salt lakes, transdermal magnesium provides a vehicle for administering magnesium in the form of concentrated and readily absorbed magnesium. Transdermal magnesium is a form of magnesium that is used directly onto the skin, rather than taken orally in a powder or tablet, it is most often in the form of an oil or spray, gel, cream or bath flakes. Transdermal magnesium therapy involves using one of these topical applications to ensure rapid absorption of magnesium through the skin or dermis.

How is Transdermal Magnesium Different to Oral Magnesium Supplementation?

Oral magnesium supplementation with tablets or powder is beneficial for many individuals and is often excellent to use in conjunction with transdermal magnesium, however there may be some situations where topical application of magnesium is preferable. Transdermal magnesium offers rapid absorption through the skin, and often to the tissues where it is required - muscles. Bypassing the impediments of digestive processes, transdermal magnesium offers faster results where acute symptoms require immediate action. Also if malabsorption, digestive issues or medications inhibit proper absorption of magnesium through oral administration, transdermal magnesium is an ideal and often safer alternative.

Who Would Benefit From Transdermal Magnesium?

Exercise, hot weather and excessive sweating can rapidly deplete our magnesium stores, so those living in hot climates, labourers and anyone who exercises would benefit from transdermal magnesium. Those with digestive issues, especially those with diarrhoea or absorption problems may find transdermal magnesium more effective than oral dosing. Those with sugar cravings, mood swings, a stressful, busy life, a nervous tummy or anxiety may find transdermal magnesium beneficial.

How Do I Use Transdermal Magnesium?

Many transdermal magnesium manufacturers offer a variety of applications. A little different to epsom salts, which are made of magnesium sulphate, magnesium bath flakes provide whole body absorption of magnesium chloride over a larger area of skin. Excellent after a day in the sun, a big workout at the gym, magnesium bath flakes provide the most relaxing application of transdermal magnesium.

More concentrated topical magnesium products such as gels or oil sprays provide a practical and easy application of magnesium. Personal preferences may dictate the vehicle for administration, but magnesium oil spray is the most popular. Technically not an oil, magnesium oil sprays can feel a little like an oil on application. Rapid absorption makes these an ideal late-at-night remedy for cramps, spasms or restless legs. Magnesium gels are slightly thicker on application and tend to stay on the skin for a little longer than just the spray. A magnesium gel is also suitable for those who feel a stinging sensation when using the spray or oil on its own. A good at-home remedy for cramps or restless legs, transdermal magnesium oil spray or gel may be applied to the area affected which, in most cases is the legs.
