Magnesium Science


Cramps are a Result of Dehydration and Leaky Cell Membrane

Sport Cramps
When magnesium is lost excessively the cell membrane becomes compromised and ‘looser’ because the electrical charge drops.  That means the cell wall is not as good anymore at holding in electrolytes.  The membrane starts to lose integrity, potassium can leak out and the cell also loses water, leading to excessive dehydration.  This loosening effect also allows in more calcium and sodium, which are larger molecules. Some athletes have suffered cardiac arrest (heart muscle cramp) in the middle of a marathon when magnesium levels got critically low and too much water was lost.

Muscle RecoveryCalcium tightens and sodium stimulates, which starts a cascade of dehydration and the ‘squeezing’ effect we know as cramps, twitches, restless legs, (VIDEO) as well as the vascular constriction of hypertension.

Dehydration Increases With Low Intracellular Magnesium Status

When the body becomes dehydrated it moves to a water-conserving and rationing status.  It releases vasopressin – a hormone which constricts blood vessels so that more water is shunted to the brain, as the brain must take priority with water usage.  If the body is in a state of drought it will also message the kidneys to retain more sodium, which then retains more water and can lead to tissue swelling (oedema). In this state the proper elimination of toxins and wastes is diminished and can lead to septic conditions.  The best elecytrolyte balancing requires water and electrolytes (including sufficient magnesium)  to flush out wastes, allowing the kidneys and waste elimination system to return to normal.

The Magnesium Science of Calcium-Channel Blocking

Remember that magnesium is the best calcium-channel blocker – the natural controller of how the body uses calcium to its best advantage.  Calcium contracts the muscle fibres, but magnesium relaxes again by its rehydration and removal of calcium back to the extra-cellular spaces.

To help the body release this pressure and return to normal hydration drink more magnesium water – mixed as per instructions above. You can also add a small amount of sodium chloride salt if you have been perspiring a lot.  For fast relaxation massage into your muscles: Elektra Magnesium Cream plus extra sprays of Elektra Magnesium Oil Spritz (formula)Magnesium Charge Lotion can also help rapid muscle recovery.

ARTICLE: “The Extraordinary Power of Magnesium”
(as printed in Nexus Magazine Apr-May 2018)

Excerpts:  “Symptoms of low magnesium (hypomagnesaemia) may include tremor, agitation, muscle cramp, cardiac arrhythmia, hypokalaemia (potassium deficiency), chronic fatigue, numbness, tingling, seizures, excessive electricalactivity in the brain, sleep disturbance, bronchial spasms and asthma, allergic reactions, hyperactivity and ADHD, compromised immune response (over or under), as well as free calcium in blood causing hypertension and calcium precipitation, which results in ligament and vasculature hardening, fibroids and lumps. Associated diseases can include osteoporosis, metabolic syndrome, insulin-resistant diabetes, arteriosclerosis, skin disorders, lymph and kidney dysfunction, thyroid disease, cancer, anxiety and depression. As magnesium is also essential to synthesise RNA and DNA, low magnesium has even been found to be carcinogenic.5” …

“Asthma symptoms or anaphylaxis are also a sign of magnesium deficiency. An excessive immune response at the slightest provocation, resulting in uncontrollable chest spasms and tightening of airways can become debilitating, exhausting and in extreme cases fatal. Magnesium can calm down this reaction via a decrease in superoxide production, indicating that magnesium may modulate the inflammatory process and decrease release of free radicals.”

“The magnesium ion has an inhibitory action on smooth muscle contraction, on histamine release from mast cells and on acetylcholine release from cholinergic nerve terminals.”6  Low magnesium can also present as irregular heart beat with ventricular ‘mis-beats’ or subsequently atrial fibrillation. The left ventricle of the heart contains more magnesium receptor sites than other muscles and just like getting eye twitches or leg spasms when magnesium levels get too low, the heart muscle can develop spasms.”  READ MORE


Magnesium is Essential for Bone Health

Scientific studies show, “Positive associations between greater intakes of dietary magnesium and grip strength, indices of skeletal muscle mass, and BMD in men and women in middle and older age groups.” These studies suggest that magnesium supplementation may help with strategies to prevent sarcopenia, frailty, falls, and fractures.

Why is Magnesium so Important for Health?

Why is Transdermal Absorption Better?

Magnesium is now becoming a big revolution in natural health as industrialised societies suffer more and more under stress and are looking for ways to compensate without relying on drugs or surgery.  Transdermal absorption of magnesium salts is the best way to absorb magnesium, as no digestion of tablets is required.

Only a very small amount of oral magnesium tablets and powders gets digested and passes through the gut wall to the inner tissue areas of the body where it is mostly used. The majority of these oral magnesium supplements are expelled by the digestive system and can cause diarrhea.  Transdermal absorption is much more efficient and works more quickly with calming effects being felt within minutes of massaging into skin or soaking in a hot magnesium solution footsoak or bath.  It is using the same dermal pathways as sweating which releases electrolytes from the skin.  The skin is also capable of absorbing electrolytes back in as long as they are in the right form.  You can also do it by swimming in the ocean or bathing in mineral rich hot springs.

Massaging with Elektra Magnesium products delivers the magnesium and other elements and nutrients more conveniently to the skin.  From the skin (epidermis) the body takes up what it needs via the tiny capillaries of the dermis under the skin and is self-regulating.  It does not take up any more than it needs at one time (like tree roots taking up minerals from the soil).  Unlike drugs or herbs, you cannot overdose.  (Ref: Transdermal Magnesium Study Via Magnesium Cream).  It’s just nutrition provided to the largest organ of the body – the skin.  Feeding the body by feeding the skin makes a lot of sense… and feels sooooo good!

Why are Magnesium Chloride Flakes Better Than Oral Tablets and Powders?

Chloride is the most abundant negative ion in the body.  For us to be able to use the metals of magnesium, sodium, calcium, potassium etc, they are bound to chloride to be ionised and fully absorbed into the water molecule – and in a sense swallowed up by the water.  In that form (eg. magnesium chloride, sodium chloride etc) the electrolytes are biologically available.  Together, and as a solute in the water, these electrolytes conduct the bio-electricity of the body.

Mg Flakes
The ‘cation’ of magnesium in ‘magnesium chloride’ is bound up with chloride ‘anions’ so that the compound shares electrons in the outer shell to become stable.  It becomes easily soluble in water, and therefore more accessible to cells.
Magnesium ChlorideCompounds such as magnesium oxide that are much less soluble are therefore less accessible to cells.  Magnesium chloride however, once dissolved in water, gets access to cells without further digestion required.

Magnesium Chloride Hexahydrate is ideal because it is a compound of magnesium chloride bound up in a crystal matrix of six water molecules – hence the name ‘hexa-hydrate’.  This is the form that occurs in naturally dehydrated sea water after skimming off the sodium chloride part (to make table salt). The chemical notation is MgCl2.6H20.  The crystal salt flakes are usually 47-48% magnesium chloride, 1-2% other sea trace minerals, with the other half of the flakes being crystalized water.
magnesium chloride hexahydrate

This is why the flakes are so hygroscopic – that is, their ‘charge’ attracts water from the atmosphere and they can start to ‘sweat’ and become sticky if there are humid conditions and they are exposed to air.  If left out long enough, they will become fully saturated with the water and turn back into the liquid magnesium salt solution called ‘magnesium oil’ (which came from the brine that came from the sea water).  The magnesium chloride in crystalized or liquid form, just contains less or more water in its different states.

When you take oral tablets and powders of various magnesium compounds (magnesium joined to another element), they have to be digested in the stomach using hydrochloric acid.  The older we get the less stomach acid we make and the more difficult it gets to digest.  Also, after the body separates the magnesium from the other element/s in the compound and the tablet’s fillers and binders, it joins the magnesium molecule to chloride for solubility and access to cells.

All this takes a lot of extra time before you feel the benefit of the magnesium. By the time it can get through the bowel wall several hours later it is a much smaller quantity that is available for cells than if you soaked in magnesium chloride solution (magnesium flakes in water) or applied it to the skin as a magnesium skin care product.

The gut wall can only take up a small dilution of magnesium – such as what would be in spring water or foods.  Higher concentrations are eliminated via the digestive system.  Scientists have found that, “the absorption of magnesium decreased with increasing magnesium concentrations.”  This is why high concentrations in oral supplements tend to be wasted so much.

When you take too much magnesium supplement orally the bowel contents become loose and watery, finding their way into the toilet well before you get the benefit of all that magnesium.  Via the skin there is no digestion required because the magnesium chloride solution is already in the right form for cellular uptake. You can feel the benefit of the magnesium much sooner and absorb a higher quantity. Remember, the body takes what it needs, but no more – just like the tree roots take up minerals from the soil but no more than the tree needs at any one time.  It is naturally self-regulating.

Magnesium Bioavailability in Drinking Water

Magnesium bioavailability from mineral waters with different mineralization levels in comparison to bread and a supplement (2017)

“The results of serum and urine analysis indicated that Mg bioavailability was comparable for mineral waters with different mineralization levels, bread, and a dietary supplement. Specifically, Mg bioavailability was not influenced by the presence of SO4, HCO3,− or calcium. Thus, mineral water with higher concentrations of Mg constitutes a calorie-free Mg source that contributes to optimal Mg supply. [AND]…Multiple portions consumed throughout the day may increase Mg bioavailability.”

Magnesium bioavailability from mineral water. A study in adult men (2002)

The fractional absorption rate is high at low Mg load and decreases exponentially with increasing carrier amounts. Several authors have outlined that higher bioavailability is observed when a given amount of Mg is distributed over a day rather than being consumed in a single bolus (Schuette et al, 1990; Fine et al, 1991; Lo¨nnerdal, 1995); consequently a regular water intake distributed throughout the day would be expected to lead to a higher absorption.”

Influence of the consumption pattern of magnesium from magnesium-rich mineral water on magnesium bioavailability (2011)

“Thus, one simple means of increasing Mg absorption and retention of a given daily intake of Mg is to divide the daily dose into smaller increments taken at equally spaced intervals  throughout the day. In terms of supplementation, this may result either in a more rapid  repletion of body pools when deficiency or sub-deficiency occurs, or in a better prevention  of the appearance of a sub-deficiency. Using this consumption pattern, Mg-rich mineral water delivers Mg more efficiently to the body. Further studies are required to confirm these results with Mg-rich foods or food supplements.”

Intestinal Absorption and Factors Influencing Bioavailability of Magnesium – An Update (2017)

“Mg2+ is absorbed via a paracellular passive and a transcellular active pathway that involves TRPM6/7 channel proteins. The bioavailability of Mg2+ varies within a broad range, depending on the dose, the food matrix, and enhancing and inhibiting factors. Dietary factors impairing Mg2+ uptake include high doses of other minerals, partly fermentable fibres (e.g., hemicellulose), non-fermentable fibres (e.g., cellulose, lignin), phytate and oxalate, whereas proteins, medium-chain-triglycerides, and low- or indigestible carbohydrates (e.g., resistant starch, oligosaccharides, inulin, mannitol and lactulose) enhance Mg2+ uptake. The Mg2+ dose is a major factor controlling the amount of Mg2+ absorbed. In principle, the relative Mg2+ uptake is higher when the mineral is ingested in multiple low doses throughout the day compared to a single, large intake of Mg2+

Comparative study of magnesium salts bioavailability in rats fed a magnesium-deficient diet (2010)

“Mg chloride showed the highest efficiency among inorganic magnesium salts. “

Bioavailability of US Commercial Magnesium Preparations (2001)

“The low fractional absorption we observed for magnesium oxide (4 percent) is identical to that observed in prior studies of magnesium sulphate bioavailability… Results indicated significantly higher… bioavailability of magnesium chloride.”

Your health should always come first, so you should only rely on trustworthy suppliers to buy magnesium oil in Australia. This nutrient can benefit your immune system, which can help you stay healthy against infections and inflammation. For those who struggle with sensitivity to other magnesium supplements, you should consider our special formula magnesium oil spritz as a gentler (but very powerful way) way to get the magnesium nutrition you need.

Benefits of Magnesium Oil in Australia 

There are many benefits to transdermal magnesium when you apply it regularly. These benefits include:
  • Addressing magnesium deficiencies, which can cause metabolic syndrome, inflammation, headaches, chronic fatigue, gut issues, skin problems, cramps or restless legs, heightened allergies, hypertension, and disturbed sleep. If you experience any of these issues and don’t get enough magnesium, then our magnesium oil spritz may help you resolve them.
  • Bypassing the digestive system:  Dietary magnesium supplements can be hard to digest and absorb, and can even cause diarrhea. You can however apply magnesium oil spritz directly to your skin for fast and efficient results by taking advantage of the fact that your skin is a natural nutrient reservoir and can absorb the magnesium directly as magnesium chloride salt (electrolyte). The body can thus absorb large amounts of magnesium more effectively, rather than letting much of it pass unused and wasted via the digestive tract.
  • Hospitals sometimes use injected magnesium in the case of severe and critical magnesium deficiency.  It can save your life.  However, why let the deficiency get so bad that you need an invasive procedure like this?  Magnesium oil spritz offers an easy way to top-up daily and to maintain a healthy magnesium balance.  You can also spray on our magnesium oil spritz at home any time you want to, and in any amount as needed, to help relax and recover.
When you buy our special magnesium oil formula, you have access to a convenient, skin-friendly, pain-free, and easy way to get natural magnesium into you for optimal health and wellness.
