Different ways of applying transdermal magnesium chloride using magnesium chloride flakes/crystals or magnesium chloride oil (MCO)

IMPORTANT: Read ALL instructions before applying magnesium chloride oil

Apply MCO to skin and rub in


Bathtub soak  (necessary to raise body's magnesium levels quickly in cases of serious deficiency)

General information on transdermal treatments

Transdermal applications very effectively enter the body through the skin

▲ Delivers medication directly to the site of injury, pain or disease

▲  Enters the blood stream to increase the body's stores of whatever substance is being applied

Introduction to transdermal magnesium chloride oil (MCO)

Magnesium chloride is the dried liquid remaining after sodium chloride has been removed from sea water.   Technically called magnesium chloride hexahydrate, its chemical formula is MgCl2.6H2O. Common names are Nigari and Bittern.

Transdermal MCO is more effective and faster-acting than oral supplementation.   The biggest advantage of transdermal magnesium delivery is that the intestines are not adversely impacted by large doses of oral magnesium, which has a potentially laxative effect. Also magnesium absorption issues are avoided by by-passing the stomach and liver. and digestive problems affecting many people.

Most specifically, the magnesium chloride molecule has its magnesium ion loosely bonded to its 2 chlorine atoms  (magnesium chloride has a stability constant of 0), such that its magnesium ion can easily break away for use in cells and tissues;

Transdermal MCO is the application of a solution of magnesium chloride oil to the skin to provide a remedy for a multitude of health problems resulting from magnesium deficiency - including stress, heart disease, cancer, diabetes, arthritis, fibromyalgia, migraines, aches and pains.

Other health benefits of transdermal MCO include:  greater energy, more relaxed muscles, stronger connective tissue, better sleep, improved mental function, reduction/elimination of headaches, arterial health, better hormonal balance for men and women (including better reproductive function, reduced PMS). Magnesium maintains the flexibility of cell membranes for greater uptake of bioactive substances (e.g., nutrients, neurotransmitters, and hormones) and detoxification of toxins and metabolic waste products. Magnesium chloride acts as a full body tonic.

Functions of Magnesium in the body

The Many Health Benefits of Magnesium

Why are we Mg-Deficient?

Transdermal MCO is an effective way to quickly raise body's magnesium stores.    Magnesium in a solution of MCO finds its way through the skin and into the blood stream. From there magnesium can be delivered to needy body cells/tissues. Covering a large area of skin or taking a footbath or especially a full immersion bath will swiftly correct a deficiency in blood magnesium levels.

When taken transdermally for as a daily magnesium supplement, you don't need as much magnesium as when taken orally - since transdermal magnesium is more bioavailable. A good rule of thumb is to halve the amounts recommended for oral supplementation

How much magnesium in magnesium Chloride Oil (MCO)?

One teaspoon of 35% strength MCO contains ~600 mg of elemental magnesium

(1 teaspoon of 33% strength MCO (Ancient Minerals™Mg Oil strength) contains 560 mg of elemental magnesium)

How to make magnesium oil

Transdermal MCO directly raises magnesium levels in specific localized tissues - for the relief of aches, pain, soreness, infection, burns, etc. Localized application is particularly useful for relieving the pain of sore muscles and joints related to magnesium deficiency.

Example uses of transdermal magnesium chloride

Aching/Sore muscles - apply an MCO pack to area and if problem is chronic also use the footbath method.

Cancer - use the footbath regimen in conjuction with rubbing on skin for 2 months to normalize body's magnesium levels, which are usually found depleted in cancer patients. Chemotherapy also further depletes magnesium levels

Fibromyalgia - magnesium deficiency is almost always the root cause of this painful problem.

Acne, eczema, psoriasis or to rejuvenate/moisturize your facial skin - apply diluted MCO to the face. You may get some initial irritation/inflammatory reaction - experienced as redness, rash or heat as the magnesium goes to work. Don't go past your comfort level, just dilute the oil some more, even if it takes longer to attain successful results. Also, you can always wash it off with water if you need to. However, once the magnesium has dealt with the problems (after about a week or so of daily application), you may even be able to apply the oil full strength with no more reaction.

Wounds - MCO is best used as a 4% solution, that is 4 g (a level teaspoon) Magnesium Chloride flakes in 100 ml (about a 4oz glass) of water.


Personal care uses

•  Natural deodorant - dab into armpits using fingers or a 100% cotton ball. Dilute as needed, or it may sting (especially if you have recently shaved)

•  Toothpaste

•  Mouthwash

•  Deodorant

•  Hair conditioner

MgCl2: Possible Counter Indications and Warnings

TOO MUCH magnesium can cause muscle weakness, decreased reflexes and disordered cardiac rhythm.    If this happens temporarily use more calcium. Having said this, it is unlikely that the use of transdermal magnesium could cause a problem with an overdose, any more than would regularly swimming in the ocean.

If someone has kidney failure or is on a dialysis machine, excess magnesium will build up because it will not be eliminated in the urine. Magnesium supplementation should NOT be attempted without medical supervision

TOO MUCH magnesium can cause muscle weakness, decreased reflexes and disordered cardiac rhythm.  If this happens temporarily use more calcium. Having said this, it is unlikely that the use of transdermal magnesium could cause a problem with an overdose, any more than would regularly swimming in the ocean.

Those with an excessively slow heart rate

Those with myasthenia gravis (rare chronic autoimmune disease causing muscle weakness)

Those with severe adrenal weakness or low blood pressure need to be careful.      Those with low blood pressure usually require extra calcium in addition to magnesium.   Normal blood pressure is about 120/80; the lower it is, the higher the need for daily calcium supplementation. While those with high blood pressure benefit from ingesting twice as much magnesium as calcium, those with low blood pressure may take twice as much calcium as magnesium, but both in relatively high amounts. Those with low blood pressure and inflammatory tendencies should also significantly reduce their phosphorus intake, since a high levels of phosphorus in the body tends to deplete magnesium and calcium
