What is “Zechstein Inside®” Transdermal Magnesium Spray Therapy

In the modern industrial world, the open sea is unfortunately more polluted than ever. The need to find a source of pure magnesium far removed from our present pollution in order to regain a therapeutic effect and proper detoxification, is growing exponentially.

One of the most effective ways to overcome magnesium deficiency caused by a depleted soil has come about through the discovery of the Zechstein Sea and Zechstein Inside® transdermal magnesium spray. Our ancestors had mineral-rich soils and used magnesium-rich compost, and yet they often went through great efforts to bathe in waters saturated with diverse minerals through the thalassotherapy and thermal cure culture of Ancient Greece and Rome. Our ancestors understood the magnesian mystery: good circulation and proper detoxification is greatly assisted by the simple act of saturating the skin with pure magnesium spray with its naturally occurring oligo-elements found in the sea.

Our Transdermal Magnesium Spray Comes from the Ancient Zechstein Sea.

Coming directly from an ancient sea located 1.6km (1 mile) underground dating back 250 million years and completely removed from atmospheric pollution, it is the purest source of magnesium on Earth by certification. It’s not just a product, but a unique story and gift of nature. The texture of transdermal magnesium spray is similar to that of a dry oil. The Zechstein Inside® unique extraction process is never heated or refined and it is bottled in its raw, natural state without the need for chemical purification, which is the industry standard for magnesium chloride. It’s all about the source. From unique mineral deposit layers found under the Netherlands this “white gold”, as they call it in Holland, is of the highest quality. We let nature do the purification for us over 250 million years leaving a raw state, pure transdermal magnesium spray as a final product.


Always Verify the Source!

“Natural and Pure” or even the word “Zechstein” is not a guarantee without the Zechstein Inside® logo. 80% of magnesium is imported from Asia where it is chemically purified and refined in difficult working conditions for export as magnesium oil. Even companies that source their products from the open sea or salt lakes must chemically “upgrade” them to clean out heavy metals and contaminants. These products are often less expensive and are sold in plastic bottles. Our unique pure magnesium chloride layers from the crystallised Zechstein Sea underneath the Netherlands are without comparison. This is the only transdermal magnesium spray to be studied for the elimination of heavy metals in the human body. Purity is the key.

Our Unique Extraction Process :
Spring Water

Our extraction process only uses spring water, which has been certified by high purity standards, to dissolve the magnesium salt layers. We offer total transparency. Anyone may call the source in the Netherlands to verify the origin and purity. This in and of itself is a rarity on the magnesium spray market as well as the magnesium pill market.

For us, there is no need to separate the magnesium from other minerals or contaminants because the rock strata is pure magnesium. The scientific name of pure magnesium chloride in the natural state, i.e. in stratum form, is bischofite. The higher the bischofite quality (its concentration of pure magnesium chloride), the greater the purity of the magnesium spray oil. Magnesium spray oil is not difficult to recreate or “upgrade” by chemical processes using industrial potassium mining “derivative magnesium” but in Holland it is found in a pure state where the Zechstein Sea is found. The marketing “Zechstein” can be used to falsely advertise as this word cannot be protected by law but the “Zechstein Inside®” logo is a sure bet as far as its origin and extraction is concerned. Layers and layers of abundant stratum result from a natural purification within the earth. When the source is pure, no transformation is needed.


What is unique about our products?

Our products are directly from the original European source in Veendam, Holland. Most brands will never tell you the actual location or city where they obtain their magnesium as 80% of magnesium extraction is done in Asia (China, Tibet, Mongolia)  and is re-marketed to hide this fact using self-certified, off-site certificates. Why is it that the biggest brands on the American market have not been able to provide a verifiable (by a simple phone call at the source) and current “certificate of origin” when asked by consumers who have subsequently revealed this to us? This includes the most popular and trendy brands.  Many dishonest brands deem this information as secret or proprietary. We feel this is a lack of transparency. To their credit, they may have been undiscerning by purchasing solvent treated magnesium or industrial grade magnesium from dealers who falsely claim the Netherlands as the origin, going so far as to use laboratories in the Netherlands to provide their certificate of analysis (but not origin) for their mailed-in samples. The term ‘Zechstein’ cannot be protected by law. Only the trademark Zechstein Inside® can guarantee the origin and purity.

We obtain our magnesium from the #1 Doctor recommended source in Europe, the home of the Zechstein Sea. Our products are sold in over 1000 stores in France and Switzerland.

No dilution. We use maximum concentration, which gives the product a molecular weight which increases absorption.  Our products have no carrier oil. Magnesium chloride has a natural viscosity and feels like a dry oil. Many brands dilute their products with added water without telling you.

We use only 100% unrefined Zechstein Inside ® raw-state magnesium spray (or magnesium oil). We do not cut our quality magnesium with cheaper, processed magnesium. Many brands mix low-quality and high-quality magnesium together to save money as they expand yet still retain their original marketing claims. This ‘mixing’ changes the product significantly. However, the majority use a generic industrial grade magnesium spray from the start, which is chemically treated with solvents. We do not add ingredients in order to trademark and have control over our products. We do not feel that aloe vera or other ingredients help magnesium chloride in cellular transport functions, to pick one example.

We use original blue HEALTHY GLASS bottles. 95% of the market uses soft plastic containers which leak endocrine disrupters (BPA and the newly discovered danger BPS) into the final product all the while polluting the environment. Our caps are BPA, DEHP, PVC and phtalate-free.

We do not refine, upgrade or chemically treat our magnesium spray. 100% RAW state. Magnesium flakes are a secondary product which are created by heating the raw oil to over 300 degrees, creating hydrochloric acid in the process. And although they may be a good addition to improve our infected bath water or  for light detoxification, they cannot substitute for the primary product. A high percentage of brands use derivative magnesium from potassium mining operations and most chemically treat with solvents to purify contaminants before sale. We let nature purify our products over 250 million years.

Why does molecular purity matter?

Detoxification is the key to full spectrum magnesium spray application. Magnesium is responsible for hundreds of vital functions in the body. One major role it plays is to heal the nervous system, but there are also many studies on magnesium’s role in magnesium-dependent, enzyme-assisted chelation. Magnesium chelates toxins, heavy metals and even EDCs (endocrine disrupting chemicals). These toxins are then excreted through transpiration, among other channels. There are many studies on magnesium and chelation, and concomitantly, its role in detoxification. When the magnesium spray is pure and unrefined it retains 100% of  its chelation properties. Being molecularly unencumbered by other elements it is “stickier”, meaning it can chelate toxins better at the cellular level. Cramps, for example, come from toxins or acid residues in the tissues that are finally removed by the magnesium chelation and Mg/Potassium pump system. So pure magnesium spray in pure glass, keeps our magnesium active, uncontaminated and ready to assist in removing toxins from the body. On top of that, it addresses magnesium deficiency as well. Full Spectrum!

Why do glass containers matter?

Magnesium is involved in cell membrane transport. Magnesium contains the “keys and locks” to and from the cellular sanctuary! Therefore a magnesium molecule that is contaminated with plastic compounds delivers these compounds directly to the cell.

There is a high probability of the following adverse effects associated with phthalate absorption, even at low doses:

 Toxic to the brain and nervous system
 Appearance of cancer
 Male fertility problems.
 Alteration in the functioning of the thyroid.
 Insulin resistance development
Decreased urogenital distance in newborns
Promotes weight gain at the abdominal level
 Favors the appearance of allergic rhinitis and asthma
 Reduced mobility of sperm cells
 Toxic to the respiratory system
 DNA mutagenic effect
 An early appearance of puberty in young girls
 Increases the risk of premature births

The softer the plastic, the more potential it has to leach into the final product.  User-end packaging is always made from soft-plastics. These plastics come into contact with the product and can contaminate the product, making it less effective in removing these same endocrine disrupting chemicals from the body, which is an important part of why we detox in the first place. Perfection may not be possible here in our polluted world but, as these toxins are cumulative, we seek to reduce as much as possible our daily exposure. Plastic compounds come into contact with heat, halogen lighting radiation and oxygen, all of which degrade the plastic compounds. Not only on the shelf but as we use them.

Many suppliers of food grade olive oils, to pick one example, which ship in large hard-plastic tubs have begun to realize that hermetically sealed, low-oxygen hard-plastic tubs, which are only used for 1 to 2 week-long boat transport, can reduce greatly any leaching effect caused by transport. If they were to then pour this same olive oil into esthetically oriented, user-end soft plastics exposing all of the surface area of the oil to soft-plastic which will itself be exposed to halogen radiation, heat and oxygen, they would successfully contaminate their products–increasing by more than 500% the exposure and thus the rate of leaching. That is why they use glass bottles for quality olive oil. We keep our distance from leaching plastics. Our magnesium spray products are bottled in glass using only food grade (LFGB certified) silicone tubing.

Glass is healthy and is making a comeback! It is also 100% recyclable and therefore the most ecological and esthetic choice.

For More Information

European “Certificate of Origin” (Netherlands). Guaranteed traceability. A truly controlled certificate of origin is an essential document but nothing is comparable to the fact that you can contact the source directly to check the quality and the origin.


 Unique source the world over. Our products do not come from the open and polluted seas. They are not exposed to the plethora of chemicals, radioactivity or pollution of our modern oceans. Even thalassotherapies, natural thermal baths and spa waters are tainted to some degree unfortunately. Originating from an ancient sea, this geological stratum of pure magnesium chloride in the form of pure bischofite layers, which are rare at this level of purity, yet found in abundance underneath the Netherlands, date back 250 million years, without any contamination from the outside.

Be attentive : The marketing “100% natural” does not guarantee anything. 80% of the world’s magnesium comes from Asia, mostly from the Qaidam industrial basin in China, which is located on the “Qinghai-Tibet” plateau, where asbestos and gas are also extracted. Also be wary of generic products, even those from local coastlines or open seas because in order to make magnesium oil with sea or inland salt water brine, one will need to concentrate the mineral salts which concentrates the pollution and heavy metals into the brine. Dead Sea and Salt Lake minerals have high levels of bromine and mercury, respectively. Making it necessary to go through thermal or chemical processes in order to “clean”, “upgrade” or separate the magnesium from contaminants. These products undergo consequent transformations. Losing their RAW, unadulterated qualities. For us, purity is the key to detoxification.These generic products are often cheaper. But knowing it costs only 20-60 euros per year to do a full course of treatment with our products, its wise to find the best quality you can for such an important and prevalent mineral deficiency

 Ecological extraction by solution using only natural local spring water to dissolve the pure magnesium chloride salt layers. No need to separate the magnesium from other components, as is the case for all other sources, because the stratum is pure magnesium chloride. Local spring water is also analyzed to ensure its purity. Certified by Zechstein Inside® (Netherlands). Total transparency. Just call the source in the Netherlands. No transformation or refining. We let nature filter, clean and purify the crystals of magnesium for us over 250 million years.


Be attentive : Always be vigilant as to the mode of extraction of magnesium. Words such as “unrefined” or “pure” can be empty phrases. The truth is that chemical purification and “upgrading” (for the separation of potassium and heavy metals) are the established practice in the industry. The word “Zechstein” cannot be legally protected and is often used to eclipse the true origin of the product, which is not the case for the Transdermal Magnesium certified “Zechstein Inside®”. Without the “Zechstein Inside®” logo, chemical purification is the norm. Our extraction is unique in the world. Words such as “Genuine” or “Authentic“ Zechstein without the “Zechstein Inside” logo may be using the word Zechstein abusively. Ask if you can call their actual source (extraction site). Some areas of the Zechstein Sea have been used for potassium mining, and they have industrial magnesium as a byproduct. We do not recommend these products as they have been chemically purified or “upgraded” to remove heavy metals and other minerals and do not come from pure natural state magnesium layers.

 Source protected 1 mile underground. The sea has crystallised into a soft stone, an abundant geological stratum, an ancient sea of 250,000 years, the Zechstein Sea. A unique story. “White Gold” underneath the feet of Europe.


 Far removed from all atmospheric pollution. Zechstein is known for its molecular purity by comparison, line by line, with other forms of magnesium on the market. And it is the only one to be studied scientifically for the elimination of heavy metals in the human body (EJNR, Joslin / Watkins).

 Always sold in noble blue glass, without phthalates or endocrine disrupters found in soft plastics. Our pumps are guaranteed without bisphenols, BPA, DEHP, or PVC. The only way to avoid the contamination of phthalates is to buy glass bottles.

 Surface area of 1 million km2. More than 1000 years of pure magnesium for the World.

Why is the source so important?
Magnesium is all the same right?


There is a reason why nearly ALL the major brands do not give out detailed and current source information with the actual city of origin/phone numbers etc. Most of the industry uses a less expensive industrial grade magnesium which is used for de-icing planes in order to create their supplements, oils and magnesium spray. This industrial grade magnesium is sent to the US daily by big companies and aerospace industries so repurposing it for supplements or topicals is much cheaper as one does not have to pay much for shipping fees. Who wants to order from Europe when China provides 85% of the worlds magnesium for much cheaper? China will even sell these products to US brands with a host of magnesium creams and lotions in cheap plastics as if they were Zechstein using Ancient, Permian or even Zechstein marketing claims.

It is a strong temptation to have China bottle, label and supply the magnesium as this saves lots of money as one no longer has to ship from different sources, like Holland, and bottle when they can do it all for you. Anyone can chemically “upgrade” undiscerning strata from the Salt Lakes (with high mercury), the Dead Sea (with high bromine) or even from Tibetan exploitation to create all sorts of generic products via solvents and chemicals but what we are after is a naturally made, not man made, purity. That makes all the difference. For 900 processes in your body and knowing that magnesium builds out structure for many years in the body, dont be cheap especially when our products cost less than 3 dollars a week to use. You can call our source yourselves!
