Frequently Asked Questions

Can I take in too much Zechsal magnesium?

The answer is simply ‘no’. Any excess magnesium is just expelled by the kidneys. Persons with severe kidney conditions are advised to not use Zechsal products.

Why is absorption through the skin better than taking tablets?

When it’s absorbed through the skin, Zechsal is directly transported to where it’s most needed – to the cells. Skin absorption leaves the gastrointestinal tract unaffected. The chances of getting diarrhoea – a side effect of taking magnesium tablets – are minimised. No unnecessary breakdown of the active ingredient takes place and its intake (absorption) by the body is maximised.

Where can I find directions for use?

When you order Zechsal from this web shop, you’ll receive directions for use along with your products. These will include recommended dosages, applications and hints for use. You could also use the following link!  Click here for directions for use.

What is the composition of Zechsal?

All our products are 100% natural and consist of pure magnesium chloride and water. Only the body gel contains an additional thickening agent, a natural starch. Our products are not tested on animals and don’t contain any preservatives.

But isn't there magnesium in the food that we eat?

Definitely. Wholewheat bread, bananas, soya, nuts, green vegetables, cocoa and many others foodstuffs contain magnesium. However, many people (unknowingly) suffer from a magnesium deficiency.

This is because of our eating habits, but also due to the fact that our food contains less magnesium than it used to. The latter is cause by the depletion of our soil. Whether or not you need extra magnesium depends on a number of factors. Also read through “Do you suffer from a magnesium deficiency?”.

When is what product recommended during and after sports?

In the case of intense exercise, the use of Zechsal just beforehand is not recommended. Your muscles can become too relaxed, thus hampering optimal performance. The use of sport spray is recommended in case of cramps during exercise, or afterwards to aid recovery. It’s fine to use it before participating in recreational sport.

Furthermore, a bath or foot spa the evening before intense exercise comes highly recommended. It’ll help you get a good night’s sleep and give you energy for the day to come. To recover afterwards, a bath with 1 or 2 kg of magnesium yields tremendous results! Your muscular pain will disappear and your joints will feel less stiff.

What's the difference between Zechsal and Dead Sea Salt?

Zechsal and Dead Sea Salt are similar in that they both, for the most part, consist of magnesium chloride. However, Zechsal is purer and more concentrated. The Dead Sea is located on the earth’s surface and is subject to pollution by humans and the environment. Zechsal, on the other hand, is untouched and comes straight from 1600m underground.

Why use Zechsal instead of Himalayan salt?

In its composition, Zechsal is not at all comparable to Himalayan salt. The only similarity is that they both originate from a prehistoric sea. Himalayan salt is 97-98% sodium chloride, so it’s basically regular table salt. It also contains 2% magnesium chloride, its most active ingredient. Zechsal has a much higher magnesium chloride concentration (47%), so it’s much more effective!

I feel a tingling sensation when I apply Zechsal to my skin.

This is not at all harmful, but it can be an unpleasant feeling. In order to slowly become used to the product, you can dilute the gel or oil with water and gradually increase its concentration.

Good for the skin, good for the muscles, combats stress... It's starting to look like some kind of magic potion to me.

Magnesium is a vital ingredient which assists in more than 350 biochemical processes that take place in the body. For this reason, magnesium (deficiency) is related to many, extremely diverse symptoms.

Can I take in too much Zechsal magnesium?

No. Zechsal contains naturally-occurring magnesium chloride. It is therefore not a medicine with potential side-effects. Instead, it is a natural mineral that we need on a daily basis. Any possible excess magnesium is simply expelled in a natural way by the kidneys (similar to vitamin C). Persons with severe kidney conditions and abnormally low heartrates are advised to consult their physicians before use.

Can I make magnesium oil by dissolving the crystals?

Zechstein Minerals and the Magnesium Health Institute have run tests and have reached the following conclusion: “We do not recommend the use of crystals as a base for highly concentrated magnesium oil (>5%).” The crystals are produced by means of an evaporation process. Here, the magnesium solution from the source is heated to 160 °C. The water is allowed to evaporate until a magnesium chloride concentration of 47% is achieved. This concentration is ideal for the production of magnesium chloride hexahydrate, which creates a stable solid following crystallisation on a cooling belt. As a result of the heating process, a small amount of the magnesium chloride decomposes to form MgOHCl (magnesium chloride hydroxide), MgCO3 (magnesium carbonate) and some HCl (hydrogen chloride) during evaporation. These products are responsible for the white haziness that can be seen as the crystals dissolve. They are not directly hazardous, but are by-products created during this essential step of the crystal production process. They are perfectly suited to applications with concentrations of up to 5%, such as bath crystals. For topical applications (onto the skin) with higher concentrations, we recommend the purest and most natural magnesium oil, unheated and straight from the source. This magnesium oil is guaranteed suitable for use on the skin.
