Magnesium chloride is a fairly common food additive that has a long list of beneficial properties. First of all, this substance helps preserve youth, having a positive effect not only on a person’s appearance, but also on the condition of his body as a whole - it normalizes the functioning of many systems, improves the condition of the skin, hair and nails, and helps in the fight against infectious diseases. Moreover, magnesium chloride has a positive effect on representatives of all age groups - its presence in the diet is important for both children, adults and the elderly.
In addition, magnesium chloride has a positive effect on a person’s emotional state, it helps in the fight against depression and dizziness, and also fills a person with energy, which is especially important in winter, when almost everyone experiences chronic fatigue. However, taking magnesium chloride is not recommended in combination with taking antibiotics, since the substance tends to reduce their effectiveness.
As a food additive, magnesium chloride acts as a stabilizer, preservative and emulsifier. In food products it is designated under the index E511.
What is magnesium chloride: its features
Magnesium chloride is an inorganic compound. Externally, it appears as hygroscopic crystals that are white or completely colorless and transparent. Magnesium chloride has no odor at all. The compound is highly soluble in water and alcohol. The decomposition process begins when the temperature rises to 300 degrees. The substance begins to melt when it reaches 713 degrees.
Magnesium chloride easily reacts with salts that contain cations that can form an insoluble salt with chlorine anion.
Magnesium chloride contains two components: chlorine and magnesium. The substance is widely used in a variety of industries; it can benefit the human body and normalize many internal processes.
If there is a deficiency of magnesium chloride in the body, a long list of various diseases can develop.
Mole
All substances are made up of atoms and molecules. In chemistry, it is important to accurately measure the mass of substances that react and are produced as a result. By definition, the mole is the SI unit of quantity of a substance. One mole contains exactly 6.02214076×10²³ elementary particles. This value is numerically equal to Avogadro's constant NA when expressed in units of mol⁻¹ and is called Avogadro's number. Amount of substance (symbol n
) of a system is a measure of the number of structural elements. A structural element can be an atom, molecule, ion, electron, or any particle or group of particles.
Avogadro's constant NA = 6.02214076×10²³ mol⁻¹. Avogadro's number is 6.02214076×10²³.
In other words, a mole is an amount of substance equal in mass to the sum of the atomic masses of atoms and molecules of the substance, multiplied by Avogadro’s number. The unit of quantity of a substance, the mole, is one of the seven basic SI units and is symbolized by the mole. Since the name of the unit and its symbol are the same, it should be noted that the symbol is not declined, unlike the name of the unit, which can be declined according to the usual rules of the Russian language. One mole of pure carbon-12 is equal to exactly 12 g.

Origin [edit]
Chemical composition of sea salt
The magnesium content of natural seawater ranges from 1250 to 1350 mg/L, which is about 3.7% of the total mineral content of seawater. Dead Sea minerals contain significantly higher levels of magnesium chloride at 50.8%. Carbonates and calcium are essential for the growth of corals, coralline algae, mollusks and invertebrates. Magnesium depletion can be caused by mangroves and excessive use of lime water, as well as by excess of natural calcium, alkalinity and pH values. [18] The most common mineral form of magnesium chloride is its hexahydrate, bischofite. [19][20] Anhydrous compound is very rare, such as magnesite chloride. [20] Magnesium chloride hydroxides, korshunovskite and nepskoite are also very rare. [21] [22] [20]
Acceptable standards for the use of magnesium chloride
Magnesium chloride is one of the most important compounds for the human body: approximately 60% of the substance is found in bones and teeth, another 20% of the compound is found in muscle tissue, and another 20% in tissue and the brain. Accordingly, it is extremely important to maintain a sufficient amount of magnesium chloride in the body: its deficiency can lead to problems with teeth, increased bone fragility, and deterioration of brain function.
Magnesium chloride deficiency most often occurs in adults and the elderly.
The daily intake of magnesium chloride varies depending on the gender and health status of the person. Thus, experts recommend that adult men consume 350 to 400 mg of the compound daily, adult women – 300-350 mg, and pregnant women and girls – 500 mg.
Before you start using magnesium chloride, you should consult a specialist - he will prescribe a specific drug and the required dosage, based on your age, gender, health status and life characteristics.

If you have kidney disease, you should not abuse magnesium chloride - it can lead to the development of kidney failure.
Instructions for use of magnesium chloride
Magnesium chloride as a medicine
Magnesium chloride as a drug is prescribed both intravenously and intramuscularly. Infusion solutions cannot be stored for long periods of time and must be used immediately after preparation - otherwise there is a high risk of harm rather than benefit. For infusion administration, it is recommended to dilute the drug with a solution of sodium chloride and glucose.
When administered intravenously, the daily dose of the drug is 72 ml.
Magnesium Chloride as a Food Additive
Most of the magnesium chloride is used in the pharmaceutical industry, but the food industry does not want to give it up. The Japanese are especially keen on the additive, consuming huge amounts of soy cheese and soy milk, which contain the additive.
As an independent food additive, magnesium chloride is sold in the form of tablets. You can use it directly, or you can use it in the form of a solution. This will require 1 liter of water, 30 grams of magnesium chloride and 1 spoon of fortified wine.
The daily dose of the drug should be determined by a specialist based on the patient’s health status and age.
The maximum permissible daily intake of magnesium chloride is 350 g.

Hazard class of magnesium chloride and features of its storage
Magnesium chloride belongs to hazard class 3. That is, to moderately hazardous substances. The lethal dose of such compounds is 2500 mg/kg
Magnesium chloride is non-toxic, completely sterile, fire and explosion-proof, absolutely hygienic, does not generate dust.
The food additive is packaged in dense plastic bags of 25 kg each or in special plastic containers weighing from 0.5 to 1 ton. Packaging in other containers and materials is also possible - all depending on the consumer’s requirements.
Transportation of magnesium chloride by all existing modes of transport is allowed. The shelf life reaches 12 months.
How to take Magnesium Sulfate for weight loss
Before dieting, it is necessary to cleanse the intestines. Magnesium sulfate in this case is intended for one-time use. This method should not be used frequently, since the active substance irritates the gastric mucosa and can ultimately cause dysbacteriosis.
Those who want to lose weight need to add 200 g of powder to the bath. This bath should be taken for 20 minutes before bedtime. The course contains no more than 15 such procedures. It should be done no more than twice a week. The effect is achieved as follows: unnecessary fluid leaves the body, swelling disappears, and metabolic processes improve.
