Magnesium chloride (MgCl 2) is a magnesium salt that is abundantly present in the waters of the Dead Sea. MgCl 2 salts, selected from these waters, have been comprehensively studied regarding their impact on skin function and their use in compensating for magnesium deficiencies in the human body.
Magnesium Chloride
Magnesium (Mg) is an essential trace element that fulfills numerous vital functions within the human body. It is crucial to note that magnesium cannot be administered in isolation, as it only exists in combination with other elements or compounds. We can differentiate between organic forms with enhanced bioavailability, such as magnesium aspartate and magnesium citrate, and inorganic compounds with reduced absorption rates, including magnesium chloride, magnesium oxide, and magnesium carbonate.
Applications and benefits of magnesium chloride
Magnesium chloride is an exceptionally important mineral that performs a wide range of essential functions in the human body. It plays a crucial role in the synthesis of various enzymes involved in metabolic processes, facilitates the transport of vital nutrients, hormones, and neurotransmitters through cell membranes, and participates in the production of energy in the form of ATP, which is essential for cell growth and development. Additionally, magnesium influences the proper functioning of muscles by regulating contractions and relaxations, and is involved in bone mineralization. It is worth noting that this mineral also possesses antibacterial properties, strengthens the immune system, supports the function of the digestive and nervous systems, and improves skin condition. Magnesium chloride can be supplied to the body through the consumption of magnesium-rich foods such as whole-grain bread, cocoa, sunflower seeds, or dark chocolate, or in the form of dietary supplements when the diet does not provide sufficient magnesium.
Medical and nutritional applications of magnesium chloride
During pregnancy, breastfeeding, chronic stress, and in individuals adhering to carbohydrate-restrictive diets, magnesium deficiency may occur. Contributing factors include excessive intake of animal fats, high daily coffee and tea consumption, alcohol use, and frequent consumption of phosphorus-rich products (e.g., sugary drinks, processed meats). Excess phosphorus and calcium supplementation accelerates magnesium excretion. Symptoms include persistent fatigue, concentration difficulties, hyperactivity, hand tremors, anxiety, irregular heartbeat, muscle spasms, and convulsions.
Oral magnesium chloride powder
Administering magnesium chloride powder dissolved in water represents an effective approach to addressing magnesium deficiencies in the human body. However, it is crucial that supplementation with synthetic agents is only considered after unsuccessful dietary modifications or in cases of critically low magnesium levels requiring immediate replenishment. As demonstrated by Kimata and colleagues, consistent intake of magnesium chloride yields noticeable benefits for patients with atopic dermatitis and eczema. The study involved participants who consumed 500 ml of purified seawater enriched with magnesium ions daily for 12 months, whereas the control group (consuming distilled water) exhibited no changes. Furthermore, individuals consuming water with high Mg2+ concentrations showed a reduction in immunoglobulin E (IgE) levels and pro-inflammatory cytokines in their blood, a trend not observed in the control group.
Magnesium chloride for therapeutic baths
Preventive baths supplemented with magnesium chloride facilitate the benefits of its properties while promoting relaxation after a demanding day. Such therapies are advised for individuals with various dermatological conditions, including atopic dermatitis (AD). In an intriguing study by Proksch and associates, researchers examined the effects of bathing in Dead Sea water, abundant in MgCl2, on AD patients' skin health. They determined that these baths substantially enhanced the skin's protective barrier function against detrimental external agents.
Magnesium chloride for joint support
A natural compound sourced from the Dead Sea, available in pharmacies and supermarkets, is utilized to improve the well-being of individuals with joint issues. The mechanism involves reducing inflammation by enhancing magnesium intake. This leads to a decrease in blood calcium levels, the excess of which can deposit in joints, triggering arthritic pain. Magnesium is an essential element for proper bodily function. It is advisable to maintain adequate magnesium levels through diet and periodic magnesium baths, as this mineral is effectively absorbed through the skin.
