Magnesium chloride is a chemical compound composed of magnesium and chlorine, commonly found in nature as a naturally occurring salt. It appears as a white, crystalline solid and is highly soluble in water, making it useful in various applications where magnesium delivery is required. This compound is often used in dietary supplements, pharmaceuticals, and industrial processes due to its ability to provide magnesium, an essential mineral for bodily functions and chemical reactions.
In healthcare, magnesium chloride serves as a source of magnesium to address deficiencies, which can lead to symptoms like muscle cramps, fatigue, or irregular heartbeats. It may be administered orally, intravenously, or topically, depending on the intended use. For example, topical formulations, such as creams or bath salts, are sometimes employed to soothe muscle aches or skin conditions. Its bioavailability—the ease with which the body can absorb magnesium from it—is a key factor in its effectiveness as a supplement.
Outside of medicine, magnesium chloride is utilized in agriculture to enrich soil with magnesium, in food processing as a coagulant (e.g., in tofu production), and in industrial settings for dust control, road stabilization, or as a desiccant. Its hygroscopic nature (ability to attract moisture) makes it valuable in de-icing roads and maintaining humidity levels in certain environments.
When handling magnesium chloride, care is advised to avoid excessive exposure, as high doses may cause gastrointestinal discomfort or interact with other medications. Proper storage in dry conditions is necessary to prevent clumping or degradation due to moisture absorption. Always follow recommended guidelines for use, whether in medical, agricultural, or industrial contexts.

Effectiveness and Risk Overview
Condition | Effectiveness | Details |
|---|---|---|
| Hypertension | Magnesium chloride can help lower blood pressure by improving vascular function and reducing peripheral resistance. | |
| Causes respiratory problems. | Magnesium chloride can cause respiratory problems, such as wheezing, coughing, and shortness of breath, in people with pre-existing respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), by triggering the release of histamine, a chemical that constricts airways and increases mucus production. |
