Magnesium spray, often called magnesium oil, is a simple homemade solution designed to deliver the mineral through the skin via transdermal delivery. This method offers an alternative to oral supplements, which can sometimes cause digestive upset. The resulting liquid feels slick or oily on the skin, earning its common name, even though it contains no actual oil. Preparing the spray at home offers significant cost savings compared to store-bought products and allows for complete control over the ingredients.
Essential Materials and Preparation
The foundation of an effective homemade spray requires magnesium chloride flakes. These flakes are superior to common Epsom salts (magnesium sulfate) because the chloride form is more bioavailable for skin absorption. Magnesium chloride is wholly soluble and readily breaks down into ions the skin can easily utilize. Using high-quality, food-grade flakes ensures a pure mineral source for topical application.
The liquid component must be distilled water, not ordinary tap water, to prevent impurities or trace minerals that could interfere with the solution. Tap water often contains contaminants that can reduce the spray’s shelf life or react with the magnesium. Preparation requires a non-reactive glass measuring cup or small pot for mixing and heating. Finally, a glass spray bottle is the best container for long-term storage, as glass will not react with the highly concentrated mineral solution.
Step-by-Step Mixing Instructions
The most effective concentration for the spray is a 1:1 ratio, using equal parts of magnesium chloride flakes and distilled water by volume. For a standard batch, measure one-half cup of flakes and one-half cup of water. This ratio creates a saturated solution that maximizes mineral delivery while remaining well-tolerated by the skin.
Begin by gently warming the distilled water in the glass pot or measuring cup until it is warm to the touch, but do not allow it to boil. Heating the water helps the flakes dissolve much faster and more completely. Once the water is warm, remove it from the heat source and pour the measured magnesium flakes into the water.
Stir the mixture continuously with a non-metal utensil until all the flakes have completely dissolved and the liquid appears clear. The dissolved mineral solution should be allowed to cool down entirely before it is transferred into the storage bottle. Once cool, carefully pour the liquid through a small funnel into the clean glass spray bottle and secure the cap.
Proper Application and Storage
The finished magnesium solution should be applied directly to the skin, with the best absorption occurring in areas where the skin is relatively thin. Common application sites include the abdomen, the tops of the feet, and the arms and legs. Applying the spray after showering is often recommended because clean skin may enhance the mineral’s absorption rate.
A common initial reaction is a slight tingling or itching sensation on the skin, which is generally harmless and often subsides with consistent use. This sensation is thought to be an indication of low magnesium levels and can be managed by applying the spray to less sensitive areas, such as the soles of the feet. If the tingling is persistent or bothersome, the solution can be easily diluted by adding extra distilled water to the spray bottle.
For maintaining efficacy, the magnesium spray should be stored in a cool, dark location away from direct sunlight and heat. A cabinet or drawer in the bathroom is typically sufficient for storage. When stored correctly, the homemade spray has an expected shelf life of approximately six months. Consistent daily application is often suggested to help maintain steady magnesium levels.
