The magnesium spray was designed to give you all the benefits of our Magnesium Flakes but in a compact convenient spay. Great for post work outs, travel, and anywhere on the go. Spray directly on areas of tension pain or cramping. Magnesium aids to reduce anxiety, stress, aids in digestion and helps with sleep. Avoid eyes, mouth and any cuts. It may feel slightly tingly at first but sensation will dissipate as it goes to work. If sensation continues wipe off with a warm cloth.
