Our magnesium spray is very simple, just magnesium "oil" made by mixing magnesium flakes with distilled water, then adding a splash of Young Living lavender essential oil for comfort. Applying magnesium topically absorbs straight into the blood stream better than taking oral supplements. Magnesium is good for the heart, it helps relax smooth muscle tissue, ease muscle aches, pain, and spasms, and also good for the cognitive and nervous systems. Studies have also revealed magnesium can help with blood sugar, blood pressure and so much more.
