100% pure magnesium oil. Highest potency available. Magnesium is very important for our body to function properly. Magnesium is best through our skin, so this transdermal spray is the perfect application. Most people nowadays do not get enough magnesium in their diets due to poor soil quality over the past decades. All you have to do is spray magnesium oil on your skin, especially after showering or bathing and massage in, and let dry. It is best to apply to clean damp skin to maximize the absorption of the mineral. It is normal to experience a mild stinging sensation for the first few weeks until your body has absorbed enough magnesium to not be deficient. The water has been Ultra distilled and tuned to the solfeggio frequency of 528 Hz for additional benefits. We recommend 14 to 16 sprays twice daily.
