For general use I recommend magnesium oil applied transdermally so it will bypass the GI tract thus avoiding the side effect of loose stools that will limit the amount you can take in. With regular use deficiencies will be relieved. You can use 1oz of magnesium oil on your full body per day without concern. Oil can be applied multiple times per day to areas of pain or inflammation. Massage it in for a relaxing treatment.
One spray of Ancient Minerals Magnesium Oil will provide @ 18-20 mg. of magnesium chloride.
