Our ionic magnesium chloride is harvested from the pristine waters of Utah's ancient inland sea, the Great Salt Lake.  Along with magnesium, it includes 72 trace minerals including: zinc, copper, calcium, chloride, and selenium. Helpful for achy legs, anxiety, relaxation, sleeplessness, strengthens immune system, helps proper muscle function, improves bone strength and protects from loss of bone (osteoporosis), protection and recovery from arthritis, and helps with recovery from many other degenerative  diseases.  It is not an oil and you cannot overdose with it.  Your skin only absorbs as much as it needs.  **When you first start using it, your skin might feel a little itchy or even a slight sting for up to 30 minutes (and rarely some a rash).  This means that you're very deficient and once you've been using it for a few weeks daily, this will go away.  Best applied to arms, legs and stomach.  Start with a small amount on arms to see how you react and build up from there.
