I have found that a daily foot soak in magnesium oil is very helpful for leg cramps. I found magnesium oil on Amazon, Magnesium Oil by Wisdom Health. I buy half a gallon at a time (the half gallon lasts for weeks) and add 4 ounces to an inch of warm water and soak for 30 minutes daily in a plastic container that fits my feet.. I can use the same solution for 3-4 days, then I toss it out and start with a fresh batch.. Karen
