WE just take powdered magnesium by the 1/4 spoonful a couple times a day. Do google "magnesium deficiency". There is a two page quiz to determine if you are deficient. I had terrible pain in right hip and knee in August - totally cured now; improved greatly in first week of mag therapy. Nasty mood swings disappeared. Also completely eliminated nighttime leg cramps - as long as I remember to take it. An extra 200- 400 mg/day. I feel SO much better! I cannot eat bananas. One symptom of mag def is high BP. Too much = low BP. Also diarrhea.   

I take no prescription drugs.
