I have always had restless legs and especially at night. My husband says it is like I am riding a bike all night long. When I was introduced to CHF#2 Cal-Mag quite a few years ago I found that it quieted my legs and I do not even have any problems when I am faithfully taking the supplement. Sometimes I have run out and since I am 1000 miles away, I will go to the local health store and get a cal-mag supplement, but it never does the job of CHF#2 Cal-Mag. I have tried many other brands, but they do ot help me like the Country Health products do. Thanks to Dr. Klassen and his staff.
