I use this for my restless legs. I used to suffer and was taking 4 advil a night just to get to sleep my legs jumped so badly. I developed an Ulcer from taking so much ibuprofen so I had to find something else. A friend recommended this. I as so glad she did! I had immediate relief. I take three a day. One in the morning and two at night. I recommend eating something, like crackers or small cup of yogurt, as it can cause stomach upset if you eat on empty stomach. I love this brand and have been using it now for over 3 years
