Yes, they are diet pills. No, they do not contain ephedra. I know all to well the trouble I could get into if they did. However, they work well and I am getting serious about losing weight. I have been pretty good about staying under my calorie allotment everyday but some days I am usually starving by the end of the day. I am tired of feeling hungry so I am doing something about it. One a day in the morning keeps me from just sitting around and eating when I am bored.
