As I age, "that time of the month" has presented a few surprises that I learned to control with diet changes, but once in a while I slip and all of a sudden I'm bloated, fatigued, and swollen. I've tried a few other brands, but they aren't as effective for me. Diurex is a gentle diuretic used to relieve menstrual bloat & puffiness, water weight gain, related fatigue, bloating and a "full" feeling. Gluten Free and recognized to be safe and effective by an FDA Expert Advisory Panel as used when directed, which may or may not mean anything to you, depending on how you feel about the FDA. lol I've used these when needed for the past few years and haven't experienced any side effects, personally. I would recommend it to a friend!
