I would say that enjoying a NutrBlast smoothie at least once, and many times twice a day, has definitely helped not only with PMS, but it has also helped throughout my monthly cycle. Prior to making smoothies, I had bloating, lots of pelvic pain and long, heavy periods. I am noticing less to almost no bloating or pelvic pain and my long heavy periods have lessened. I am also less moody. The NutriBullet has also helped increase my energy levels. Thank you for this awesome product and the Natural Healing Foods recipe book is a bonus, must have!
