  1. Beccy Heenan

    No Weight Loss
    The only thing I can say is, it does help with sleep. I just finished my first bottle and no weight loss. I eat yogurt with berries, salads and a sensible dinner. I work at a hotel so am walking all the time.
  2. Kelsey Brown

    Works OK
    Haven’t noticed a change in weight yet, but it does appear to suppress my appetite a bit. I can’t say it’s my favorite product. There are so many things it just doesn’t help but I’ll keep taking it until the bottle is finished
