I'm so sorry two customers got a bad batch or bottles. Mine is 2014 expiration and very fresh. I don't normally take the time to review products and I use I Herb all the time. This product doesn't deserve such a low rating. These are two key supplements in one and recommended in Dr Mark Hyman's book "Blood Sugar Solutions" for detoxification. I'm reordering.
