I've been using this product for a little over a month now and love it. It does exactly what it says and makes bitter or sour taste sweet. I've let about 15 different friends and family try it and all were amazed at how it changed the flavor of traditionally sour or bitter food/drinks. I always suggest starting with a lemon to realize how the berry transforms sour to sweet. I've lost 12 pounds since incorporating green juice smoothies into my diet with the help of this berry. If I want my spinach smoothie to taste sweeter, I just add more lemon juice. I haven't had any sugar, nor do I crave it with the help of this berry. For dessert, I'll have a berry and then eat a grapefruit or a carton of raspberries. This is a little pricey, but now that I know this really helps me have a healthier diet, I buy in larger quantities so that it's more cost effective.
