I don't like using artificial sweeteners because of the chemicals and because they don't taste good. I am a caregiver for my diabetic dad, and once I discovered this product I was hooked, except that it is hard to find where I live. When I found it at Amazon I put it on auto ship so I don't run out.  The price has gone up a lot since I first found it on Amazon, however, it still costs more in stores if and when I can find it there. I make limeade with this which I keep on hand at all times. In a gallon container of water I add 1 cup of lime juice and 2tbsp. of stevia powder. It is refreshing and almost no calories and no chemical aftertaste.  My dad uses the stevia in his coffee and his oatmeal. I haven't tried cooking with it although I know they make one designed for baking, which I'll possibly try this winter.

This bone is nothing more than a big dog treat.  I have a 2 yr old Pit who ate through the souper in 5 minutes.  After reading other reviews I took it away from him and will save the rest for a later date.  I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat.  Will not be buying this again.

These crackers used to taste delicious and, although not necessarily the healthiest snack, they were really great to munch on! But, I just recently opened a box and, after one telltale bite, I was disappointed to find that they now add autolyzed yeast extract, a common favor enhancer that is practically the same as MSG.  I have adverse reactions to both MSG and autolyzed yeast extract. Too bad they ruined this product for me and other MSG-sensitive folks out there.  I wonder why they did it?!
