I was quite skeptical about stevia at first, but tried it with another brand and thought there wasn't much difference in taste and I felt better about using a more natural product than the other artificial sweeteners out there. I then started looking at getting a bulk container and happened upon this product. I now have purchased this same product 4 times and am quite pleased. The product is a bit more concentrated and we are using less of the product in our drinks and cooking than other competitors.  The deliveries are always quick and we have not had any issues at all with the product or packaging.

Ex Output:
Positive

I have dogs who are 85 pounds. They chewed the bottle toy in less than 10 minutes; trashed it. I have not tried this with a little dog.

Cutting sugar out of our diet,we went to splenda. Then finding that it was also unhealthy and baking with it made foods flat and dry. We went to stevia no calorie powder, after much research proved that stevia has been used for hundreds of years with no bad health effects. The trick to using stevia is to use tiny amounts and then taste it and add a bit more at a time to suit your taste. I also found that using a stevia that has an 80% ratio is the best tasting and this is the best that I have found. Because of using VERY SMALL amounts this jar lasts for months. This is also the best price ANYWHERE! Swanson is a trusted vendor as is Amazon.

Ex Output:

Positive
