I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.

Ex Output:
Positive


Ex Input:
This just did not smell or taste like real olive oil.  And the smoke point was lower than it should have been.  Perhaps it was a bad batch, diluted with some other oil, but I'll never use it again.

Ex Output:
Negative


Ex Input:
the pop chips are really incredible. They are very flavorful and crispy. My Favorite is the BBQ, but that is just me, they are all good. I would highly recommend these to anyone who is watching their weight of just for overall better health.

Ex Output:

Positive
