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.
Positive

I was disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.
Negative

It didn't remove the spots... Now what am I going to do with all of the sponges I bought?

Negative
