After contacting the manufacturer of this "USED TO BE MOST WONDERFUL" product, I was very disappointed to hear that the formula has been changed. Below, is the response I rec'd. I will add that the company was very quick to respond to my inquiry, and were very up front about the situation, which I very much appreciated.
Our stevia extract changed in May 2013. We simply had no choice but to
change our extract. The extract that we had been using is no longer
available. The matter was out of our hands.
