I agree with the last post. It's expensive, but it works for the most part. I had some rather severe die off from using it. I was at two packets a day, then three. I went back to one. I was on the diet at the same time and taking other probiotics all the while. I gave my candida a wolop and a half and I paid the price. I would go slow. Die off can make things worse for you as you detox. Good luck on your quest.
