Bests & Worsts Reviews from Amazon

I’ve purchased this product quite a few times now. First couple times was fabulous. No taste. Blended right into my coffee. I got the 2 lb container and had stomach pains immediately mid coffee. I contacted the company and they replaced the container with two one lb container which were fine. I repurchased when they recently went on sale and I figured I would stock up thinking the bad container was a fluke. Anyway, so far 2 of my containers seem to give me horrible stomach pains again. I’m afraid to open the third. I’ve contacted the company again and I have had zero responses in days. The first time the response was immediate. Something is obviously inconsistent with this product. And i seem to not be alone as I read the reviews. Hopefully the company contacts me with some sort of update. I wonder why these were so cheap on sale now ?! I should add that when I saw the sale I contact the company via Instagram to ask if they were discontinuing or reformulating before I purchased. They said no. So I’m anxious to hear back what’s going on.
