I am 55 yr. Female, always had stomach issues. Getting older, I am experiencing indigestion worse than ever...even when I don't eat! I wake up with an empty stomach, yet still feel awful. Doctors are no help. So I bought my first jar about 2 and a half years ago. I was hopeful. My first few weeks, it made my stomach aches subside, but introducing any new product to your body works at first. So, to save money, I bought 3 jars and used them. There is only 30 servings per jar, so I have consumed a lot of jars over 20 jars I used more than once per day sometimes. My last interaction with customer service, I ended up buying 6 jars (for a lot of money). Buy 3 get 3 free or something like that. Now, here I am after consuming this stuff for over 24 months I still have 4 jars I don't want and won't use. I don't like that the powder is so finely ground, it ascended into the air as I was using it. It gagged me and made me cough. Then, even after shaking vigorously for 2 minutes, it was still chunky and didn't blend well, so I had to use my blender. Not quick and easy. It is beyond tart when drinking it, almost burning my throat, so I would just slam it down. I am not using it any longer and trying to get rid of 4 jars. Customer service won't take them back. I have had several emails and chats with customer service over the last 2 years for different topics and none of them were good experiences.
