I understand that the new formulation added sucrose which is not good! I actually discovered this by accident while taking it I happened to bite it and noticed the sweet taste. Now, I've been on this medication for over ten years and never tasted the sweetness. It has always tasted bitter before! Like I said for me finding out it had sucrose was by clearly accidental. I'd been feeling all mailased and stiff for over three months which had gotten progressively worse. I contacted the pharmacist and she told me about this change. I believe that is most likely why I've been feeling so badly! I'm going to have levels checked next week to determine if it's changed. I don't trust the accuracy of the practice used to determine what is considered normal. Since, for over two years it showed my levels normal, when they weren't. We've got to watch out what's being added to our medicines as well as our foods. Notice we're all getting sicker and heavier than ever before.
