After having my thyroid radiated 5 yrs ago, not because of cancer, but hyperthyroidism, and started on thyroid medication( armour thyroid) I have experienced horrible bloating, constipation, thickness and weight gain. It does not seem to matter what I eat or drink the outcome is the same!!! I have tried all kinds of enzymes and probiotics to no avail. A friend gave me a few packets of a Renew product, which I never found out the name of, which absolutely made my constipation 100% better, no bloating and a flat stomach!! I called Renew to find out about what the product was, my friend did not know as she got them from her sister some time ago, and they knew exactly what I was talking about, but said the product had been discontinued!!! I was devastated!!!! These 2 fiber tablets and a probiotic in a little packet are the only thing I have found to help in 5 yrs!!! I can not take any of my supplements, eat or drink without all these problems!!!! I had my gallbladder out about 4 months after all of this started, so that does not help either!! Does anyone know anything about these products and if something like them might be available somewhere else???
