underactive thyroid
"There is a level of inconsistency in its quality and in its potency. I have tried taking it in different ways. Starting with swallowing it (cause immediate bloating). Tried it sublingually and finally crushing it. Again, I have found some difference in the way it crushes. Some are crumbly (more potent) and some are sticky (same batch).  One whole box was totally useless. I didnt realise this immediately. Side effects kept increasing with each dose and I kept feeling tired, nauseated, and lacked energy. This effect wore out 4-5 hrs after taking the pill and felt almost back to normal. I opened a new batch and things improved withi 2 days..less side effects and more energy levels. Other side effect is sweet taste. I will try a different brand"
