My Daughter had to have half of her thyroid removed when she was 15 due to a tumor growing on the outside of it. The doctors did not want to put her on thyroid meds since her body would become dependant on them.. They decided that at her age and having half of the thyroid it would start producing enough on its own without the meds. The thyroid does produce but just quite enough. The doctors still do not want to put her on meds so she has been taking a thyroid supplement for a few years now. Her thyroid levels do tend to bounce around when she has bloodwork down but the levels are never low enough or to high to warrant the meds. The Doctors did suggest taking a supplement. This is the first time she has tried this particular brand. She has been taking them a few weeks now and has had no problems at all with them. There is no flavor or aftertaste to these pills. She has not experienced any side effects either. The pills are easy to swallow also. There 120 capsules in this bottle which will last 2 months since you take 1 in the morning and 1 at night. We will be buying more of these.
