Thyroid desiccated
"I have just started to take 1/2 tablet 2x day .  For 3 years I have tried every alternative out there - iodine, tyrosine, sea vegetables homeopathic etc, and got no where. My diet is very clean and kept inching up in weight even though I work out 6x a week. In 3 days I have seen a vast improvement in energy levels, and happier outlook, less frustration and overwhelming feelings.  Hopefully a little weight loss will follow."
