I have been diagnosed with underactive thyroid for the last twelve months and have been prescribed 50mg Oroxine (levothyroxine) by my Doctor. I have not been able to lose any weight and wish to lose 20lbs. Can I take diet fat burners/diet supplements to assist in my weight loss. I am on a low carb diet and exercise everyday. Can you suggest something for me to take that will work with my Oroxine?
