Clen Thyroid?

Does anyone know if clen can be used by people with thyroid problems or if it would worsen it? If it can not what are some fat burners that can. My fiance was recently diagnosed with thyroiditis and really would like to lose some weight, any suggestions? Yes she is very good about her diet and exersise but still can't seem to lose weight. Thanks for the help

Is she taking levoxyl? and what dose? most fat burners inhibit thyroid function to some degree.

Has she had her TSH levels check? thyroiditis is just inflamation of the thyroid, which is usually caused by bacteria...
