Does anyone take the Nutri Thyroid (Thyroid Glandular Concentrate)? Or the Nutri Thyroid Complex? I'm guessing the complex is for vitamin supplement but what does the Nutri Glandular Concentrate do? (I know what it is but just don'e understand why you would take it - will it affect the Levothyroxine by adding to it?) Sorry if it is a daft question!
