Has anyone here ever heard of this doctor ( Dr. John C. Lowe) and know anything about this product, Thyrogold?? I stumbled upon a link to this man's website, and began reading. It is interesting, and the Thyrogold sounds good, but when I wrote asking the question about this product actually containing active T4,T3, and the others, I have yet to get a response. I have sent two letters asking the question. No response is suspect to me. I read somewhere that any OTC supplement cannot contain any active enzymes or hormones... if it is a thyroid product, these must be extracted first before selling them. Does anyone know if this is true? Persently, I am taking Armour, and was wondering if I could add Thyrogold too, but since I get no response from Dr. Lowe, I thought someone here might have some answers. thank you!!
