I have read so many glowing reviews on Thai NDT. Some prefer Thyroid-S, others Thiroyd or TRMan, but it's difficult to find any negative reviews on any of them.
But some claim that since these brands are available OTC, they are not regulated, and there is no way of knowing exactly what they contain. I get the impression these statements are made by people who are not taking these drugs themselves.
But aren't the FT4 and FT3 levels standardized in these pills; at least that is how I understand it?
