Can you take Low Dose Naltrexone (LDN) and Cytomel?
Are there any known problems with taking 4.5 mg of LDN and 60 mg of NP thyroid plus Cytomel together in the morning?
Basically, the answer to that is no. If you're taking it regularly, then there really is no issue with that at all. Some people have suggested that taking LDN at the same time as natural desiccated thyroid might cause some issues with absorption, but really, the way that they are absorbed so rapidly, there really should be no major effects there. Just don't take the natural thyroid with milk as milk can prevent its absorption.
