Thanks, Finnmaid - I'm inclined to agree with you. And, you are so very right about consistency - consistency is key with all aspects of thyroid disease.
And, rather than me continue to possibly be giving the wrong advice, I did a little searching about dosing Cytomel/liothyronine. Here's what WedMd had to say:
Obviously, no mention was made of calcium yet mention is made of "vitamins/minerals"....another site only mentions calcium (not iron)
And, both sites say 4 hours
I guess I didn't research more extensively when I first started Cytomel since I don't take calcium and/or iron supplements.
And, I must admit, I put faith in the recommendations a long-time T3 user gave me - she said I didn't have to worry about interactions.
I now realize I am fortunate since the vitamins, minerals and supplements I take (Centrum Silver, flaxseed oil, selenium, B12, Vit D3) are not interfering with my Cytomel.
I sit corrected and apologize for my mis-information
My recommendations on here will be different from now on....always learning....always learning
