I am also on thyroid supplements. Never heard of dairy interferring with it. Was the website where you saw this reputable or another one of the all-too-many fear mongering sites? I would suggest you ask your pharmacist where you get your prescript. filled, or do a web search on the actual name of your thyroid med. to see if dairy is listed as something to avoid.
i know when i get my scripts filled they all say take on an empty stomach and all the websites i have been on say the same, take seperate from dairy, vitamins, etc….my way around this is i take my sublingual and i don’t have a problem
The only thing I can think of is that milk contains calcium and you should not take thyroid meds within 4 hours of taking calcium.
