Re: Levothyroxine + selenium-take together?
In my opinion, you could drive your self crazy, sorting through all the opinions on what will bind with what, and how.
To play it safe, I always take my thyroid meds by themselves, at least 4 hours after any thing other than water, and I wait one hour after meds for anything other than water.
I would especially not take supplements with my thyroid meds.
Beyond that.... you could get into the science of it. I don't know about Selenium, but I'm pretty sure Calcium will bind with the meds, and cause about a 50% drop in absorption.
Selenium has a long half-life, so there wouldn't be any benefit to taking it at any particular time of the day.
My opinions only, not medical advice. Always follow advice of your Doctor, not what I say here.
