For those on synthroid - food interactions?

The four hour window after taking your thyroid medication is for foods high in calcium or calcium supplements, as well as foods very high in fiber. Calcium and fiber both block the absorption of the thyroid meds. Otherwise, just wait your thirty minutes to an hour. I found out the hard way that the calcium and fiber render the meds ineffective and don't recommend messing with it.

Supposedly iron interacts with Synthroid also, so wait a few hours before taking a multivitamin or iron vitamin. Or red meat, I guess.

I take my Synthroid before bed because the whole "waiting to eat" in the morning was a pain. No issues for me.

I do recall though that anything with calcium, including multi vitamins, should not be taken within 4 hours. And also veggies such as kale, cabbage and Brussels sprouts are not good for absorption.
