T4 Vs T3 Interference with Other Substances

Hi everyone .. I just would like to know if T3 medications interfere with other substances from food, supplements or other medications like T4 does?

I'm having hard time avoiding a wide range of food/drinks and supplements to feel good with T4 only medication.

Thanks

Ali

Food can interfere with the uptake of both T3 and T4 but as long as you leave 2 hours after eating - it should be fine.

As regards T3 as I take one daily dose first thing and wait approx 1 hour before breakfast, I avoid anything interrupting as I have a normal life. All supplements I take at lunchtime as most are to be taken with food. I would also leave a good gap between other medications I might have to take.

I've also taken T4/T3 together when on a combination in one dose.

Not what you're looking for?
