Does the selenium and molybdenum go well with my thyroid meds?

Yes, you can take the selenium and molybdenum around the same time as your thyroid medications in the morning if you want. The selenium in particular will help your body convert T4 into T3. So taking it soon after you take your thyroid medication is actually a good idea. You may find that you will be able to lower the dosage of your T3 medication. Pay close attention to how you feel and see if you start to experience symptoms of HYPERthyroidism. That's a sign that you can lower your dosage.
