Synthroid and Supplements

I  compete in figure bodybuilding and reqularly take creatine, glutamine, whey protein powder, and BCAAs.  What effect will synthroid meds have on these supplements and should I continue using them?

You should first ask your doctor and/or you can do a search for drug interactions.  You should also check to see if any of these supplements have soy in them as soy inhibits the absorption of thyroid med, so you may need an increase in med.........

Always take your supplements hours away from your thyroid meds.
Iron, Calcium should be taken 4 hrs away from meds.
