Vitamins and Synthroid Do They Mix or Not?
Posted over a year ago
I just got my prescription renewed for synthroid. I saw a medical alert that you should take no vitamins until the medication has been in your system for four hours. Have you heard about this?
Karly122 - Hi. Yes, this applies to iron supplements or vitamins containing iodine. I don't know which others. I take a women's vitamin about 2 hours after my synthroid, but it contains no iron or iodine. There is something about calcium supplements, I believe. Maybe to be on the safe side, you can take your vitamin with lunch.
Hageter4 - I read the same thing that calcium and iron supplements can alter its effectiveness. I take my multivitamin at lunch around noon that is about 6 hours after I take my synthroid. I was actually going to ask my PCP about this because my vitamin does have iron in it.
