A member asked:

Does taking multivitamins and biotin interfere with taking thyroxine?? thanks

A doctor has provided 1 answer

Ideally: thyroxine should be BRAND NAME and taken in the AM, 30 minutes before food. In addition, you should not take calcium, iron or vitamins within 2 hours before or after thyroid dose to avoid interference.
