Iron plus vitamin C supplements

[foxglove]

Do iron + vit.c supplements need to be stopped before a thyroid blood test?

No, you only need to stop iron supplements before an iron test (7 day gap).

When doing thyroid tests take any supplements after the test on the day. Of course, Biotin or B Complex should be left off for 7 days.
