Any Preparation Needed before 24-hour Iodine Test??

[Guest guest]

I finally ordered the 24-hour Iodine Loading Test as well as the

Bromide test from Hakala.

I know I'm not to have any supplemental iodine in my system, and the

last time I used any was a week ago (and it was only on the skin for a

scrape). I wanted to wait until I have these test results before

starting supplementation.

Do I need to use vitamin C, sea salt, or other supplements either

before or on the day of the 24 hour collection?

Thanks very much for any advise.
