Maggot and Tackdriver303,
The concerns you both have about Potable Aqua iodine tablets are not an issue for me or any other experienced climber or hiker, even if you ingest 2 or 3 ounces of pure iodine crystals the most that could happen to you is that you could possible get sick and possible die.
But if you but if you eat something afterwards you might not,
but if you are allergic to iodine you probably will.
Discuss it with your Doctor if you doubt the validity of the information.
The Potable Aqua iodine tablets are save even in the amounts you outlined.
What Doug is telling you is the best information available on the subject!!!!!!! I have been hiking and climbing for 20 years, this site has first class information.
