Just added 240 tablets of Potassium iodide to the stockpile. People over 40 don't really have a need it but it won't hurt. For kids, breastfeeding women etc it's vitally important in the event of nuclear fallout. Note it's potassium IODIDE not IODINE. Either will work but IODIDE is better. It can also be used to purify water at 65mg per gallon. By purify I mean decontaminate from living organisms like bacteria and parasites,, not remove harmful solids, chemicals, metals, etc.
