As documented on www.ki4u.com Potassium Iodide (KI) is very hardy and has been proven to be viable well beyond it's "official" expiration dates as seen there....

Jerome A Halperin, Executive Vice President - CEO of The United States Pharmacopeial Convention, Inc. wrote to the Chairman of the U.S. Nuclear Regulatory Commission on January 30, 1998 of an assay he had done on "expired" Potassium Iodide (KI) tablets.

After the USP Drug research and Testing Laboratory analyzed samples, they showed that approximately 11 years after their manufacture and eight years after their expiry date, the tablets asseyed at 99.1% of the labeled content of potassium iodide. (This result was well within the rubric range of 92.5 to 107.5% required by the monograph.

Mr. J. Halperin should know what he is talking about. In 1979, while deputy director of the bureau of Drugs of the Food and Drug Administration, he directed the effort to get Potassium Iodide Solution, manufactured and stockpiled in Harrisburg, Pennsylvania during the Three Mile Island incident!

Bottom Line, KI is very hardy stuff, same as what's used i your iodized salt to make it "iodized", as you'll see there listed on your salt container label. And, like salt, if you keep it dry and don't try to melt it, it'll last, and still be good, for many more years.

We've been selling KI & KI03 since 1999 and have had many customers coming back, wanting to re-order over the years as their expiration dates came up, and we've willingly lost those additional sales, and saved them money, by simply sharing the above with them.

If, however, for any reason you are not comfortable with any late expiration dated KI, simply return any unopened bottles and we will promply refund your money in full.
