Long shelf life, regardless of the expiration date.
For those that are concerned about expiration dates, this quote is from the U.S. NRC website:<br /><br />"Is it safe to take KI tablets with an expired shelf-life?<br /><br />Yes, potassium iodide tablets are inherently stable and do not lose their effectiveness over time. Manufacturers must label their products with a shelf-life to ensure that consumers purchase safe and useful products."<br /><br />Regulations require an expiration date. So, as long as you store it properly, you're good to go! 5 stars.
Rating: 5 stars
