I’m on my second 10-pack (14 pills each/140 total) of IOSAT Potassium Iodide Tablets. With a 10-year shelf life, and the 2nd pack expiring next year...it blows my mind I’ve had these around for almost 20 years. I’ll be ordering another round soon...and upping the quantity thanks to your suggestion for the grandchildren. I hope the 3rd round expires also! Thank you!
I’d suggest that they really don’t expire. I certainly ignore the expiration dates on mine.
And to expand on that - it’s a salt, the chemical bonds are very, very strong. Nothing that happens in your closet or basement is going to break that, as long as you keep it dry, unless you’re suddenly sitting on an active volcano. In which case, it’s been nice knowin’ ya!
Looking across the way to the clear salt grinder with the pink Himalayan salt in it - that pink salt sat there for probably millions of years before someone dug it up and sold it.
Remember the ages Potassium Iodide Tablets are useful for and the cut-off age for their use.
I don’t know if the sites that sell the stuff mention the ages.
“KI is recommended only for people under 40 and pregnant or breastfeeding people.”
KI protects only against radioactive iodine and does not protect against other types of radiation.
KI protects only the thyroid. KI does not protect other parts of the body.
KI must be taken within 24 hours before or 4 hours after exposure to be most effective.
KI is not a treatment and cannot reverse damage already done to the thyroid.
KI may not give a person 100% protection from radioactive iodine.
Most radiation emergencies will involve other types of radiation and not radioactive iodine alone. Radioactive iodine is most common in nuclear power plant incidents.
