EXPIRATION: 05/2032 - The NRC has stated that the shelf life of Potassium Iodide Tablets can be extended greater than 10 years due to the inherent stability of iodine salt mineral supplements. SUGGESTED USE: For short-term use only (up to 2 weeks). Adult/Adultescent: 130 mg (2 tablets). Children: 65 mg (1 tablet).
300 REAL TABLETS: These are actually tablets that are easily divisible if needed for smaller children and infants. Capsules can't be divided easily and have a shorter shelf life than tablets. Use is the same as potassium iodate tablets, ki pills 130mg or other iodine supplements.
IODINE - Potassium Iodide (KI) is a stable iodine salt. Taking a stable iodine helps the thyroid absorb and be "full" of iodine. The body does not produce Iodine naturally, which makes 130 mg Potassium Iodide Pills perfect for emergency or survival kits.
GUARANTEED PURE - Our Potassium Iodine Drops, potassium iodide tablets, and potassium iodine pills use USP grade Potassium iodide crystals directly from the source. We offer 3rd party lab tests that test for heavy metals, potency, purity, and much more.
MADE IN THE USA: We are the only brand that sources, tests, produces, and ships everything from our own in-house FDA registered Food-Grade facility. That's why we can offer the best quality and the best price. Our bottles never say "Manufactured For" like everyone else. We produce many iodine supplements including Potassium Iodide Pills and Potassium iodide 130 mg tablets.
