Buying Guide
- Strength and dosing: All listed options are 130 mg per tablet, the standard adult dose. Dosing guidance recommends 130 mg for adults and 65 mg for children, to be used for up to two weeks in a short-term scenario.
- Shelf life and stability: Many products cite long shelf-life potential due to iodine salt stability. Plan for rotation and verify expiration dates periodically to ensure potency during emergencies.
- Quantity and storage: Consider your household size, space, and how quickly you need to access doses. Larger bottles suit offices or large families; smaller packs fit travel kits.
- Made in USA and third-party testing: For risk-averse buyers, products manufactured in GMP facilities with independent testing may offer additional assurance of purity and consistency.
- Divisible tablets vs. capsules: Tablets are easier to divide for precise pediatric dosing, whereas capsules can be harder to portion in field conditions.
- Emergency use guidance: KI is intended as a protective measure in radiological events. It does not replace evacuation or other safety protocols. Consult local authorities for recommended dosing during real events.
- Storage considerations: Keep in a cool, dry place away from children. Label kits with dosing guidance, emergency contacts, and expiration timelines.

- How long should KI be used after exposure? KI is used for short-term protection, generally up to two weeks, as part of a broader emergency plan.
- Do all brands provide the same potency? All listed products specify 130 mg per tablet, but verify lot numbers and expiry dates before use.
