Potassium Iodide (KI) and Potassium Iodate (KIO3) Review Article: Radioprotective Agents
 


How Products were Selected:
Products were selected to represent the majority of those commonly sold and/or available nationally in the U.S. ConsumerLab.com purchased products on the open market through on-line retailers. Products were not accepted directly from manufacturers.

Testing Methods:
Products were tested for the ability to disintegrate and the amount of iodine. Analyses for iodine were first performed ICP-MS (Inductively Coupled Plasma-Mass Spectroscopy) in an independent laboratory. Products not having passing levels of iodine were then re-tested in a second independent laboratory using the similar methods and instrumentation. The identities of the products were not disclosed to the laboratories performing the testing.

Disintegration of non-chewable, non-capsule, non-enteric coated and non-time-release formulations was analyzed utilizing USP (United States Pharmacopeia) <2040> recommendations entitled "Disintegration and Dissolution of Nutritional Supplements."

Passing Score: *
To pass testing, a product had to:
  1. Have a minimum of 92.5% of its labeled amount of elemental iodine and a maximum of 107.5% of this amount. (USP 25 official monograph; potassium iodide tablets)
  2. Meet recommended USP parameters for disintegration.
A product passed if it passed each criterion in any one of the analyses.

* Passing scores allow for specific margins of technical error associated with each analysis.ConsumerLab.com reserves the right to disqualify a product at any time from passing its testing if it considers such product to present a safety risk or to provide misleading or inaccurate information in its labeling.
