Potassium Iodide (KI) — Manufacturer & Supplier
USP | BP | IP Grades Available | WHO-GMP Certified | Bulk Institutional Supply
Potassium Iodide (KI) is a critical nuclear countermeasure used to protect the thyroid gland from radioactive iodine exposure. Golden Hour Pharma supplies pharmaceutical-grade KI tablets and oral solutions to governments, defence organisations, hospitals, and national stockpile programmes across Africa, MENA, and Latin America.
What Is Potassium Iodide (KI)?
Potassium Iodide (KI) is a stable, non-radioactive salt of iodine with the chemical formula KI. It is classified as an essential medicine by the World Health Organization (WHO) and is included on the WHO Model List of Essential Medicines for its role in thyroid protection during nuclear and radiological emergencies. The U.S. Food and Drug Administration (FDA) has approved KI as a thyroid blocking agent for use in radiation emergencies involving the release of radioactive iodine.
In pharmaceutical form, KI is available as scored tablets (65 mg and 130 mg strengths) and as an oral solution. It is manufactured under strict Good Manufacturing Practice (GMP) conditions and supplied in compliance with USP, BP, and IP pharmacopoeia standards. The compound has a well-established safety and efficacy profile, with decades of clinical and public health use supporting its role in nuclear emergency preparedness.
KI is procured by national health authorities, defence organisations, nuclear regulatory agencies, hospital pharmacies, and emergency preparedness programmes. It forms a core component of nuclear countermeasure stockpiles alongside other agents such as Prussian Blue for radioactive caesium exposure and Potassium Iodate (KIO3).
How Potassium Iodide Protects Against Radioiodine Exposure
When a nuclear event releases radioactive iodine (primarily Iodine-131) into the environment, the thyroid gland absorbs it rapidly because the thyroid cannot distinguish between radioactive and stable iodine. This uptake can lead to thyroid cancer and other thyroid disorders, particularly in children and young adults. Potassium Iodide works through a mechanism known as thyroid blocking: by saturating the thyroid gland with stable iodine before or shortly after exposure, KI prevents the gland from absorbing the radioactive isotope.
The effectiveness of KI is time-dependent. The WHO recommends administration prior to exposure or as soon as possible within the first 24 hours following exposure for maximum protective effect. Pre-exposure dosing provides near-complete thyroid blocking, while administration within 2 hours of exposure still offers approximately 80% protection. Beyond 24 hours, efficacy diminishes significantly.
The World Health Organization recommends that countries with nuclear power installations or those within range of potential cross-border radiological exposure maintain national stockpiles of Potassium Iodide for rapid distribution to at-risk populations. Strategic pre-positioning of KI in hospitals, emergency centres, and community distribution points is considered a best practice in nuclear emergency preparedness planning.

Frequently Asked Questions
What is the difference between Potassium Iodide and Potassium Iodate?
Both Potassium Iodide (KI) and Potassium Iodate (KIO3) are stable iodine compounds used for thyroid blocking in nuclear emergencies. KI is more widely referenced in FDA and WHO guidelines, while KIO3 offers superior stability in tropical climates and is preferred in several national stockpile programmes. Both are effective thyroid blocking agents when administered at the correct dosage. Learn more about Potassium Iodate (KIO3)
What pharmacopoeia grades do you supply?
We supply Potassium Iodide tablets and oral solution in USP (United States Pharmacopeia), BP (British Pharmacopoeia), and IP (Indian Pharmacopoeia) grades. Specific grade requirements can be confirmed at the time of inquiry to ensure alignment with your regulatory and procurement standards.
Can you supply with custom labelling for national stockpile programmes?
Yes. We offer custom labelling, packaging, and branding options tailored to national stockpile requirements, government distribution programmes, and institutional procurement mandates. Contact our team to discuss your specific labelling and packaging needs.
What is the typical shelf life?
Potassium Iodide tablets supplied by Golden Hour Pharma carry a shelf life of 5 years from the date of manufacture, when stored under recommended conditions (below 25 degrees Celsius, protected from light and moisture). Stability data and storage guidelines are provided with every shipment.
Do you supply in bulk for government programmes?
Yes. Golden Hour Pharma actively supports government and institutional procurement programmes across Africa, MENA, and Latin America. We accommodate large-volume orders with competitive institutional pricing, flexible packaging, and coordinated logistics for national distribution.
