USP-grade Potassium Iodide 130 mg -the FDA-recognized thyroid-blocking dose, also used for daily iodine repletion in deficiency and as preparation for thyroid procedures.
Why It Works
Why Iodine Is Non-Negotiable for Thyroid Health
Required for Thyroid Hormone Production
Iodine is the core atom in both T3 (triiodothyronine) and T4 (thyroxine). Without adequate iodine, the thyroid cannot synthesize these hormones, and the downstream effects -fatigue, weight gain, cold sensitivity, brain fog -follow.
Regulates Metabolism System-Wide
T3 and T4 regulate the basal metabolic rate of virtually every cell in the body. Adequate iodine intake helps maintain the thyroid hormone output that keeps metabolism, body temperature, and energy production running at the right level.
Supports Cognitive Development and Function
Iodine deficiency is the leading preventable cause of cognitive impairment worldwide. In adults, maintaining adequate levels supports mental clarity, memory consolidation, and neurological balance.
FDA-Recognized Thyroid Blocking Dose
The 130 mg dose is specifically recognized by the FDA and WHO as the standard adult dose for thyroid protection in the event of radioactive iodine exposure. By saturating the thyroid with stable iodine, it blocks the uptake of radioactive iodine-131 for approximately 24 hours.
Supports Immune and Cellular Balance
Iodine has roles beyond the thyroid -it contributes to normal immune function and helps maintain the integrity of glandular tissue throughout the body. Adequate levels support cellular health and antioxidant balance in thyroid tissue.
USP-Grade Purity
Our Potassium Iodide is manufactured to United States Pharmacopeia (USP) standards, ensuring consistent dose accuracy and pharmaceutical-grade purity -important for a mineral where dose precision matters.
Thyroid Blocking Efficacy
The Science Behind the 130 mg Dose
The 130 mg dose is the established adult dose for thyroid protection. Published pharmacological data shows that a single 130 mg dose of potassium iodide effectively saturates the thyroid gland, blocking uptake of radioactive iodine-131 by approximately 98% for up to 24 hours. This is the dose recognized by the U.S. Nuclear Regulatory Commission and WHO.

What to Expect Over 3 Months
Foundation
Month 1
For thyroid support use: in the first weeks, people with existing mild iodine insufficiency often notice improved energy and reduced cold sensitivity as thyroid hormone production normalizes. These early changes are gradual -the thyroid is slow to respond to replenishment.
Important: this product is not intended to replace a comprehensive thyroid health evaluation. If you suspect hypothyroidism, work with your physician to measure TSH, free T3, and free T4 levels.
