Iodine
Potassium Iodide — typical dose 150 mcg
We don’t sell Iodine. Whether you actually need it — and at what dose — depends on your bloodwork. Get your analysis to find out.
What it does
Iodine is essential for thyroid hormone production — the master regulator of metabolism, energy, and body temperature. Potassium iodide provides a stable, consistent dose. Deficiency is more common than people think, especially in those who avoid iodised salt, dairy, or seafood. Even mild deficiency can cause fatigue, weight gain, and cognitive sluggishness.
Key benefits
- Thyroid function
- Metabolism regulation
- Cognitive clarity
- Energy levels
The evidence
WHO estimates 2 billion people have inadequate iodine intake. Australian studies show re-emerging deficiency, particularly in older adults on restricted diets.
