Iodine
Essential Mineral for Thyroid and Immune Health
Overview
Iodine is essential for thyroid hormone production, which regulates metabolism throughout the body, including immune function. Beyond the thyroid, iodine plays direct roles in immune defense - it's concentrated in immune cells and has antimicrobial properties.
Key Benefits
- Essential for thyroid hormone production
- Supports immune cell function
- Has direct antimicrobial properties
- Concentrated in and used by white blood cells
- Supports healthy metabolism
How It Works
Thyroid hormones regulate the metabolic activity of all cells, including immune cells. Additionally, immune cells concentrate iodine and use it to produce antimicrobial compounds. Iodine can be incorporated into proteins and lipids in ways that enhance immune defense.
Typical Dosage
RDA is 150mcg for adults. Therapeutic doses range from 200mcg to several milligrams, depending on individual needs and under professional guidance. Kelp and seaweed provide natural iodine sources.
Sources
- Seaweed and kelp
- Seafood
- Iodized salt
- Dairy products
- Supplements (potassium iodide, nascent iodine)
