What the AI looks for in Iodine Mineral Supplements
- Dose near the RDA
- Adult RDA is 150 mcg (220 mcg in pregnancy, 290 mcg while breastfeeding). Upper limit is 1,100 mcg/day. Both too little and too much iodine disrupt thyroid function.
- Standardized content
- Buy only kelp or seaweed products that state a fixed iodine amount per serving. Iodine in raw seaweed varies widely and can be extremely high.
- Check prenatals and multis
- Many prenatals already include 150 mcg. Avoids doubling up.
Brands that matter
- NOW Foods: Standardized kelp at RDA-level iodine.
- Pure Encapsulations: Iodine products with stated doses.
What to avoid
- Milligram-dose iodine 'protocol' products such as high-strength Lugol's-style tablets
- Unstandardized seaweed powders
- Self-treating suspected thyroid problems with iodine
Questions
Do I need iodine if I use sea salt?
Sea salt and Himalayan salt are not reliably iodized. Only salt labelled 'iodized' gives meaningful iodine.
